Usage and perceptions of ATHENA Hypertension Decision Support System by primary care physicians

Michel M, Martins SB, Lin N, Kirby A, Hoffman B, Steinman M, Bosworth H, Oddone E, Fischer M, Goldstein MK. Usage and perceptions of ATHENA Hypertension Decision Support System by primary care physicians. Poster session presented at: VA HSR&D National Meeting; 2007 Feb 22; Arlington, VA.


ATHENA-Hypertension, an automated decision support system (DSS), provides patient-specific recommendations to primary care physicians at the point of care. Our study aims were to describe (1) clinician-reported perceptions and use of ATHENA and (2) actual interactions with ATHENA during a 15-month randomized implementation trial. For each visit, data were collected on the type of interaction (e.g., updated ATHENA Advisory, accessed patient history). At trial end, experimental-group clinicians were sent a survey that included questions about usability and navigation of ATHENA. Overall the interaction rate was 52% in the experimental group (10739 interactions / 20524 displayed Advisories) and 16.5% in the controls (3694 interactions / 22301 hypertension reminders) (p < 0.001). From the survey, eighty percent reported good or excellent ease of navigation in finding information (n = 44). Fifty-two percent reported good or excellent integration in their clinical workflow. Providers tend to interact with ATHENA-hypertension and reported high satisfaction with navigation.
