Case Study

On May 1, 2012, The Johns Hopkins Hospital opened its state-of-the-art, 1.6-million-square-foot facility. Initially, the Versus Real-time Locating System (RTLS) was installed throughout for asset tracking and nurse call automation. More importantly, decision makers valued the solution’s ability to scale to additional applications supporting patient flow and staff efficiency. Over the next five years, Johns Hopkins has expanded its RTLS footprint to include nearly all inpatient areas, deploying Versus solutions that support increased productivity and improved care delivery. Today, more than 5,000 sensors are installed in 20 individual buildings spanning 5 acres.

Rigorous Selection Process Locates Best System

As detailed in Healthcare Informatics, Johns Hopkins’ selection team narrowed several RTLS proposals to three, including Versus’ infrared (IR) and radio frequency (RFID) solution, a beacon IR/RFID system, and a Wi-Fi based technology. The finalists were evaluated in a 12,000-square-foot simulation center for their ability to track assets and locate personnel. The Versus RTLS out-performed its competitors with bed-level accuracy and was the only system selected to move on to the pilot stage.1

Asset Tracking: The Foundation for Successful Scalability

When the new facility opened, Advantages™ Asset Management was one of the first solutions deployed throughout. Utilizing the asset platform ensures that care areas have optimal numbers of critical assets available. The intuitive software enables staff to easily locate important assets by using the Enterprise View™ List and Floorplan.

On-Time Cardiac Case Starts Improve 25% with Effective Asset Management

In specialized care areas, such as the Operating Room, surgical delays were often caused by missing equipment, particularly IV pumps. With 33 new state-of-the-art operating rooms, and the need for large numbers of medical devices for each surgery, the cardiac OR team sought to better manage high-demand assets and reduce surgical delays. Utilizing Versus to locate the needed assets, staff review pump availability each night and stage the equipment for the next day’s cardiac surgeries. When this method was launched in 2016, on-time case starts improved by 25% for cardiac cases2, while reducing frustrations for staff, patients and waiting family members.

Environmental Services Doubles Productivity for Service Carts

Prior to using Advantages Asset Management, stocking environmental services carts for an institution the size of Johns Hopkins was a stressful, time-consuming task. Typically, one 8-hour shift was dedicated to finding and stocking 30 service carts. By affixing the carts with Versus asset tags, staff gained clear visibility to cart locations, allowing more than 60 service carts to be stocked during the same 8-hour shift.3

“Our new home represents our vision for healthcare. It has the space and technology to match our researchers’ scientific knowledge, our faculty’s medical acumen, and our staff’s clinical skills, but it also adds the patient experience as the fourth critical dimension in this equilibrium.”

—Edward Miller, M.D.,
Dean and CEO of Johns Hopkins Medicine4

Visibility Staff Assist Enhances Safety in Busy Adult Emergency Department

The safety of staff and patients is critical for healthcare executives and leadership. Although violence against healthcare workers and patients could happen during any point in the care continuum, emergency departments tend be at a higher risk for acts of violence against patients or staff. Visibility™ Staff Assist gives medical staff the ability to send an emergent alert for help, using the Versus badges. When the badge button is pressed, security is immediately alerted, sending messages to wireless phones, computer workstations and email. The messages contain essential information including the name of the person needing help and exact location, allowing security and staff to respond immediately.

Researchers Measure Patient Ambulation with RTLS for Peer-Reviewed Study

In a study published in The Archives of Physical Medicine and Rehabilitation5, Johns Hopkins researchers reveal that patient ambulation is accurately and automatically measured by the Versus RTLS. Selected patients in the neuroscience inpatient unit wore Versus badges during a two-minute walk test. Adhering to stringent study protocols, researchers found that Versus accurately captured two key mobility metrics with high accuracy: the distance traveled by the patient and the ambulation speed of the patient.

While promoting ambulation during acute care hospitalization is critical to successful patient recovery and reducing readmission rates, traditional mobility measurements often rely on physical observations and manual recording. By leveraging the existing Versus RTLS infrastructure at Johns Hopkins, researchers established that clinicians can effectively and accurately support patient ambulation initiatives without burdensome manual methods.

Expansion to the Next Phase: Patient Flow

Based on many successful outcomes using Versus across the campus, Johns Hopkins continues to design additional phases of expansion. Opening in 2018, the brand-new Skip Viragh Outpatient Cancer Building will use Versus Advantages™ Clinic for Oncology to optimize patient flow.
