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.

지적재산권은 기술개발의욕 자극을 위해 새로이 물건이나 사상 등의 창작자에게 일종의 배타적 독점권을 부여한 것으로서 1980년대 이후 국제적 관심이 고조되기 시작하였는데, 두 차례의 석유파동 이후 기술이 국제 경쟁력의 주요 결정요인으로 등장하던 시기에 한국을 비롯한 개도국들이 선진국의 기술을 모방하여 첨단기술제품 분야에서 경쟁적 우위를 확보하자 자신들의 경쟁력 확보를 위해 선진국들이 자신들의 통상교섭력을 바탕으로 GATT/UR 등 국제적 협상을 통해 지적재산권 보호문제를 통상문제로 확대시킨 것이다. 이러한 지적재산권에 대한 통상문제와 관련하여 가장 문제가 되는 국가는 역시 미국인데, 미국은 통상법 301조 중 지적재산권 보호에 적용되는 Special 301조를 이용하여 지적재산권 보호에 대한 실효성을 확보하였으며, 당초 제품수입상의 불공정거래행위에 적용하던 관세법 337조를 지적재산권을 침해하는 수입 판매행위에도 적용할 수 있도록 개정함으로써 그 보호수단을 더욱 강화하였는데, 이에 따라 우리도 적절한 대응방안의 모색이 요구되고 있다. 우선 정부의 입장에서는 대내적으로 원천기술 및 개량기술 개발을 통한 기술의 해외의존도 축소, 인센티브 도입 등 직무발명제도 활성화, 해외특허권 취득확대를 위한 중소기업의 해외출원비용 지원, 심사관의 전문화롤 통한 심사의 처리속도 및 질 향상, 특허기술정보 이용체제 개선을 위한 특허청의 정보전산화 및 산업기술정보원 톡허정보센타와의 유기적인 협조체제 구축, 기업의 특허분쟁대응능력 향상을 위한 전담부서 마련 및 국제특허분쟁 전문변리사 양성 등의 대안을 마련할 필요가 있으며, 대외적으로는 PLT협약 등 차후에 있을 국제협약에의 적극적인 참여를 통한 우리나라의 이익도모, 남북 가교역할의 강화 및 한 미 양국간의 법제적 차이에 대한 오해불식, 해당 산업에 영향을 줄 수 있는 로비 활동의 활성화 등의 대안이 필요하다. 또한 기업의 입장에서는 사전적으로 과감한 연구개발투자를 통한 산업재산권 확보, 기술 법률 언어능력을 고루 갖춘 특허전문가의 확보, 국제특허분쟁에 대한 대응체계 구축, 특허권 분쟁발생 방지를 위한 책임소재의 명확화 등의 근본적인 대책과 국제특허분쟁 차단을 위한 철저한 선행기술 조사, 해외기술의 개량 및 이용 촉진을 위한 크로스-라이센스의 활성화, 부실특허권에 대한 적극적인 무효심판청구, 제소정보에 대한 조기 입수, 설계변경이나 특허무효자료조사 등 침해회피 방법의 준비, 위험특허에 대한 철저한 예비조사 등의 부수적인 대책을 마련할 필요가 있으며, 일단 특허분쟁이 발생한 경우에는 당해 분쟁의 자사 생산 제품과의 관련여부 검토, 사건에 필요한 광범위한 정보 수집을 위한 전담팀 구성, 제소인의 특허권에 대한 면밀한 법률적 검토, 제소자에 대한 정확한 정보파악 및 최종 대응방안에 대한 신속한 결정, 자사의 특허를 이용한 제소자에 대한 역제소 등의 대응방안을 강구할 필요가 있는 것이다.

The facial palsy is one of the most common illness in Western-Korean collaborative treatment (hereinafter "collaborative treatment"). The purpose of this study is to analyze facial palsy patients'collaborative treatment use patterns. By analysing the 2014 National Health Insurance Review and Assessment Patient Sample Data (NPS 2014) with the episode of care unit, we have found the following results. First, the collaborative treatment is preferred by patients over 50 years old and female. Second, western medicine mainly focuses on diagnosis and medical examination while korean medicine and collaborative treatment focus more on treatment activity. Third, western medicine showed the shortest treatment period, followed by korean medicine and collaborative treatment. However, the cost of medical treatment per day is highest in western medicine. The analysis of the use patterns of collaborative treatment shown in the study is expected to provide a direction for the development of clinical practice guidelines and the establishment of medical policies in the future.

