SUMMARY

EXECUTIVE SUMMARY

The newly completed Cambridge A (CA) tower has implemented several innovative design features, including decentralized nursing unit, family-centered environment, as well as the Interventional Radiology (IR) and surgical department. In order to test the effectiveness of the new design, a systematic post-occupancy evaluation was conducted in the new CA building in comparison with the existing Bell Tower. The POE has two parts: the first part as the inpatient unit POE and the second part as the surgical department and IR in the CA Tower.

PART I: INPATIENT UNIT POE

Over the past decades, healthcare design has gone through rapid changes to react to the transformation towards patient and family-centered healthcare delivery models. For instance, traditional centralized nurse stations have been gradually replaced by decentralized work stations for the hypothesized benefits of more time at the patient bedside, less walking distance, and better patient care. However, debates persist on the impacts of decentralized nursing units on nurses’ communication and coordination, and related patient outcome and their perceptions of care quality. Moreover, there are many variations of decentralized nursing unit typologies, however, few studies have compared the effectiveness of various decentralized nursing unit typologies and identified the key elements and characteristics for an optimal layout that can support both staff efficiency, communication, and better patient experience. This project aims to empirically evaluate the impacts of nursing unit typology through a comparative study in the newly constructed Cambridge A (CA) building and the Bell Hospital at the University of Kansas Hospital. The research is based on a quasi-experimental comparative study. It intends to compare one typology of a decentralized nursing unit (CA5 Intensive Care Unit and CA6 Progressive Care Unit) with another typology of a decentralized nursing unit with similar staffing model and patient acuity level (Bell Unit 63 Intensive Care Unit and Bell Unit 64 Medical Transplant Unit) to evaluate the impacts of the physical environment on nurses’ efficiency, teamwork, hand hygiene compliance, and patient satisfaction. Research methods include visibility analyses, noise and lighting measurements, pedometer readings, behavior mapping and tracking, nurse interviews and questionnaires, and patient satisfaction and outcome analyses. 7


EXECUTIVE SUMMARY: RESULTS

NOISE

The noise levels at CA6 and CA5 were significantly lower than the noise level at Bell 64 and Bell 63 respectively. The new design allowed better control of noise that provided patients and family with a quieter environment. For CA5 and CA6, there were significantly higher noise levels in the nurse team station than noise in the corridor. For the Bell 63 and Bell 64 units, there was no significant difference between noise in the corridor and noise in nurse team station.

The results showed that overall the two units in Cambridge A provided an increase in overall environmental quality and noise reduction, improved patient care, increased care coordination and inter-professional communication, reduced non-value added

sunlight need additional artificial lighting to support reading.

This resulted in increased walking distances, reduced nurse-to-nurse communication, and possible sense of isolation in CA units in comparison to the Bell units.

VISIBILITY

The units in the Bell hospital have higher visibility and accessibility compared to the units in the Cambridge hospital. Among the four units, Bell 63 has the highest visibility and accessibility compared to the other three units, while CA5 has the lowest visibility and accessibility among them. Central sections in CA units suffer from low visibility and accessibility.

PATIENT ROOM POE

Based on the Center for Healthcare Design standardized patient room POE toolkit,

PATIENT SATISFACTION

After moving to Cambridge A Tower, the mean score of CA5 overall patient

for the 23 EBD goals, the average score of CA5 is 24% higher than Bell 63 (4.41 vs. 3.33) and the average score of CA6 is 18% higher than Bell 64 (4.56 vs. 3.73).

satisfaction ratings improved from 91.5 to 92.2, which is an increase of 0.8 percent, and the mean score of CA6 also improved from 89.3 to 90.8, which is an increase of 1.7 percent. Since we didn’t have access to monthly data and individual patient-level data, we are not able to conduct statistical analyses to determine the significance of these findings.

units have similar visits to patient rooms, but the new design of CA allows nurses to utilize the alcoves more often, hence provide closer contact with patients and family. Team rooms in CA5 and CA6 are frequently used, which can lead to better care coordination and inter-disciplinary communication. There was a reduction in the frequency of patient room visits in CA6 compared to Bell Unit 64.

PART II: INTERVENTIONAL PLATFORM AND SURGERY POE

PREP/ HOLDING

The surgery prep/holding area includes 29 “universal” bays capable of supporting patient preparation and recovery. This model is designed to allow rooms to swing between prep and recovery as demand requires, moving away from the traditional concept of a separate post-anesthesia recovery room. Staffing is currently organized to focus recovery functions at the south end of the unit, with an adjacent bank of rooms that can swing between recovery and prep.

