Usage and perception of ATHENA-Hypertension DSS by primary care clinicians

Michel M, Martins SB, Chan A, Lin N, Goldstein MK. Usage and perception of ATHENA-Hypertension DSS by primary care clinicians. Presented at: National Library of Medicine Informatics Training Course; 2007 Jun 27; Palo Alto, CA.


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.
