Ten-year trends in end-of-life hospitalizations of nursing home residents in Germany, 2006-2015

Objectives: We investigated trends in end-of-life hospitalizations among nursing home residents (NHR) over 10 years and looked at differences between age groups and sexes as well as the length of terminal hospital stays. Study design: Retrospective cohort study based on health insurance claims data of the AOK Bremen/Bremerhaven. All NHR aged 65 years or more who died between 2006 and 2015 were included. Main outcome measures: We assessed the proportions of decedents who were in hospital on the day of death and during the last 3, 7, 14 and 30 days of life, stratified by two-year periods. Multiple logistic regressions were conducted to study changes over time, adjusting for covariates. Results: A total of 10,781 decedents were included (mean age 86.1 years, 72.1 % females). Overall, 29.2 % died in hospital, with a slight decrease from 30.3 % in 2006-2007 to 28.3 % in 2014-2015 (OR 0.86; 95 % CI 0.75-0.98). Of the 3150 terminal hospitalizations, 35.5 % lasted up to 3 days and the mean length of stay decreased from 9.0 (2006-2007) to 7.5 days (2014-2015). When looking at the last 7, 14 and 30 days of life, no changes over time were found. Male sex and younger age were associated with a higher chance of end-of-life hospitalization in almost all analyses. Conclusions: End-of-life hospitalizations of NHR are common in Germany. There has been a small decrease during recent years in the proportion of in-hospital deaths, but not of hospitalizations during the last 7, 14 and 30 days of life. This might be explained by shorter durations of hospital stays.