High utilization of the consultation rooms near the family waiting area were reported. We were not able to assess the effectiveness of the split in waiting areas between the first and second third floors.

STAFF INTERVIEWS

Overall, staff interviews indicated satisfaction with the facilities in Cambridge A. Some conflicts with the location of scrub sinks and staff flow were identified. The location of patient toilets in the prep area was cited as a concern, with more central locations suggested as preferable.

remote from the prep area, resulting in holding carts in the corridor of the prep area. Underutilization of space near the case cart/supply elevators at the north end of the floor was also pointed out by staff. The inclusion of a satellite pharmacy and the anatomical pathology area are significant support functions for the procedures performed in this area. 15

near the higher circulation areas of the room (corridor access to the O.R., access to the core, scrub sink access, and the circulating nurse work areas). The location of the control terminal for the Da Vinci unit may also conflict with the return air circulation in the room. The diagonal location of the patient does not take advantage of the laminar airflow concept built into the universal room layout.

PROCEDURE ROOMS

The procedure rooms are in a “mirrored” layout with a single control area between the rooms. The room layouts are functional, with good visual observation into the rooms from the control area. Some procedures require multiple clinical teams and equipment limiting circulation and work areas. We were unable to schedule interviews with staff to assess their feedback regarding this space.

INTERVENTIONAL SERVICES The core interventional imaging services located on the second level of Cambridge A include two biplane fluoroscopy imaging procedure rooms, diagnostic CT and fluoroscopy rooms, holding/recovery, and a waiting area. In addition to the procedure/diagnostic rooms, the holding area also supports prep/recovery for an adjacent MRI room.

One shell area located next to the biplane rooms is sized for

future expansion of these procedures. The area allocated for this service is approximately 15,000 departmental gross square feet. A main public circulation corridor between a staff parking garage and the hospital bisects the waiting area, resulting in a linear configuration. The workload for the interventional imaging procedures is current relatively low for the capacity of the system.

A nursing unit is a basic unit in a hospital or other health care delivery setting that provides the necessary functions for health care professionals to deliver care to their patients. The layout of the nursing unit is strongly driven by the location of nurse station(s) and its relationship to patient rooms and other support areas. Traditional nursing unit design is usually based on one central nurse station located in the middle of the unit to overlook most of the patient rooms. Recently, the contexts in which the healthcare organizations operate have changed dramatically, such as the shift to patient and family-centered care, more integrated care processes and collaborative care models, and rapid updating of technology and equipment. As a result, traditional centralized nurse stations have been gradually replaced by decentralized work stations, for the potential benefits of better patient visibility, increasing direct patient care time, and reducing walking distance. However, debates persist on the impact of decentralized nurse stations on nurses’ communication and coordination. Moreover, there are many variations of decentralized nursing unit typologies. Few empirical studies have compared the effectiveness of various decentralized nursing unit typologies and identified the key elements and characteristics for an optimal layout that can support both staff efficiency, communication, hand hygiene, and better patient experience.

BELL UNIT 64 Bell Unit 64 is configured on a rectangular floor plate, with a race-track corridor system (Figure 5). The primary unit and visitor entry is on the west, and there is one inter-unit entry at the south quadrant on the east. In addition to the nursing alcoves between each pair of patient rooms there are four nursing substations, one each at the east and west ends of the rectangular floor plate and two paired at the center of the unit. These substations anchor a central support core of staff lockers and break rooms, medication, utility and conference rooms, and four private offices. There

is a small family waiting room, a work room and a private office at the west entry. Each patient room has a private patient toilet. The patient rooms are configured in a relatively standardized layout in mirrored plan arrangements. The room size varies from 226 NSF (with a 42 NSF private toilet) to 325 NSF (with a 57 NSF private toilet). The average patient room size (excluding the private patient toilet) is 244 NSF. The overall unit size is 15,600 GSF, which computes to 650 GSF/bed. The average distance from nurse station to patient rooms is 60 feet, the max is 140 feet, and the min is 18 feet. The average distance from nurse station to clean supply is 37 feet, the average distance from nurse station to medication room is 42 feet, the average distance from nurse station to soiled supply is 41 feet. There are no areas within the unit for family/visitor accommodation except in one small waiting room and in the patient rooms themselves.

