Dynamics of Physicians' Trust in Fellow Health Care Providers and the Role of Health Information Technology.

Physicians are expected and incentivized to coordinate patient care with other providers, including nonphysician clinician (NPC) members of care teams, requiring trust. Trust in the context of care teams has not been well-studied; even less is known about how health information technologies (HIT) may modify trust in these relationships. We conducted semistructured interviews with 30 physicians at a Midwestern academic center to examine how physicians determine they can trust NPCs, and how technology modifies these relationships. A majority of physicians base trust in NPCs on cognitive factors such as competence and reliability. Technology enhances trust between physicians and NPCs by supporting evidence-based decision making; it can also erode trust by limiting opportunities for developing familiarity and comfort with fellow providers. Our work has implications for enhancing HIT to promote trust between providers, and for developing more robust measures of trust that can be used in evaluating and improving teamwork within practices.
