Burnout is a well-recognized problem among resident physicians. The COVID-19 pandemic impacted the dynamics of the patient/resident relationship and introduced new stressors for medical trainees, such as new restrictions in the hospital, increased patient death, and uncertainty around safety. There is limited research on the implementation of group therapy for residents to address issues of wellbeing and burnout during the pandemic. In response to perceived burnout amongst internal medicine residents, a university-based internal medicine residency program in the Northeast United States implemented process groups, a form of group therapy, in the curriculum. These sessions were held hourly once every five weeks for each cohort of twelve residents during the academic year. We sought to measure resident burnout and identify themes that impacted wellbeing to facilitate the intervention of process groups during the pandemic. In 2021 and 2022, internal medicine residents were invited to complete the Maslach Burnout Inventory (MBI) and answer two open-ended questions about the factors that most negatively and positively influenced their wellness. Of the 134 participants, 82% had high emotional exhaustion or depersonalization. The most prevalent themes hindering wellness were negative personal interactions at work, most notably rude behavior by patients, unsupportive attendings, residency program expectations, and work intensity. Findings unique to the pandemic include social isolation from family, distress from poor outcomes, and fear of contracting or spreading the virus. The most prevalent themes for supporting wellness were personal life, camaraderie, professional satisfaction, and program structured support. Our findings suggest that programs can tailor structured support to improve wellness, despite the presence of significant stressors.
