Age Differences in the Predictors of Medical Service Use between Young-Old and Old-Old: Implications for Medical Service in Aging Society

Abstract

Korea is one of the most rapidly aging countries in the world. Rapidly aging population indicates that the needs for medical service among the elderly will increase as well. As a result of longevity, which increases diversity among the older population, it is important to address age difference within the individuals aged 65 and over. Using the Andersen Model, the current study examines predictors of medical service use among the elderly aged 65 and over and further examines whether there is age difference in the predictors of medical service use between those aged between 65 and 75 and those aged 76 and over. The sample consisted of individuals aged 65 and over who participated in the first wave survey of the KLoSA (Korean Longitudinal Study of Aging). Results showed that (1) the predictors of medical service use in Korea are not exactly the same as those identified in foreign countries, (2) the predictors of inpatient medical service use differ from those of outpatient medical service use, and (3) the predictors of medical service use vary depending on age. Specifically, gender was a significant predictor of inpatient service use only for the old-old, indicating that the male old-old use more inpatient services than the female old-old. Regarding the predictors of outpatient service use, the young-old were different from the old-old in the effects of age, gender, informal social relationships, and chronic illnesses on outpatient service use. Implications of the study were discussed based on the findings.
