Case Study: Facility Expansion for Improved Flow and Better Access

Case Study: Facility Expansion for Improved Front End Flow and Better Access A Deeper Look Health systems should be designed for optimal patient flow, right-sized waiting and observation areas, as well as ease of access for ambulances and safe access for patients. Expansion and renovation are key tools to allowing facilities to remain nimble and react to patient demands, but planning and phasing logistics must be carefully developed to ensure care to critically-ill patients throughout the project.

Facility Expansion for Enhanced Flow & Safety CHALLENGE Robert Wood Johnson University Hospital needed to improve front-end flow in their Emergency Department (ED), relieve overcrowding, expand & modernize their ambulatory facilities — and maintain a cohesive exterior design in the process.

PROJECT UNDERSTANDING AND CONTEXT An extremely complex project, the expansion and renovation of Robert Wood Johnson’s (RWJ) Ambulatory building was identified as a priority for the Health System. The project occurred concurrently with the expansion of the Core building to the southwest, and it served as the kickoff to a renovation of the ED. One of 17 buildings on the Hospital’s sprawling urban campus, the ambulatory care building is situated next to the ED and houses cardiac outpatient services, EEG, stress testing and echocardiogram, vascular lab and an endoscopy suite. The purpose of the expansion was to provide a safer, more functional parking configuration and entrypoint for ambulances, to relieve overcrowding in the ED by providing space for a new observation unit and to modernize existing facilities.

SOLUTION Reconfigured ambulance parking and an 8,100 SF addition affecting both their ED and ambulatory care center help to provide additional capacity, improve flow and relieve overcrowding. New building features include a redesigned ED walk-in entrance, expanded surgery waiting area, ED waiting area, and shell space for a 21-bed observation unit.

A feasibility study was performed to identify the best course of action for reconfiguring ambulance parking and decoupling overlapping entry points for incoming ED patients and EMTs/ambulances. The study showed a need to relocate the ED entrance, provide additional EMS parking, and address exterior features that did not meet code. Apart for the external flow improvements, the project also addressed the hospital’s need for greater space in select waiting areas in the building, including surgery waiting. Thoughtful design and material selection for the infill construction were essential to unifying the campus feel and vernacular.

With input from clinicians, administrative staff, and close coordination with the RWJ Facilities Department, a multi-phase construction plan was devised to allow the active ambulance bay to remain operational during the improvement process. Input

Design Impact: Perspective from the Field

3 Questions for Leigh Anne Schmidt, Nursing Director at Robert Wood Johnson Hospital

1. WHAT DID STAFF EVALUATE DURING THE DESIGN PLANNING PHASE? We were able to look at the walk-in and the ambulance bays — and how we moved patients to the entrance of the department. One of our big concerns was the EMS arrivals. We treat the EMS just like a patient, and their ease in and out was very important to us. They were very dissatisfied with our old ambulance bay in the community. It was previously a three-bay ambulance spot underneath the building. Now, since the new design, we’re up to nine bays, it’s well-lit, easy to get in and out. There’s an electricity hook up for them, there’s a room from EMTs and administrative teams within the ED was critical to identifying the

AMBULANCE REORGANIZATION Improving the existing ambulance approach and parking required pulling the operation out of the shared public parking garage. A dedicated entrance was established for this purpose, and what was once a shared entrance to the ED was broken into two. Surface-level parking was added, now providing eight

This new building feature prevents ambulances from getting trapped, readies the hospital for higher ED volumes and removes risk associated with a shared entrance.

Expanding the entrance opened the door for the facility to implement new triage bays which lead directly to trauma.

The new waiting area, redesigned entrance, and reconfigured ambulance system operate in tandem to provide the hospital improved front-end flow.

“By creating a more open surgical waiting, it allowed families to feel more comfortable with traveling to Starbucks, Walgreens, or the gift shop and still be within eyeshot of surgical waiting.”

-Faith Orsini, Assistant VP of Construction Services, RWJBarnabas Health

As part of the building’s expansion, the surgery waiting area was enlarged, and the balcony on which in sits was enclosed. The space redesign strengthened the line of sight between the waiting area and coffee shop and pharmacy in the courtyard below, allowing families to feel more comfortable with traveling short distances as they remained within view of surgical waiting. Acoustical panels were added to the courtyard directly below surgery waiting to curb noise, and a new exit area, new public toilets, and new information desk were added to improve the facility’s

a shell space for a 21-bed observation unit was established in the ambulatory building. A pathway to the Core pavilion was also constructed to connect the ambulatory building to provide direct access to the new intensive care units currently under construction, the existing surgery suites, and the respiratory care unit. A dedicated trauma elevator was added to directly link the ED, ORs and ICU overbuild.
