This study aimed to determine the effect of the presence or absence of avoidable hospitalization before acquiring coronavirus disease (COVID-19) on COVID-19-related deaths. This study used the total NHIS-COVID-19 dataset comprising domestic COVID-19 patients, provided by the National Health Insurance Service (NHIS) in South Korea. We conducted logistic regression and double robust estimation (DRE) to confirm the effect of avoidable hospitalization on COVID-19-related deaths. Logistic regression analysis confirmed that the odds ratio (OR) of death due to COVID-19 was high in the group that experienced avoidable hospitalization. DRE analysis showed a higher OR of death due to COVID-19 in the group that experienced avoidable hospitalization compared to the group that did not experience avoidable hospitalization, except in the subgroup aged ≤69 years. The effect of avoidable hospitalization on COVID-19-related deaths was confirmed. Therefore, continued health care, preventive medicine, and public health management are essential for reducing avoidable hospitalizations despite the COVID-19 pandemic. Clinicians need to be informed about the importance of continuous disease management.
本研究旨在确定在获得冠状病毒病（COVID-19）之前是否存在可避免的住院治疗对 COVID-19 相关死亡的影响。本研究使用了由韩国国家健康保险服务（NHIS）提供的包含国内 COVID-19 患者的总 NHIS-COVID-19 数据集。我们进行了逻辑回归和双重稳健估计（DRE），以确认可避免住院治疗对 COVID-19 相关死亡的影响。逻辑回归分析证实，经历可避免住院治疗的 COVID-19 相关死亡的比值比（OR）较高。DRE 分析显示，与未经历可避免住院治疗的 COVID-19 相关死亡的 OR 相比，经历可避免住院治疗的 COVID-19 相关死亡的 OR 更高，除了年龄≤69 岁的亚组。证实了可避免住院治疗对 COVID-19 相关死亡的影响。因此，尽管存在 COVID-19 大流行，但继续进行医疗保健、预防医学和公共卫生管理对于减少可避免的住院治疗至关重要。临床医生需要了解持续疾病管理的重要性。