In all of these units, a number of communication technologies are adopted, including Voalte phones, Sonitor nurse locators, and nurse pagers. Several Workstations on Wheels (WOW) were provided in each unit to support mobility of rounding and charting. In both the ICU units’ nurses have the same amount of workload. In both the ICU units nurse to patient ratio is 1:2. Both acute care units (CA6 and Bel 64) also have similar staffing model and nurse to patient ratio as 1:4 to 1:5. Bell 63 and Bell 64 are compatible control groups for CA5 and CA6.

RESEARCH DESIGN AND GOALS This project aims to empirically evaluate the impacts of decentralized nurse stations through a multi-center, before-and-after,

quasi-experimental

comparative

study in the newly constructed Cambridge A building and the Bell Hospital. It intends to compare one typology of decentralized nursing unit (CA5 ICU and CA6 Progressive care unit) with another typology of decentralized nursing unit with similar staffing models and patient acuity levels (Bell Unit 63 ICU and Bell Unit 64 Medical Transplant Unit) to evaluate the impacts of the physical environment on nurses’ work efficiency, teamwork, hand hygiene, and patients’ outcomes and satisfaction.

RESEARCH METHODS This study combines both qualitative and quantitative methods to examine how various users function in these units with a focus on nurses. Research methods include visibility analyses, noise and lighting measurements, pedometers, behavior mapping and tracking, nurse interviews and questionnaires, and patient satisfaction and outcome analyses.

1. VISIBILITY ANALYSIS OF BOTH PLANS USING SPACE SYNTAX

We used the program Depthmap to conduct space syntax analysis and describe the patterns of visibility.

Moreover, we evaluated the visibility (integration) of the hand sanitizer stations to see if the visual cues of hand sanitizer station impact hand hygiene compliance.

2. NOISE AND LIGHTING

The ambient environment, including lighting and noise levels, was measured in each unit. The noise levels were measured at several sampling points within each unit in the morning and afternoon during the 5-day observation period (Figure 6). The researchers walked along a predetermined path and measured noise at each sampling point for one minute. For the background

3.

noise level measurement, the research team used the Decibel X app and further calibrated with a sound level meter (model number: Larson Davis 831). Noise levels at 18 sample points are equally spaced out in the CA5 unit and CA6 unit. Among them, 4 sampling points (6,8,14, and 15) are inside the decentralized nurse station and the other 14 points are along the corridor. Similarly, noise levels at 15 sample points that are equally spaced out in Bell 64 and 12 sampling points in Bell 63 were

measured. Among them, 4 sampling points are inside the sub- nurse stations (6,10,12 & 14), and the other 11 points are along the corridor in Bell 64; 3 sampling points are inside the sub-nurse stations (3,7&11), and the other 9 points are along the corridor in the Bel 63.

AMBIENT ENVIRONMENT QUALITY : NOISE In total, 1773 readings were taken in four units for the maximum, average, and peak values of the noise levels over morning and afternoon shifts. Detailed numbers of measurements are listed below (Table 2). Based on 144 noise readings, CA6 average noise level is 56.1 dbA, the average noise level for the corridor is 54.8 dbA and the average noise level for nurse stations is 60.7 dbA. By contrast, based on 135 readings, Bell 64 average noise level is 58.3 dbA, the average noise level for the corridor is 57.9 dbA and the average noise level for nurse stations is 58.5 dbA.

The pattern of visibility and accessibility were analyzed with the software ‘Depth Map X’ using Visual Graph Analysis (VGA). In order to conduct the visibility analysis, a set of square tiles were laid on the floor plan of each hospital unit. The software analyzes the relationship of each tile to adjacent tiles and sequentially to distant tiles (Haq & Luo, 2012). For this study only the integration value was calculated to identify the overall visibility and accessibility conditions of each unit, because this value is most relevant to the human movement or human visibility. The visibility of each unit is visually demonstrated with a color coded map through the software. Figure 11a. Bell 63 Visibility

Bell hospital has higher visibility comparing to Cambridge hospital, which means Bell hospital is more visually connected at the sitting height than Cambridge hospital. Among the four units Bell 63 has the highest visibility and accessibility compared to the other four units. On the other hand, CA 5 has the lowest visibility and accessibility compared to the other four units. Better accessibility means staff can easily move from different parts of the unit in Bell 63, when compared to the other four units.

