BACKGROUND
Older adults living in nursing homes (NH) paid a heavy price to the COVID-19 pandemic, despite early and often drastic prevention measures.
AIMS
To study the characteristics and the impact of the pandemic on NH residents and professionals over 2 years.
METHODS
Cross-sectional study of COVID-19 clusters among residents and/or professionals in NH, from March 2020 to February 2022, in Normandy, France. We used data from the French mandatory reporting system, and cross-correlation analysis.
RESULTS
The weekly proportion of NH with clusters was strongly correlated with population incidence (r > 0.70). Attack rates among residents and professionals were significantly lower in period 2 (vaccination rate in residents ≥ 50%) compared with periods 1 (waves 1 and 2) and 3 (Omicron variant ≥ 50%). Among residents, mortality and case fatality rates decreased drastically during periods 2 and 3.
CONCLUSION
Our study provides figures on the evolution of the pandemic in NH.
背景
尽管采取了早期且往往非常严厉的预防措施，居住在养老院（NH）的老年人还是为 COVID-19 大流行付出了沉重的代价。
目的
研究 COVID-19 对 NH 居民和专业人员在 2 年期间的特征和影响。
方法
2020 年 3 月至 2022 年 2 月，在法国诺曼底对 NH 中居民和/或专业人员中的 COVID-19 集群进行了一项横断面研究。我们使用了法国强制性报告系统的数据和交叉相关分析。
结果
每周 NH 集群的比例与人群发病率呈强相关（r > 0.70）。与第 1 期（第 1 波和第 2 波）和第 3 期（Omicron 变体≥50%）相比，第 2 期（居民疫苗接种率≥50%）中居民和专业人员的攻击率明显较低。在居民中，死亡率和病死率在第 2 期和第 3 期急剧下降。
结论
我们的研究提供了 NH 中 COVID-19 流行演变的数字。
