On October 1, 2017 in Las Vegas, Nevada, the largest mass shooting in US history was committed by a shooter high above the Route 91 Harvest Festival. In light of this tragedy and the increasing incidence and prevalence of mass shootings in America, it is important to examine how exposure to traumatic events (specifically mass shootings) affects the mental health of hospital physicians through the treatment of victims. This study sought to examine how witnessing mass shootings through the treatment of shooting victims psychologically affects physicians. Nine physicians who had direct contact with the victims were interviewed, and the data were analyzed for common themes using phenomenology. From the interviews, five central themes emerged: normalization of the event, denial, feelings of guilt, the positive outcomes associated with the event, and the magnitude of the patient volume. These themes show specifically how physicians are impacted by traumatic events and can be used to implement strategies to promote physician mental health.
