  1. Practical PDAs: Handhelds for the Real-World Presented by: William Lawson, CTO of MercuryMD Frank Fortner, Sr. Vice President of Iatric Systems

  2. Objective Understand factors that influence successful adoption of handheld technologies in the healthcare enterprise.

  3. Technology Adoption Impact

  4. Handheld Use • 31 percent of the nation’s physicians use PDAs as part of their professional duties today. (Gartner Group) • Physician usage of all wireless applications – including pagers, cell phones and PDAs – is currently over 95 percent.(MoHCA) • Use of PDAs for billing functions tripled from 1999-2001. (Gartner Group) • 75% of PDA software products were for drug reference guides. (Gartner Group)

  5. Handheld Use (2001 – 2007 projections by Gartner Group)

  6. Handheld Use Scenarios

  7. User Adoption … but it’s too slow. … but it only works in the hospital. … but what if I lose it? … but the screen is too small. … but the battery doesn’t even last one day. … but I prefer Palm (or PocketPC). … but the wireless network doesn’t work over there. … but I want a color display. … but I don’t want to buy a new device. … but my device won’t work with the wireless network. … but the buttons are too small.

  8. Technology Comparison Palm OS and PocketPC

  9. Tale of Two Use Cases • Enterprise Digital Assistant – device provided by the institution for clinical use while working at facility. • Personal Digital Assistant – device owned by the clinical end user.

  10. PDAs In The ‘Real World’ Today • Networking • Security • Battery Life • Memory • Cost • Real World Performance • Other Factors

  11. Networking Comparison • Palm OS • Serial (2kB/sec) • Wired Ethernet (3kB/sec) • Infrared (3-6 kB/sec) • 802.11b (7-40kB/sec) • Bluetooth • Cellular WAN • PocketPC • Infrared (9 kB/sec) • 802.11b (20-30 kB/sec) • Cellular WAN

  12. Wireless Standards Comparison

  13. Security Application-Layer Security

  14. Physical Device Security • Size of device (EDA) • Policies & procedures (EDA) • Third party security solutions (EDA / PDA) • Cost of replacing device vs. security solution (EDA)

  15. Battery Life Comparison

  16. Memory Comparison • Palm OS • 8-16MB Typical on older units • 64Mb Tungsten C • Smaller OS, applications • PocketPC • 32-64MB Typical • Larger OS, applications

  17. Real World Performance • Make/Break Items… • Reliable Connectivity • Sync / Load Times • Client Application Performance • Operating System Stability

  18. Cost • Handspring Visor Pro is monochrome • Tungsten C includes 802.11b wireless • Tungsten T included Bluetooth wireless • Compaq iPAQ H3970 includes Bluetooth wireless • HP iPAQ h5450 includes 802.11b AND Bluetooth wireless • Toshiba e740 includes 802.11b wireless

  19. Other Factors • Expandability (SD, CF, Stick, etc.) • User Interface • Other Available Applications for Device

  20. Practical PDA Advice • Pilot all solutions / avoid early mass quantity purchases • Avoid add-on modules as critical components of solution • Where is product within its lifecycle? Future availability? • Is device “certified” and recommended by vendor? • Is wireless hardware “certified” by recognized entities? • http://www.weca.net - Listing of Wi-Fi certified products • Don’t “bet the farm” on any one device, think platform.

  21. Available Medical Software

  22. Handhelds in Production

  23. Handhelds in Production

  24. Success Factors • Recognize and respect limits of current technology • Data delivery, clinical documentation, references today. • Don’t be constrained by limits of current technology • MPOE, medication management, dictation in future. • Identify and leverage existing infrastructure

  25. Technology Adoption Impact Success Factors … but it’s too slow. … but it only works in the hospital. … but what if I lose it? … but the screen is too small. … but the battery doesn’t even last one day. … but I prefer Palm (or PocketPC). … but the wireless network doesn’t work over there. … but I want a color display. … but I don’t want to buy a new device. … but my device won’t work with the wireless network. … but the buttons are too small.
