Objectives : The purpose of this study is to examine the recognition and needs on the national health insurance coverage of scaling in industry accident injury patients. National health insurance coverage of dental scaling will start in September, 2013. Methods : Subjects were 649 industrial injury patients and they completed self-reported questionnaire. Data were analysed using SPSS version 20.0 for percentage, chi-square test, t-test, ANOVA, post-hoc Scheffe test, and Pearson's correlation coefficient. Results : Recognition on national health insurance coverage of dental scaling was not fully known to industrial injury patients (24.5%). Highly educated and high income workers seemed to recognize national health insurance coverage of dental scaling (p<.001). Recognition for national health insurance coverage of dental scaling revealed a significance (r=.576, p<.001). Most of the industrial injury workers thought that 50,000 to 100,000 Korean Won of dental scaling fee is reasonable. The coverage of dental scaling should be more than twice over 20 years old. Conclusions : It is necessary to encourage the patients to take regular dental scaling checkup and make them know the health insurance coverage of scaling. The preventive oral health care may improve oral health care and quality of life.

Objectives : This study was conducted to estimate the socioeconomic cost of injuries in South Korea. Methods : We matched claims data from national health insurance, automobile insurance and industrial accident compensation insurance(IACI), and mortality data obtained from the national statistical office from 2001 to 2003 by patients unique identifier. Socioeconomic cost included both direct cost and indirect cost: the direct cost was injury-related medical expenditure and the indirect cost included loss of productivity due to healthcare utilization and premature death. Results : The socioeconomic cost of injuries in Korea was approximately 1.9% of the GDP from 2001 to 2003. That is, 12.1 trillion KRW(Korean Won) in 2001, 12.3 trillion KRW in 2002, and 13.7 trillion KRW in 2003. In 2003, direct medical costs were 24.6%(3.4 trillion KRW), the costs for loss of productivity by healthcare utilization were 13.0%(1.8 trillion KRW), and the costs for loss of productivity by premature death were 62.4%(8.6 trillion KRW). Conclusions : In this study, the socioeconomic cost of injuries in Korea between 2001 and 2003 was estimated by using not only health insurance claims data, but also automobile insurance, IACI claims and mortality data. We conclude that social efforts are required to reduce the socioeconomic cost of injuries in Korea, which represented approximately 1.9% of the GDP for the time period specified.

국민건강보험 청구자료는 급여 지급을 위한 자료로 질환에 대한 유병 및 발생자료는 아니므로 보건학적 연구 자료로 활용하기 위해서는 진료에피소드개념을 적용하여 재가공이 필요하다. 따라서 건강보험 청구자료의 보건학적 연구 자료로 활용하기 위한 시범적 진료에피소드 자료를 구축하는 것이 목적이다. 본 연구에서는 무진료기간을 퇴원한 당일 입원한 경우 월 단위 분리청구를 보정하기 위해 0으로 정의하였다. 서울지역에 한하여 호흡기계 질환(ICD10: J00-J99)및 심혈관계 질환(ICD10: I00-I99) 발생의 진료개시일부터 입원 이후 재입원까지 경향을 확인하였다. 무진료기간이 0일 일 때 자료 감소율은 건강보험청구자료의 월 단위 분리청구건으로 인한 것으로 판단된다. 또한 의료기간 종별에 따라 월 단위 분리청구 경향 차이가 있는 것으로 확인 하였다. 본 연구를 통해 구축된 시범적 진료에피소드자료는 기초적 역학정보를 산출하는 자료처리 기법으로 이용될 수 있을 것이다.

본 연구는 자기공명영상(MRI)의 건강보험 적용 전 후 이용량 동향과 이용량에 영향을 미치는 요인을 알아보기 위해 실시하였다. 연구재료는 2004년 1월부터 2013년 12월까지 대전광역시 소재 종합병원(2차 의료기관)의 MRI 실시자료(처방 정보 전달 시스템), 보험심사자료, 건강보험요양급여자료(건강보험심사평가원)를 이용하였고, 분석대상은 2004년(건강보험 적용 전) 3,754명, 2005년 - 2013년(건강보험 적용 후) 4,107명-8,630명 이었다. 분석은 이용자 특성(성별, 연령, 검사부위, 보험유형)과 공급자 특성(진료과, 진료형태)의 MRI 건강보험 적용 전 후 이용량 비교를 $X^2$ 으로 하였고, MRI 이용량에 영향을 미치는 요인분석을 위계적 다중회귀분석으로 실시하였다. 연구결과 건강보험 적용 초기에 한시적으로 이용량이 감소하지만 이후 꾸준히 증가하였다. 특히 여성의 검사 율, Head & Neck의 검사 율, 일반수가적용 환자의 검사 율, 내과의 검사율, 입원환자의 검사 율이 건강보험 적용 전에 비해 증가하였다. 그리고 MRI의 건강보험 적용은 검사 율 증가에 영향을 미치는 것으로 분석되었다(P<.0001). MRI 검사 율이 증가하는 만큼 국민의료비 감소를 위해 건강보험 적용 확대가 적극적으로 이루어져야 할 것이다.

