다국어 초록 (Multilingual Abstract)

Background: Bankrupted households have recently been increased due to excessive medical expenditure in Korea. They have not been protected from economic risk when household`s member has severe diseases that need a lot of money for treatment. Purpose of this study examines policy effect by comparing unmet needs` change of policy object households and non-object groups. Methods: We used Korea Health panel 2nd. 4th data collected by Korea Institute for Health and Social Affairs and National Health Insurance Service. Analysis subjects were 381 households (pre-policy) and 393 households (post-policy) that had cancer and cardio-vascular and cerebrovascular diseases. Since it was major concern that estimates benefit strengthening policy started by certain time, we setup comparing households which had diabetes, hypertension disease. Comparison subjects were 393,247 households, respectively and we evaluated policy effect using difference in difference (DID) model. Results: Although unmet needs of policy object households were higher than non-object groups, policy execution variable af-fected negative direction. But interaction-term which shows pure effect of policy was not statistically significant. We utilized multi-DID model to examine factors affecting unmet needs causes. Copayment assistance policy did not significantly affect households that responded to ``economic reason,`` and ``no have time to visit`` for unmet needs causes. Conclusion: The second copayment assistance policy did not significantly give positive effect to beneficiary households than non-beneficiary groups. When we consider that primary purpose of public insurance guarantee high medical expenditure occurred by unexpected events, it needs to deliberate on switch of benefit strengthening policy that can assist vulnerable people. Also, we sug-gest that government forward a policy covering non-reimbursable medical expenses as well as switch of benefit strengthening di-rection because benefit policy do not affect non-covered medical cost which accounts for quarter of total health expenditure.
