2 ABSTRACT Healthcare is at a cross roads. The combination of economic down-turn, reduced reimbursement rates, rising complexity of regulations, and uncertainty of the future has placed extra strain on hospital management, employees, and associated medical staff to accelerate their efforts to change. Although quality and performance improvements have been areas of focus in hospitals over the years, operational excellence, breakthrough process redesign, and establishing organization-wide cultures of change and continuous improvement have become strategic imperatives throughout healthcare. These strategies require an optimum blend of people, process, and technology to deliver the kinds of cost, quality, and capacity improvements required for the future. This paper will discuss current trends in process improvement initiatives at hospitals and the role that a single enterprise-wide real-time visibility platform can play in performance improvement by automatically capturing location and sensory data throughout the hospital and seamlessly integrating the information into the appropriate clinical or non-clinical system. REAL TIME LOCATION SYSTEMS (RTLS) IN HEALTHCARE Knowing where patients are as their care journey progresses through the hospital, capturing the time and location of care delivery events and activities, and locating the nearest available piece of critical medical equipment are just a few of the potential applications for Real Time Location Systems (RTLS). RTLS uses a breadth of technologies RTLS uses a breadth of technologies to enable real-time, automatic sensing of location of people and objects. The solution consists of battery operated tags either fixed to an asset or worn by a clinician or patient, a centralized middleware element for graphical user viewing of asset locations and management, and a wireless network infrastructure to connect tags to middleware. PVA's core competency is the wireless network infrastructure. PVA's capabilities comprise the following: Site survey and network assessment to determine if an existing wireless network has adequate coverage and network bandwidth Site survey of a greenfield design to analyze floor plans and building materials to develop heat maps Engineering and design of where wireless access points should be placed in a facility Procurement of equipment Installation, integration and ongoing maintenance of the sensor wireless network. 2

The software provides visibility and manages the flow of information associated with location, condition, and event documentation throughout a complex healthcare facility or network of facilities. It can provide the backbone to enable "visibility" information to reach the appropriate system (EHR, Bio-medical, Asset Management, Nurse Call, Security, etc.) or directly to individuals through portals and specific applications (equipment location, patient status kiosks, temperature or hand-wash compliance). At the core of the asset management platform is a comprehensive middleware layer and flexible application platform that supports a breadth of RTLS and sensor devices and interfaces with a growing list of existing software, communication, and building systems and applications. The end result is a single software platform that cost effectively provides the means to automatically capture and integrate real-time activity and event data into systems used to support workflow and other operational process improvements. The sensor wireless network utilizes the OmniAccess access points. These unique access points support multiple channels and can be configured in a mesh design to provide redundancy for 3

These access points support Adaptive Radio Management which allows the wireless network to adapt to environmental changes, quality of service conditions, and traffic demands. The access points are auto-sensed by the controller which minimizes any installation efforts. The OmniAccess controller consolidates the access points for connection to the facility local area network for connection to other resources. It also provides management capabilities and reports to look at various conditions on the network such as utilization, packet traffic and losses, and RF conditions. Embedded in the controller software is the ability to plan and design a precise wireless network based on specific floor plans and to deploy the configuration from a single portal. This system design has been integrated with other major RTLS technologies including, RF/Infrared, Zig-Bee, Ultrasound, and Passive RFID for more precise tag locating with less than 1 meter of variation. It also interfaces with a breadth of facility monitoring systems, including temperature & humidity, fire alarms, doors & windows, video, and elevators and security monitoring systems, including access control, motion sensing, door locks, visual alarms, and audible alarms. Additionally, the system has also been interconnected with existing nurse call, telemetry, fall detection, and infant protection systems in hospitals and senior care facilities. This breadth of connectivity is important as healthcare continues to be a very complex industry with significant diversity from hospital to hospital as to IT systems and strategies, especially as it relates to non-clinical systems. ASSET MANAGEMENT Asset Management is the ideal starting point with RTLS solutions. First, optimized asset management with enterprise RTLS can provide measurable hard-dollar cost savings and return on investment. Second, from an organizational change management perspective, tracking assets is less disruptive and easier to accept than tracking people. Third, starting with asset management provides a solid foundation for leveraging enterprise RTLS to enhance other processes, such as patient flow. In terms of current process improvement trends, an asset management system can address all three process improvement areas: eliminating waste (Lean), reducing variability (Six Sigma), and improving capacity (workflow). Waste is evident in excess inventories of equipment and in the time required for staff to hunt down and locate equipment. This waste shows up on the bottom line of a hospital through excess equipment rental cost, extra labor cost, and working capital in the inventories of excess medical equipment. By implementing an RTLS-based asset management system, variability can be reduced by having the right mobile medical equipment at the right place and at the right time. Variability can also be reduced by combining condition information with location to ensure that equipment is clean and maintained to appropriate revision level and preventative maintenance schedules. Ultimately, the variability of equipment utilization can be dramatically reduced when real-time location information can be combined with equipment management processes. 4

5 Asset tracking also impacts workflow and capacity. When critical equipment is not available when required, delays in care delivery occur. This is true throughout the hospital including the emergency department, operating rooms, patient rooms, diagnostic and other procedure departments. Delays in any area can cascade throughout the hospital and have significant impact on the overall capacity of the facility CONCLUSION As hospitals determine process improvement as a strategic imperative, it will be critical to embrace an enterprise-wide focus to overall reduce fragmentation of services and departments. As organizations elect to formally pursue Lean and Six Sigma as their quality improvement methods of choice, they will need to address waste, variability, and continuity of care across their organizations in order to deliver high quality care in a cost effective manner with sufficient capacity in order to be sustainable in the future. Similar to an Enterprise Resource Planning (ERP) system in manufacturing, an RTLS Platform can provide the backbone to ensure that real-time information regarding the location and condition of assets, people, and care delivery events can be captured and utilized in applications throughout the organization. Having real-time actionable information about patients, staff, and critical assets is essential for hospitals to better manage their resources and deliver high quality care at the lowest possible cost. 5
