  1. Voice Recognition Efficiency in Internal Medicine Documentation Internal Medicine Noon Conference – 11.24.10 Samuel Ash, MD Resident, Department of Internal Medicine University of Washington Medical Center

  2. Problem • Technology • Experience • Conclusions/Discussion • References • Demonstration • Other Strategies Outline

  3. Saturday call… • 30 hours • 10 patient • 7 admits • 3 forms per admit • Untold number of pages… Problem

  4. An early 20th century transcribing pool at Sears, Roebuck and Co. • Thewomen are using cylinder dictation machines, and listening to the recordings with ear-tubes Technology • (David Morton, the history of Sound Recording History, http://www.recording-history.org/)

  6. Technology

  7. Outpatient Pediatric Specialty Practice • 2 hours of training + 30 “training” notes • 42 “test” notes • Endpoints: time and accuracy Experience

  8. Experience

  9. Experience

  10. Additional Results • 600 new consultations and 1200 repeat visits per year • Average letter/note length 225 words Experience

  11. Advantages • Average turnaround time 1 day vs. 1 week • Disadvantages • 66% less efficient in total time • VRS cost twice as much as traditional transcription (based on attending hourly rate) Experience

  12. Surgical Pathology • Decreased turnaround times (by ~81%) • Decreased error rate (by ~48%) Experience
