“Communicating with Patients on Health Care Evidence,” presents tested messages and insights for engaging effectively with patients on medical evidence. Developed by individual participants from the IOM’s Evidence Communication Innovation Collaborative, the authors surveyed the landscape of existing efforts to communicate evidence effectively and then fielded focus groups and a nationally representative survey. The authors’ research revealed that patients want to be deeply engaged in decisions about their health, but current conversations with their clinicians fall short. Furthermore, patients believe that evidence is at least as important as their clinician’s expertise and their own preferences when making health care decisions. In its conclusion, the discussion paper notes action areas to promote improved health care decision-making — culture change, incentives alignment, infrastructure support, quality standards, and accountability.
