Amid the global aging, an establishment of healthcare policies for the aged population is a common issue to be addressed. However, few studies on centenarians have reported place and cause of death (PoD and CoD, respectively) as indicators of end-of-life care quality. This study aimed to analyze trends in PoD and CoD among centenarians in Japan.
Data from death certificates from Japanese vital statistics were analyzed; 205 513 deaths occurred among centenarians (aged ≥100 years) in Japan during the period from 2006 to 2016. PoD prevalence was calculated for each CoD. Trends in PoD prevalence were analyzed using the Joinpoint regression model. Changing points, annual percentage changes, and average annual percentage changes (AAPCs) were calculated to examine trends.
The number of deaths more than doubled from 10 340 in 2006 to 26 427 in 2016. PoDs were composed of hospitals (52.7%), nursing homes (31.4%), own homes (13.6%) and others (2.2%). Dementia and old age increased rapidly as CoD. Proportions of hospital and home deaths decreased, with AAPCs of -2.3% (95% confidence interval [CI], -2.6 to -1.9) and -2.3% (95% CI, -3.2 to -1.4), respectively. Conversely, the proportion of deaths in nursing homes rapidly increased, with an AAPC of 6.8% (95% CI, 6.0-7.7).
The results revealed changes in PoD among centenarians in Japan. Understanding these transitions is indispensable for health policy in aging societies. Geriatr Gerontol Int 2022; 22: 675-680.
在全球老龄化的背景下，为老年人口制定医疗保健政策是一个共同的问题。然而，很少有研究报告百岁老人的死亡地点和原因（分别为 PoD 和 CoD）作为临终关怀质量的指标。本研究旨在分析日本百岁老人的 PoD 和 CoD 趋势。
分析日本人口统计死亡证明数据；2006 年至 2016 年期间，日本有 205513 名百岁老人（年龄≥100 岁）死亡。计算了每个 CoD 的 PoD 患病率。使用 Joinpoint 回归模型分析 PoD 患病率趋势。计算变化点、年变化百分比和平均年变化百分比（AAPC），以检查趋势。
死亡人数从 2006 年的 10340 人增加到 2016 年的 26427 人，增加了一倍多。PoD 由医院（52.7%）、养老院（31.4%）、自己的家（13.6%）和其他地方（2.2%）组成。痴呆症和老年病作为 CoD 迅速增加。医院和家庭死亡的比例下降，AAPC 分别为-2.3%（95%置信区间[CI]，-2.6 至-1.9）和-2.3%（95%CI，-3.2 至-1.4）。相反，养老院的死亡比例迅速增加，AAPC 为 6.8%（95%CI，6.0-7.7）。
结果显示了日本百岁老人 PoD 的变化。了解这些转变对于老龄化社会的卫生政策是必不可少的。老年医学与老年病学杂志 2022；22：675-680。
