The Impact of In-Home Services Utilization on the Institutionalization of Older People in Korea.

As a result of aging populations, institutionalization of older people is creating an increasing financial burden in many countries. The purpose of the present study was to explore the impact of in-home service utilization on institutionalization. The subjects were newly certified as eligible for long-term care insurance between January and February 2009 in Korea. The follow-up period was 40 months, to April 2012. We used logistic regression models to identify factors influencing the transition to institutional service, adjusting for gender, age, living status, income level, activities of daily living, and chronic disease. The institutionalization rate was estimated to be 17.3% over 40 months. The interval from transitional living to institutionalization was 36 ± 8 months. Risk factors of transition to institutional services are being female, having advanced age, living with friends or cousins, getting dementia, and not using in-home services. We determined that institutionalization is mitigated by use of in-home services. Therefore, supplying appropriate in-home services to current nonusers would help to greatly reduce the rate of institutionalization of older people.
