In accordance with standards published by the American Society for Bioethics and Humanities (ASBH), ethics consultants are expected to provide recommendations that align with scholarly literature, professional society statements, law, and policy. However, there are no studies to date that characterize the specific references that ethics consultants and educators use to inform their work. To address this gap, a convenience sample of clinical ethics consultants and educators was surveyed online through two major listservs for clinical ethics, the ASBH Clinical Ethics (...) Consultation Affinity Group (CECAG) and the Association of Bioethics Program Directors (ABPD). Ninety-five ethics consultants and/or educators with diverse educational background, credentials, and experience provided responses. In total, 451 references, 315 of which were unique, were reported. These references were broken into 6 categories after analysis: bioethics literature (divided into articles and books), professional society documents (divided into professional society statements and codes of ethics), federal/state/uniform/case law, hospital/health system policies, official religious teachings, and other. We found extensive variation and minimal overlap in the references respondents used for ethics consultation and education, even when referring to the same topics. Future research directions should include conducting more systematic efforts to characterize the references used by ethics consultants across the US; determining whether demographic characteristics of consultants influence the references used; and ascertaining whether the variation in references used reflects genuine disagreements in consultants’ and educators’ bioethical analysis or recommendations.
