The purpose of this study was to analyze the effect of long-term care utilization on health care utilization of the elderly. The sample in this study includes 23,269 people older than 65 who are extracted from 2009-2010 long-term care insurance and health insurance claim data. The study group was divided into two groups, namely acute care hospitals and long-term care hospitals. Two part model were used for statistical analysis and instrumental variables analysis were used for controlling endogeneity in the group of long-term care hospitals. This study evaluated the impact of long-term care costs on the probability of health care utilization experience and costs of health care utilization. The results showed that an increase in long-term care costs was associated with an increase in utilization of acute care hospitals, but it was associated with a decrease in utilization of long-term care hospitals. When 1% increase in long-term care costs was associated with 0.5% decrease in costs of long-term care hospitals. On the basis of results, this study concludes that long-term care utilization and utilization of long-term care hospitals for older people are substitutes.