The corridors, nurse stations and nurse alcoves of unit 63 are the most visible and most accessible areas from the rest of the unit when compared with the other three units. The extended ‘z’ shaped layout of CA5 and CA6 produced less visible spaces compared to the straight layouts of Unit 64 and Unit 63. Among these four units, the visibility and accessibility of nurse stations, nurse alcoves and corridors of CA5 are the lowest. 47

BEHAVIOR MAPPING ANALYSIS: NURSE INTERACTIONS Figure 16a. CA 5 Nurses’ Frequency of Interaction with Others

Figure 16b. CA 6 Nurses’ Frequency of Interaction with Others

The nurses of all four units interact most frequently with peer nurses. In the Bell units nurses have a higher frequency of interaction with fellow nurses and patients compared to nurses of the Cambridge units. In Bell 64, about 44.3% of the nurses interact with fellow nurses, which is the highest among the four units. CA6 has about 36.8% interaction between peer nurses, which is the lowest among

Figure 16c. Bell 63 Nurses’ Frequency of Interaction with Others

Figure 16d. Bell 64 Nurses’ Frequency of Interaction with Others

the four units. On the other hand, the frequency of nurse interactions with doctors, nutritionists, and therapists in the CA units is higher compared to the doctor/nurse interaction in the Bell units, which may be attributed to the close proximity of the team room to the nurse stations (Figure 16a-d). In addition, in the CA units nurses interact with the patient family members more often when compared to the Bell Units. It appears the well-designed designated lobby lounge area, consultation rooms and the conference rooms are promoting the additional interactions.

By contrast, the rate of social interaction is higher in the units of Bell compared to the units of Cambridge (figure 17a-d). On the other hand, the Bell units have more social interaction compared to Cambridge. The rate of social

interaction in Bell 63 is 16.3%, in Bell 64 is 11.5% whereas in CA5 it is 5.5% and in CA6 8.9%.This fact also supports our previous findings that the nurses of the Bell units interact with the patients and fellow nurses more than the nurses of Cambridge. The small size, compact layout and higher inter-visibility of the Bell units probably promotes more encounters and spontaneous social interactions than the Cambridge units. Simultaneously, better visibility ensures prompt peer support in Bell when it is needed. In Cambridge the less visible spaces produce less interaction. When the nurses interact in Cambridge they tend to solve work-related issues.

Figure 20d. Bell 64 Value added Activity Vs. Non-Value added Activity

VALUE-ADDED ACTIVITIES AND NON-VALUE-ADDED ACTIVITIES In order to fully understand where the nurses were spending the majority of their time, a further analysis of value-added versus nonvalue-added tasks was completed. A non-value-added task was considered a task that took unnecessary time to complete due to distance traveled, such as delivering or retrieving an item. A valueadded task was a task essential to the well-being of the patient, such as patient care, care coordination, documentation, assessment of vitals, family care, or administration/teaching. Nurses in both the units of Cambridge are involved in more value-added activities compared to the nurses in the Bell units. When comparing the two progressive units, 78.4% activities of nurses in CA6 are value-added activities, whereas 70.3% activities of the nurses of Bell 64 are valueadded activities. When comparing the two ICU units, 84.2% activities of nurses in CA5 are value-added activities, whereas 82.3% activity of the nurses of unit 63 are value-added activities (Figure 20a-d).

Figure 21b. CA 6 Nurses’ Posture

Nurses of the progressive units (CA6 and Bell 64) walk more often than the nurses of the ICU units (CA5 and Bell 63). On the other hand, nurses of the ICU units do more tasks while standing than the nurses of other two units. 30.7% of the posture of the nurses of unit 64 are walking, which is the highest compared to the other three units. The high frequency of looking and retrieving activities in Bell l64 could impact the higher frequency of walking. On the other hand, 47.2% of the posture of the nurses in CA6 are sitting, which is

Figure 21c. Bell 63 Nurses’ Posture

the highest compared to the other three units (Figure 21a-d). It seems that the distributed supply rooms allow CA6 nurses to have less frequent walking for looking and retrieving supplies.

