In Emergency Room, Pharmacists Slash Rate of Drug Errors
A
dd a study at the University of New Mexico, Albuquerque, to the growing body of evidence that demonstrates how on-site pharmacists improve safety in the emergency department (ED). When researchers compared medication error rates at the university’s level 1 trauma center with and without a pharmacist present, they found that 13 times more errors had been reported when there was no pharmacist reviewing drug therapy. Pharmacists are on-site at the 68-bed academic ED for 10 hours per day, where they attend all major trauma and resuscitations. Over the course of three months in 2009, 242 patients were admitted while pharmacists were present, and medication errors were recorded for six (2.5%) of them. By contrast, 452 patients presented when pharmacists were absent, and

Antibiotic Stewardship Made Simple: Pointers for Small Sites Chicago—The prospect of launching an in-depth antimicrobial stewardship program (ASP) can be daunting—especially given the continuing financial pressures on health systems. Fortunately, smaller-scale strategies can help ensure proper antibiotic use, improve clinical outcomes and save health care dollars, according to research presented at the 51st annual Interscience Conference on Antimicrobial Agents and Chemotherapy (ICAAC).

Is That Lung Cancer Medication The Right One for Your Patient?
L
ung cancer patients are typically given drug regimens based largely on the outcomes of large, randomized clinical trials. But those trials may not be valid for a significant percentage of your hospital’s patient base—women, minorities and the elderly. In a study released at the recent 14th World Conference on Lung Cancer, researchers from the FDA reported that enrollment in major clinical trials of agents approved to treat non-small
cell lung cancer (NSCLC) significantly underrepresents these three groups. Between January 2000 and December 2010, the investigators reviewed 10 national and international trials for agents approved to treat NSCLC. They found the following: • Individuals over the age of 65 years made up just 36% of the drug trial population, but represent 73% of U.S. lung cancer patients.

WARNING: SPINAL/EPIDURAL HEMATOMA
Epidural or spinal hematomas may occur in patients who are anticoagulated with low molecular weight heparins (LMWH) or heparinoids and are receiving neuraxial anesthesia or undergoing spinal puncture. These hematomas may result in long-term or permanent paralysis. Consider these risks when scheduling patients for spinal procedures. Factors that can increase the risk of developing epidural or spinal hematomas in these patients include: • Use of indwelling epidural catheters • Concomitant use of other drugs that affect hemostasis, such as non-steroidal anti-inflammatory drugs (NSAIDs), platelet inhibitors, other anticoagulants • A history of traumatic or repeated epidural or spinal punctures • A history of spinal deformity or spinal surgery Monitor patients frequently for signs and symptoms of neurological impairment. If neurological compromise is noted, urgent treatment is necessary. Consider the benefits and risks before neuraxial intervention in patients anticoagulated or to be anticoagulated for thromboprophylaxis.

he short-term use of nonsteroidal anti-inflammatory drugs (NSAIDs) could pose serious danger to individuals with preexisting heart disease, according to a new study (Circulation 2011;123:22262235). Most NSAIDs were associated with a significantly increased risk for recurrent myocardial infarctions and death, said researchers. Despite contraindications in patients with existing cardiovascular disease, many are still given short-term courses of NSAIDs. Based on their results, the researchers did not recommend the use of NSAIDs, either short- or long-term, among patients who had previous heart attacks. “Our results indicate that there is no apparent safe therapeutic window for NSAIDs in patients with prior heart attack,” said Anne-Marie Schjerning Olsen, MB, lead author of the study and research fellow at Copenhagen University in Denmark. The study included a group of patients (N=83,677) older than age 30 years who had suffered heart attacks during a 10-year period. Researchers reported a 45% increase in risk for death and recurrent heart attacks within as little as one week of NSAID therapy. The number increased to 55% after three months of treatment. Although almost all NSAIDs were linked to an increased safety risk, the traditional NSAID diclofenac was associated with an almost three-times-higher risk than any of the other NSAIDs studied. Researchers also noted that the use of over-thecounter NSAIDs was unlikely to have a major impact on the study results. Researchers suggested that in the event that NSAID therapy is necessary, doctors should limit use to the “absolute minimum” in patients with prior heart disease. —PPN Staff

Weekly High-dose Statin Comparable to Daily Dosing New Orleans—High-dose rosuvastatin given once per week led to improvements in serum lipids that were comparable to those achieved with daily doses of atorvastatin 10 mg, in a small study presented at the annual meeting of the American College of Cardiology. “Based on these findings, we think a high-dose weekly statin regimen may be an alternative for patients with major barriers to standard daily therapy,” said
‘We saw this as a means of addressing issues of [statin] adherence and cost, which can be barriers to successful treatment.’ —James M. Backes, PharmD principal investigator James M. Backes, PharmD, of the University of Kansas Atherosclerosis and LDL-Apheresis Center and the University of Kansas
School of Pharmacy, in Kansas City. Dr. Backes noted that testing the extended dosing regimen made sense, based on the types of patients he has
been seeing in his clinical practice. “Our clinic is referred many complex cases, including patients who cannot tolerate statins,” he explained. “A few years ago, we started using these statins every other day and then once a week in statin-intolerant patients, and the logical next step was to see what we could achieve by cranking up a weekly dose in statin-naive patients without a history of intolerance. We saw this as a means

of addressing issues of adherence and cost, which can be barriers to successful treatment.” “Also, as pharmacists I think we are more conservative with medications, and I am concerned about what happens 30 years down the road,” Dr. Backes added. “Atorvastatin, for example, has been on the market since 1998, and we are now seeing blips of diabetes. Maybe less drug exposure might be better.”

study, 10 patients received rosuvastatin (Crestor, AstraZeneca) 80 mg per week and 10 received atorvastatin 10 mg per day. Baseline mean low-density lipoprotein cholesterol (LDL-C) levels were 148 mg/dL and 151 md/dL, respectively (P=0.847). Lipid profiles and high-sensitivity C-reactive protein (hsCRP) were assessed at baseline and one to four and five to eight days after the last dose. Both treatments produced significant reductions in total cholesterol (TC) and LDL-C from baseline at each assessment point, Dr. Backes reported. Final mean LDL-C levels were 105 mg/dL in the high-dose weekly rosuvastatin group and 109 mg/dL in the daily atorvastatin group (P=0.835). Percentage changes after treatment with rosuvastatin and atorvastatin, respectively, were –23% and –20% in TC; –29% and –29% for LDL-C; –6% and no change in high-density lipoprotein cholesterol (HDL-C); –20% and –20% in TC/HDL-C ratio; –3% and –5% in triglycerides; and –19% and +14% in hsCRP levels. The higher hsCRP levels seen with atorvastatin did not differ significantly from rosuvastatin, and may have been due to two patient outliers with “noncardiovascular inflammation,” Dr. Backes suggested. At a mean time of 2.3 days after the last statin dose, LDL-C levels were reduced by 34% with rosuvastatin and 35% with atorvastatin. At a mean time of six days after the last dose, the changes were 25% and 22%, respectively. These were highly significant changes from baseline (P<0.001) but the betweengroup differences were not statistically significant, he noted. Each regimen was well tolerated. One patient on rosuvastatin and three on atorvastatin developed moderate myalgias that resolved with treatment discontinuation. There were no changes in liver enzymes. “The high potency and prolonged halflife of rosuvastatin (19 hours) is a potential explanation for its prolonged efficacy as a weekly regimen,” Dr. Backes said.
More Study Needed C. Michael White, PharmD, professor and interim head of the Department of Pharmacy Practice at the University of Connecticut, in Storrs, said that “this is an interesting study but a small sample size. Future studies should determine if compliance with once-weekly cardiac medications is better than once-daily medications.” Additionally, Dr. White cautioned that clinicians should not interpret these findings as an acceptance of statin doses that are not yet FDA-approved, without further evidence of their safety. Drs. Backes and White reported no relevant conflicts of interest.

LUNG CANCER continued from page 1
• Of trial enrollees, 68% were men and 32% were women. But according to the National Cancer Institute’s (NCI) Surveillance, Epidemiology and End Results (SEER) data, women represent 42% of all NSCLC patients. • Just 2% of trial participants were black, despite African Americans developing lung cancer at higher rates (72.7 per 100,000) than whites (68 per 100,000). Although troubling, these findings should not come as a surprise to anyone—and the issue isn’t confined to lung cancer research, said Joy Lewis, DO, PhD, assistant professor of family and community medicine and director of the Practice-Based Research Network at A.T. Still University School of Osteopathic Medicine in Mesa, Ariz., who has studied the issue of enrollment of the elderly in clinical trials. In 2003, while a researcher at RAND Health, she led a retrospective analysis of patient and trial characteristics for 59,300 patients enrolled into 495 NCIsponsored, cooperative group trials, active from 1997 through 2000. Published in the Journal of Clinical Oncology, her findings closely tracked the FDA researchers’ recent results: Overall, only 32% of participants in Phase II and III clinical trials were elderly, although elderly people account for 61% of U.S. cancer cases (J Clin Oncol 2003;21:1383-1389).
And a cross-sectional, populationbased analysis of all participants in therapeutic nonsurgical NCI Clinical Trial Cooperative Group breast, colorectal, lung, and prostate cancer clinical trials from 2000 through 2002, published in the Journal of the American Medical Association, found that not only were women, the elderly and minorities underrepresented in these trials, the situation seemed to actually be getting worse rather than better (JAMA 2004;291:2720-2726). “Although the total number of trial participants increased during our study period, the representation of racial and ethnic minorities decreased,” they noted. These disparities in representation can mean real problems in terms of incorporating the results of trials into clinical practice. Some drugs may have a different side-effect profile in women from that in men, for example, a fact that would be harder to tease out when men represent the lion’s share of enrollees. And elderly patients may be more vulnerable to a drug’s toxicities than younger patients. Before investigators can improve this picture, they must first understand what the actual barriers are that impede these patient groups from enrolling in trials, said Lynne Nguyen, MPH, director of the Minority & Women Clinical Trials Recruitment Resource in the Department of Health Disparities Research at the University of Texas MD Anderson Cancer Center, in Houston. “A common mistake made in academia
‘A fundamental step in applying the principles of evidence-based medicine is that when you look at a published study, you have to ask if the results apply to your patient. If the people in that study have fundamental differences from your patient, then the answer is no.’
—Joy Lewis, DO, PhD
‘Are we writing protocols so that people have to come into the medical center three times a week for blood draws that take an hour each time, so they have to take time off work and pay $15 to park?’
—Lynne Nguyen, MPH
is thinking too simply about the barriers facing our populations of interest,” Ms. Nguyen explained. “For example, for African Americans, we cite incidents such as the Tuskegee syphilis studies and say that there is a mistrust and fear of researchers among this community as a result. Of course, that’s true. But—are we looking at our own barriers, the ones we construct? Are we writing protocols so that people have to come into the medical center three times a week for blood draws that take an hour each time, so they have to take time off work and pay $15 to park?” Ms. Nguyen also cited health literacy as a key barrier for all populations, but particularly for the elderly. “We know from national health literacy surveys that people aged 65 and older have the lowest levels of health literacy. Are we writing consent forms in a way that’s understandable?” she asked. “And what about the legal piece of the consent form, written by lawyers? That’s the piece that causes mistrust. People read it and when they get the gist, they see that the institution is protecting its own interests, not theirs. That’s a significant issue.” Many trial protocols end up automatically excluding seniors in a way that may not be necessary, said Dr. Lewis. “Some exclusion criteria are used again and again [but] the criteria need to be evaluated in the context of each trial,” she noted. “For example, 41% of Phase II and 47% of Phase III trials have any history of congestive heart failure as an exclusion criterion. Is that always necessary? Are you using a cardiotoxic drug? Can you be more precise and say that you need an ejection fraction or cardiac output above a certain level?” Although exclusion criteria are there for a reason, Dr. Lewis said, due diligence should be taken in developing each screening instrument. “Make sure the investigators justify the use of each specific exclusion criteria for each specific study.” If that were to happen, and if this critical review resulted in fewer restrictions,
participation by the elderly in trials should increase markedly, Dr. Lewis said. “If you relax organ system and functional status exclusions, our model predicts 60% participation for the elderly, which is much more representative of the population of cancer patients generally.” Of course, researchers want to recruit the healthiest participants to their trials because they have the best chance of being successful with the drug. “But in reality, who is more likely to have cancer? Older people,” said Ms. Nguyen. “And they are the ones with all these other conditions. If you test drugs in people without these conditions, how generalizable are your results going to be?” Rather than focusing on changing how patients feel about clinical trials, Ms. Nguyen stressed, the emphasis must be on changing how trials are conducted in order to make recruitment more open to these groups. “We can’t change the patient’s economic situation. We can educate, but we can’t change core beliefs. But we can reduce inequities in our own internal system, and that’s what we’ve got to work on.” In the meantime, clinicians are well advised to read the literature closely, with an eye toward the “methods” section of each trial. “A fundamental step in applying the principles of evidencebased medicine is that when you look at a published study, you have to ask if the results apply to your patient. If the people in that study have fundamental differences from your patient, then the answer is no,” Dr. Lewis said. “That may make it difficult to generalize results related to efficacy and toxicity for your female patients, your minority patients, and in particular your elderly patients.” That doesn’t mean that they can’t receive the same drugs, of course. But it does mean that clinicians should be aware that the outcomes they expect based on the trial population may not, in fact, be the outcomes they get in the real world. —Gina Shaw

