The prevalence and associated factors of job burnout among medical workers at COVID-19 vaccination sites: A cross-sectional study

Abstract

Background Medical workers at COVID-19 vaccination sites are exposed to burnout syndrome due to repetitive and overload vaccination work. The purpose of our study was to investigate the prevalence of burnout among these medical workers and to explore its associated factors. Methods A cross-sectional study was conducted at COVID-19 vaccination sites in May 2021 in Nanjing, China. The online questionnaire included demographic, job and COVID-19 related characteristics, Chinese Maslach Burnout Inventory, and Social Support Rating Scale. Hierarchical multiple regression model was used to identify the risk factors for job burnout of medical workers. Results The overall prevalence of burnout symptoms among medical workers at COVID-19 vaccination sites was 44.5% with a breakdown in severity as follows: 122 (28.7%) mild, 53 (12.5%) moderate, and 14 (3.3%) severe cases. Hierarchical multiple linear regression analysis indicated that education level, health condition, job titles, self-reported increased work intensity, monthly income and social support were significantly related to job burnout (p < 0.05), which explained 37.6% of the variance of job burnout score (F = 16.046, p < 0.01). Conclusion The burnout symptoms were relatively common among medical workers at COVID-19 vaccination sites. More attention should be paid to medical workers with master degree or higher, poor health condition, junior or middle job titles, increased work intensity, lower income and low level of social support. Interventions that aim to reduce workload and increase social support can be effective approaches to prevent job burnout among medical workers during controlled COVID-19 period.