WALKING DISTANCE COMPARISON BY UNIT TYPOLOGY

WALKING DISTANCE USING PEDOMETERS

The RNs in CA6 (M=7062, SD=2369) walked significantly more than Bell 64 (M=5941, SD=1675), t (113.597)=3.057, p<.05 (Figure). On average, the Bell 64 nurses walk about 2.81 miles and the CA6 nurses walk 3.34 miles. The RNs in CA5 (M=5098, SD=1392) also walked significantly more than Bell 63 (M=4030, SD=1171), t (138)=4.877, p<.001 (Figure). On average, the Bell 63 nurses walk about 1.91 miles and the CA5 nurses walk 2.41 miles (Figure 23).

The actual walking distance was further analyzed by capturing the steps taken per shift using pedometers. In total, 276 sets of walking distance data were collected. Among them, 264 sets were for RNs and 12 sets were for float nurses. We kept the 264 sets of all RN data for final analysis, 124 sets in the progressive care units (60 sets in Bell 64 and 64 sets in CA6) and 140 sets were collected in intensive care units (66 sets in Bell 63 and 74 sets in CA5).The

WALKING DISTANCE COMPARISON BY SHIFTS

Overall, RNs walked more during night shifts (MD=318 steps). Interestingly, there is no clear difference of walking distance between day shift and night shift nurses in Bell 64 (MD=15), while a statistically significant difference in CA6 (MD=1490, t(46.975)=-2.63, p<.05). The difference can be contributed to the more linear and linear layout of the decentralized nursing unit in CA6, requiring nurses to walk more to check multiple patients who require closer surveillance during the night. Another interesting finding is that nurses in CA5 walked less during the night shift, perhaps due to the fact that they only have 1-2 patients, the nursing alcove allows them to stay close to the assigned patients for visual surveillance, while Bell 63

results showed that RNs in the progressive care units (Bell 64 and

nurses walked slightly more during night shift, although the differences were not

FALL RATES

Patient falls occurring during hospitalization can result in serious and even potentially life-threatening consequences for many patients (NDNQI, 2016). Both unassisted and assisted falls are included in fall rates.

INFECTIONS RATES (CDIFF, HAPI, CLABSI)

Central Line-Associated Bloodstream Infection (CLABSI) rate is calculated by the number of CLABSI divided by Central Line Days times 1,000. For CLABSI, there were very few incidents in all units. Clostridium Difficile (C. Diff) rate measures the events of C. Diff and it is related to hand hygiene and the overuse

Behavior tracking helped to capture time and motion by recording locations and

duration of various nursing activities including hand washing behavior. Data was collected in two consecutive weeks in both the morning shift and the afternoon shift by a group of students. The observers followed one volunteering nurse for a continuous hour and recorded activities using task type, task category, and location. With the participation of 10 nurses, the number of total activities recorded in unit 64 is 312, including 60 hand hygiene occurrences, whereas in Unit 63 total activity was 232, including 34 hand hygiene occurrence. Similarly, in Cambridge 6, number of total activities were 246, including 25 hand hygiene occurrences, whereas in Cambridge 5 total activity was 298, including 52 hand hygiene occurrence. Locations of hand hygiene occurrences of Bell 64 and Bell 63 are identified in Figure 28a & 28b, similarly the red numbers in Figure 28c & 28d demonstrates the hand hygiene occurrences of Cambridge 5 and Cambridge 6. In Bell 63 the total number of hand hygiene occurrence was 34, however the Bell 63 unit contains only 24 hand hygiene stations. On the other hand in Cambridge 5 total number of hand hygiene occurrence was 52 in 40 hand hygiene stations (Figure 30).

The data demonstrate that Bell 64 contains the lowest number of hand hygiene stations (23) , although the hand hygiene occurrence rate in this unit is 19%. In the other hand, CA5 contains the highest numbers of hand hygiene stations (40) but the hand hygiene occurrence rate in this unit is 17% . CA6 contains 32 hygiene stations, but the hand hygiene occurrence rate in this unit is 10%. In Bell 63 the hand hygiene rate is 15%, and number of hand hygiene stations are 24. The results demonstrate that the number of hand hygiene occurrences do not depend on the number of hand hygiene stations. The overall visibility of the two units of the Bell hospital is higher compared to the overall visibility of the two units in the Cambridge hospital. Additionally, both the average visibility (9.027) and average accessibility (7.602) of the hand hygiene stations in the two units of Bell are higher compared to the average visibility (6.233) and average accessibility (5.931) of the hand hygiene stations of the two units in Cambridge. Therefore, the hand hygiene occurrences in the two units of Bell hospital is higher than the hygiene occurrences in the two units of Cambridge. 79


PATIENT ROOM POE Based on the Center for Healthcare Design standardized patient room POE toolkit, for the 23 EBD goals, the average score of CA5 is 24% higher than Bell 63 (4.41 vs. 3.33) and the average score of CA6 is 18% higher than Bell 64 (4.56 vs. 3.73).