NDC: 59148-020-50
NDC: 59148-021-50
Unique oral treatment for clinically significant hypervolemic and euvolemic hyponatremia
100 %
of physicians surveyed (N=57) would recommend SAMSCA to a colleague 1 In this same survey (patient cases; N=150), physicians were satisfied or very satisfied with SAMSCA 90% of the time1
Indication and important limitations • SAMSCA is indicated for the treatment of clinically significant hypervolemic and euvolemic hyponatremia (serum sodium <125 mEq/L or less marked hyponatremia that is symptomatic and has resisted correction with fluid restriction), including patients with heart failure, cirrhosis, and Syndrome of Inappropriate Antidiuretic Hormone (SIADH) • Patients requiring intervention to raise serum sodium urgently to prevent or to treat serious neurological symptoms should not be treated with SAMSCA. It has not been established that raising serum sodium with SAMSCA provides a symptomatic benefit to patients
Important safety information SAMSCA should be initiated and re-initiated in patients only in a hospital where serum sodium can be monitored closely. Too rapid correction of hyponatremia (e.g., >12 mEq/L/24 hours) can cause osmotic demyelination resulting in dysarthria, mutism, dysphagia, lethargy, affective changes, spastic quadriparesis, seizures, coma and death. In susceptible patients, including those with severe malnutrition, alcoholism or advanced liver disease, slower rates of correction may be advisable. Contraindications: Urgent need to raise serum sodium acutely, inability of the patient to sense or appropriately respond to thirst, hypovolemic hyponatremia, concomitant use of strong CYP 3A inhibitors, anuric patients. • Subjects with SIADH or very low baseline serum sodium concentrations may be at greater risk for too-rapid correction of serum sodium. In patients receiving SAMSCA who develop too rapid a rise in serum sodium or develop neurologic sequelae, discontinue or interrupt treatment with SAMSCA and consider administration of hypotonic fluid. Fluid restriction should generally be avoided during the first 24 hours • Dehydration and hypovolemia can occur, especially in potentially volume-depleted patients receiving diuretics or those who are fluid restricted. In patients who develop medically significant signs or symptoms of hypovolemia, discontinuation is recommended • Gastrointestinal bleeding in patients with cirrhosis: Use in cirrhotic patients only when the need to treat outweighs this risk • Avoid use with: CYP 3A inhibitors and CYP 3A inducers. Reduced dose of SAMSCA may be needed if used with P-gp inhibitors • Co-administration with hypertonic saline is not recommended • Monitor serum potassium in patients with levels >5 mEq/L and in those receiving drugs known to increase serum potassium Commonly observed adverse reactions: (SAMSCA vs placebo) thirst (16% vs 5%), dry mouth (13% vs 4%), asthenia (9% vs 4%), constipation (7% vs 2%), pollakiuria or polyuria (11% vs 3%) and hyperglycemia (6% vs 1%).

‘We’re spending more money on antimicrobials, but we’re seeing improved outcomes and lower mortality.’
continued from page 1
Working closely with an infectious disease physician, Dr. Leuthner tried to identify interventions that could improve care and save money at the same time. “That’s where we found longduration antibiotics,” she explained. At the time, the hospital had no ASP, and patients at Yuma given IV antibiotics stayed on those medications for an average of 16 to 20 days. Dr. Leuthner instituted a multipronged intervention that included new dosing strategies and hand-hygiene awareness, as well as staff education on issues such as colonization versus active infection, empiric coverage versus deescalation of therapy, and durations of therapy and duplications of therapy. But the centerpiece of the plan, which she detailed during a session at the ICAAC annual meeting, was a “10-day hard stop” for all antibiotics. “In many cases, patients would be on IV antibiotics until the day they walked out of the hospital, which could be a very long time,” she told attendees. In September 2008, that all changed. Orderentry forms were modified so that once a patient had been on antibiotics for 10 days, the physician could not renew the order but instead had to create a new one. “The day before the stop, we insert a note on bright red paper into the patient’s chart,” Dr. Leuthner said. The “IV Antibiotic Stop Notice” reads: “An antibiotic order for this patient will be at its automatic 10-day expiration tomorrow. The recommended duration of antibiotic therapy is 10 days for most infections. Excessive antibiotic use may lead to selection of resistant organisms and increased antibiotic toxicity. In addition, failure to respond appropriately within the 10-day timeframe may indicate a need to reassess your diagnosis or change antibiotics. Please evaluate your patient to determine if there is clinical evidence to justify continued antibiotic therapy. If your clinical reassessment indicates that the benefits of continued antibiotic therapy outweigh the risks, a completely new order must be written. If you have any questions, a member of the anti-infective team is available for discussion.” Surprisingly, Dr. Leuthner said, the new system met with little resistance. “We educated the physicians ahead of time, and because most of the activity is being done behind the scenes by pharmacists and nurses, their world hasn’t changed too much except for this little speed bump.” Physicians also can bypass the automatic 10-day stop at the time of prescription, if need be. “If you know that the order needs to go for 42 days, you can write ‘for 42 days’ in the order,

‘Most institutions already have some policy in place that has a designated stop time for certain drugs; all you have to do is change it to a set duration and plug in antibiotics.’ —Kimberly Leuthner, PharmD

which will bypass the automatic stop,” she explained. The results have been impressive. Overall duration of therapy has dropped by between three and five days. Previously, about 90% of antibiotic orders were renewed; now, the rate is less than 50%. The dispensing rate has dropped for every type of antimicrobial prescribed at Yuma. And as a result, the rate of organisms isolated has also been reduced (Table 1). “It’s very simple,” Dr. Leuthner said. “All we had to do is program the pharmacy computer system to do this. Most institutions already have some policy in place that has a designated stop time for certain drugs; all you have to do is change it to a set duration and plug in antibiotics.” The biggest expense associated with the program? The red paper that the 10-day stop notice is printed on. Elizabeth Dodds Ashley, PharmD, MHS, BCPS, associate director for clinical pharmacy services and infectious diseases pharmacist at the University of Rochester Medical Center in Rochester, N.Y., praised the initiative. “[Dr. Leuthner’s] data show that everything is moving in the right direction, and I anticipate that it will continue,” she said. “The littlest thing can make a big difference. It’s not just about big complicated programs with lots of full-time staff. You have to be creative when you have limited resources, and it’s great to have data from smaller programs.”
Using PD Data To Establish Optimal Carbapenem Choice Carbapenems, a class of broadspectrum antibiotics that are effective against gram-negative infections, are a mainstay of therapy for people with serious hospital-acquired infections. For about 28 years, The Ohio State University Medical Center’s formulary has contained imipenem as its carbapenem of choice. “It was about 71% susceptible to our Pseudomonas isolate,” said Debbie Goff, PharmD, FCCP, specialty practice pharmacist in infectious diseases at Ohio State, in Columbus, and a speaker at the ICAAC meeting. “When meropenem [Merrem, AstraZeneca] and doripenem [Doribax, Janssen] came onto the market, we evaluated those— they were a few percentage points

Dr. Goff asked David Nicolau, PharmD, FCCP, director of the Center for AntiInfective Research and Development at Hartford Hospital in Hartford, Conn., to conduct a Monte Carlo analysis of Ohio State’s isolates to definitively establish the optimal carbapenem choice and dose (Table 2, page 11). “Pharmacodynamic modeling showed us that doripenem was the best carbapenem given by extended infusion,” Dr. Goff said. “While all three had improved results with extended infusion, doripenem’s were the best. In addi-

better, but not enough to make a formulary change from a 20-year-old drug that everyone was used to using.” But antibiotic resistance in Ohio State’s intensive care unit (ICU) continued to increase, as it is doing everywhere. Dr. Goff and her team decided that they wanted to switch to an extended-infusion carbapenem, which forced them to study the data: Would meropenem or doripenem be more effective?

tion, meropenem and imipenem only have four-hour stability at room temperature, and given that we’re a 1,200bed hospital, that’s just logistically not feasible. We were able to go from our current imipenem 30-minute infusion regimen at about 67% CFR [cumulative fraction of response] to about 94% CFR with doripenem by extended infusion. It costs more, but it’s not about finding the least expensive drug, but about the best. We’re now in the process of doing an outcomes study to validate that this [strategy] results in better patient care.” Dr. Goff and her colleague, Karri A. Bauer, PharmD, BCPS, specialty practice pharmacist, infectious diseases, The Ohio State University Medical Center, presented the results of another study at ICAAC, “Extended Infusion

“Using pharmacodynamic data to dose your drugs has been more widely accepted in recent years, but what [Dr. Goff ] has done here is take the concept we usually apply to dosing and applied it to the formulary,” Dr. Dodds Ashley said. “I’ve heard of some centers doing this, but this is the first paper I’ve seen published on it suggesting formulary status. It’s the first time I’ve seen a true recommendation that you should be picking your formulary drugs based on PD targeting.” In the studies presented at ICAAC, she added, stewardship programs are using data derived from population analyses for one-stop interventions that can touch every patient in the hospital. “That’s what we need to start thinking about: boots-on-the ground stewardship that can be applied at hospitals of any size.” —Gina Shaw

Preventing Nosocomial Infections Saves Lives, Money T
he use of an evidence-based prevention program for nosocomial infections leads to significant cost savings for the hospital, according to new data. Previous analyses of the Keystone ICU Project have shown its efficacy in preventing hospital-acquired infections (HAIs). But to implement a new intervention or program, hospitals require proof that the investment will yield a positive economic return within a certain period of time. “It seems strange to say, ‘well you’re saving lives, but how much does it cost us?’ but at some point in the health care system that’s an important consideration,” said Hugh Waters, PhD, adjunct associate professor, Johns Hopkins Bloomberg
School of Public Health in Baltimore, lead author of the economic analysis. Dr. Waters and colleagues sought to make a business case for the Keystone ICU Project by comparing its cost ($161,584 per year, which includes initial implementation costs) with the average cost of treating a catheterrelated bloodstream infection (CRBSI) or case of ventilator-associated pneumonia (VAP)—$36,500 and $10,000,
respectively. The intervention costs an estimated $3,375 per infection averted, leading to $1.1 million in annual savings for the typical hospital (Am J Med Qual 2011;26:333-339). The savings were derived from a 2010 observational study of the Keystone ICU Project in 106 ICUs across 67 hospitals (BMJ 2010;340:c309). The authors found that the intervention reduced the rate of CRBSIs from 7.7 to

lostridium difficile infection (CDI) is increasing in incidence, severity, and mortality; the annual financial
burden of CDI in the United States
is estimated to be more than $1 billion.1 This review discusses the changing epidemiology, transmission, risk factors, diagnostic tools, and treatment of both index and recurrent CDI.
Hypervirulent strains of C. difficile throughout North America and Europe have contributed to this epidemic—an increase in treatment failures for both index and recurrent infections is driving research to discover more effective treatment strategies. As a result, a variety of therapies, including antibiotic and probiotic regimens, immunotherapy, investigational vaccines, and fecal microbiota transplant (FMT), all have been used to treat CDI with varying success.2-5
Epidemiology Incidence The incidence of CDI in the United States is increasing at an alarming rate. Based on data from various medical centers throughout the United States, one study estimated that the incidence doubled between 1996 and 2003 from 31 to 61 per 100,000 population.6 During a similar time frame, a single center in St. Louis, MO, showed a parallel trend, with the incidence of CDI increasing from 8.5 to 15.9 per 1,000 hospital admissions.7 An estimated 500,000 cases of CDI occur in the United States each year, causing 15,000 to 20,000 deaths annually.1 This trend is not isolated to North America, however. A Belgian study reported a 3.75-fold increase in the incidence of CDI from 2000 to 2003 compared with 2004 to 2007.8 Virulence The current manifestations of CDI are quite different from those detailed in the hallmark publications by Hall and O’Toole in 19359 and those of Bartlett and colleagues in the late 1970s.10 Today,
hypervirulent strains that cause severe disease, as well as community-acquired (CA) infections not associated with antibiotic use, are routinely observed. Severe disease likely results from hypervirulent strains such as the North American pulsed-field type 1 (NAP1), restrictionendonuclease analysis type BI, and polymerase chain reaction (PCR) ribotype 027 (collectively referred to as NAP1/BI/027) strain, which is resistant to fluoroquinolones.1,11 This strain produces 10 times more toxin A and up to 23 times more toxin B than other strains and also produces a third toxin, referred to as binary toxin.12 Some authorities believe that it is to blame for the overall increase in the virulence of CDI. C. difficile was previously considered a hospital-acquired (HA) infection, but with the emergence of the NAP1/BI/027 strain, CDI increasingly is being observed in the community. Although there do not seem to be significant differences in the presentation and outcomes for patients with CA-CDI compared with HA-CDI,13 groups previously considered at low risk for CDI currently are becoming increasingly infected, such as young, healthy individuals without prior exposure to hospitals or antibiotics, peripartum women,1,11 patients with inflammatory bowel disease or cirrhosis,7,14 organ transplant patients, and immunocompromised individuals. As more studies look into the changing epidemiology, risk factors, and outcomes for CDI, clinical guidelines for the management of the infection are rapidly changing.15
Risk Factors Various risk factors for disease acquisition and severity are important to consider. Nasogastric tubes, prolonged hospital stays, and exposure to proton pump inhibitors, hydrogen pump blockers, corticosteroids, or other immunosuppressives all are associated with an increased risk for CDI in hospitalized patients.1,11 Risk factors associated with severe CDI and poor outcomes include being aged 65 years or older, fever, nasogastric tube placement, immunosuppression, cognitive impairment, and recent endoscopy.16,17 Peak white blood cell (WBC) counts, peak creatinine levels duringadmission, and WBC counts at the time of admission with CDI all have been associated with an increased risk for colectomy and short-term mortality in patients with CDI.18,19 Of note, patients exposed to corticosteroids within 15 days of CDI diagnosis were found to have a 30-day mortality rate twice that of patients not treated with these agents.20 Reducing patients’ exposure to these factors whenever possible might decrease the risk for both infection and severe disease.
Transmission Understanding the transmission of CDI is key to reducing the frequency of this epidemic and requires some insight into its pathogenesis. Kyne et al described the initial need for normal colonic microbiota to be altered, possibly by antibiotics. Once a person with intestinal flora disturbance ingests C. difficile, it colonizes in the large bowel, leading to the release of toxins A and B in the

