Purpose: The coronavirus disease 2019 (COVID-19) pandemic caused by SARS-CoV-2 (severe acute respiratory disorder 2) has emerged as the primary global health concern of 2020 . Oral and maxillofacial surgery (OMS) residents, like other health care personnel, have been on the front line providing care to SARS-CoV-2-negative and SARS-CoV-2-positive patients across the United States . As surgeons of the head and neck, OMS residents may be at an increased risk of infection; however, little is known about the prevalence of SARS-CoV-2 infection among OMS residents across the United States . This research study sought to elucidate the prevalence of SARS-CoV-2 infection among OMS residents and explore the risk factors that are associated with infection .
Methods: Institutional review board approval for the study was obtained via NYU School of Medicine . The study was performed via the dissemination of a secure electronic survey to OMS residents in accredited training programs across the United States . The survey elicited information regarding residency training, demographic characteristics, health characteristics, and SARS-CoV-2 testing . Survey data were collected between August 20 , 2020, and September 21 , 2020, and the data were subsequently exported to SAS 9.4 for statistical analysis . Prevalence with 95% confidence intervals was calculated with the exact binomial technique . Categorical variables were compared using Fisher's exact test, and continuous variables were compared with the Mann Whitney U test .
Results: One hundred twenty-nine survey respondents initiated the survey, and 84 respondents completed the survey . Respondents who failed to complete the survey were excluded from the study . Of the 84 respondents who completed the survey, 47 respondents indicated that they had received a SARS-CoV-2 PCR (polymerase chain reaction), antigen, or serology test . Five of the 47 respondents reported a positive result, which revealed a prevalence of 10.64 (95% confidence interval , 3.55-23.1). The presence of symptoms was significantly associated with a report of a positive test result . Respondents who reported symptoms were 20 times more likely to report a positive test result than respondents who reported no symptoms (P = .008). Conclusion: In conclusion, this study found that the prevalence of SARS-CoV-2 infection among OMS residents across the United States is approximately 10.64% and the presence of symptoms is associated with a positive test result . Even though the United States has been managing the COVID-19 pandemic for close to 1 year, it is important that OMS residents continue to adhere to infection control measures and self-monitor for the presence of symptoms consistent with SARS-CoV-2 infection.
