This study examined the association between lack of compensation for COVID-19-related overtime work (LCCOW) and burnout among emergency medical service (EMS) providers in Seoul, Korea.
We conducted a cross-sectional survey of 693 EMS providers in Seoul, Korea. Participants were classified into 3 groups according to their experience of coronavirus disease 2019 (COVID-19)-related overtime work and LCCOW: (1) "did not experience," (2) "experienced and was compensated," and (3) "experienced and was not compensated." Burnout was measured using the Korean version of the Copenhagen Burnout Inventory, which has 3 subdomains: personal burnout (PB), work-related burnout (WRB), and citizen-related burnout (CRB). Multiple linear regression was applied to examine whether LCCOW was associated with burnout after adjusting for potential confounders.
In total, 74.2% of participants experienced COVID-19-related overtime work, and 14.6% of those who worked overtime experienced LCCOW. COVID-19-related overtime work showed a statistically non-significant association with burnout. However, the association differed by LCCOW. Compared to the "did not experience" group, the "experienced and was not compensated" group was associated with PB (β=10.519; 95% confidence interval [CI], 3.455 to 17.584), WRB (β=10.339; 95% CI, 3.398 to 17.280), and CRB (β=12.290; 95% CI, 6.900 to 17.680), whereas no association was observed for the "experienced and was compensated" group. Furthermore, an analysis restricted to EMS providers who worked overtime due to COVID-19 showed that LCCOW was associated with PB (β=7.970; 95% CI, 1.064 to 14.876), WRB (β=7.276; 95% CI, 0.270 to 14.283), and CRB (β=10.000; 95% CI, 3.435 to 16.565).
This study suggests that LCCOW could be critical in worsening burnout among EMS providers who worked overtime due to COVID-19.
本研究旨在探讨韩国首尔市急救医疗服务（EMS）提供者因 COVID-19 相关加班而未获补偿（LCCOW）与倦怠之间的关联。
我们对韩国首尔市的 693 名 EMS 提供者进行了横断面调查。参与者根据其经历的 2019 年冠状病毒病（COVID-19）相关加班和 LCCOW 情况被分为 3 组：（1）“未经历”，（2）“经历并获得补偿”，和（3）“经历但未获得补偿”。使用韩国版哥本哈根倦怠量表（Copenhagen Burnout Inventory）衡量倦怠，该量表有 3 个亚领域：个人倦怠（PB）、工作相关倦怠（WRB）和公民相关倦怠（CRB）。应用多元线性回归来检验在调整潜在混杂因素后，LCCOW 是否与倦怠相关。
共有 74.2%的参与者经历了 COVID-19 相关加班，其中 14.6%的加班者经历了 LCCOW。COVID-19 相关加班与倦怠之间存在统计学上无显著关联。然而，这种关联因 LCCOW 而异。与“未经历”组相比，“经历但未获得补偿”组与 PB（β=10.519；95%置信区间[CI]，3.455 至 17.584）、WRB（β=10.339；95%CI，3.398 至 17.280）和 CRB（β=12.290；95%CI，6.900 至 17.680）相关，而“经历并获得补偿”组则没有关联。此外，一项仅限于因 COVID-19 而加班的 EMS 提供者的分析表明，LCCOW 与 PB（β=7.970；95%CI，1.064 至 14.876）、WRB（β=7.276；95%CI，0.270 至 14.283）和 CRB（β=10.000；95%CI，3.435 至 16.565）相关。
本研究表明，LCCOW 可能是导致因 COVID-19 而加班的 EMS 提供者倦怠恶化的关键因素。