Educational Review colon and subsequent symptomatic colitis.21 There are 2 forms of the bacterium: vegetative and spore. The latter can survive on environmental surfaces such as countertops, door handles, faucets, and toilet seats for years. It is the survival ability of the spores that has contributed to the growth and persistence of this epidemic. Preventing the transmission of CDI involves reducing or eliminating the various factors listed above. Antibiotic therapy alters the normal colonic microbiota that serve as a protective barrier against CDI. Most antibiotics predispose patients to CDI, even those used to treat CDI (eg, metronidazole and vancomycin).22,23 The antibiotics most frequently implicated in causing CDI and diarrhea include ampicillin, amoxicillin, cephalosporins, clindamycin, and the fluoroquinolones.24,25 Minimizing the inappropriate use of antibiotics in all patients, especially CDI-susceptible patients (eg, hospitalized elderly patients), can help prevent infection. The incidence of CA-CDI has increased, but HA-CDI is still of major importance when discussing transmission26; patients may infect others in the community upon discharge from the hospital. Between 10% and 30% of hospitalized patients treated with antibiotics are estimated to be colonized with C. difficile.27-29 Throughout the hospital and infected patients’ homes, many hard external surfaces can be contaminated with C. difficile, including toilet seats, doorknobs, countertops, and bedpans. Caregivers must be aware that their stethoscopes, hands, and possibly clothing also may transmit the infection.27.28 Fekety et al wrote guidelines for the prevention of C. difficile transmission that include limiting the use of antimicrobial agents; washing hands before and after interacting with each patient; isolating patients with CDI from uninfected patients; wearing gloves when interacting with all patients with CDI; disinfecting all C. difficile–contaminated objects with sodium hypochlorite, alkaline glutaraldehyde, or ethylene oxide; educating hospital staff about the infection; and practicing good hand hygiene.30 It is important to note that alcohol-based sanitizing agents are not as effective at eradicating CDI as hand washing with soap and water; all caregivers of patients with CDI need to thoroughly wash their hands and even their stethoscopes for effective infection control.31
Diagnosis Testing for CDI should be performed on any patient who has acute diarrhea and who has received antibiotics within 3 months of presentation, or any patient who develops diarrhea within 72 hours of admission to the hospital. It is not recommended to test formed stool because treatment is indicated only for patients with symptomatic diarrhea.29,32 A stool sample should be obtained immediately after a bowel movement and submitted to the laboratory in a watertight container. There are several methods to analyze a stool for CDI, including culture, tissue culture cytotoxicity assay, enzymelinked immunoabsorbent assay (ELISA), PCR, and glutamate dehydrogenase (GDH) testing. ELISA is the most common method used to detect toxin antigens because it is inexpensive, fast (results are usually available in less than 6 hours), and highly specific. The main problem with this test is a relatively low sensitivity (~90%), leading to a slight
risk for false-negative results.33,34 The tissue culture cytotoxicity assay remains the gold standard for CDI diagnosis because of its high sensitivity and specificity35; however, it is not commonly used because it is expensive, requires technical expertise, and results take 1 to 3 days to develop. Because cultures for C. difficile need anaerobic conditions and several days are needed to obtain results, this method is rarely used for nonepidemiologic purposes. PCR assays also are less commonly performed than ELISA because of their price, but this methodology offers a highly sensitive and specific test that is likely to become widely used in the future. In certain institutions, a progression of diagnostic tests is performed. For example, a GDH assay might initially be performed. This test is highly specific for C. difficile. If the assay is negative, then no further testing is performed. If it is positive, an ELISA is performed; if the ELISA is positive, it confirms a toxin-producing form of C. difficile with no further testing required. However, if the ELISA is negative, a PCR is then performed. If the PCR is positive, the patient has toxin-producing C. difficile; negative results indicate that the patient has non–toxin-producing C. difficile. This type of sequenced testing optimizes the specificity of diagnosis and is cost-effective, although perhaps not as expedient as performing only a PCR test. With the observed epidemiologic changes of CDI, there is an increased urgency for more accurate, rapid testing also capable of detecting hypervirulent strains. The FDA recently approved the Cepheid Xpert C. difficile/Epi assay.36 This method offers a rapid test for toxin B and can detect the NAP1/BI/027 strain. Most practicing clinicians must rely on whatever diagnostic tools are available at their local laboratory or institution to test for CDI. Clinicians must understand the risk for false-positive or false-negative results with the methods available at their institution because this information might affect their decision making.
Treatment The first step in managing patients with CDI requires discontinuing any antibiotics that might be contributing to the infection whenever possible;
15% to 25% of cases will resolve without any further therapy.37,38 Because discontinuation of antibiotics is not always feasible—and this conservative measure alone is not appropriate in patients with persistent symptomatic disease—antibiotic therapy and other interventions must be considered. The Table (page 18) gives an overview of current treatment recommendations for CDI. Metronidazole is the first-line treatment for patients with mild to moderate CDI because of its efficacy and low cost. A 2007 Cochrane Review found that metronidazole (usually given as 500 mg orally 3 times daily for 10-14 days) had similar efficacy to vancomycin for non-severe CDI39; however, as the C. difficile epidemic continues to grow, the rate of treatment failure and the number of patients who experience relapses or recurrences are increasing as well. Data from the 1980s and 1990s showed that metronidazole had a low treatment failure rate (<5%),37,40 but recent studies have observed failure rates as high as 38%.41,42 Some blame hypervirulent strains for the reduced efficacy of metronidazole, but a study that compared a cohort from 1998 with one from 2004 to 2006 showed that metronidazole failure rates were similar and remarkably high in both groups (35%).43 Moreover, the incidence of NAP1/BI/027 was similar in patients who were treated successfully with metronidazole (21%) and those who experienced treatment failure (26%; P=0.67).43 Metronidazole is usually well tolerated, but about 1% of patients experience systemic side effects, including nausea and a metallic taste; peripheral sensory neuropathy may be seen with prolonged treatment.37 Because of the risks for birth defects associated with metronidazole, it should not be used in pregnant women. Metronidazole remains the first-line therapy for patients with mild to moderate disease and has the potential benefit of not causing vancomycin-resistant enterococci (VRE). Vancomycin is now considered first-line therapy for patients with moderate to severe CDI. Oral vancomycin has minimal systemic absorption, resulting in high concentrations in the colon, thus minimizing its systemic side effects and theoretically making it an ideal treatment. Zar and colleagues compared the efficacy of metronidazole with that of vancomycin in patients stratified by disease severity. In patients with mild disease, the efficacy of metronidazole was similar to that of vancomycin (90% vs 98%; P=0.36); patients with severe disease were significantly more likely to respond to treatment with vancomycin than with metronidazole (97% vs 76%; P=0.02).41 Vancomycin is indicated for the treatment of moderate to severe CDI in pregnant women, children aged 10 years or younger, and patients who either failed or are intolerant to metronidazole.30 Vancomycin 125 mg 4 times daily is as effective as 500 mg 4 times daily.44 It is recommended to use the lower dose with most patients; the higher dosing is reserved for critically ill patients. In the latter group, vancomycin may be given orally, by nasogastric tube, or via enema while IV metronidazole is administered.
Recurrent CDI Recurrent CDI has been observed in 15% to 30% of patients who successfully completed an initial treatment.45 There are no uniformly accepted criteria for disease recurrence, but most include patients who have repeat Text continues on page 16

symptomatic infection within 2 days to 2 months after completing an appropriate treatment. It is likely that initial treatment failure occurred in some of these patients and that they never fully cleared the infection. Wilcox et al ribotyped strains of C. difficile in index and recurrent disease and found that 56% of recurrences were caused by a different strain from the one that caused the initial infection.46 Most clinicians and authors do not distinguish relapse (ie, same strain) from recurrence (ie, different strain). Regardless of whether the strain that causes CDI recurrence is the same or different from the one that caused the original infection, patients who are unable to generate immunoglobulin G (IgG) against C. difficile toxin A are more likely to have repeat infections.45 Other risk factors for recurrent infection include those listed above for index infection and also being aged 65 years or older, increased WBC counts during initial infection, low serum albumin levels, and antibiotic use between the initial treatment and the recurrent infection.1,11 It seems that the greatest risk factor for recurrent infection is a recurrence itself—up to 65% of patients who have 1 recurrence may have future episodes.47 Treatment of Recurrent CDI When managing patients with recurrent CDI, it is important to eliminate the possibility of postCDI irritable bowel syndrome48 and other causes of diarrhea.45 Similar to the index presentation, once a diagnosis has been confirmed, clinicians should again attempt to limit or eliminate any potential offending antibiotics if possible. If a patient must remain on antibiotics, switching to one that is less commonly associated with CDI is advised, if possible.
Antibiotics In the past, the same 14-day treatment course with the antibiotic used to treat the initial infection was recommended. Recently, however, vancomycin has been recommended for patients with a moderate to severe recurrence, regardless of which initial antibiotic was used. Some authors recommend a 14-day course of vancomycin, but a tapered-pulse therapy regimen is generally being used, despite the absence of robust evidence to prove its value over a standard 14-day course of therapy for either the first or second recurrence of CDI. Tapered-pulse therapy allows the antibiotic-resistant spore form of the organism to convert into the antibiotic-sensitive, vegetative form as the antibiotic is withdrawn slowly and, in the final stages of tapering, is given on alternate days. Theoretically, spores convert to their vegetative form on days when vancomycin is not administered, and vegetative forms are killed on the days when the drug is taken.14 Although this tapered and pulse-dosing regimen is widely used and effective in many patients, the recurring and chronic use of antibiotics to treat recurrent CDI has its downsides, especially in terms of the intestinal microbiota. Vancomycin is a broad-spectrum antimicrobial agent with activity against almost all gram-positive aerobic and anaerobic organisms. As a result, it may increase host susceptibility to CDI by killing many of the normal intestinal microorganisms; its use also
Probiotics By restoring the “balance” of the normal colonic microbiota, probiotics are believed to help restore the “colonization resistance” or protective barrier of intestinal microflora. Saccharomyces boulardii has been the most extensively studied probiotic for recurrent CDI. Surawicz and colleagues conducted a double-blind, placebo-controlled trial that compared placebo or S. boulardii (added during day 7 of treatment) with high-dose vancomycin (2 g/d), low-dose vancomycin (500 mg/d), or metronidazole (1 g/d).3 The placebo or S. boulardii was then continued for 28 days. Patients who received high-dose vancomycin and S. boulardii showed a significantly lower recurrence rate than the placebo/high-dose vancomycin group (16.7% vs 50%; P=0.05), whereas there were no significant differences seen between patients on low-dose vancomycinand those on low-dose metronidazole.3 McFarland et al conducted a meta-analysis looking at all probiotics studied in the prevention of CDI and found that the only probiotic to show a significant risk reduction (41%) for recurrent disease was S. boulardii.49 It is believed that S. boulardii releases a protease that inactivates C. difficile toxin receptors, thereby preventing symptomatic disease.3 Despite this probiotic having no significant adverse side effects, there have been documented cases of immunocompromised patients suffering from fatal fungemia during its use.50 Clinicians should consider the most appropriate conditions for the use of probiotics to prevent recurrent CDI and avoid longterm use of S. boulardii.
Novel Therapies for CDI Along with the increasing virulence of CDI, treatment failure and disease recurrence have become more common. In response to this trend, several new treatments are being studied, including alternative antibiotics, C. difficile toxin–binding resins, monoclonal antibodies against toxins A and B, C. difficile vaccination,2 and FMT. Nitazoxanide Nitazoxanide is a nitrothiazolide that is commonly used to treat intestinal parasites such as cryptosporidia and giardia. A breakdown product of nitazoxanide, tizoxanide, actively inhibits the anaerobic metabolism of C. difficile; because approximately two-thirds of each dose is excreted in the feces, this medication potentially offers an alternative treatment. When the in vitro efficacy of nitazoxanide was investigated in 127 strains of C. difficile (including the most common and most virulentribotypes), it showed excellent bactericidal activity.51 A double-blind, placebo-controlled study that compared nitazoxanide 500 mg twice daily for 7 days with metronidazole 250 mg 4 times daily for 10 days found that 82.4% of patients receiving metronidazole and 89.5% of patients receiving nitazoxanide responded to treatment. The results proved that nitazoxanide is noninferior
to metronidazole for first-line therapy.52 A separate study that investigated patients who failed conventional treatment with metronidazole found that nitazoxanide 500 mg twice daily had a 74% response rate and a 54% cure rate.53 Nitazoxanide appears to have adequate efficacy in the treatment of CDI, but it is not superior to current treatments and thus likely will remain a third-line alternative used after other regimens fail. Rifaximin Rifaximin is a poorly absorbed rifamycin derivative that inhibits bacterial transcription and protein synthesis. Following its FDA approval for traveler’s diarrhea, many uses for this antibiotic have been studied, including small intestinal bacterial overgrowth, hepatic encephalopathy, and CDI. In vitro studies of rifaximin for the treatment of CDI have shown promising results,54 but some studies also have shown the development of rifaximin resistance.55 One small case series of 3 post–liver transplant patients who failed standard initial treatment found that vancomycin followed by a 28-day course of rifaximin (400 mg 3 times daily) resulted in resolution of diarrhea in all patients within 48 hours of treatment; all remained symptom-free at 6-month follow-up.56 Rifaximin 100 to 200 mg twice daily following treatment completion with vancomycin for recurrent CDI also showed efficacy in a separate case series.57 Although these results are encouraging, they must be confirmed with large-scale trials. Currently, the use of rifaximin following vancomycin for the treatment of recurrent CDI is considered to be useful. Fidaxomicin Fidaxomicin, a narrow-spectrum macrocyclic antibiotic, is a promising new antimicrobial treatment for CDI.58 A study that compared fidaxomicin with vancomycin in patients with recurrent CDI found a lower rate of recurrence with fidaxomicin than with vancomycin (20% vs 36%; P=0.045).59 A head-to-head comparison of fidaxomicin 200 mg 3 times daily with vancomycin 125 mg 4 times daily for 10 days found that fidaxomicin was noninferior to vancomycin, with clinical cure rates of 88.2% and 85.8%, respectively. The rates of recurrence were significantly lower in the fidaxomicin group than in the vancomycin group (15.4% vs 25.3%; P=0.005).60 For patients with the NAP1/ BI/027 strain, the rates of clinical cure and recurrence were similar for fidaxomicin (78.7% and 27.1%, respectively) and vancomycin (80.7% and 20.9%, respectively).60 Adverse events from fidaxomicin, although rare, include nausea, vomiting, headache, and abdominal pain. In May 2011, the FDA approved fidaxomicin for the treatment of C. difficile–associated diarrhea.61 Fidaxomicin is a good alternative to vancomycin and is less frequently associated with disease recurrence. Toxin Binders C. difficile toxins A and B are thought to be the main mediators of symptomatic CDI. Theoretically, binding resins should help to control CDI by binding the toxins without altering the colonic microbiota. Using 4 g of binding resin 3 or 4 times daily, previous studies have found varying efficacy, from 36% with colestipol to 68% with cholestyramine.4 Tolevamer was designed as a synthetic polysterol Text continues on page 18

