ABSTRACT: This study examined the prevalence and predictors of moral injury (MI) symptoms in 181 health care professionals (HPs; 71% physicians) recruited from Duke University Health Systems in Durham, NC. Participants completed an online questionnaire between November 13, 2019, and March 12, 2020. Sociodemographic, clinical, religious, depression/anxiety, and clinician burnout were examined as predictors of MI symptoms, assessed by the Moral Injury Symptoms Scale-Health Professional, in bivariate and stepwise multivariate analyses. The prevalence of MI symptoms causing at least moderate functional impairment was 23.9%. Younger age, shorter time in practice, committing medical errors, greater depressive or anxiety symptoms, greater clinician burnout, no religious affiliation, and lower religiosity correlated with MI symptoms in bivariate analyses. Independent predictors in multivariate analyses were the commission of medical errors in the past month, lower religiosity, and, especially, severity of clinician burnout. Functionally limiting MI symptoms are present in a significant proportion of HPs and are associated with medical errors and clinician burnout.
