Many studies have evaluated factors that influence the course of the COVID-19 pandemic in different countries. This multicountry study assessed the influence of democracy and other factors on the case fatality rate of COVID-19 during the early stage of the pandemic. We accessed the World Health Organization, World Bank, and the Democracy Index 2019 databases for data from the 148 countries. Multiple analyses were conducted to examine the association between the Democracy Index and case fatality rate of COVID-19. Within 148 countries, the percentage of the population aged 65 years and above (p = 0.0193), and health expenditure as a percentage of GDP (p = 0.0237) were positively associated with countries' case fatality rates. By contrast, hospital beds per capita helped to reduce the case fatality rates. In particular, the Democracy Index was positively associated with case fatality rates in a subgroup of 47 high-income countries. This study suggests that enhancing the health system with increased hospital beds and healthcare workforce per capita should reduce case fatality rate. The findings suggest that a higher Democracy Index is associated with more deaths from COVID-19 at the early stage of the pandemic, possibly due to the decreased ability of the government.
许多研究评估了不同国家 COVID-19 大流行进程的影响因素。这项多国家研究评估了民主和其他因素对大流行早期 COVID-19 病死率的影响。我们从世界卫生组织、世界银行和 2019 年民主指数数据库获取了来自 148 个国家的数据。进行了多项分析来检验民主指数与 COVID-19 病死率之间的关联。在 148 个国家中,65 岁及以上人口比例(p=0.0193)和卫生支出占国内生产总值的比例(p=0.0237)与国家病死率呈正相关。相比之下,人均医院床位有助于降低病死率。特别是,民主指数与 47 个高收入国家亚组的病死率呈正相关。本研究表明,通过增加人均医院床位和医疗保健人员数量来加强卫生系统,应能降低病死率。研究结果表明,在大流行早期,较高的民主指数与 COVID-19 死亡人数增加有关,这可能是由于政府的应对能力下降所致。
