연구배경: 본 연구는 부당청구 예방형 자율점검제 시범사업의 "개선요청 통보 및 모니터링" 중재활동이 의료기관의 중재 실시 전과 후 청구건수와 청구총진료비 청구행태에 있어서의 변화를 검증하고자 하였다. 방법: 자료는 건강보험심사평가원의 2021년 7월부터 2022년 2월까지 시범사업 항목인 '정맥 내 일시주사(KK020)'를 청구한 기관 중 예방형 자율점검제 대상기관으로 선정된 1,129개 의료기관의 청구자료와 신고 현황자료를 활용하였다. 비교 대상을 선정하기 위해 1:3 비율로 성향점수매칭을 사용하였고, 청구행태 변화를 검증하기 위해 대응표본 t-검정과 t-검정을 실시하였다. 또한 청구행태 변화에 차이가 있는 경우 이에 영향을 미치는 요인분석을 위하여 회귀분석을 시행하였다. 결과: 중재 실시 전과 후의 청구행태는 실험군의 모든 의료기관 종별에서 청구건수와 청구총진료비가 유의하게 감소하였고, 의원의 대조군에서는 유의한 증가를 보였다. 의료기관 및 의사 특성에 따른 중재 실시 전·후 청구행태는 실험군은 의원의 의사 연령 40세 미만을 제외하고 모든 종별에서 유의하게 감소하였다. 대조군은 종합병원과 병원은 개원기간에서, 의원은 표시과목에서 일부 유의한 감소가 있었고, 의사 50세 이상 남성에서 유의하게 증가한 것으로 나타났다. 실험군 대상 의료기관의 청구행태에 변화에 대한 회귀분석 결과, 모든 종별에서 중재 실시 전과 후에 청구건수와 청구총진료비가 유의하게 감소하였다. 또한 의료기관과 의사 특성에서 병원은 개원기간이 길수록 유의한 증가를 나타났고, 의원은 소재지역과 표시과목(기타)에서 유의한 감소를 보였다. 결론: 실험군의 부당청구 예방형 자율점검제의 중재 실시 이후 청구경향의 변화가 연구가설대로 감소하는 경향을 보였다. 이는 제도 시행 직후에 의료기관 스스로 청구행태를 개선하고, 교정하는 사전예방적 활동의 효과가 존재하는 것으로 나타났다. 또한 대조군에서도 통보 대상기관 위주의 제도운영방식에도 불구하고 일부 유의한 감소가 나타난 것은 예방형 자율점검제의 간접적인 효과로 볼 수 있다. 따라서 비대상기관에도 청구행태 개선활동이 이루어질 수 있도록 적극적인 홍보와 교육, 간담회 등의 추가적인 지원과 지속적인 모니터링이 필요하다. 이를 통해 부당청구가 감소될 수 있도록 예방형 자율점검제를 확대하는 것이 바람직하다.

This study was to determine the inappropriate drug use in pediatric outpatients who received 2 or more prescriptions on the same day. Retrospective drug utilization reviews (DURs) were implemented to samples obtained from national health insurance claims data during December 2008 to February 2009, using 5 DUR criteria (duplication, drug-drug interaction, drug-disease interaction, drug-age contraindication, incorrect dosage) established in the Drug Information Framework (DIF)-$Korea^{TM}$, DUR program. Among 38,451 claims analyzed in the study, 74.7% had more than one conflicts in the 5 DUR modules. Among 16,472 patients analyzed, 49.6% had conflicts with duplication criteria composing of ingredient duplication (23.3%) and therapeutic class duplication (39.6%). Incorrect dosages were found in 73.6% of patients and under-dosage conflicts accounted for 59.9%, which was higher than over-dosage conflicts (38.3%). In this study, inappropriate drug prescriptions such as under-dose, pediatric contraindication and therapeutic duplication were prevalent in pediatric outpatient settings, suggesting much more awareness to the society, to prevent drug related problems in a vulnerable pediatric group.

Objectives : The purpose of this study is to analyze the effects of treatment between Western medicine and Korean medicine on Allergic rhinitis patients using national population-based claim data from the Health Insurance Review and Assessment Service. Methods : The subjects of the study were 30,024 patients in the Korean medicine group and 30,024 in the Western medicine group who were diagnosed with Allergic rhinitis from September 1, 2018 to December 31, 2018. Propensity score analysis was used for matching age, sex, etc. at a ratio of 1:1. Cox regression and subgroup analysis were used to estimate the adjusted hazard ratio of recurrence, Asthma, and Atopic dermatitis in Korean medicine group and Western medicine group. In addition, the total treatment period, total treatment cost, and average cost per day of visit were compared and analyzed. Results : Compared to Korean medicine, Western medicine had a significantly higher risk of recurrence at 1.701 times, Asthma occurrence risk at 1.609 times and Atopic dermatitis occurrence risk at 1.098 times. Compared to Western medicine, the total treatment period of Korean medicine was 14.27 days longer, the total treatment cost was 53,591 won more, and the average cost per day was 7,539 won more. Conclusions : This study is a retrospective cohort study using the propensity score matching in Korea to compare the outcomes of Allergic rhinitis between Western medicine and Korean medicine. Further research is needed by considering patients characteristics, and linking with additional data.

