This document discusses the ethical challenges that arise when healthcare professionals and trainees transition from clinical settings to community-based participatory research (CBPR) partnerships. It uses a case study of a partnership between a veteran's nonprofit, academics, and a VA medical center to illustrate the tensions between professional ethics focused on rules and consequences versus community ethics focused on the common good. The authors argue that explicitly considering virtue ethics can help balance these divergent perspectives by emphasizing human flourishing over institutional concerns. Training professionals to navigate these discontinuities in ethical assumptions is important for collaborative community work.
