Abstract

Although the number of centenarians is increasing rapidly in many countries around the world,1 there is evidence of lower morbidity among centenarians (100+ years of age) and supercentenarians (110+ years)2,3 and more extended stays in long-term care facilities (LTCFs) than in younger cohorts of oldest-old.4 Although evidence is still sparse, hints exist on protective effects in centenarians during the COVID-19 pandemic.5,6 In contrast, a study of excess mortality rates in centenarians who lived in LTCF in the Lombardy region, Italy, found no survival advantage of centenarians compared to those aged 50 and 80 years.7 However, this study only looked into all-cause mortality without information on COVID-19. Men seem to be particularly resilient, which could be due to stronger selection effects., 1.36-2.04). Hospital-related claims data by a major health and long-term care insurance fund in Germany during 3 waves of the pandemic (January 2020 until June 2021) have been analyzed. COVID-19–relevant hospital admissions were assessed by a confirmed COVID-19 diagnosis (ICD U07.1) and COVID-19–relevant primary diagnosis.
