Article:

Background and Objectives: Residents have been thrust onto the front lines of the US medical response to COVID-19. This study aimed to quantify and describe the experiences of family medicine residents nationally during the early phases of the pandemic. Specific areas of interest included training received and the residents' personal sense of safety. The purpose of this study was to look for differences among residents based on geographic location. Method: This May 2020 survey was conducted by the Council of Academic Family Medicine Educational Research Alliance (CERA) of a random sample of 5,000 resident members of the American Academy of Family Physicians (AAFP). Results: The overall response rate for the survey was 5.66% (283/5,000). More than 40% of residents reported having felt in moderate to significant personal danger during the COVID-19 pandemic. Fewer than 20% had been tested for COVID-19 themselves. Among all respondents, 176 (65.7%) of the residents had provided direct patient care for COVID-19-positive patients. Most had been trained on personal protective equipment and the medical aspects of COVID-19, but 16.2% reported no training on how to care for COVID-19 patients. Minority residents, and residents in larger urban areas were less likely to receive timely training. Conclusions: The COVID-19 pandemic has had a major impact on family medicine residents' medical education and their sense of safety. Regional variations in residents' educational experiences during the pandemic exist. Training prior to COVID-19 exposure was not universal. In our sample, minority residents were less likely to receive timely training than White residents.
