Join Dr. Thomas Payne as he describes the development and design of a smartphone app-based system to create inpatient progress notes using voice, commercial automatic speech recognition software, with text processing to recognize spoken voice commands and format the note, and integration with a commercial EHR. The new system fits hospital rounding workflow and was used to support a randomized clinical trial testing whether use of voice to create notes improves timeliness of note availability, note quality, and physician satisfaction with the note creation process. Learn how they created a reliable, accepted by physician users, and secure app and how their approach provided an alternative to use of keyboard and templates to create progress notes and may appeal to physicians who prefer voice to typing.
