Quantifying the combined impact of morbidity and mortality is a key enabler to assessing the impact of COVID-19 across countries and within countries relative to other diseases, regions, or demographics. Differences in methods, data sources, and definitions of mortality due to COVID-19 may hamper comparisons. We describe efforts to support countries in estimating the national-level burden of COVID-19 using disability-adjusted life years.
The European Burden of Disease Network developed a consensus methodology, as well as a range of capacity-building activities to support burden of COVID-19 studies. These activities have supported 11 national studies so far, with study periods between January 2020 and December 2021.
National studies dealt with various data gaps and different assumptions were made to face knowledge gaps. Still, they delivered broadly comparable results that allow for interpretation of consistencies, as well as differences in the quantified direct health impact of the pandemic.
Harmonized efforts and methodologies have allowed for comparable estimates and communication of results. Future studies should evaluate the impact of interventions, and unravel the indirect health impact of the COVID-19 crisis.
量化发病率和死亡率的综合影响是评估 COVID-19 在国家间和国家内相对于其他疾病、地区或人口的影响的关键手段。由于 COVID-19 导致的死亡率在方法、数据源和定义方面的差异可能会阻碍比较。我们描述了使用伤残调整生命年来支持各国估算 COVID-19 国家层面负担的努力。
欧洲疾病负担网络制定了一项共识方法以及一系列能力建设活动，以支持 COVID-19 研究的负担。这些活动迄今为止已支持了 11 项国家研究，研究期间为 2020 年 1 月至 2021 年 12 月。
国家研究解决了各种数据差距，并针对知识差距做出了不同的假设。尽管如此，它们提供了广泛可比的结果，允许解释一致性，以及大流行对直接健康影响的量化差异。
协调一致的努力和方法允许进行可比的估算和结果交流。未来的研究应评估干预措施的影响，并揭示 COVID-19 危机的间接健康影响。
