Background:Studies that comprehensively address the characteristics of centenarian deaths are *** present study aimed to depict the characteristics of centenarian deaths in China and their changing ***:Data on centenarian deaths between 2013 and 2020 were obtained from the national mortality surveillance system of China,including date,place of death(PoD),and underlying cause of death(CoD).Descriptive analyses were performed to understand the epidemiological characteristics,and a joinpoint regression model was adopted to examine the changing trends in the proportions of different PoDs,CoDs among centenarians,and centenarian deaths accounting for all deaths and deaths among people aged 65 years and ***:There were 46,938 registered centenarian deaths between 2013 and 2020 that included 34,311 females(73.10%)and 12,627 males(26.90%).January(12.05%),February(9.99%),and December(9.74%)were the top three months with the highest number of *** proportions of deaths that occurred in homes,hospitals,and nursing homes were 81.71%,13.63%,and 2.68%,*** proportion of deaths in nursing homes increased by 9.60%(95%confidence intervals[CIs],6.4-12.9%)from 2014 to *** disease(35.72%)was the leading cause of death,followed by respiratory diseases(17.63%),cerebrovascular disease(15.60%),and old age(11.22%).The proportion of respiratory diseases decreased by 4.8%(95%CI,-8.8 to-0.7%),and the proportion of deaths from old age decreased by 2.3%(95%CI,-4.4 to-0.1%)per *** had the highest proportions of deaths in hospitals(39.38%)and nursing homes(14.68%).Sichuan had the highest proportion of deaths attributed to respiratory diseases(32.30%),while Jiangsu(26.58%)and Zhejiang(23.61%)had the highest proportions of deaths from old ***:Unlike other countries,centenarian deaths in China are characterized by a higher proportion of home and heart disease deaths,and this death pattern differs across provinces.

Real-world study(RWS)gained prominence starting with a significant investigation on ramipril’s impact on hypertension in 1993(1).A key advancement for the Food and Drug Administration(FDA)occurred with the enactment of the 21st Century Cures Act in 2016,emphasizing RWS(2).The FDA’s Real-world Evidence program establishes real-world data(RWD)as“data relating to patient health status and/or the delivery of health care routinely collected from a variety of sources”,while real-world evidence(RWE)is“clinical evidence about the usage and potential benefits or risks of a medical product derived from analysis of RWD”(3).The proliferation of big data,electronic medical records(EMR),electronic health records(EHR),and medical claims data offers vast information resources facilitating *** access to RWD allows for worldwide monitoring of the impacts of various public health initiatives like vaccination *** randomized clinical trials(RCTs)traditionally gauge vaccine efficacy and shortterm safety,RWS can assess vaccine performance and safety across larger,more diverse populations and are adept at identifying rare events not easily discernible in RCTs due to their infrequency.
