일반층과 저소득층의 의료이용에 영향을 미치는 요인 = Factors Related to Health Care Utilization in the Poor and the General Populations

다국어 초록 (Multilingual Abstract)

The purpose of this study is to find the factors that are associated with the probability and the level of the health care utilization in both the poor and the general populations. We analyzed the 2nd round of KOWEPS (Korean Welfare Panel Study) data, using `two-part model` which analyzes the probability of health care utilization experience and the level of health care utilization separately. Both the number of outpatient visit and the length of hospital stay were analyzed. According to the study results, the enabling determinants such as income and health insurance status affected the utilization of medical services in the poor, while the social-structure determinants such as job status and education level affected the general population. The number of outpatient visit predicted individual health practices better than the hospital admission. The length of hospital stay in general population was related to the opportunity cost incurred during hospital stay. In summary, there are significant limitation of the access to health care among the poor, and thus relevant intervention should be implemented to them, because they have different behavior of medical utilization from the general population.