STAFF SUGGESTED DESIGN IMPROVEMENT

STAFF SUGGESTED PATIENT ROOM IMPROVEMENT (CA 5 & CA6) 1.

The patient rooms are not standardized; some rooms are much larger than others, especially the ones at the corners of the bends, which makes the room layout less consistent across the unit;

2. Lack of counter space; 3. Scanner is hard to reach and the cable is too short; 4. It would be nice to have ceiling lifts in every room. Currently, only four rooms have ceiling lifts. The Figure 31a.

facility team have to be called in every time to move the motor to the rooms that need lifts. 5. The boom in CA5 seems unnecessary. As long as there is a movable monitor, it would be fine. The boom is less mobile when you have a lot of wires attached to it anyway (Figure 31a); 6. There are multiple tracks on the ceiling: boom arm, ceiling lift track, curtain, IC hook. The ceiling mounted IV can sometimes get in the way when the

nurses try to move the hook or ceiling lift (Figure 31b); 7. There is a conflict between the location of the supply cart and the computer. Nurses frequently hit their heads when trying to get supplies from the cart. Maybe change the computer to be wallmounted instead of on the arms (Figure 31c).

Figure 31c. 83


STAFF SUGGESTED PATIENT UNIT IMPROVEMENT Overall staff are satisfied with the aesthetics of the units and the (CA 5 & CA6)

adjacencies of supply rooms to each team hub. They also had some suggestion to further improve the design. 1.The curvilinear shape and the bend seems to create a barrier for continuous visibility in the unit. Staff found it hard to see the call lights on the top of patient rooms from nurse stations or from the alcoves. It can potentially increase nurses’ walking distance. 2.One of the team rooms could use lower partitions for better visibility. For instance, the north team room is used mainly by the therapists and can remain with translucent partitions. The south team room is mainly used by nurses and it can use low partitions for better visibility and nurse teamwork. 3.The nurse station desk is closed on one end can make it harder for nurses and unit clerks to get to patient rooms. 4.There are only two public restrooms on the north end of the corridor. For patients who are assigned to the south end, their family members have to travel long distances to use the bathroom. There is only one staff bathroom on the south side of the unit, while three staff bathrooms are on the north side. Staff sometime have to travel long distances to use the bathrooms, and the staff bathrooms need door codes to guarantee staff use only. 5.The break room is well-designed, however it is a bit far removed from the patientcare area, and sometimes nurses will have their meals in the south team room instead to stay close to their patients. The current page system only displays the room number and the initial of the patient. For nurses to see the full information, they have to check the computers to see the details for patient-safety considerations. Adding a computer in the break room can help nurses use the break room without

INTERVIEWS WITH UNIT MANAGERS AND A SAMPLING OF NURSING STAFF SUMMARY Semi-structured interviews with the four unit managers and a random sample of awareness interviews with between nine and fourteen nurses on the four units were used to collect anecdotal data about the perceptions of how the units operated on a daily basis, the environmental quality of the units, and how the design of units could be improved. The unit managers emphasized that each unit design must be matched with specific operational and staffing strategies to insure that positive patient outcomes and nurse satisfaction were maximized. All the managers were satisfied with the ways their own unit layouts and designs created a positive care model. The managers in Bell Units 63 and 64 thought the compact central cores, square or elliptical floor plates, and even distribution of nurse stations contributed to efficient operations and allowed nurses to match daily assignments with a variety of home bases. Their primary concerns in Units 63 and 64 were the small size and nonstandardized configurations of the patient rooms, the noise created in the compact core design, and general lack of storage and family-support spaces.

