The first two cases of Coronavirus Disease 2019 (COVID-19) were identified in Indonesia on March 2nd, 2020. Health Care workers (HCWs) are at risk of contracting COVID-19 infection. This study analyzed the risk factors, compared the prevalence rate of COVID-19 between HCWs and non-HCWs, and investigated survival analysis describing the time risk of COVID-19.
This prospective cohort study retrieved data from the Hospital Surveillance Team (one of the largest hospitals in West Jakarta) which were analyzed using descriptive, bivariate analysis, Survival Analysis through the Kaplan-Meier method, and multivariate Cox analysis.
Observations were conducted on 1,080 employees from March 2021 to March 2022. There were 192 employees (17.78%) of 40±11 years tested positive for COVID-18, of which 126 cases (16.84%) were HCWs of ≤ 40 years of age, with females dominating. There was no difference between HCW and Non-HCW; ARR=1.08; [95% IK, 0.83-1.43]; p=0.591. Workers on shift work (> 38 hours in a week) were likely to be affected by COVID-19 with RR=1.37; [95% IK, 1.06-1.78]; p=0.018. Kaplan-Meier method and the log-rank test showed the difference between Shift and Non-shift groups HR=1.43; [95% IK 1.06-1.94]; p=0.019. Asthma or Chronic Obstructive Pulmonary Disease appeared as the independent factor of COVID-19 infection with RR=1.82; [95% IK, 1.10-3.02]; p=0.031.
The probability of contracting COVID-19 was found equal to HCW and Non-HCW. Employees who are on shifts have a greater probability of contracting COVID-19. Survival analysis showed a statistically different Hazard Ratio between shifts with Non-shift workers.
2020 年 3 月 2 日，印度尼西亚首次确诊了两例 2019 年冠状病毒病（COVID-19）病例。医护人员（HCWs）有感染 COVID-19 的风险。本研究分析了危险因素，比较了 HCWs 和非 HCWs 之间 COVID-19 的患病率，并调查了描述 COVID-19 时间风险的生存分析。
本前瞻性队列研究从医院监测小组（西雅加达最大的医院之一）中检索数据，使用描述性、双变量分析、通过 Kaplan-Meier 方法进行生存分析和多变量 Cox 分析进行分析。
2021 年 3 月至 2022 年 3 月期间对 1080 名员工进行了观察。共有 192 名（17.78%）年龄为 40±11 岁的员工 COVID-19 检测呈阳性，其中 126 例（16.84%）为≤40 岁的 HCWs，女性居多。HCW 和非 HCW 之间没有差异；ARR=1.08；[95%置信区间，0.83-1.43]；p=0.591。每周轮班工作超过 38 小时的工人更容易受到 COVID-19 的影响，RR=1.37；[95%置信区间，1.06-1.78]；p=0.018。Kaplan-Meier 方法和对数秩检验显示轮班和非轮班组之间的差异 HR=1.43；[95%置信区间，1.06-1.94]；p=0.019。哮喘或慢性阻塞性肺疾病是 COVID-19 感染的独立因素，RR=1.82；[95%置信区间，1.10-3.02]；p=0.031。
感染 COVID-19 的概率与 HCW 和非 HCW 相等。轮班的员工感染 COVID-19 的概率更高。生存分析显示轮班与非轮班工人之间的危险比存在统计学差异。
