Abstract

Background: The case fatality rate (CFR) is one of the most important measures for monitoring disease progression and evaluating appropriate policy health measures over the course of the COVID-19 pandemic. To remove biases arising from the age structure of COVID-19 cases in international comparisons of the CFR, existing studies have relied mainly on direct standardisation.

Objective: We propose and validate a synthetic indicator of COVID-19 fatality (SCFR) that improves its comparability across countries by adjusting for the age and sex structure of COVID-19 cases without relying on the arbitrary choice of a standard population.

Results: Contrary to what comparisons of the crude CFR suggest, differences in COVID-19 fatality across countries according to the proposed SCFR are not very stark. Importantly, once we adjust for the age structure of COVID-19 cases, the higher case fatality among men emerges as the main driver of international differences in COVID-19 CFR.

Conclusions: The SCFR is a simple indicator that is useful for monitoring the fatality of SARS-CoV-2 mutations and the efficacy of health policy measures for COVID-19, including vaccination.

Contributions: (1) A simple synthetic indicator of COVID-19 fatality that improves its comparability across countries by adjusting for the age and sex structure of COVID-19 cases; (2) Evidence that sex differences in COVID-19 fatality drive international differences in the overall CFR.

比较各国COVID-19死亡率:一个综合人口指标。
背景:病死率(CFR)是监测COVID-19大流行期间疾病进展和评估适当卫生政策措施的最重要指标之一。为了消除国际比较中COVID-19病例年龄结构产生的偏差,现有研究主要依赖于直接标准化。目的:我们提出并验证了一种COVID-19病死率(SCFR)的综合指标,该指标通过调整COVID-19病例的年龄和性别结构来提高其在各国之间的可比性,而不依赖于任意选择标准人群。结果:与粗CFR的比较结果相反,根据拟议的SCFR,各国COVID-19死亡率的差异并不十分明显。重要的是,一旦我们根据COVID-19病例的年龄结构进行调整,男性较高的病死率就会成为COVID-19 CFR国际差异的主要驱动因素。结论:SCFR是一项简单的指标,可用于监测SARS-CoV-2突变的致死率和COVID-19卫生政策措施(包括疫苗接种)的效果。贡献:(1)通过调整COVID-19病例的年龄和性别结构,建立了COVID-19病死率的简单综合指标,提高了其在各国之间的可比性;(2) COVID-19病死率的性别差异导致总体CFR的国际差异的证据。
