Abstract: Objectives To determine the prevalence of burnout according to job category after the first wave of COVID-19 in Japan and to explore its association with certain factors. Methods An online cross-sectional survey of health care workers (HCWs) from June 15 to July 6, 2020, was conducted at a tertiary hospital in Tokyo, Japan. Demographic characteristics, results of the Japanese version of the Maslach Burnout Inventory-General Survey, types of anxiety and stress, changes in life and work after the peak of the pandemic, and types of support aimed at reducing the physical or mental burden, were determined. Results Of 672 HCWs, 149 (22.6%) met the overall burnout criteria. Burnout was more prevalent in women (OR, 3.11; 95% CI, 1.45-6.67, P = .003), anxiety due to unfamiliarity with personal protective equipment (PPE) (OR, 1.98; 95% CI, 1.20-3.27, P = .007), and decreased sleep duration (OR, 1.96; 95% CI, 1.20-3.20, P = .008). Conversely, participants who felt that the delivery of COVID-19-related information (OR, .608; 95% CI, .371-.996, P = .048) and PPE education opportunities (OR, .484; 95% CI, .236-.993, P = .048) and messages of encouragement at the workplace (OR, .584; 95% CI, .352-.969; p = .037) was helpful experienced less burnout. Conclusions There is a need to focus on the above factors to maintain the mental health of HCWs. The delivery of COVID-19-related information and educational interventions for PPE and messages of encouragement at the workplace may be needed to reduce the mental burden.
