Conflict of Interest Disclosure

  • Scott Phillips has no real or apparent

  • conflicts of interest to report

Kaiser permanente
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

  • $53billion 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.

What is rfid
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.

Current RFID Use Cases at Kaiser Permanente

Active RFID Tag Adoption

  • 1. Active RFID (RTLS)

  • Asset Tracking

  • Equipment Maintenance

  • Rentals

  • Temperature Monitoring

  • Infant Safety

  • Patient Activity (Pre-Pilot)

    • 2. Passive RFID

  • Retained Foreign Objects

  • Medication (Pilot)

  • Lab Specimens (Pre-Pilot)

  • 37 of 38 Hospitals &

    337 of 600+ MOBs

    • 3. Mobile Location

  • Wayfinding (Pre-Pilot)

  • Implementing

    Active RFID Geographical Activity


    Future examples more infrastructure x3
    Future Examples - More Infrastructure x3

    Members can find the facility using GPS, and then once indoors navigate using indoor location to their doctor’s appointment.

    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).

    Medication Tracking

    Nurses can track the location of on demand medications in transit; plus know when and where they are delivered to.

    Mobile Indoor Wayfinding

    • Exploratory

    • Today

    Summary – More Infrastructure x3

    Could the Future be Room Level or Better for 3 separate location networks?

    If not, what rooms would be excluded?

    Room Level or Better RFID Infrastructure x3

    Future hospital floor with room level coverage x3

    Room with multiple sensors and RFID tags

    Room Level Location Networks x3 - Estimated

    Note: These are not actuals. 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.

    Sensor Consolidation Feasibility and Benefits

    • Traditional Implementations

      • Consumables  Passive RFID

      • Assets  RTLS proprietary networks

      • Mobile  Absent of Indoor Location

    • Future Opportunities

      • Passive Remains + assist RTLS?

      • RTLS – Standardized?

      • Will Mobile Dominate? -> Consumer Wi-Fi + BLE?

    • Feasibility

      • Which technology(ies)?

    • Benefits

      • One Infrastructure = Cost savings.

      • Industry growth through greater use and adoption.

      • Increases attractiveness for suppliers to “design in”.

    • Bluetooth Low Energy (BLE) looks promising for mobile and retail applications. iPhones are sensors too. Could it be used for more?

    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.

    • Benefits

      • Reduces initial and ongoing costs for “tags”.

      • Doesn’t fall off.

      • Small/Zero form factor.

    • Note: It is expected active tags will always be required for medical equipment that doesn’t have a battery (e.g. standard wheelchairs)

    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 doctor’s appointment).

    Driving value in the present
    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 facility’s current state?

      • What technology best addresses the know use cases and the future use cases?

        • Passive

        • Active

        • Mobile

    Summary lessons learned
    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.
