Evaluation of quality indicators near death in older adult cancer decedents in Japan: A nationwide retrospective cohort study.

OBJECTIVES: End-of-life cancer care is important; however, data on hospitalization and costs for older patients have been lacking. We aimed to examine quality indicators and costs for older patients in Japan. METHODS: Using the Diagnosis Procedure Combination database, a national database of acute-care hospitals in Japan, we retrospectively collected data on cancer decedents aged ≥65 years. We evaluated the quality indicators (hospitalizations, length of stay in the hospital, emergency hospitalizations, emergency hospitalizations using an ambulance, intensive care unit [ICU] admissions, length of stay in the ICU, interval between last chemotherapy use and death, and chemotherapy within 14 days before death) and hospitalization costs at 30, 90 and 180 days before death. We compared the outcomes across age groups (65-74, 75-84 and ≥ 85 years). RESULTS: Between January 2011 and March 2015, we identified 369 616 cancer decedents. From 180 to 30 days before death, there were increases in emergency hospitalizations, emergency hospitalizations using an ambulance, and the mean costs per hospital day. Overall, 16.7% of patients receiving chemotherapy last received this treatment on the day before death or the day of death. Costs decreased with increasing age. The group aged ≥85 years had the shortest hospital and ICU stays and the lowest multiple hospitalizations, ICU admissions, chemotherapy within 14 days before death, and costs. CONCLUSIONS: Many older adult patients had emergency hospitalizations and received chemotherapy just prior to death, and there is room for improvement in appropriate end-of-life care. Oldest old patients consumed relatively few medical resources.
