만성질환 노인의 의료비부담 관련요인에 관한 연구

The elderly have higher potential for contracting chronic diseases and suffering from development of a complication. Also, the extended old age period leads the elderly to demand more medical services. All those facts indicate that the elderly need more medical services than any other age groups. Consequently, medical care for the elderly with chronic diseases causes high costs burden. However, there is few studies researching the financial burden of chronic illness of the elderly. This study aimed to 1) understand how much the elderly with chronic diseases pay for medical expenses; 2) find out some specific factors related to health care financial burden; 3) suggest the alternative policies to decrease excessive financial burden of caring for the elderly with chronic illness. National Health and Nutrition Survey, which was surveyed by the Korea Institute for Health and Social Affairs in 1998, was used in this study. 4,707 persons with chronic diseases out of 5385 persons over age 60 were selectively sampled. Using SPSSWIN, correlation analysis, T-test, ANOVA and Regression were used as statistical methods in this study. Stepwise multiple regression was employed to analyze the data with a ratio of health care expenditure to income(financial burden) as a dependent variable. Out of Korean old people, 87% had the chronic diseases and their health care financial burden rate showed the average of 17.9%, which meaned they expended almost 20% income to buy medical services. The variables having a great influence on financial burden were monthly income, activity, limitation and single household of an old person. The excessive financial burden was experienced by people who had more than 4 activity limitations(37.1%) and were in the lowest Income level(32.6%), and single household of an old person(31.4%). The new policies should be considered to 1) reduce the financial burden in these groups and to develop the sliced medical cost system considering the characteristics of chronic illness and income level; and 2) develop the medical management system to care for the elderly with chronic illness.