that also is capable of binding C. difficile toxins, but it was shown to be significantly less effective than both vancomycin and metronidazole in clinical trials, resulting in the discontinuation of its production.62 The role of toxin binders in patients with symptomatic CDI likely is as an adjunct to primary antibiotic treatment; toxin binders act to control the symptoms of CDI while another agent treats the active infection. Immunotherapy Patients with elevated levels of serum IgG against toxin A are less likely to develop symptomatic infection,whereas patients with low levels following infection are more likely to have recurrent disease.45 Passive immunization with IV immunoglobulin (IVIG) is another therapeutic intervention that attempts to supplement a patient’s immune response to CDI. Several small studies using IVIG (usually 400 mg/kg of body weight) in patients with severe or recurrent disease have shown mixed results. One trial found up to a 100% response rate,63 whereas others found significantly lower efficacy.64 Antibodies more specific to CDI have been developed as well. Lowy et al conducted a doubleblind, placebo-controlled trial that compared
patients receiving metronidazole or vancomycin alone with those receiving metronidazole or vancomycin in combination with fully human monoclonal antibodies to C. difficile toxins A and B (10 mg/kg of body weight). Overall, patients receiving antibodies in combination with the antibiotic were less likely to have recurrent infections (7% vs 25%; P<0.001). Patients infected with the NAP1/BI/O27 strain showed a trend toward lower rates of recurrence as well (8% vs 32%; P=0.06).5 Targeted antibody treatments seem to be a very encouraging future option in the management of CDI. Fecal Transplantation Fecal transplantation, also known as fecal bacteriotherapy or, preferably, FMT (because we do not know which of the living organisms or metabolic products in stool are effective in the various diseases for which this therapy has been used), is another promising and interesting treatment option. The rationale behind FMT is simple: Antibiotics and other factors disrupt the normal balance of the colonic microbiome, and by reintroducing normal microbiota via donor feces, a balanced “colonization resistance” can be reestablished.21 Compared with stools from patients who had antibiotic-associated diarrhea not associated with C. difficile and
those with just a single episode of CDI,65 patients with recurrent CDI had a decreased species richness in their stool. There was a specific absence of Bacteroidetes and Firmicutes phyla, suggesting that this microbiome “fingerprint” is characteristic of recurrent CDI and that FMT might be a possible treatment modality.65 The clinical use of FMT dates back to 1958, although the bulk of published work, which is still very limited, has come in the last 2 decades.66,67 Initially, retention enemas were the most common technique for FMT, but fecal infusion via duodenal tube,68 rectal tube,69 and colonoscopy70-72 recently have been reported. One case series of 18 patients with CDI (17 had FMT via colonoscopy, 1 via gastrostomy) showed that 15 of 18 patients were cured with no relapses noted. The 3 patients who failed to respond had severe colitis.70 In a series of 12 patients with recurrent or refractory disease in whom donor feces were infused at colonoscopy, all 12 had prompt symptomatic cure within hours to days, with no adverse events.71 In another separate case series of 19 patients with recurrent CDI using a similar technique, 18 of 19 patients immediately responded to treatment. Three patients ultimately had recurrent infection following treatment, but all 3 recurrences occurred

Educational Review immediately after antibiotic treatment, making a de novo infection rather than FMT treatmentfailure the likely cause.72 There is no consensus opinion on the exact technique to perform FMT at this time. The colonoscopic approach is now favored over the fecal enema because enemas only reach the splenic flexure,73 whereas with colonoscopy, the entire colon and ileum can be recolonized, and colonoscopy can elucidate the extent and severity of disease while the treatment is given.72 Regardless, FMT appears to be an effective treatment for refractory or recurrent CDI, with an 89% cure rate in 275 case reports from across the world.74 Further research on FMT is needed to clarify the optimal delivery methods, appropriate donors, and situations most appropriate to use this technique. A large randomized controlled trial, FECAL (Fecal therapy to Eliminate Clostridium difficile–Associated Longstanding diarrhea), is under way in Norway. It compares patients with refractory CDI receiving standard high-dose vancomycin with those receiving high-dose vancomycin and then FMT.60 When the results of the FECAL trial and other studies are published, the role of FMT in the management of CDI will be further clarified.
Conclusion CDI is an epidemic that is rapidly evolving. As we understand more about this infection, its risk factors, its modes of transmission, and potential treatments, we will be better equipped to both effectively prevent new cases and treat existing ones. Currently, many promising treatments beyond metronidazole and vancomycin are available. The most promising of these therapies include fidaxomicin and FMT for treatment of refractory infection and perhaps S. boulardii for the prevention of recurrence following treatment of primary infection.

Indications and usage Voluven is a plasma volume substitute indicated for the treatment and prophylaxis of hypovolemia. Safety information Voluven is contraindicated in patients with a known hypersensitivity to starch, fluid overload, renal failure with oliguria or anuria not related to hypovolemia, those receiving dialysis, severe hypernatremia, severe
hyperchloremia and intracranial bleeding. Avoid fluid overload; adjust dosage in patients with cardiac or renal dysfunction. Monitor kidney function, fluid balance, acid-base balance, coagulation parameters and serum electrolytes. In severe dehydration a crystalloid solution should be given first. Elevated serum amylase levels may occur and interfere with the
diagnosis of pancreatitis. Observe caution in patients with severe liver disease or bleeding disorders. High dosages may cause dilution of blood components. Anaphylactoid/hypersensitivity reactions can occur. Most common adverse reactions (incidence >1%) are pruritus, elevated serum amylase, and hemodilution (resulting in dilution of blood components, e.g., coagulation

BRIEF SUMMARY CONSULT PACKAGE FOR FULL PRESCRIBING INFORMATION
VOLUVEN® (6% HYDROXYETHYL STARCH 130/0.4 IN 0.9% SODIUM CHLORIDE INJECTION) 1 INDICATIONS AND USAGE Voluven® (6% hydroxyethyl starch 130/0.4 in 0.9% sodium chloride injection) is indicated for the treatment and prophylaxis of hypovolemia. It is not a substitute for red blood cells or coagulation factors in plasma. 4 CONTRAINDICATIONS The use of Voluven® is contraindicated in the following conditions: • known hypersensitivity to hydroxyethyl starch [see General Warnings and Precautions (5.1)] • fluid overload (hyperhydration) and especially in cases of pulmonary edema and congestive heart failure • renal failure with oliguria or anuria not related to hypovolemia • patients receiving dialysis treatment • severe hypernatremia or severe hyperchloremia • intracranial bleeding. 5 WARNINGS AND PRECAUTIONS 5.1 General Warnings and Precautions Anaphylactoid reactions (mild influenza-like symptoms, bradycardia, tachycardia, bronchospasm, non-cardiac pulmonary edema) have been reported with solutions containing hydroxyethyl starch. If a hypersensitivity reaction occurs, administration of the drug should be discontinued immediately and the appropriate treatment and supportive measures should be undertaken until symptoms have resolved. [see Adverse Reactions (6)] Fluid status and rate of infusion should be assessed regularly during treatment, especially in patients with cardiac insufficiency or severe kidney dysfunction. In cases of severe dehydration, a crystalloid solution should be given first. Generally, sufficient fluid should be administered in order to avoid dehydration. Caution should be observed before administering Voluven® to patients with severe liver disease or severe bleeding disorders (e.g., severe cases of von Willebrand´s disease). 5.2 Monitoring: Laboratory Tests Clinical evaluation and periodic laboratory determinations are necessary to monitor fluid balance, electrolyte concentrations, kidney function, acid-base balance, and coagulation parameters during prolonged parenteral therapy or whenever the patient’s condition warrants such evaluation. 5.3 Interference with Laboratory Tests Elevated serum amylase levels may be observed temporarily following administration of the product and can interfere with the diagnosis of pancreatitis. At high dosages the dilutional effects may result in decreased levels of coagulation factors and other plasma proteins and a decrease in hematocrit. 6 ADVERSE REACTIONS 6.1 Overall Adverse Reaction Profile From the accumulated clinical development experience, expected adverse reactions after administration of Voluven® occurring in less than 10% of patients are as follows: Immune system disorders (Rare, >0.01% to <0.1%): Products containing hydroxyethyl starch may lead to anaphylactoid reactions (hypersensitivity, mild influenza-like symptoms, bradycardia, tachycardia, bronchospasm, non-cardiac pulmonary edema). In the event of an intolerance reaction, the infusion should be discontinued immediately and the appropriate emergency medical treatment initiated. [see General Warnings and Precautions (5.1)] Skin and subcutaneous tissue disorders (Common, >1 to <10%, dose dependent): Prolonged administration of high dosages of hydroxyethyl starch may cause pruritus (itching) which is an undesirable effect observed with all hydroxyethyl starches. Investigations (Common, >1% to <10%, dose dependent): The concentration of serum amylase can rise during administration of hydroxyethyl starch and can confound the diagnosis of pancreatitis. At high doses the dilutional effects may result in decreased levels of coagulation factors and other plasma proteins and in a decrease of hematocrit. [see Interference with Laboratory Tests (5.3)]
6.2 Adverse Reactions in Clinical Trials Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug may not reflect the rates observed in practice. During clinical development, 471 patients were exposed to Voluven®, and a total of 768 patients received the hydroxyethyl starch 130/0.4 drug substance contained in Voluven® at different concentrations (2%, 4%, 6%, or 10%) and at cumulative doses of several mL up to 66 L1). The mean duration of treatment with hydroxyethyl starch 130/0.4 was 3.9 ± 3.3 days, mean cumulative doses were 3338 ± 3695 mL, and the longest follow-up period was 90 days. In the US trial, 100 patients undergoing elective orthopedic surgery were treated either with Voluven® (N=49) or hetastarch (6% hydroxyethyl starch in 0.9% sodium chloride injection) (N=51) for intraoperative volume replacement. Mean infusion volumes were 1613 ± 778 mL for Voluven® and 1584 ± 958 mL for hetastarch. Adverse reactions observed in at least 1% of patients: In the US trial comparing Voluven® with hetastarch, a possible relationship to Voluven® was reported in five cases in a total of three patients (aPTT elevated, PT prolonged, wound hemorrhage, anemia, pruritus). A possible relationship to hetastarch was reported in five patients (three cases of coagulopathy; two cases of pruritus). The three coagulopathy cases in the hetastarch group were serious and occurred in patients receiving more than the labeled ceiling dose (20 mL/kg), whereas no serious coagulopathy occurred in the Voluven® group. 6.3 Postmarketing Experience The following adverse reactions have been identified during the post-approval use of Voluven® and other types of hydroxyethyl starch solutions. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. The safety profile from postmarketing experience of Voluven® is not different from the profile obtained from clinical trials performed using the product. Based on spontaneous reporting of hypersensitivity reactions, urticaria, bronchospasm, or hypotension were the most frequently reported serious adverse drug reactions for patients treated with Voluven®. With the administration of hydroxyethyl starch solutions, disturbances of blood coagulation can occur depending on the dosage2). 10 OVERDOSAGE As with all plasma volume substitutes, overdosage can lead to overloading of the circulatory system (e.g. pulmonary edema). In this case, the infusion should be stopped immediately and if necessary, a diuretic should be administered. [see General Warnings and Precautions (5.1)] 16 HOW SUPPLIED/STORAGE AND HANDLING Voluven® (6% hydroxyethyl starch 130/0.4 in 0.9% sodium chloride injection) for intravenous infusion is supplied in the following primary container and carton sizes: Polyolefin bag (freeflex®) with overwrap: 500 mL Carton of 15 x 500 mL NDC 0409-1029-01 Store at 15° to 25°C (59° to 77°F).

