Burnout and turnover risks for healthcare workers in the United States: downstream effects from moral injury exposure

Moral injury has emerged as a construct of interest in healthcare workers' (HCW) occupational stress and health. We conducted one of the first multidisciplinary, longitudinal studies evaluating the relationship between exposure to potentially morally injurious events (PMIEs), burnout, and turnover intentions. HCWs (N = 473) completed surveys in May of 2020 (T1) and again in May of 2021 (T2). Generalized Linear Models (robust Poisson regression) were used to test relative risk of turnover intentions, and burnout at T2 associated with PMIE exposure, controlling for T1 covariates. At T1, 17.67% reported they had participated in a PMIE, 41.44% reported they witnessed a PMIE and 76.61% reported feeling betrayed by healthcare or a public health organization. In models including all T1 PMIE exposures and covariates, T2 turnover intentions were increased for those who witnessed a PMIE at T1 (Relative Risk [RR] = 1.66, 95% Confidence Interval [CI] 1.17-2.34) but not those that participated or felt betrayed. T2 burnout was increased for those who participated in PMIE at T1 (RR = 1.38, 95%CI 1.03-1.85) but not those that witnessed or felt betrayed. PMIE exposure is highly prevalent among HCWs, with specific PMIEs associated with turnover intentions and burnout. Organizational interventions to reduce and facilitate recovery from moral injury should account for differences in the type of PMIE exposures that occur in healthcare work environments.
