Adverse events that occur in healthcare settings may have serious negative implications for patients, families, health care providers, and healthcare organizations. There is a need for strong leadership to prevent and mitigate the damaging effects of adverse events. Authentic leaders have been shown to enhance interprofessional collaboration among healthcare providers and reduce the frequency of adverse events. The purpose of this study was to test the relationships among authentic leadership, interprofessional collaboration, and nurse assessed adverse events in a mediation model. A secondary analysis of 269 experienced registered nurses randomly selected from three provinces (Alberta, Nova Scotia, and Ontario) were included. A predictive non-experimental study design was used. Hayes’ PROCESS version 3 SPSS macro for mediation analysis was used to test the hypothesized path model. There was a negative association between authentic leadership and nurse assessed adverse events via the indirect effect of interprofessional collaboration (B= -.034, 95% CI [-.069, -.004]). Furthermore, the mediation model accounted for 8% of the variance seen within nurse assessed adverse events. Study findings highlight the importance of healthcare leaders in advancing the patient safety agenda.
