Top factors driving burnout included time (eg, increased work hours, time constraints), extra duties (clinical and administrative), and perceived lack of radiology knowledge when dealing with complex cases. Interventions included additional daily 1-hour teaching sessions, wellness lunch rounds, debriefing sessions, transitioning from paper-based protocolling to a hybrid-electronic paper-based system, call schedule modifications, improved ergonomics, and social functions, including incorporating indoor and outdoor activities.