IV MANAGEMENT continued from page 1
Jamie Kelly President Entropy Research San Diego, California
“People can’t always recognize things as quickly as computers can,” he explained. “But computers aren’t always able to see what a person can. Ideally, technology allows people and computers to work together.” We visited York Hospital on a cold and still-snowy April morning to verify reports of a medication safety breakthrough that, frankly, sounds a little too good to be true—a sort of infusion nirvana on earth. Dr. Baker guided us into the hospital’s state-of-the-art clinical simulation lab saying, “There is no point in building an electronic hospital unless you can accomplish things that you could not achieve with paper. Our infusion management system is a fine example of innovative thinking transcending current practice.” With that we turned our attention to WellSpan’s vice president of patient care services and clinical transformation officer Kris O’Shea, RN, MS, who greeted us warmly, standing before a computer on wheels parked beside an IV pole. She began a tale of two situations—life before and after infusion management.
towels and even their scrubs. After a code, the nurse must then rely on memory and the limited notes available in order to accurately document the infusions administered. This process can take as long as two hours to complete for a single code. Historically, infusion pumps have been unable to communicate infusion status information beyond what was displayed on the pump. As such, the standard practice for managing the supply of titratable infusions from pharmacy to the nursing unit relies on phone calls, faxes or—as was the case at York—electronic health record (EHR) communications initiated by the nurse to the pharmacy. Even with an elec-
the risk for the patient’s blood pressure quickly elevating creates an urgent need.” In the pharmacy, unplanned, urgent requests for infusion preparation and numerous phone calls checking on the status of the infusions’ preparation and delivery diminish operational efficiencies and create additional distractions for pharmacists and technicians. As these reorder requests come into the pharmacy electronically, a number of pharmacists charged with order verification process these requests, and labels are ultimately generated remotely in the IV lab. This process creates a challenge for the pharmacy’s technical staff charged with IV admixture
‘Although infusion medications have a direct impact on patient condition, [traditionally] there is no centralized visibility to realtime effects for nurses and physicians.’ —Hal Baker, MD
Problems With Unconnected Infusion Management “The infusion of IV medications is a complicated process with many steps highly reliant on the diligent performance of a single nurse. The opportunity for error is ever present,” Ms. O’Shea said. In fact, IV medication errors are twice as likely to cause harm to patients as medications delivered by other routes of administration. Wrongpatient errors, a double tap of a key that results in a 10-fold dose error, and the selection of dobutamine instead of dopamine from the smart infusion pump drug library are all inevitable consequences of human nature. With some high-acuity patients receiving up to eight different IV medications simultaneously, the potential for a mistake is high. Clinical risk aside, infusions also take an operational toll on caregivers. Documenting IV medication administrations is an especially time-consuming part of a nurse’s day as each new infusion and rate adjustment must be documented. The process is especially challenging in emergency situations when nurses document under the gun, jotting on paper
inefficiency surrounding the preparation of scheduled continuous and intermittent IVs that are generally pre- SPOTLIGHT ON pared in advance via a TECHNOLOGY set time frame (e.g., all IV medications scheduled to be administered within the next six hours). “The result is that medications are delivered to the unit well in advance of need. Subsequently, the orders for these medications may be discontinued after the infusion has already been delivered,” he said. Pharmacy staff must then collect the medication during a subsequent delivery and return it to the pharmacy for crediting and potential redistribution to another patient, when possible. In some cases, Mr. Gerhart added, returned infusions with limited stability “may be unusable upon return to pharmacy and must be destroyed, resulting in unnecessary waste.” Mr. Gerhart pointed out that this type of batch production in advance of need might present a risk to patient safety as well. When large supplies of infusions are available on the nursing unit in advance of their actual need, he noted, the risk for a wrong patient or wrong medication error increases significantly. Finally, Dr. Baker was quick to point out that infusion data traditionally reside solely within the pump and are not easily synchronized with laboratory results or other device data such as vital signs. “Although infusion medications have a direct impact on patient condition, there is no centralized visibility to real-time effects for nurses and physicians,” he said.

tronic reorder system in place, nurses typically call the pharmacy when an infusion is running extremely low for “peace of mind” that the product that they requested electronically will be prepared and delivered prior to the completion of the current infusion. “With many patients receiving numerous medications, an infusion could run out before the nurse is able to notify the pharmacy,” Ms. O’Shea said. “In the case of a medication like nicardipine,

With 14 years of information amassed in the Cerner Millennium EHR, WellSpan clinicians typically have ready access to a patient’s full medical history over the past decade. EHR use is pervasive throughout the organization from nurses and physicians to physical therapists and social workers, a fact that is evident when entering York Hospital’s patient care areas. Flat-panel monitors display Cerner iAware integrated data. Vital signs, laboratory results and hundreds of pieces of patient data are compiled in dashboard views that paint a picture of total situation awareness of a patient’s condition for the clinician. Building on a long history of partnership, Cerner approached WellSpan with the prospect of being the first hospital in the nation to implement Cerner Care Aware Smart Pump Auto Programming and Infusion Management, a technology that combines the safety features of an automatically programmed infusion pump with software that provides clinical visibility to real-time infusion

Site Visit data. Cerner shared its vision of an EHR able to display infusion data (medication, dose and rate), as well as hourly volume infused and a continuous volume countdown based on information received from the infusion device. Collected at a single location, pump data combined with patient data from other sources would enable WellSpan to realize unprecedented clinical productivity, effectiveness and patient safety improvements. “When Cerner asked if we wanted to alpha partner on Infusion Management, we knew it was the perfect project,” recalled Ms. O’ Shea. Technically, the project required substantial engineering resources. Cerner developed a data-exchange platform called CareAware iBus, to enable twoway communication between devices (pumps, monitors, etc) and the EHR. WellSpan’s infusion pumps would need to send dosage, rate and volume information into the EHR. WellSpan selected Hospira’s Symbiq Infusion System with Hospira MedNet safety software to do the job. “Hospira stood out as the company most ready to work with Cerner to make the pump and the electronic health record work together so that our staff could focus their time on caring for patients,” recounted Dr. Baker. Together, the solution suppliers created a system in which data flow from Cerner Millennium to CareAware iBus to the Hospira MedNet safety software to the Symbiq pump, and vice versa. Work began in December 2009 when CareAware Infusion Management was initiated in a 10-bed medical-surgical intensive care unit (ICU) at York Hospital. In January 2010, Symbiq pumps were launched. The following July, WellSpan expanded its infusion clinical integration with auto-documentation and smart pump auto-programming.
ciates the pump to the patient and the ordered drug within Cerner Millennium so the nurse is able to verify the “Sixth Right,” the right rate of infusion. An alert is displayed if one or more parameters do not match or if the dose or rate falls outside the established limits in the Hospira MedNet drug library. The nurse must correct the error and verify the infusion pump settings before the infusion is initiated. The benefit to nurses of CareAware Smart Pump Auto Programming and Infusion Management were immediately obvious. The number of steps required for programming the smart pump fell from more than 27 down to just seven with auto-programming. All infusion data are sent directly to the EHR, improving accuracy of documentation and allowing the nurse more time with the patient. “The system captures changes automatically so you don’t have to jump into the computer to constantly enter rates and titrations. It is all done for you to streamline the documentation process,” Ms. Muller said.
Pharmacy Impact Yet the benefits of Infusion Management are not limited to the nursing unit. For pharmacy, Infusion Management presents a never-before-possible path to operational efficiency, waste reduction and improved safety. Advanced data integration enables a real-time Phar-

Point-of-Care Impact Sharon Muller, RN, MSN, York’s coordinator of nursing clinical informatics, summarized the point-of-care benefit of smart pump auto-programming. “Taking the human element out of programming the infusion pump greatly reduces the opportunity for error,” she explained. “The safeguards built into Infusion Management coupled with the safety limits built into the pump software allow us to avoid programming [mistakes such as] double-tap errors. The workflow begins with scan, scan, scan [Table].” Bar-code scanning provides a quick and easy user interface to the Infusion Management system. Via the hospital’s wireless network, bedside scanning confirms the “Five Rights” of medication administration—making sure that the right patient is receiving the right dose of the right medication at the right time and by the right route of administration. The scanning process also asso-
macy Infusion Management Dashboard View of all scheduled continuous and titratable medications currently infusing across the facility. Pharmacy technicians responsible for the ongoing preparation of these products monitor the dashboard and, based on the information provided, prioritize preparation based on the time remaining for the current infusion, the patient acuity based on location (i.e., ICU vs. general medical-surgical unit), or even the medication itself (i.e., admix all midazolam infusions due in next 60 minutes). As a result, pharmacy is no longer dependent on nurse requests to begin preparing infusions and scheduled meds are delivered in smaller batches to the units. “With the real-time view of all of the infusions’ status provided by Infusion Management, the pharmacy can dispense medications to the unit on a just-in-time basis prior to the current infusion bag’s completion so that the patient’s therapy is uninterrupted,” Mr. Gerhart explained. “We also avoid the stockpiling of medications on the unit that end up being returned to the pharmacy, thus reducing our crediting workload and waste as well as decreasing that opportunity for error resulting from the increased availability of medications.” To eliminate the need for nurses to continually call the pharmacy for status updates on requested IVs, the pharmacy took a page from the FedEx playbook.

