Abstract:
The purposes of the study were to examine critical usability issues in AHLTA; redesign problematic features and test the new functions; and, using this knowledge, design and evaluate automated clinical practice guidelines (aCPGs) in AHLTA. Usability issues were examined using naturalistic observations and structured interviews. The naturalistic observations were done in two clinics, Family Practice and Pediatrics, and involved six physicians during nine patient encounters. The 12 clinicians who were interviewed walked the interviewer through their daily routines related to using AHLTA. Their verbal responses were audio-taped. Their use of AHLTA was captured on videotape, with the camera focused solely on the computer screen. These data were analyzed by staff from Pacific Science and Engineering. Over 175 usability issues were identified. The plans to redesign and test AHLTA and design and evaluate aCPGs were thwarted by operational issues. In particular, it was not possible to collect data using future releases of AHLTA that were under development. Despite months of effort to devise a feasible alternative, the only reasonable solution was to modify the original Scope of Work and address new research aims.
