  1. Evaluation of Active RFID in the Perioperative Context Duncan Clarke Fremont Associates, LLC Camden, South Carolina

  2. Outline • Introduction • Experimental Environment • Candidate Company & Result • Conclusion

  3. Introduction • Operating Room of the Future (ORF) project at University of Maryland Medical Center (UMMC) in Jan 2005.

  4. Experimental Environment

  5. Ekahau • Finland • 802.11 • (x, y) position • T301 Tag • 45 x 55 x 19 mm • 50g • 1 year battery life

  6. Ekahau

  7. Sonitor • Norway • Ultrasound • A nearest reader location • Tag-E Tag • 56 x 32 x 18 mm • 23 g • 5+ year B.L.

  8. Sonitor

  9. Radianse • Massachusetts, USA • RF+ infra-red light • Zone-level location • Tag • 45 x 73 x 19 mm

  10. Radianse

  11. UbiSense • Cambridge, USA • Ultra-wideband RF • (x, y, z) position • Tag • About 170 x 120 x 10 mm • 45g • 1 year B.L.

  12. UbiSense

  13. Agility Healthcare • Richmond, Virginia, USA • Two different frequency • Zone-level location • Tag • Asset tag: 24x 48x 8, non-replaceable, 8.3g • Wrist tags: 25x 38x 11, replaceable, 7g

  14. Agility Healthcare

  15. Exavera • New Hampshire, USA • RF • (x, y) location • Tag • Bracelet, Badge, Asset Tag

  16. Exavera

  17. Conclusion • Location data accurate is within 3m, but below any standard for safety-critical perioperative system. • UbiSense might allow differentiation of individual person or object within a room. • But it’s still in controlled environment. • Another consideration is the ability to scale up for hospital-wide deployment.