EHR, electronic health record
Leveraging Cerner’s Workflow Monitor tool, pharmacy staff scan the infusion’s label throughout the preparation process to provide nurses with real-time updates on the preparation status via the Infusion Management Unit View Gadget. Progress on the infusions’ status can be viewed remotely by nurses as pharmacy staff scan the label through the tool from “Ready to Compound” to “Ready for Check” to “Checked” to “Ready for Delivery” to “En Route” and finally to “Delivered,” which will signal the nurse to look for the bag on the unit. In the future, bar codes added to the refrigerators will further add to the supply chain data trail. In the event a medication is dispensed to the wrong location, it will be quickly recognized upon investigation.
Measure of Success Across the board, clinicians consider the positive impact on patient safety to be the most important outcome of autoprogramming. “When patients see the technology we’ve helped develop, they know we are doing everything we can to keep them safe and deliver the best possible care,” said Ms. O’Shea. To date, WellSpan has documented more than 300 near-miss medication errors that have been prevented by the auto-programming system. Additionally, alerts prevent infusions that exceed the drug library limits set on the smart pumps. It is estimated that smart pump safety software prevents an average of 30 potential adverse drug events in each two-month period at an estimated cost savings of more than $260,000 and potential savings of more than $1.5 million per year. WellSpan also has documented significant improvements in caregiver efficiency. The reduction of infusion steps from more than 20 to just seven with auto-programming results in a 27% reduction in time to start and document each new infusion. Yet, the greatest time savings relates to the documentation of code blue cardiac arrest situations. Previously, retrospective charting took up to 120 minutes to recount from memory and handwritten notes the events and chronology of the code. Today, with one click, the CareAware system pulls information directly from the infusion pump during the code and back-associates all the information with physiologic and hemodynamic parameters from cardiac monitors. The nurse reviews the data and signs off on it. The synchronized data are recorded automatically in Infusion Management, reducing post-code documentation time to just five minutes. Although the frequency of IV documentation increased from once every eight hours to once hourly, there was an 87% reduction in time for a single

Medical Center Decentralizes With Omnicell Technology T
he University of Chicago Medical Center (UCMC) has embarked on an aggressive pharmacy technology rollout that, beginning in January 2012, promises to reduce inventory costs, nursing and pharmacy staff hours and speed medication delivery to patients, according to the team tasked with coordinating the program. The major goal of the technology rollout is to help the hospital decentralize pharmaceuticals distribution, coinciding with a multihospital expansion into a newly constructed third building on campus. The medication network will fully integrate with UCMC’s Epic electronic medical records (EMR) system by the end of a two-year rollout; the network will extend from new carousels in central pharmacies in two of the buildings to 94 automated dispensing cabinets (ADCs) at points of service for 594 beds, according to Dave Hicks, RPh, MBA, UCMC’s vice president and chief pharmacy officer. According to Mr. Hicks, the anticipated gains from implementing certain elements of the Omnicell G4 platform include: • Perpetual inventory management enabled by the carousels. These will improve inventory turns from 19 currently to 25 by fall 2012 in Comer Children’s Hospital and by spring 2013 in the new building for the Bernard A. Mitchell Hospital. “We will earn a one-time savings of $400,000 and ongoing annual savings of $60,000,” Mr. Hicks said. “It will also give us the capability to post online catalogues for our drug clinics that want to reorder supplies. It will list what they can obtain, and will bill it automatically to their cost centers.” • A 90% reduction in missing doses. “One of our overriding concerns was the large number of medication handoffs in our particular implementation of 24-hour cart fill, which created missing medications,” Mr. Hicks said. “The automated system will have fewer handoffs and higher integrity.” • Faster fills of routine first doses of new medication orders. Using Epic, pharmacists can verify a physician order in nine minutes on average. Because 90% of medications are available in an ADC on the patient unit, they are available for a nurse to administer as soon as a pharmacist completes verification in Epic. This is much quicker than the current 60-minute average cycle at UCMC. It takes that long, Mr. Hicks explained, because “in our current hybrid envi-

ronment, a label prints for manual filling or goes to the robot for automated filling. Manual picks are then checked and sent via pneumatic tubes or hand-delivered on hourly rounds. There are then one or two handoffs and potential waiting time for that medication on the nursing unit before the nurse knows it is there for her to administer.” • $10 million savings in nursing and pharmacy labor costs over 10 years. UCMC undertook an extensive business process-mapping project to document workflow savings. Primarily due to two Omnicell components—SinglePointe software to help track items not typically stored in cabinets (such as IV solutions usually kept on hooks or countertops) and the OmniDispenser module for controlled substances—the medical center projects a savings of 10% of its $100 million in nursing and pharmacy labor costs to distribute medications over the next decade. “This translates into about 22,000 hours
of nursing time per year that we can reallocate to other aspects of patient care,” Mr. Hicks said.
4.1 Million Doses Per Year UCMC has dispensed about 4.1 million doses per year for the past few years, and this level is expected to remain constant, noted Mr. Hicks, who believes the G4 platform will help the medical center avoid staff expansion, except for some new technicians. UCMC committed to five elements of the Omnicell G4 platform after two years of due diligence from a charter multidisciplinary team that included pharmacists, nurses, information technology, the facilities and engineering departments, the chief financial officer, the chief nursing officer and Mr. Hicks. “Our team developed a vision, then we went to the marketplace to see who could meet that [vision],” Mr. Hicks said. Physicians were updated on matters of medication safety and security and staff workflows. When asked about the technology’s potential
impact on patient safety and outcomes, Mr. Hicks said, “We can’t quantify we can reduce length of stay. But anytime we can improve the speed [at which] medications are administered, we improve opportunities for patients to get better faster.” UCMC’s technology users also were given the chance to sample systems from three vendors, including Omnicell, at a vendor fair held on the medical center campus. Most important to Mr. Hicks was the SinglePointe software, which he said provides a method for integrating “exception” products that are not typically stored in a particular nursing unit, such as IV solutions. “The software dedicates a bin for a specific solution for a specific patient, so the nurse on the next shift just goes to the bin and knows it is there,” he said. OmniDispenser, which dispenses controlled substances like a vending machine, was another differentiator for Mr. Hicks. “If a nurse needs one dose of morphine, she gets one dose only. So there’s no need to do a count to verify

Automation and there’s less potential for diversion,” he explained. “We’ll no longer need nurses to count controlled substances at the end of their shifts.” Moreover, the Omnicell Pharmacy Medication Management Carousels with WorkflowRx software will occupy central pharmacies in two buildings on campus, updating the current shelfstorage process; 94 OmniRx G4 Automated Medication Dispensing Cabinets will be dispersed throughout nursing floors (75 of them to be equipped with OmniDispenser because there is less need for them in ambulatory areas); and AnywhereRN allows nurses to review and select medication orders needed from the cabinet remotely. Another priority for UCMC is to have a single, integrated database—one goto place to maintain all its medication files more expediently and accurately, rather than have to separately update its formulary and drug files in distinct cabinets, narcotics and data systems— and the G4 platform provides this capability, said Mr. Hicks. The new era at UCMC begins to go live this coming January, when carousels start up in one central pharmacy. By July 2012, the same building will see replacement of all of its current cabinets with the OmniRx cabinets. By January 2013, carousels will go live in the new building, with the rest of the new cabinets to follow. According to Robert Adamson, PharmD, corporate vice president-clinical services, Saint Barnabas Health Care System, West Orange, N.J., a pri-
mary benefit of decentralized distribution is more time spent by pharmacists to use their cognitive abilities and less time on distributive functions. If pharmacists release medications from the ADC right on the floor, they are readily available to interact with patients and have face-to-face access with care providers, increasing collaboration, he noted. To measure how that workflow strategy improves customer satisfaction, Dr. Adamson uses metrics such as turnaround time, medication errors per High alert 7.625x9.375_F:Layout 1 10,000 doses and Hospital Consumer
Assessment of Healthcare Providers and Systems (HCAHPS) scores, which he says are often “medication-related and directly tie to the pharmacist– patient interaction.” Dr. Adamson cited what he looks for when selecting a vendor: reliability, durability, security (decreasing medication access to care providers until a pharmacist has verified an order) and the vendor’s interface with existing systems. “Many hospitals will charge for a medication when that medication 5/22/09 9:47 AM Page 1 is removed from the ADC. This needs

to interface with our billing system and drop the charge for the medication,” he said. As for hospitals seeking integration with EMR systems, “there are vendors that have medical records that can be for both outpatient and inpatient,” observed Dr. Adamson. “The challenge is [to find] resources to convert existing systems to EMR. They do exist, but [they require] huge commitments in time and money to implement.” —Al Heller

Groups Call for Safer Smart-Pump Drug Libraries E
ach year, thousands of medication errors cause patient injury and death, and medications that are administered intravenously have the highest risk for errors. According to the FDA, more than 56,000 adverse incidents from programmable IV infusion devices, commonly called “smart pumps,” were reported from 2005 to 2009. Experts say the total number of incidents, reported and unreported, is likely closer to 400,000. In response to safety concerns, the Association for the Advancement of Medical Instrumentation (AAMI) announced in a press release last month that it is partnering with the American Society of Health-System Pharmacists (ASHP) and the FDA to reach out to the health care community for help developing guidelines and recommendations for the management of programmable pumps. “What we want to do is standardize the drug libraries to better protect our patients,” said Karl Gumpper, RPh, of ASHP and the group leader heading the collaborative effort. “We also want to encourage hospitals and health systems to use programmable devices that interface with their information systems and include the standardized libraries with dosing limits and clinical advisories.”
How Smart Pumps Work Smart pumps include software that allows a hospital to create a library of medications that provides dosing guidelines by establishing drug concentrations and hospital-defined upper and lower dosing limits. Various alerts and clinical advisories also can be built into the software to prevent errors. These notifications are designed to prevent users from programming in an overdose by signaling when the dose they’ve selected is out of the predetermined range for the medication. The user may easily override a “soft” stop, and the medication can be infused without changing the pump settings. But a “hard” stop won’t allow the user to administer the infusion unless the pump is reprogrammed within the acceptable range. The pumps can be tailored for patient weight and specific patient groups, such as those in cardiac, pediatric or intensive care units. The use of smart pumps is increasing. In 2010, 65% of nonfederal U.S. hospitals reported using smart pumps, up from 32% in 2005, according to the 2010 ASHP national survey of pharmacy practice in hospital settings.
What Can Go Wrong? “National standards for IV medication use are desperately needed because there are many possibilities for error
in infusion-device programming,” said Mark Sullivan, PharmD, director of pharmacy operations at Vanderbilt University Hospital in Nashville, Tenn. Vanderbilt was one of the first hospitals to implement smart pumps on a widespread basis. Dr. Sullivan said that the wrong medication with a similar sounding name may be administered, a medication may be accidentally programmed in micrograms per kilogram per minute instead of micrograms per minute, or an additional zero may result in a 10-fold overdose. “In many instances, pressing a single wrong key when programming delivery can harm a patient,” he stressed. To illustrate, here are several examples of errors involving smart infusion pump technology that occurred in Pennsylvania medical facilities. (PA-PSRS Patient Safety Advisory-Vol. 4, December 2007): Failure to use standardized concentrations of high-alert medications. Hospital policy dictates the standard Levophed solution is 4 mg/250 mL. The nurse programmed the smart pump incorrectly by entering the standard solution of 4 mg/500 mL. Wrong drug administered. Staff found Levophed running on a smart pump programmed for neosynephrine infusion
at 200 mcg/min. The Levophed solution was not scanned prior to administration and the wrong medication was administered. The patient had orders for both vasopressors. Wrong-rate medication error with no upper dosage alert. A nurse at a Pennsylvania hospital incorrectly programmed a smart pump to run a patient’s total parenteral nutrition at 625 mL/ hr, instead of 62.5 mL/hr for 24 hours. Unfortunately, there was no preprogrammed dose limit in the device’s drug library to alert the nurse to the error. The mistake was discovered 90 minutes later, when the patient became short of breath. Although he was treated appropriately for elevated potassium and glucose, the patient coded and died three hours later.
The Ideal: An Integrated System Creating the smart infusion pump system on a wireless network helps avert such errors. A wireless system allows the pumps to download drug library updates, and to be integrated with computerized prescriber order entry devices, bar codeassisted medication administration and electronic medication administration records. Another advantage of the system is that it provides a large amount of data

Tips: Analyze, Standardize and Do Your Homework
W
hat should be done to improve the technology? Matt Grissinger, RPh, who handles technology-related safety issues at the Institute for Safe Medication Practices (ISMP), offers these suggestions: • Do your homework before buying and implementing smart pumps. What drugs will you include in the library? Will you use different libraries for different patient groups? • Use the team approach. You have to get physicians, nurses, pharmacists and your IT people on board. Make sure everyone is properly trained. • Implement a wireless system. It will reduce errors and make it easier to update the pumps. • Make sure the pumps are automatically set to library mode when they’re turned on. It sounds like a small thing, but it decreases the chance that users will opt-out of using the library. • Standardize the concentrations. For example, you probably don’t need eight concentrations in your drug library; get it down to two or three. • Standardize your data terminology: dose, volume, unit of measure, bolus, loading dose, etc. • Analyze your data. Consider what drugs or alerts are most frequently overriden and make adjustments when needed. • Get user feedback. If nurses are employing “workarounds” to get out of using the library, find out why. Maybe it’s because it’s taking them too long to program the pump. If so, make it easier. —D.H.
that can be used to evaluate smart pump use. Data collection can include the number of infusions programmed into the drug library, soft stop overrides and how often an alert resulted in reprogramming of an infusion. Clearly, a completely integrated system is ideal. No facility is closer to reaching that goal than Lancaster General Hospital in Lancaster, Pa. “Ninety percent of the time it works really well,” said Tina M. Suess, BSN, RN, who has worked with Lancaster’s interoperable system for several years. “Sometimes it can be as simple as ‘plug and play,’ but there are a lot of factors involved, including the nurses, the pharmacy and the strength of the wireless infrastructure.” Ms. Suess said the biggest challenge initially was to convince nurses to use the system. Early on, they were using the drug library only 40% of the time; currently, that figure has risen to nearly 70%. Lancaster’s system may not be perfect, but it’s working. “You don’t realize how often manual pumps are programmed incorrectly because those errors oftentimes go under the radar,” said Amanda Prusch, PharmD, BCPS, Lancaster’s medication safety specialist who oversees the drug libraries. “But we’ve definitely seen a decrease in errors with integration.” For instance, interoperability expanded the role of the pharmacist to include checking infusion rates of IV medications, which resulted in a 32% reduction in monthly IV heparin errors reported from the telemetry and medical-surgical patient care areas (Am J Health Syst Pharm 2011;68:835-842). For now, Lancaster is one of a handful of hospitals in the country with an interoperable medication administration system. But that’s slowly changing. “We’ve made great strides over the past 10 years. But it will take another decade for one-fourth of the market to have achieved true interoperability,” Dr. Sullivan said. “We need to continue to beat the drum to ask vendors to make these systems talk and work better together.” He issued a call to action in an editorial that appeared in AJHP last year: “Health-system pharmacists must play a leadership role in helping achieve the full potential of infusion devices to improve patient safety.” —Dana Hawkins-Simons

document intake session. Documenting hourly intake has provided greater clinical insight into a patient’s status across the care team without additional nursing time expenditure. Time was cut by 50% for titrations and the time necessary to document them. Although the difference is only 13 to 16 seconds per titration, the savings accumulates to more than 1,300 nursing-hours saved per year. The success of auto-programming at York Hospital is partly the result of nurses’ consistently high rate of compliance with system safeguards. After adjusting for select regimens that commonly require system overrides (sodium chloride, blood, plasma, and platelets), compliance was 78% in October and 79% in November. Likewise, average compliance with the Hospira MedNet safety software was 94%. Yet another success factor was the collaboration between WellSpan, Cerner and Hospira. In May 2011, the three organizations were given a Way-Paver Award at the unSUMMIT for Bedside Barcoding in acknowledgment of the years of joint development required to overcome technical limitations and satisfy workflow needs of WellSpan nurses, pharmacists and physicians. Together, the partners created an advanced infusion management system that accomplishes—true to Dr. Baker’s philosophy— what was not possible with paper. Ms. O’Shea beamed with all due pride, “I think we’ve forged new ground. It’s the wave of the future.” Ms. Kelly is an independent marketing consultant serving health care information technology vendors. Ms. Kelly and her partner, Mark Neuenschwander, organize the annual unSUMMIT for Bedside Barcoding educational forum. For more information on the 2011 summit, visit www.unsummit.com.

