Background Health care professionals report higher levels of mental health symptoms, pandemic-related stress, personal health concerns, and reduced proactive coping, especially in recent years marked by the COVID-19 pandemic. As physician utilization rates of mental health and well-being services remain low, the need for preemptive care is crucial. Objective The present study sought to ascertain satisfaction, value, and attitude toward future mental health services among resident physicians. Methods Throughout the 2020-2021 academic year, resident physicians within 8 training programs at a large academic training hospital were offered single opt-out mental health appointments from hospital-funded, graduate medical education wellness staff at no cost to the resident. Appointments were conducted virtually during protected work time. A survey was sent to participants within 2 weeks following their appointment. Results A total of 153 residents (postgraduate years 1 to 7) were offered one-time opt-out appointments. Overall, 91 (59%) residents attended their opt-out appointments. Survey response rate was 57% (n=52). Respondents reported high levels of satisfaction (96%, 50 of 52), felt the appointment was worth their time (96%, 50 of 52), and felt that the opt-out appointments demonstrated training programs cared about their well-being (94%, 49 of 52). Nearly all residents (98%, 51 of 52) recommended appointments be offered to future residents. Most respondents (80%, 42 of 52) indicated that appointments increased their willingness to engage in mental health services. Conclusions Opt-out appointments increased resident willingness to engage in mental health services, positive attitudes toward future mental health services, perceived training program's care about their well-being, and reduced perceived mental illness stigma.