Nurses on Bell Unit 63 were positive about the size of the unit, the compact central arrangement of nurse stations and support core, and ability to communicate effectively with their colleagues. The compact unit layout contributed to good surveillance of patient rooms and other nurses but also caused excessive noise and crowding, especially during rounds. The small patient room sizes, non-standard layout, and lack of storage were concerns of the nursing staff. The extent and configuration of computers throughout the unit were evaluated positively. Similar opinions were expressed by nurses in Unit 64 as those in Unit 63, except the former were not concerned about small patient-room size or non-standard room configurations. Nurses on Cambridge 5 were positive about the patient-room sizes and standardized configurations, placement and number of computers throughout the unit, the aesthetic quality of the unit, and the location and design of the team room and support areas. They felt they were prepared for the transition to the new design and attributed the success of the unit to daily staffing assignments to maximize nurse efficiency with appropriate home base locations. The most consistent concerns were focused on the unit size for critical -care patients, the length and isolation of the two corridors, the visibility difficulties caused by the corridor bends, and the sense

Their primary concerns were focused on the length of the units, visibility difficulties caused by the bends in the floor plates, and the isolation of the staff along the corridor lengths and across the opposing corridors.

RESEARCH DESIGN AND GOALS

PART II

KU HEALTH SYSTEM INTERVENTIONAL PLATFORM AND SURGERY POE REPORT BACKGROUND Dramatic changes have occurred in the delivery of interventional care since the

SETTINGS

opening of the Bell Hospital in 1978.

Robotics, ambulatory care, interventional

imaging, and new surgical techniques have resulted in major changes to the facilities required to offer functional, safe patient care.

The new Cambridge A building

has provided the University Hospital with an opportunity to design interventional services space based on contemporary concepts and need.

RESEARCH DESIGN AND GOALS This evaluation focused on the analytical analysis of space utilization in the surgery and interventional imaging sections of Cambridge A, along with limited observation and interviews of staff. Due to the numerous modifications to the original spaces in the Bell Hospital, a comparison of the functionality of two environments was assessed to have limited value. Patient survey responses for care provided in these specific hospital areas were limited, resulting in the inability to integrate this input into the assessment.

SETTINGS The core of interventional service is located on the second and third floor of Cambridge A. Central Sterile and additional family waiting spaces are located on the first and basement levels. These floors are connected to the other hospital facilities via a two level pedestrian bridge linking Cambridge A across 39th Street to buildings on the south side of the street. The core of staff lockers and lounge spaces are located on the second floor of Cambridge A, shared with the Interventional Imaging service.

105


SURGERY

The third floor, and portions of the second floor, of Cambridge A are dedicated to surgical services. The primary procedures are cancer procedures performed by Neurosurgery, ENT, Orthopedics, and General surgery services. Support for other University Hospital cases are provided as needed, primarily on the weekends.

PREP/ RECOVERY AREA

The prep/recovery area is designed to “flex” during the day as workload volumes shifts from prep functions to recovery. There are 29 “universal” bays. Currently, two of the bays are dedicated to Cardiology for ultrasound procedures, and one room is mostly used as for equipment storage. There is one isolation room near the entry to

of the operating rooms area focused on neurosurgery, with one room directly connected to the MRI (Figure 32).

During the most recent six month, 3,351 cases were performed in the eleven staffed operating rooms. Most of these cases were inpatients or same day admits. The complexity of procedures performed result in long procedure times, averaging almost three hours (Table 15). The total departmental gross square footage assigned to this service is 47,464. This includes essentially all the third level, 80% of the staff support areas on the second level, and a small waiting area on the first floor. This result is a ratio of 4,300 DGSF

per operating room. This is significantly high than typical referenced ratios of 3,000 – 3,500 DGSF per O.R. Several factors contribute to this higher ratio.

PREP/ HOLDING AREA

The prep/holding area is designed to allow flexible assignment of patient bays

Figure 34. Surgery prep/holding area

between pre-surgery preparation and post anesthesia recovery. A typical bay is 134 net square feet.

Observation and interviews with staff indicate that the bays

are appropriately sized for the care provided. During the initial occupancy of this area recovery patients were distributed throughout the available beds. The current practice is to consolidate recovery patients at the south side of the unit, with a bank of six rooms in the middle swinging as needed between prep and recovery care functions. Staff reported the consolidation of recovery provided efficiency and that family and patients traveling to the prep area did not have to pass by recovering patients that might be in discomfort. A two-week sample of bed utilization found the peak demand for beds in this area was 16, occurring during the late morning period. The ratio of peak bed needs to staffed operating rooms is lower than for typical surgery suites, primarily due to the long case times and the resulting average of 2.4 cases per operating room (Figure 33). Figure 33.