Q&A breaking down those silos. To do that there’s all kinds of data aggregation that needs to occur. One of the big buzzes there is how to aggregate and then disseminate all of that medical information in a meaningful way. It certainly will be one of the focuses of the AMIA meeting.
Q
: How can pharmacists best use social media? A: I’m a very social guy and so I do a lot of social media and share my opinions and profession publicly, and I’m not afraid to do that. That’s typically not what pharmacists do, and that’s OK. The best practices for doing this are yet to emerge, but I think the sharing of scientific knowledge is necessary. Everybody does their own thing, and if everybody made that more public and more accessible, then I think we would all grow by having that out there in the clouds. For example, as I go through my daily routine and I come across clinical and scientific instances that are relevant in my practice, it takes just a moment out of my day—a few clicks or taps—to make that public. I think we need more of that. I can follow infectious disease experts and understand what they’re learning and doing when I need to, and other pharmacists can follow my informatics streams so they can learn. To me, that’s the true potential for social media, beyond the personal stuff. That’s why I use it. I follow some amazing people, who point me to just incredible stuff and I feel like I’ve grown tremendously with that.
What is your current take on whether pharmacy as a profession is doing enough to promote a “just culture” so that pharmacists feel safe coming forward if they make an error? A: I am disappointed that ASHP did not consider at least providing some support for Eric Cropp, but am aghast that they failed to perceive and deal with the larger issue of permitting a legal precedent that leaves pharmacy as the only profession for which committing a medication error is now a felony offense. Permitting Mr. Cropp to plead guilty to a felony charge
because he lacked the resources to fight the case has placed the entire profession at legal risk. While ASHP was missing in action on this issue, ISMP [the Institute for Safe Medication Practices] recently announced an upcoming webinar focusing on understanding the “second victims” of medication errors—the health care professionals who make the errors (www.ismp.org). This effort is very positive for promoting a just culture and is a step in the right direction.
Next Month Pro/Con: BCMA Bedside bar coding has been touted for years as a powerful tool for reducing medication errors. But more than 50% of U.S. hospitals have not yet embraced the technology. Two informatics specialists face off on whether bar coding is mature enough to warrant more widespread adoption.

Q
: What does the future hold for clinical informatics in pharmacy? A: The current laws and regulations around pharmacists needing to verify every single medication order will need to be re-examined. In an era where technology can review orders and check them for appropriateness as well, does the pharmacist need to check every order or can that be offloaded in some technological way? That’s a game-changer: Can systems check and monitor drug therapy as good as or better than today’s pharmacists, the standard of care? I don’t know the answer to that but I think that’s where things are going. People will continually challenge me on that, and I think that’s great, but I also think that the volume of what pharmacists verify today is huge. There are people studying if clinical decision support can match the quality and safety of pharmacists’ verification; it’s a positive thing that will raise the [level] of all pharmacists to do more things at the patient bedside.
Q
: You had criticized ASHP in a recent blog post for not stepping forward to defend pharmacist Eric Cropp, jailed for a medication error.

medication errors were recorded for 137 (30.3%) of them. Pharmacists and pharmacy students gathered the data for the 10-hour shifts when pharmacists were present; resident physicians collected the data when pharmacists were absent. Antibiotics were most often subject to error, followed by pain medications, cardiac medications and gastrointestinal medications and antiemetics. Typical errors included wrong dose (either too little or too much), medications given or not given without regard to order status; wrong administration technique, and so on (Table 1). Pharmacist interventions consisted mainly of dosage corrections, which the pharmacists carried out themselves, and alternative suggestions, which were accepted by the physicians 91% of the time. Amy Ernst, MD, professor in the Department of Emergency Medicine and lead author of the study, noted that pharmacist intervention was simply a matter of communicating knowledge. “For example, we [physicians] use so many antibiotics, and the pharmacist will come up and say, ‘That’s not the best choice for that particular infection,’ and suggest something better.”
Go Where the Need Is The University of New Mexico study is the first to evaluate the impact of pharmacist intervention in the ED with respect to patient disposition. Pharmacist intervention had a particularly strong effect on patients in the intensive care unit (ICU), where there were 55 patients with medication errors. Of these, 51 had errors while no pharmacist was on-site (Table 2). “Overall, there will be more errors in the ICU,” said Dr. Ernst. “The cases are more complicated, the patients have more done to them, and there are more medications.” And there’s more potential for patient harm, Dr. Ernst stressed. Although most of the medication errors in the study did not cause harm or require intervention, “four patients experienced errors that required either intervention or prolonged hospitalization,” she noted. “All of these errors occurred when pharmacists were absent, and it is possible that the presence of an on-site pharmacist could have helped avoid these [mishaps].” In those four patients, the drug errors included a patient who was given albuterol/ipratropium nebulizers too frequently and developed supraventricular tachycardia; a patient given atropine with a known allergy who developed hallucinations; dopamine and norepinephrine started at the wrong rate of infusion; and epinephrine administered

via an IV instead of intramuscularly. All of the errors resulted in ED patients being admitted to the hospital; two of the patients required ICU care. These results “tell us about risk,” said Kyle Weant, PharmD, BCPS, clinical pharmacy specialist in emergency medicine/critical care at University of Kentucky HealthCare in Lexington. “It answers the question of where you put your time and what populations you should focus on if you’re an ED pharmacist. If you have limited pharmacy resources, it tells you where you’re going to get the most bang for your buck.” Daniel P. Hays, PharmD, BCPS, FASHP, clinical pharmacist in the Departments of Pharmacy and Emergency Medicine at the University of Arizona Health Network, Phoenix, agreed. “Of all the areas where clinical pharmacists can make an impact, the ED is one of the places we should go first. Emergency rooms don’t have the
safety checks that are in place in other areas of the hospital, where doctors and nurses run checks,” he said. “We can provide that layer of safety and care in high-risk situations.” That the vast majority of physicians in the study accepted the pharmacists’ suggestions speaks to how far ED pharmacy has come, Dr. Hays said. “Once physicians know who you are and what you can do for them,” he noted, pharmacist recommendations are followed and have a direct impact on patient care. In a crisis such as resuscitation, Dr. Weant noted, that kind of trust can be a matter of life and death. “Things happen so quickly, you don’t have time to debate the literature,” he said. “You just have to trust that what the individual beside you says is right. “Even when you look at the authorship of the study [where a physician is the lead author], that helps you see that there is a wonderful collaboration,”
Dr. Weant added, noting that the study itself represents a significant shift in the literature. “If you look back on older studies, one of the challenges for pharmacists in the ED was whether they’d even be accepted.”
Study Limitations Dr. Ernst and her colleagues note the study’s limitations in their paper, namely that the study involved only one center and that it was part prospective, part retrospective. But, according to Dr. Weant, those limitations are a spinoff of the study’s strengths. “It is very challenging in a busy level 1trauma center to do a prospective study and identify and prevent all the errors that may be occurring simultaneously; it is far easier to sit in a quiet room in medical records and identify errors that may have occurred on a retrospective basis,” he explained. “The fact that the researchers were able to identify a difference given this inherent disadvantage is a tribute to both their program and the impact of their services. As most hospitals aren’t busy level 1 trauma centers, this bodes well for other institutions trying to replicate this data on a prospective basis and improve overall patient care and safety.”
Building a Case The University of New Mexico study bolsters the case for integrating pharmacists into the emergency care team. An earlier study at the University of Rochester Medical Center in New York, co-authored by Dr. Hays, found that a pharmacist’s presence can reduce the time it takes to get patients with ST-elevation myocardial infarction from the ED to the cardiac catheterization laboratory (J Emerg Med 2010 Aug 31 [Epub ahead of print]). In a 2010 study led by Dr. Weant at the University of Kentucky (Am J Health Syst Pharm 2010;67:1851-1855), researchers found that pharmacy personnel caught the lion’s share of medical errors compared with other health care workers (94.5% vs. 5.7%, P<0.001). Moreover, pharmacists’ interventions prevented 79.6% of drug errors from reaching patients. —Terri D’Arrigo

As Maxwell states, “Successful people make right decisions early and manage those decisions daily.” What are those pivotal decisions that you have made or perhaps need to make now? If you decide these and rehearse them, if the time comes to use them, those decisions become the automatic response. And these decisions represent part of your character—as an individual, as a leader and as a member of your social network. The greatest power in life comes from your ability to choose. Your choices define who you are and make a statement to those around you. The key is to be true to yourself. Legendary basketball coach John Wooden said, “There is a choice you have to make in everything you do. So keep in mind that in the end, the choices you make, make you.” The way I “vet” my choices is by creating a framework composed of my morals and beliefs and use it as a decisionmaking matrix. The following are the beliefs and values I choose to measure my choices against: • Always support your people • Don’t compromise your values • Treat everyone with respect • Be a straight shooter • Be honest and fair • Be highly committed • Work hard • Do the right thing • Have others’ interests at heart • Operate with humility • Keep an even-keel disposition • Maintain a positive attitude • View challenges as a growing experience • See the big picture, but focus down to the most minute detail • Be trustworthy • Have strong convictions • Be caring toward others • Hold self and others accountable • Believe in others • Hold high expectations of self, others • Have a willingness to work with others • Maintain a willingness to admit mistakes, regroup and move forward • Have broad interests What’s on your list?

