Formative evaluation of a patient-specific clinical knowledge summarization tool
We designed and evaluated a clinical decision support tool (Clinical Knowledge Summary) that automatically summarizes patient-specific clinical evidence to help clinicians decision making. We followed an iterative, user-centered design, guided by information foraging theory and information visualization principles and informed by observations of target users interacting with high-fidelity prototypes. The resulting tool consists of an interactive clinical evidence browser that presents users with a set of clinically actionable recommendations extracted from relevant documents in UpToDate and high quality clinical studies in PubMed. Physicians successfully completed most of the usability tasks in a short period of time. Physicians perceived decision quality was significantly higher with the Clinical Knowledge Summary compared with manual search, but no difference was found in information seeking time.
