COVID-19: old age results from SI-VIC, SI-DEP and VAC-SI pairings

## **nota bene: these data were revised following a change in treatment method on 29 October 2021. The new data and the methodological note are available via the links below:** [Revised data](https://data.drees.solidarites-sante.gouv.fr/explore/dataset/covid-19-resultats-par-age-issus-des-appariements-entre-si-vic-si-dep-et-vac-si/information/) [Detailed note on the new methodology](https://drees.solidarites-sante.gouv.fr/communique-de-presse/exploitation-des-appariements-entre-les-bases-si-vic-si-dep-et-vac-si-des) As part of its mission to support the management of the health crisis, the Directorate of Research, Studies, Evaluation and Statistics (DREES) uses pseudonymised data from the three main databases on the Covid-19 crisis: Si-VIC (hospitalisation), SI-DEP (screening) and VAC-SI (vaccination). These farms lead to numerous analyses, published or for use by crisis management actors, on the three themes: screening, hospitalisation and vaccination. DREES also makes crossovers between these bases, in order to shed light on issues that fall under several of these themes in a joint way. Thus, a regular follow-up according to the vaccination status of the number of positive cases in the Covid-19 tests and hospital admissions is carried out. Similarly, comparative analyses of the frequencies of severe Covid-19 cases depending on the variant or identified mutations of the virus affecting patients may be conducted.**请注意：本数据集已于2021年10月29日根据治疗方法变更完成修订。修订后的数据与方法论说明可通过以下链接获取：** [修订后数据](https://data.drees.solidarites-sante.gouv.fr/explore/dataset/covid-19-resultats-par-age-issus-des-appariements-entre-si-vic-si-dep-et-vac-si/information/) [新版方法论详细说明](https://drees.solidarites-sante.gouv.fr/communique-de-presse/exploitation-des-appariements-entre-les-bases-si-vic-si-dep-et-vac-si-des) 为支撑新冠疫情防控管理工作，研究、评估与统计学总局（Directorate of Research, Studies, Evaluation and Statistics，DREES）采用了新冠疫情三大核心数据库的匿名化数据，分别为Si-VIC（住院登记库）、SI-DEP（筛查数据库）与VAC-SI（疫苗接种数据库）。 上述数据集可支撑多项分析工作，相关分析成果已公开或供疫情防控管理主体使用，分析主题涵盖筛查、住院治疗与疫苗接种三大方向。此外，DREES还对这些数据库开展交叉关联分析，以联合阐释同时涉及多个主题的相关问题。 据此，该机构会定期追踪不同疫苗接种状态下的新冠病毒检测阳性人数与住院收治人数。同理，也可针对感染新冠病毒的患者所携带的病毒变异株或已鉴定突变位点，开展重症病例占比的对比分析。
