Background: Germany has more intensive care unit (ICU) beds per capita than the USA, but the utilization of these resources at the end of life is unknown.
Methods: Retrospective observational study using nationwide German hospital discharge data (DRG statistics; DRG, diag- nosis-related groups) from 2007 to 2015. We investigated hospital deaths and use of intensive care services during terminal hospitalizations. Population-based incidences were standardized to the age and sex distribution of the German population.
Results: Standardized hospital admission rates increased by 0.8% annually (from 201.9 to 214.6 per 1000 population), while hospital admissions involving ICU care increased by 3.0% annually (from 6.5 to 8.2 per 1000 population). Among all deaths in the German population, the proportion of hospital deaths with ICU care increased by 2.3% annually (from 9.8% to 11.8%). Among all hospital deaths, the proportion involving ICU care increased by 2.8% annually from 20.6% (2007) to 25.6% (2015). In patients aged 65 and older, the use of intensive care services during terminal hospitalizations increased 3 times faster than hospital deaths.
Conclusion: Use of intensive care services during terminal hospitalizations increased across all age groups, particularly the elderly. The increased need for end-of-life care in the ICU calls for improvements in educational, policy, and reimbursement strategies. It is unclear whether ICU care was appropriate and compliant with patient preferences.
