Association of long-term care needs, approaching death and age with medical and long-term care expenditures in the last year of life: An analysis of insurance claims data.

Abstract

This study aimed to examine whether long-term care needs, approaching death and age were associated with the use of medical and long-term care resources (care/service use and expenditures) in the last year of life among older Japanese individuals. Using data on insurance claims and death certificates, we described the use of medical and long-term care resources in the last year of life by residents of Soma City in Japan aged ≥65 years who died between September 2006 and October 2009. Using a generalized estimating equation, we examined whether long-term care needs, approaching death and age were associated with resource use during each 3-month period in the last year of life. Resource use in medical and long-term care among 882 non-survivors and 8504 survivors were analyzed. Analyses for the non-survivors showed statistically significant associations between: (i) severe long-term care needs and greater service use in outpatient care, higher expenditures for outpatient care and higher expenditures for in-home/facility services; (ii) approaching death and greater use in both inpatient care and facility services; and (iii) being aged 65-74 years and greater service use in outpatient/in-hospital care and in-home/facility services, higher expenditures in outpatient/inpatient care, and lower expenditures for in-home/facility services. The present study showed that severe long-term care needs and approaching death, rather than advancing age, were significantly and independently associated with greater use of resources in both medical and long-term care services.