Objectives: We aimed to estimate the annual socioeconomic burden of coronary heart disease (CHD) in Korea in 2005, using the National Health Insurance (NHI) claims data. Methods: A prevalence-based, top-down, cost-of-treatment method was used to assess the direct and indirect costs of CHD (International Classification of Diseases, 10th revision codes of I20-I25), angina pectoris (I20), and myocardial infarction (MI, I21-I23) from a societal perspective. Results: Estimated national spending on CHD in 2005 was $2.52 billion. The majority of the spending was attributable to medical costs (53.3%), followed by productivity loss due to morbidity and premature death (33.6%), transportation (8.1%), and informal caregiver costs (4.9%). While medical cost was the predominant cost attribute in treating angina (74.3% of the total cost), premature death was the largest cost attribute for patients with MI (66.9%). Annual per-capita cost of treating MI, excluding premature death cost, was $3183, which is about 2 times higher than the cost for angina ($1556). Conclusions: The total insurance-covered medical cost ($1.13 billion) of CHD accounted for approximately 6.02% of the total annual NHI expenditure. These findings suggest that the current burden of CHD on society is tremendous and that more effective prevention strategies are required in Korea.

Background: Based on the increase in the needs for convalescent rehabilitation medical services in Korea, this study aims to calculate the needs for rehabilitation services and examine its determinants for 229 regions. Methods: Claim data from the Health Insurance Review and Assessment Service were used to estimate patients who need to receive rehabilitation services, and data from various sources were also used for analysis. The number of cases and incidence rates of hospitalization related to convalescent rehabilitation were calculated to estimate the needs for services by region, and the results were visualized via a map. Multivariate regression and fixed effects regression using panel data were performed to identify the determinants of regional variation of the incidence rate. Results: First, the incidence rate of rural areas such as Jeolla-do, Gyeongsang-do, and Chungcheong-do was higher than urban areas (metropolitan cities). Second, the population, proportion of the elder, medical aid recipients, financial independence, traffic deaths, smoking, diabetes rate, and medical infrastructure correlated significantly with the incidence rate. Third, 'rho' values which mean the fraction of variance due to individual terms in panel data regression models were 0.965 and 0.976, respectively. Conclusion: The incidence rate of hospitalizations was correlated with most independent variables in this study and there is a gap between urban and rural areas. These regional disparities are fixed in our society. An improved regional convalescent rehabilitation system is suggested to cover the entire area including rural areas with a high rate of aging.

Objectives: The coronavirus disease 2019 (COVID-19) pandemic has led to a global shortage of medical resources; therefore, we investigated whether COVID-19 impacted the quality of non-COVID-19 hospital care in Korea by comparing hospital standardized mortality rates (HSMRs) before and during the pandemic. Methods: This retrospective cohort study analyzed Korean National Health Insurance discharge claim data obtained from January to June in 2017, 2018, 2019, and 2020. Patients' in-hospital deaths were classified according to the most responsible diagnosis categories. The HSMR is calculated as the ratio of expected deaths to actual deaths. The time trend in the overall HSMR was analyzed by region and hospital type. Results: The final analysis included 2 252 824 patients. In 2020, the HSMR increased nationwide (HSMR, 99.3; 95% confidence interval [CI], 97.7 to 101.0) in comparison to 2019 (HSMR, 97.3; 95% CI, 95.8 to 98.8). In the COVID-19 pandemic zone, the HSMR increased significantly in 2020 (HSMR, 112.7; 95% CI, 107.0 to 118.7) compared to 2019 (HSMR, 101.7; 95% CI, 96.9 to 106.6). The HSMR in all general hospitals increased significantly in 2020 (HSMR, 106.4; 95% CI, 104.3 to 108.5) compared to 2019 (HSMR, 100.3; 95% CI, 98.4 to 102.2). Hospitals participating in the COVID-19 response had a lower HSMR (HSMR, 95.6; 95% CI, 93.9 to 97.4) than hospitals not participating in the COVID-19 response (HSMR, 124.3; 95% CI, 119.3 to 129.4). Conclusions: This study suggests that the COVID-19 pandemic may have negatively impacted the quality of care in hospitals, especially general hospitals with relatively few beds. In light of the COVID-19 pandemic, it is necessary to prevent excessive workloads in hospitals and to properly employ and coordinate the workforce.

