  1. PATH: Physician Access to Telemetry from Handhelds David Kreindler, MD, FRCP(C) Nicholas Woolridge, MScBMC

  2. Centre for Mobile Computing in Mental Health • Clinical Base: Sunnybrook Health Science Centre (SHSC) • Investigators: • David Kreindler (Psychiatry) • Charles Lumsden (Medicine/Physics) • Anthony Levitt (Psychiatry) • Nicholas Woolridge (BMC) • Goals: • Clinical implications of handheld computers… • … thereby improving patient quality-of-life

  3. CMCMH: Selected Projects • VMQ/VADIS (2000-2003) • Implemented visual analogue scale on Palm smart phones (tablet and stylus) • Collected twice daily mood symptom ratings on 38 participants for 18 months • MAAC • Animated instrument for mood self-report in children • LifePattern • Companion to VADIS • Displays a self-report ratings on Treo smart phone

  4. Mental Health Telemetry (MHT) • Using wireless handheld computers to transmit symptom information in 'real time' • Typical platform: cell phones • Self-report questionnaire  free-text comments • Links to symptom journaling, 'Ecological momentary assessment', e-diaries / blogs

  5. Mental Health Telemetry (2) • Advantages: • No paper distribution / collection • Portable / prevalent / carried anyway • No data loss <- RT transmission • e-reminders • Time stamped • Better compliance / acceptance • e-questionnaire <-> dynamic medium • e.g. flexible presentation (order; content)

  6. PATH: The Next Logical Step • At present, MHTpatient database • Information retrieved manually / later • PATH: MHTpatient database  clinician • Information retrieved on-demand • Information: timeliness  clinical utility • Hypothesis: Value added by PATH exceeds hassle of using PATH. • I.e., clinicians will find PATH useful, and be willing to use it in routine clinical practice.

  7. PATH: The Next Logical Step

  8. PATH: Methodology • Phase 1: Design (6 months) • Consult with stakeholders, experts, users • Product: Fully functioning prototype (v0.1) • Phase 2: Implementation (12 months) • Three rounds of propose / consult / revise / implement • Product: Final product (v1.0) • Phase 3: Clinical Trial (18 months) • Users: clinicians treating patients with mood & anxiety disorders • Goal: assess usability.

  9. PATH: Role of BMC • Initial design / proof-of-concept sketches • Decision points at months 1, 7, 11, 15 • Software: MHT data stream visualization • User interface design (clinicians) • User interface studies for MHT & PATH