Workflow
Leveraging 340B Savings To Re-engineer Pharmacy Optimized billing software gets Virginia Hospital on road to more patient-focused care
W
hen University of Virginia (UVA) Health System director of pharmacy Gary Johnson, PharmD, identified extra opportunities that enabled his hospital to save an additional $1 million in outpatient medication costs over the course of just six months through its participation in the federal 340B Drug Pricing Program—which limits the cost of covered outpatient drugs to certain entities, including qualified hospitals—he knew just what to do with the extra cash. Dr. Johnson and his team plowed the savings into a comprehensive re-engineering of the hospital’s inpatient pharmacy system—prescribing, dispensing, administration and monitoring. Working with pharmacy automation provider Talyst, which facilitated UVA’s ability to maximize its 340B savings through optimized billing software, the UVA pharmacy went from an outdated, patchwork-quilt set of silos with irregular monitoring to a virtually seamless, integrated, carefully overseen system. As a result, the hospital decreased inventory carrying costs by $500,000, reduced medication dispensing errors by 76% and administration errors by 40%,
improved order turnaround time by 92%, and decreased drug costs by $6 million (in addition to the 340B savings). How were these dramatic results achieved? Through fundamental changes to all of the core components of pharmacy operations (Table). The strategies aren’t just about switching from name brands to generics, Dr. Johnson stressed—that’s done automatically. “The real value of the pharmacist is to suggest an alternative drug, which may be less expensive but equally effective, or a drug that is more effective and gets the patient discharged and back home more quickly. A very rich environment for these sorts of interventions is found in the critical care units.” Pharmacists often help physicians with appropriate prescribing of antibiotics, Dr. Johnson said. “This is a very large and very expensive drug class, which is often prescribed inappropriately. Another opportunity to better manage medications was found with the drugs used to treat hemophilia patients and/or patients who require very expensive medications for blood disorders. These drugs are genetically engineered,
recombinant and can cost up to $75,000 per treatment regimen.” Overall, this more rational medication use model has led to a $7 million decrease in drug expenditures (including the 340B savings), putting that expense at 12% below budget for the fiscal year.
Key Outcomes Medication errors: 76% Inventory carrying costs: $500,000
Order turnaround time: 92% The pharmacy received an Innovation Award from Virginia Gov. Bob McDonnell in August—an honor designed to recognize ideas that produce efficiencies or cost savings. “But this really goes beyond saving money,” Dr. Johnson said. “It’s about quality, reduction in errors and improvements in care.”
Praise From a Fellow Pharmacy Director Tom Van Hassel, RPh, MPA, director of pharmacy at Yuma Regional Medical Center in Yuma, Ariz., praised Dr. John-
son for “demonstrating exactly what pharmacy technology is supposed to be used for.” Mr. Van Hassel’s own hospital has long been leading the way in pharmacy automation. “This technology is designed to allow your staff to get involved in clinical care by allowing the mundane duties of the pharmacy to be done virtually error-free, and they’re [the University of Virginia Health System] really making the most of that.” Why aren’t more hospitals jumping on board? “Technology has a high startup cost,” Mr. Van Hassel said. “And pharmacy directors on the whole don’t have a lot of experience in dealing for capital dollars—not like radiology and labs. We’ve really only been involved in technology for about 10 years.” Dr. Johnson isn’t about to sit around polishing his Innovation Award. He’s got plans for the 340B savings that continue to come in. “Now, I want to go back and re-engineer the outpatient pharmacy environment,” he said. “I think we have a similar level of improvement and savings to achieve there.” —Gina Shaw
Table. Impact of Re-engineering on Pharmacy Operations Before
After
Prescribing
UVA had a physician order-entry system for medication prescription, but the system was dated and had limited functionality, giving prescribing physicians incomplete information.
Medications are prescribed within a new EMR that is fully integrated with patient-specific data systems, such as laboratory and radiology, as well as with ambulatory care.
Dispensing
Medications were dispensed through a centralized system that refilled medication carts in the pharmacy, and then exchanged those medication carts on the nursing units, every 24 hours. The process included an awkward combination of both robotic and manual systems for dispensing medications that was performed by both pharmacists and technicians.
Medication dispensing is now fully automated, driven by the bar codes found on every medication. The process begins by importing the daily delivery of medications from the distributor into perpetual inventory software—a function that decreased inventory levels from 11 to five days and generated a $500,000 inventory reduction. Medications are stored in four inventory management carousels that, in conjunction with the perpetual inventory software, ensure that each drug is scanned and then placed in a precise, software-determined storage location, as opposed to an alphabetized system. Automated dispensing devices, similar to ATM machines, now stand on each nursing unit and have replaced the old medication cart. Containing up to 250 different medications, the devices interface with the new EMR and the pharmacy’s perpetual inventory system, and allow nurses to retrieve all medications with active orders. Every 12 hours, the devices transmit replenishment data to the perpetual inventory software, which then causes the carousels to turn and dispense the required medications to replenish the devices. Bar-code functionality ensures that the correct medication is retrieved from the carousel to replenish each dispensing device—a step that’s largely responsible for the 76% decrease in dispensing errors.
Administration
Because patient-specific medications were only updated every 24 hours—with the exchange of the medication carts—the system was susceptible to errors, allowing discontinued medications to remain available for dispensing and newly prescribed medications to languish unavailable in the pharmacy.
Bar-code medication charting requires nurses to scan both the patient’s wristband, as the patient identifier, and the drug being given. The software then searches the EMR to ensure the patient has an active order for this medication. If not, the system will alert the nurse that an incorrect medication is about to be administered. Not only has it decreased medication administration errors by 40%, the new system also gives nurses immediate access to 90% of needed medications within five minutes of order entry—as opposed to the average processing time of 60 minutes required under the old system.
Monitoring
Saddled with dated information technology, UVA’s medication monitoring was rudimentary at best, with pharmacists monitoring remotely from the hospital’s basement—a location that hampered their integration into the patient care team.
Because automation has permitted so many more pharmacy tasks to be performed by technicians, a number of pharmacists have been reassigned to the nursing units. That doesn’t just make for happier pharmacists—turnover dropped from 23% to 8%—but it also leads to smarter prescribing. Pharmacists work closely with prescribing physicians, making recommendations for more effective and/or less expensive medications.

Wicked Change
Wicked Problems and the Challenge of Constant Change At the center of your being, you have the answers. You know who you are, and you know what you want. —Lao Tzu, Taoist philosopher
H
ealth care organizations face enormous challenges. Costs are too high and there is too little associated value. Indeed, the United States spends 16% of its gross domestic product on health care—well over $6,000 per person, which is more than double the amount spent by most other free-market economies. Yet, outcomes in this country are in most cases no better and in many cases substantially worse.1 The transformational change in health care that is needed to meet this huge challenge has become one of our most critical macroeconomic issues. In fact, its complexities are so huge that they warrant characterization as “a wicked problem,” to borrow a phrase from the social sciences: that is, a problem whose solution is highly complex, requiring a great number of people to change their mindsets in order to foster a new way forward. After decades of discussion, it is seriously time to take action. Although the current economic crisis looms large and it is tempting to think we’ll eventually return to normal, the high-stakes urgency facing health care and the economy as a whole suggest that “normal” will never be the same again. This is not business as usual. In 2001, the Institute of Medicine (IOM) stated that “between the care we have, and the care we could have, this is not just a [quality] gap but a chasm.”2 In the intervening years, the gap has not changed substantially, in part because we tried to leap the chasm in short hops. The issues of safety, effectiveness, patientcenteredness, timeliness, efficiency and equity that IOM identified still serve as markers for what we need to change in transforming our practices—broadly for health care overall, and more specifically for our pharmacy. The recent American Society of Health-System Pharmacists–sponsored Pharmacy Practice Model Initiative (PPMI) highlights the need for pharmacy leaders to rethink, redesign and redeploy our professional resources to focus on the patient and to bring greater value to the patient care process. A host of recommendations resulted,3 but I continue to hear leaders struggling with just how to use the recommendations as tools to bring about change in their own practices. What will enable us—individually and collectively—to deliver care that is safe, effective, patient-centered, timely, efficient and equitable, designed to meet the
IOM challenge of more than a decade ago?2 Where do we focus efforts for the greatest impact? The Institute for Healthcare Improvement (IHI) offers a simple framework for achieving change that is based on three essential elements: will, ideas and execution.4 The will to improve is required at every leadership level. This is what John Kotter calls “a sense of urgency.”5 As leaders, we have to make the status quo sufficiently uncomfortable to create a tension for change that will pull others into the process. We need to cultivate creative thinking and ideas so that we can develop alternatives to the status quo. But we also need to act on those ideas to make the change real and embedded in our daily practice. Most critically, we need strategies for testing and rigorously evaluating our ideas for change. We also need to build small wins of innovation, learning and opportunity, without defaulting to the temptations of either incremental tinkering or the “big bang change” of untested ideas.
Embracing Change On a Daily Basis Transformation and improvement will mean change, and what we learn very quickly is that this shift cannot be realized unless “change making” becomes part of the fabric of every job, every day, in every part of the system. Indeed, that change-making process must function with an alignment of purpose that demands a whole
of care that taps the full expertise and value of every health professional in support of the patient’s health goals. Leaders need to recognize that in the course of developing new competencies, even our most talented professionals may feel insecure or even incompetent as they struggle in early stages of change. As a leader in such cases, you will need empathy and nurturing skills as surely as you will need your strategic and critical thinking skills, because you will need your people’s help and support as never before. And if you are going to prepare your team for that sharing of leadership and accountability for transforming care, you must equip them with the ability to perform in an environment of continuing uncertainty and uncontrollable change. This puts you in the environment of both improvisation and experimentation. The analytical problem solving, crisp decision making and articulation of clear direction that got you where you are can in fact get in the way of future success. Although they will still be an asset at times, the adaptive requirements of operating in a permanent crisis and dealing with wicked problems that have no apparent (i.e., traditionally acceptable) solution will require you to have new leadership practices.6,7 Today’s leaders need to continue to excel at those past best practices while developing the next practices for adaptation. Make no mistake that the patient must be the common barometer for the change value. Tolerance for ambiguity will be increasingly essential as a behavioral characteristic as we experiment to find the next best step forward.
‘As leaders, we have to make the status quo sufficiently uncomfortable to create a tension for change that will pull others into the process.’ new way of thinking and behaving. In a profession of highly skilled and trained individuals who are incredibly smart and very good at what they do in a narrow track, leaders will need to set new expectations for thinking outside the four walls of pharmacy, focusing first on the patient. New competencies and skills must be nurtured and developed to facilitate this shift in thinking. The shift needs to be toward health, not health care, and to a boundaryless, collaborative, team-based model

As we move from the old paradigm for health care delivery to the emerging new paradigm, the disequilibrium that we experience every day is unsettling. Facing the new realities, the stress and distress of change, will demand that leaders orchestrate the conflict, chaos and confusion of the change to minimize disruption. A culture of discussion, dialogue and openness can create both the candor and risk-taking that allow you to establish antennae throughout the organization to identify risk and opportunity, leverage diverse perspectives and distribute leadership to generate solutions and build a culture of interdependence.
Setting a Course of Action For Change So what will get us there? How will your leadership set the course of action for change and how will we develop the skills, knowledge, behaviors and values that are essential to the change? The reality is that the challenges facing our organizations are beyond the capability of anyone’s current expertise. None of us have been here before. Our past experience got us to where we are and the organization that relies solely on senior leadership to resolve the challenges risks colossal failure. This column will focus on change: how to create it and how to cope with it. We will deal with the challenging change issues the

Wicked Change pharmacy leaders—big and small L—face every day, and will provide resources and insights that you can use to strengthen your organization’s change, focus and effectiveness. Guest authors—from inside and outside pharmacy practice—will explore specific challenges and initiatives for change that have provided successful next steps in the right direction, and offer the potential for assessment and adaptation for use in your organization. Each topic (see box) will address issues of will, ideas and execution strategies that can serve to drive dialogue for change within your organization and teams. These human conversations allow people to discover mutual concerns and issues, hopefully creating networks of people who share common perspectives and meaning in the discovery of patterns and opportunities for improvement that
arise from the chaos. We look forward to engaging in the dialogue of change for transformation, and to your involvement with the evolution of the knowledge sharing we anticipate. Please contact me with issues that you struggle with as well as those where you have established a beachhead. Within all of our teams, we have the seeds of solutions, as suggested in the opening quote from philosopher Lao Tzu. Sharing our thinking, experience and results will stimulate the new directions that will reshape the value we
bring to the care team and the patient. We expect to travel well outside the traditional pharmacy comfort zone, and to visit previously unexplored ideas. Welcome to the conversation!

Leadership in Action
RIGHT CHOICES continued from page 38
Instead, they are obsessed with selfimprovement. It’s a lifelong quest. In contrast, there are people who just do the bare minimum to get by. I made a choice as a teenager that I would not be one of those people. Reading leadership books and applying the principles have helped in my character development.
2. Helping people is more important than making them happy. Sometimes our instinct may be to appease someone, rather than to be honest in the interest of correcting or mentoring. As leaders, we often are called on to do the right thing for the sake of the department and the individual. We are called on to conduct counseling sessions that are sometimes unpleasant. These require intestinal fortitude and a long-term outlook. If your
staff knows you have their best interest at heart, counseling sessions become opportunities for growth. Sometimes, we have to move people out of their comfort zones in order to help them to grow. Leaders make choices every day that will make someone, somewhere, unhappy. So having strong convictions and being true to those convictions is paramount. 3. My focus will be on the present. Maxwell asks a question that struck me:
“Do we spend too much time in the junkyard of regret? Are we thinking of what could have been?” Most of us can remember situations and actions that we wish we had handled differently at one time or another. The challenge is to use these experiences to learn and grow and change. We are the sum of our choices, and these choices are reflected in the way we lead. Choose wisely.

were interviewed to assess how much of their time was spent on activities associated with the program, such as checking patients’ intubation or assisting with the placement of central lines. “We made sure we covered all sizes and types of hospitals in terms of specialization. I think there is no question that the results are statistically solid and Michigan is not very different from other states, so the data can be applied to hospitals in different states,” said Dr. Waters. The current hospital reimbursement landscape is increasingly placing the
economic burden of nosocomial infections on the hospital itself; CMS and many commercial insurers no longer pay institutions to treat many HAIs. It has thus become imperative for hospitals to engage in evidence-based prevention methods. Although this type of incentive par-
adigm encourages hospitals to reduce their rates of HAIs through negative reinforcement, the reality is that eliminating every infection may be impossible. “This is an issue with performancebased payment; some hospitals have a much larger number of cases coming in that are at risk for these infections,” Dr. Waters said. “So there’s an argument for some kind of risk adjustment to these rates along with positive incentives for those showing improvements.”

With a new pharmacy-specific approach to immunology, Immunology for Pharmacy prepares pharmacists for practice by providing a complete understanding of the basis of immunology and the consequences of either suppressing or enhancing immune function.
