Learning Objectives Assuming ubiquitous adoption in Healthcare for RTLS, Passive RFID and mobile indoor location, understand the future financial requirements. Increase understanding of the feasibility and benefits of an enterprise location infrastructure designed for many use cases. Increase understanding of the feasibility and benefits of embedded tags and the importance of infrastructure standardization.
Kaiser Permanente 7 regions serving 8 states and the District of Columbia 9.1 million members 17,000 physicians; 175,000 employees (including 48,000+ nurses) 38 hospitals (co-located with medical offices) 600+ medical offices $53 billion annual revenue $1.8 billion invested in our community 68 years of providing care Decision: Work with suppliers to embed RTLS tags into medical equipment.
Types of RFIDExamplesVisual Passive Supplies Specimens Pharmacy Active / Real-time Location Systems (RTLS) Assets Patients Mobile Indoor Location SmartPhones Tablets GPS Specimen Temperature In-Transit Tracking What is RFID? Radio Frequency IDentification is technology that uses communication through the use of radio waves to transfer data between a reader and an electronic tag attached to an object.

Passive RFID Retained Foreign Objects Medication (Pilot) Lab Specimens (Pre-Pilot) 3. Mobile Location Wayfinding (Pre-Pilot)
Future Examples - More Infrastructure x3 Members can find the facility using GPS, and then once indoors navigate using indoor location to their doctors appointment. Mobile Indoor Wayfinding Asset Tracking – Enhanced Location Accuracy Nursing and Clinical Technology can quickly find needed equipment by knowing the exact room the equipment is in. Accuracy enables advanced equipment/patient workflows as well (e.g. par levels). Nurses can track the location of on demand medications in transit; plus know when and where they are delivered to.

This is merely an illustration with rough approximations which includes several assumptions around widespread use case adoption, coverage requirements, location accuracy and future support costs for all three infrastructures.

Bluetooth Low Energy (BLE) looks promising for mobile and retail applications. iPhones are sensors too. Could it be used for more? Feasibility Which technology(ies)? Benefits One Infrastructure = Cost savings. Industry growth through greater use and adoption. Increases attractiveness for suppliers to design in.
Embedded Location Feasibility and Benefits Progress - Examples Kaiser Permanente is deploying select gauze with passive RF tags built in by the suppliers. 6+ Years Ago, Kaiser Permanente Clinical Technology Identified this as a future requirement for RTLS tags. Today Kaiser Permanente is starting to address this issue with its strategic medical device manufacturers. Intel announced an initial step Mobile indoor location applications are emerging – using mobile embedded location already. Feasibility Lacking a comprehensive RTLS standard for sensors and tags. Note: It is expected active tags will always be required for medical equipment that doesnt have a battery (e.g. standard wheelchairs) Benefits Reduces initial and ongoing costs for tags. Doesnt fall off. Small/Zero form factor.
Future Recommendations Be Prepared and Contribute: Encourage the advancement of standards for embedded RTLS, making it possible for standards to emerge more quickly enabling industry-wide embedded RTLS. Where possible, encourage blending RTLS with passive and mobile, which can increase the value of the infrastructure/sensors through reuse. Learn from mobile; plan for mobile users and encourage greater use of additional onboard sensors for enhanced location accuracy (e.g. accelerometers, pedometers). Help encourage integrated GPS location with indoor mobile location for use cases such as seamless door to door wayfinding (e.g. home to parking lot to doctors appointment).
Driving Value in the Present In the meantime, we will continue to use the technology to create the most value: – Make it easier for clinicians to do their jobs – Service more patients – Reduce the cost of equipment and supplies – Optimize asset utilization – Drive positive patient and family experiences Things to Consider – What is the return on investment, given the facilitys current state? – What technology best addresses the know use cases and the future use cases? Passive Active Mobile
Summary / Lessons Learned If ubiquitous location infrastructures are adopted (x3), the financial benefits from consolidation are operationally significant. A technology approach that results in a single RFID / Location infrastructure for all use cases which maximizes sensor reuse is likely to lead to the lowest long term cost. Location is embedded in mobile devices already for GPS, and is an emerging reality for indoor location. RTLS could accomplish the same providing standards are available. Single Network + Embedded Tags = Increased Value and Faster Industry Adoption.