The original layout of the holding bay rooms was designed to have a primary staff and family zoning areas within the room, with the staff work area along the left side (facing) of the patient gurney, and family seating along the right side. The installation of the computer work station at the headwall resulted in the need to relocate the mobile supply cart to the right side of the room. This requires staff to frequently pass in front of the family to access supplies (Figure 34). Computer workstations are in multiple locations including decentralized terminals between holding bays. Observation and staff comments indicate that the decentralized workstations are frequently used by medical staff in addition to nursing, making the terminal in the patient bay area an important backup. A moveable partition between every two rooms is intended to allow staff to move quickly between patients if close supervision is required. This capability was not used during the limited observations in the area. Staff report periodic use for patient care in the recovery phase and more limited use in during preparation. Staff pointed out that this is a good feature to have when considering potential long-term changes in patient care needs over the life of the facility.

109


Observations in the unit found that some conversations could be heard between bay areas, particularly if the moveable partitions were not fully closed. The overall sound levels in the unit fell into a low range. Sample reading in different locations

OPERATING ROOM SUITE

show an average range between 55 and 66 decibels, with limited ability to discern conversations in the patient bays. This contrasts with Bell PACU North. Although the decibel readings were only slightly higher in north, there was not patient and family privacy in the recover pod areas. All conversations could be overhead in this unit. The current staffing pattern for the unit is based on geographic assignments of staff to four to six adjacent patient bays (Figure 35). This limits the overall amount of staff walking. Storage and supplies were not identified as a major concern, although storage of gurneys was in the hallway area at the south end of the unit

STAFF INTERVIEWS Interviews with staff found overall satisfaction with the configuration and functionality of the operating rooms. Among the comments and issues identified were the following:

• The need for a third surgical light, particularly in the rooms assigned to ENT and where two surgical teams may be working on the patient at the same time. • Questioning of the functionality of the second power boom in the operating room. Staff interviewed indicated that most of the time it was not used and was an impediment to circulation around the operating room table. • The difficulty in opening and the closing times of the doors from the perimeter corridor into the operating rooms. The option of sliding doors was suggested as potentially easier to use and could create less air turbulence within the O.R. • The location of the two scrub sinks outside the neurosurgery operating rooms #2 and #11 were cited as problems due to staff using these sinks rather than the sink inside the neuro core area. Staff noted that this results in staff entering the operating rooms through the patient entry and into to non-sterile area of the room. • It was suggested that a small, potentially folding, metal shelf would be beneficial Figure 38. Operating room set up with Da Vinci unit for ENT cases

The HVAC system is designed to provide “laminar,” unidirectional air flow across the surgical field. Again, in the ENT room it is not clear the impact of rotating the operating room table has on this concept.

It was also

next to the anesthesia primary work area to allow discarding of items used by the anesthesia team. Currently these items are frequently placed on the anesthesia machine, the circulating nurse work desk, or other locations. • A small alcove area along the corridor at the entry to the operating room suite would remove gowning activities along the corridor area.

noted that the Da Vinci control unit and other equipment were place near the return air duct in the O.R., potentially compromising the air flow concept.

Figure 40. Interventional services prep/recovery room

The departmental gross area per diagnostic and procedure rooms is 3,700. This ratio is high due to the shell room included in the service and the capacity of the holding area for other services. The two special procedure rooms are sized at 622 net square feet and 625 respectively.

Figure 41. Intenventional imaging prep/recovery bed utilization rate

The prep/recovery area is organized into a “ballroom” configuration, with open-bay rooms wrapped around a central nursing station. There is one holding room design for isolation care. The average bay size is 122 nsf. These holding rooms do not have the movable partitions seen in the surgery area. This results in the ability to keep the supply cart on the “staff” side of the patient bed (Figure 40). The current mix of patient includes outpatients and inpatients primarily from the Cambridge A inpatient units. Patients are prepped in the holding area, with critical care patients typically moving directly from the inpatient unit to the procedure area. Inpatient may also be moved directly from the procedure area back to the inpatient unit. A two-week sample of patient bed use throughout the day indicate ample current capacity (Figure 41). This area could accommodate the conversion of the shell space into an additional procedure rooms.

Figure 42. Interventional radiology procedure room

The size of the procedure rooms appears appropriate for the mix of procedures (Figure 42).

Our team

observed a neuro angiography case involving twelve medical, anesthesia, nursing and other personnel in the room.

The shared control room between the two

procedure rooms provided sufficient area for staff supporting each room without interfering with each other. We were unable to schedule staff interviews to obtain feedback regarding the performance of this unit.
