Technology induced error and usability: the relationship between usability problems and prescription errors when using a handheld application.

摘要: This paper describes an innovative approach to the evaluation of a handheld prescription writing application. Participants (10 physicians) were asked perform series tasks involving entering prescriptions into application from medication list. The study procedure involved collection data consisting transcripts subjects who "think aloud" while interacting with program enter medications. All user interactions device video and audio recorded. Analysis protocols was conducted in two phases: (1) usability problems identified coding data, (2) actual errors also identified. results indicated that there variety problems, most related interface design issues. In examining relationship between errors, it found certain types closely associated occurrence specific Implications for identifying predicting technology-induced error are discussed context improving safety health care information systems.
