The Institute of Medicine has a 2011 publication that I thought was fascinating– Patient-Clinician Communication: Basic Principles and Expectations (PDF). I love the rationale for specifically looking at this issue:
“Consistent and effective communication between patient and clinician has been associated in studies not only with improved patient satisfaction and safety, but also ultimately with better health outcomes, and often with lower costs. Breakdowns of communication, or disregard for patient understanding, context, and preferences, have been cited as contributors to health care disparities and other counterproductive variations in health care utilization rates. Moreover, professional ethics in health care stress the intrinsic importance of respectful and effective communication as a core aspect of informed consent and a trusting relationship.” (p. 1, emphasis mine)
