Aggressive End-of-Life Treatments Among Inpatients With Cancer and Non-cancer Diseases Using a Japanese National Claims Database

To describe aggressive treatments at end-of-life among inpatients with cancer and non-cancer diseases and to evaluate factors associated with these treatments using the Japanese national database (NDB). We conducted a retrospective cohort study among inpatients aged >= 20 years who died between 2012 and 2015 using a sampling dataset of NDB. The outcome was the proportion of aggressive treatments in the last 14 days of life. We considered the underlying causes of death as cancer, dementia/senility, and heart, cerebrovascular, renal, liver, respiratory, and neurodegenerative diseases. We analyzed 54,105 inpatients, with underlying cause of death distributed as follows: cancer, 24.9%; heart disease, 16.5%; respiratory disease, 12.3%; and cerebrovascular disease, 9.7%. The proportion of intensive care unit (ICU) admission was 9.7%, being the highest in heart disease (20.5%), followed by cerebrovascular diseases (12.6%), and least in dementia/senility (.6%). The proportion of cardiopulmonary resuscitation was 19.6%, being the highest in heart disease (38.1%), followed by renal diseases (19.5%), and least in cancer (6.2%). Multivariate logistic regression analysis revealed that having heart diseases, cerebrovascular diseases, younger age, less comorbidities, and shorter length of stay were associated with an increasing risk of aggressive treatments in the last 14 days of life. The proportion of aggressive treatments at the end-of-life varies depending on the disease; additionally, these treatments were associated with having heart diseases, younger age, less comorbidity, and shorter length of stay. Our findings may help develop and set benchmarks for quality indicators at the end-of-life for patients with non-cancer diseases.
