What has influenced patient health-care expenditures in Japan?: variables of age, death, length of stay, and medical care.
This study considers variables related to health-care expenditures associated with aging and long-term hospitalization in Japan. We focused on daily per capita inpatient health-care expenditures, and examined the impact of inpatient characteristics such as sex, age, survived or deceased, length of stay, adult disease, and type of medical care received during the duration of each stay. We analyzed data from the Survey of Medical-Care Activities in Public Health Insurance by multinomial logistic regression analyses. Age of patient had little impact on per capita inpatient health-care expenditures per day. As regards length of stay, inpatient stays of 8-14 days had a little impact on health-care expenditures. This study suggested that these results might be due to the kind of medical care received. More research is needed to determine the appropriate medical services to reduce long-term hospitalization. In the last month of care for patients who died, medical examinations had a great influence on health-care expenditures. This study showed that increasing medical examinations in the end-of-life care needs further investigation.