Purpose: The purpose of this retrospective study was to investigate the relationships of types of dental insurance coverage in Korea with sociodemographic characteristics and the prevalence of systemic and oral diseases, as well as to evaluate the socioeconomic impact of Korean dental insurance policies. Methods: Sample cohort data from 2006 to 2015 were obtained from the National Health Insurance Service. Patients were divided into 2 groups. The exposed group comprised patients who received insurance benefits for complete dentures, removable partial dentures, and implant care, while the control group comprised patients who did not receive these benefits. The type of insurance coverage and the prevalence of systemic and oral diseases were compared between the 2 groups. Results: Patients who received benefits in the form of complete dentures, removable partial dentures, and implants had similar sociodemographic characteristics in terms of sex, age, income quintile, and type of insurance coverage to the control group. The prevalence of hypertension, anemia, renal disease, rheumatoid arthritis, osteoporosis, asthma, and cerebral infarction was higher in the exposed group than in the control group (P<0.05). The prevalence of periodontal diseases and dental caries was also higher in the exposed group. Conclusions: Korean dental health insurance policy has been beneficial for the medical expenses of low-income and elderly people suffering from a cost burden due to systemic diseases. However, since there is a tendency to avoid invasive interventions in older patients due to the high risk of systemic diseases, insurance coverage of dentures may be more helpful from a socioeconomic perspective than coverage of dental implant treatments.

Background: Linkage of public healthcare data is useful in stroke research because patients may visit different sectors of the health system before, during, and after stroke. Therefore, we aimed to establish high-quality big data on stroke in Korea by linking acute stroke registry and national health claim databases. Methods: Acute stroke patients (n = 65,311) with claim data suitable for linkage were included in the Clinical Research Center for Stroke (CRCS) registry during 2006-2014. We linked the CRCS registry with national health claim databases in the Health Insurance Review and Assessment Service (HIRA). Linkage was performed using 6 common variables: birth date, gender, provider identification, receiving year and number, and statement serial number in the benefit claim statement. For matched records, linkage accuracy was evaluated using differences between hospital visiting date in the CRCS registry and the commencement date for health insurance care in HIRA. Results: Of 65,311 CRCS cases, 64,634 were matched to HIRA cases (match rate, 99.0%). The proportion of true matches was 94.4% (n = 61,017) in the matched data. Among true matches (mean age 66.4 years; men 58.4%), the median National Institutes of Health Stroke Scale score was 3 (interquartile range 1-7). When comparing baseline characteristics between true matches and false matches, no substantial difference was observed for any variable. Conclusion: We could establish big data on stroke by linking CRCS registry and HIRA records, using claims data without personal identifiers. We plan to conduct national stroke research and improve stroke care using the linked big database.

Objectives : This paper analysed the alternative methods of calculating conversion factor for oriental medicine in the National Health Insurance and estimated the conversion factor(reimbursing price level) of the oriental medical services, based on health insurance claims data and macro economic data. Methods : Comparing cost accounting method, SGR model, and index model to estimate conversion factor in the national health insurance, six empirical models were derived depending on the scope of revenue considered in financial indicators. Classifications of data and sources used in the analysis were identified as officially released by the government. Results and Conclusion : Cost accounting analysis and SGR model showed a two digit decrease in the physician fee schedule of oriental medical services in the national health insurance, while index model indicated a positive increase in the fee reimbursed. As expected, SGR model measured an overall trend of health expenditures rather than an individual financial status of medical institutions, and index model properly estimated the level of payments to oriental medical doctors. Upon a declining share of health expenditures on oriental medicine, a global budget system fixed to a flat rate of total budget could be an opportunity as well as a challenge.