경제의 세계화와 지식정보화 사회로의 진입과 함께 초래된 경영환경의 급속한 변화는 의료기관들에게도 경쟁력강화를 위한 변신을 강요하게 되었다. 다시 말하면, 의료기관들은 선진 의료기술의 확보, 환자들에 대한 서비스제고와 함께 경영의 효율성 증대라는 세가지 목표를 동시에 달성해야만 하는 상황에 놓이게 된 것이다. 본 연구는 의료기관들이 당면하고 있는 이러한 세가지 과제 중 병원의 경영효율성 증대를 위한 한가지 대안으로 진료비 청구삭감의 빈도 및 발생 가능성을 낮추기 위한 해법의 마련이 시도되었다. 진료비청구삭감이란 의료기관들이 환자들에 대한 의료서비스에 대한 진료비 중 의료보험으로 인해 환자들이 감면 받은 진료비를 건강보험심사원에 청구하면, 심사원이 의료기관의 청구내역의 적정여부를 심사하여 적정하지 않은 내용에 대한 청구금액을 삭감하는 제도를 이른다. 청구금액에 삭감이 발생하면 해당 의료기관의 수입이 감소하는 것은 물론 원인분석이나 재청구 작업등에 비용과 인력이 이중으로 투입되게 되어 의료기관의 경영에 부담을 주게 되고, 이러한 상황이 빈발하게 되면 해당 의료기관에 대한 환자와 건강보험심사평가원의 신뢰에 문제가 발생하게 된다. 그러므로, 효과적인 진료비 청구삭감분석시스템에 의한 사전대비의 필요성이 높아지게 되는 것이다. 이를 위하여 본 연구에서는 진료비 청구삭감분석을 위한 프로토타입의 개발이 시도되었다. 프로토타입은 데이터마이닝 기법 중 연관분석 알고리즘을 적용하여 개발되었으며, 이렇게 개발된 프로토타입을 D의료원에서 10개월간 발생한 실제 진료데이타를 사용하여 성능을 시험하였다.

Objectives: This study aimed to assess the validity of 'Korean Diagnosis Related Groups-Korean Medicine (KDRG-KM)' which was developed by Health Insurance Review & Assessment Service (HIRA) in 2013 Methods: Among inpatient EDI claim data issued by hospitals and clinics in 2012, the data which included Korean medicine procedures were selected and analyzed. We selected control targets in the Korean medicine hospitals which had longer Episodes-Costliness index (ECI) and Lengthiness index (LI) than average of total Korean medicine hospitals, and compared the results of selection between the major diagnosis-based patient classification system and the KDRG-KM system. Finally, the explanation power (R2) and coefficient of variation (CV) of the KDRG-KM system using practice expenses were calculated. Results: The numbers of control target in Korean medicine hospitals changed from 36 to 32 when patient grouping adjustment method was changed from major diagnosis to KDRG-KM. For expenses of all outpatient claim data on Korean medicine, explanation power of KDRG-KM system was 66.48% after excluding outliers. CVs of expenses of patient groups in Korean medicine hospitals were gathered from under 70% to under 90%, and those in long-term care hospitals mostly belonged under 70%. Conclusions: The validity of KDRG-KM system was assured in terms of explanation power. By adapting KDRG-KM system, fairness of control targets selection for costliness management in Korean medicine hospitals can be enhanced.

Background: With increasing economic evaluation studies on the treatment of or screening tools for liver diseases that cause hepatocellular carcinoma (HCC), interest in the analysis of the medical utilization and costs of HCC treatment is increasing. Therefore, we aimed to estimate the medical utilization and costs of HCC patients, and calculate the cost of main procedures for HCC treatment, including liver transplant (LT), hepatic resection (HR), radiofrequency ablation (RFA), and transarterial chemoembolization (TACE). Methods: We analyzed claim data from January to December 2018 from the Health Insurance and Review and Assessment Service-National Patient Sample (HIRA-NPS-2018) dataset, including data of patients diagnosed with HCC (Korean Standard Classification of Diseases code C22.0) who had at least one inpatient claim for HCC. Results: A total of 715 HCC patients were identified. In 2018, the yearly average medical cost per HCC patient was ₩18,460K (thousand), of which ₩14,870K was attributed to HCC. Among the total medical costs of HCC patients, the inpatient cost accounted for the largest portion of both the total medical and HCC-related costs. The major procedures of HCC treatment occurred most frequently in the order of TACE, RFA, HR, and LT. The average medical cost per treatment episode was the highest for LT (₩87,280K), followed by HR (₩10,026K), TACE (₩4,047K), and RFA (₩2,927K). Conclusion: By identifying the medical costs of HCC patients and the costs of the main procedures of HCC treatment, our results provide basic information that could be utilized for cost estimation in liver disease-related economic evaluation studies.
