Place and Cause of Death in Centenarians: A Population- Based Observational Study in England, 2001 to 2010

Background: Centenarians are a rapidly growing demographic group worldwide, yet their health and social care needs are seldom considered. This study aims to examine trends in place of death and associations for centenarians in England over 10 years to consider policy implications of extreme longevity. Methods and Findings: This is a population-based observational study using death registration data linked with area-level indices of multiple deprivations for people aged$100 years who died 2001 to 2010 in England, compared with those dying at ages 80-99. We used linear regression to examine the time trends in number of deaths and place of death, and Poisson regression to evaluate factors associated with centenarians ’ place of death. The cohort totalled 35,867 people with a median age at death of 101 years (range: 100–115 years). Centenarian deaths increased 56 % (95 % CI 53.8%–57.4%) in 10 years. Most died in a care home with (26.7%, 95 % CI 26.3%–27.2%) or without nursing (34.5%, 95 % CI 34.0%–35.0%) or in hospital (27.2%, 95 % CI 26.7%–27.6%). The proportion of deaths in nursing homes decreased over 10 years (20.36 % annually, 95% CI 20.63 % to 20.09%, p = 0.014), while hospital deaths changed little (0.25 % annually, 95 % CI 20.06 % to 0.57%, p = 0.09). Dying with frailty was common with ‘‘old age’ ’ stated in 75.6 % of death certifications. Centenarians were more likely to die of pneumonia (e.g., 17.7 % [95 % CI 17.3%–18.1%] versus 6.0 % [5.9%–6.0%] for those aged 80–84 years) and old age/frailty (28.1 % [27.6%–28.5%] versus 0.9 % [0.9%–0.9%] for those aged 80–84 years) and less likely to die of cancer (4.4 % [4.2%
