The Effect of the Policy of Expanding Coverage for Four Major Diseases: Focused on Out-of-Pocket Payment

가계경제에 큰 부담으로 작용하는 4대 중증질환(암, 심장질환, 뇌혈관질환, 희귀난치질환)의 고액 의료비를 경감시키기 위해, 2013년에서 2016년에 걸쳐 4대 중증질환 보장 강화 정책이 시행되었다. 이 연구는 2013년 4대 중증질환 보장 강화 정책 시행 전･후에 나타난 4대 중증질환의 의료비 변화를 확인함으로써, 2013년에 시행된 4대 중증질환 보장 강화 정책 효과의 평가를 목적으로 한다. 한국의료패널 7차 년도(조사기간 2012년 2~7월)와 9차 년도(조사기간 2014년 3~9월) 자료를 이용하여, 성향점수매칭(propensity score matching)을 결합한 이중차이분석(Difference in Difference)으로 정책효과를 확인하였다. 성향점수매칭 후 다중이중차이분석 결과, ‘비급여’, ‘처방약값’, ‘법정본인부담금’, ‘본인부담금(법정본인부담금+비급여+처방약값)’, ‘건강보험공단부담금’, ‘총진료비(건강보험공단부담금+본인부담금)’는 일부에서 감소하였으나 유의미한 수준의 감소는 아니었음을 확인하였다(p>0.05). 4대 중증질환자의 고액 의료비로 인한 경제적 부담을 덜어주기 위해서는 보다 적극적인 보장성 강화 정책을 추진해야 할 것이다.In South Korea, cancers, cardiac diseases, cerebrovascular diseases and rare intractable diseases cause huge financial burden on households. To help lower their medical cost, the government implemented the policy of expanding insurance coverage for the four major diseases from 2013 to 2016. This study identifies changes in household expenditure on the four major diseases after the implementation of the coverage expansion policy in 2013. By doing so, the study seeks to evaluate the effectiveness of the policy. The study used the 7th⎼year and 9th⎼year data from the Korean Health Panel (KHP) (surveyed from February to July, 2012 and from March to September, 2014, respectively). The effectiveness of the policy was assessed based on the difference in difference method with propensity score matching. As a result of multiple difference in difference after the propensity score matching, it was confirmed that although ‘non-payment items’, ‘prescription drug expense’, ‘statutory payment by patient’, ‘out-of-pocket payment (statutory payment by patient+non-payment items+prescription drug expense)’, ‘national health insurance payment’, and ‘total treatment expense (national health insurance payment + out-of-pocket payment)’ decreased in some parts, this decrease was not at the significant level (p>0.05). In order to ease the large financial burden of medical cost spent on the four major diseases, it will be necessary to pursue a stronger policy to reinforce the coverage of relevant insurances