This study was to address changes on hospital-based home care utilization after long-term care insurance(LTCI) was launched. National electronic data information(EDI) on hospital-based home care from Health Insurance Review Agency in 2007.7~2008.6(prior to LTCI) and in 2009(posterior to LTCI) was analyzed. After the launch of long-term care insurance, 40 hospital-based home health care agencies(HHCA) were diminished and regions not having any HHCA were increased from 53% to 59%. Hospital-based home care utilization was decreased in the elderly(clients 13.4%, visits 20.9%) as well as non-elderly(clients 3.5%, visits 3.9%). It is presumed that diminished HHCAs result in decreased accessibility to hospital-based home health care for non-elderly. The clients, visits, and reimbursed cost per agency were not changed. It is presumed that small agencies were closed already. The total reimbursed cost per agency in 2009 was 121,850,000 won. Results suggest that the government has to give support to open more HHCA to increase the accessibility for non-elderly. Also, hospital-based home care services utilization has to be monitoring regularly.

The purpose of this study was to examine the incidence rates of pressure ulcers depending on the types of healthcare organizations and to determine whether the characteristics of patients and facilities influence on the incidence of pressure ulcers in long term facilities. We analyzed data on 796,857 patients of the 2009 National Patient Sample which was extracted from to claims for medical fees to Health Insurance Review & Assesment Service(HIRA). A total of 3.2% of patients(n=25,339) had at least 1 pressure ulcer during their hospitalization. The pressure ulcer rates were highest in long term care facilities(8.2%, n=11,895) following general hospital(2.7%, n=8,052), hospital(1.7%, n= 5,059). According to logistic regression analysis, urinary incontinence (Odds ratio(OR)=2.462, 95% confidence interval(CI)=2.038-2.974), hypertension(OR=1.456, CI=1.400-1.515), peripheral vessel diseases (OR=1.357, CI=1.200-1.534) were significant predictors of pressure ulcers. As the number of diagnoses, age, and the number of doctors per 100 beds increased, the incidence of pressure ulcers increased. In addition, more number of beds was associated with fewer pressure ulcers.

This study examined health insurance costs of occupational therapy in stroke patients. The subjects were stroke patients, who underwent occupational therapy by hospitalization or out-patient centers in 2010. The cost of occupational therapy was analyzed from the insurance claims data of Health Insurance Review and Assessment Service in 2010. The kinds of occupational therapy were divided according to the insurance fee of occupational therapy in 2010. In-patients who received occupational therapy paid the highest rehabilitation treatment fee, whereas outpatients paid the highest nervous system function test fee. The cost of occupational therapy in the special rehabilitation treatment fee was highest by 25.3 billion won. The number of uses of general hospitals was the highest by 180 thousand but the total cost of long-term care hospital was highest by 10.4 billion won. The number of uses and cost by regional groups was highest in Seoul and Gyeonggi-do province. This study is meaningful in that a cost analysis of occupational therapy in stroke patients was performed for the first time using the stroke data from the whole country. The result can be used to provide basic data to improve the insurance fee in the future.

Purpose : This study aims to estimate the financial cost of rotavirus infection in Korea in the year of 2005. Methods : The incidence rates used were from the epidemiological profile at Jeoungeub District (5.8 cases/1,000 children <5 years old for inpatients, and 22.65 cases/1,000 children <5 years old for outpatients, per year). The health care cost per capita of rotavirus infection (ICD code: A08.0) was extracted from the Health Insurance Review and Assessment Service database in Korea. The patient survey was conducted to capture information about non-medical costs and associated productivity loss incurred by adult caregivers. Results : The number of annual national cases among children <5 years old with rotavirus infection was estimated to be 69,122 (i.e., 55,030 outpatients and 14,092 inpatients). The total cost of rotavirus infection was estimated at 13.3 billion Korean won, comprising 11 billion Korean won (82.7%) of direct medical costs, 1.6 billion Korean won (12.0%) of direct non-medical costs (e.g., transportation and supplies), and 0.68 billion Korean won (5.1%) of productivity lost by adult caregivers. Conclusion : Rotavirus infection carries not only medical costs but also non-medical and indirect costs; together, these costs incur a significant burden on South Korean society. The impact of rotavirus on quality of life and health among patient caregivers was not considered in this study, but it does merit further research.

Background: The purpose of this study was to determine the effectiveness of the specialty hospital system by comparing the medical use of inpatients who had artificial joint replacement surgery in specialty hospitals and non-specialty hospitals. Methods: This study utilized 2021-2022 healthcare benefit claims data provided by the Health Insurance Review and Assessment Service. The dependent variable is inpatient medical use which is measured in terms of charges per case and length of stay. The independent variable was whether the hospital was designated as a specialty hospital, and the control variables were patient-level variables (age, gender, insurer type, surgery type, and Charlson comorbidity index) and medical institution-level variables (establishment type, classification, location, number of orthopedic surgeons, and number of nurses). Results: The results of the multiple regression analysis between charges per case and whether a hospital is designated as a specialty hospital showed a statistically significant negative relationship between charges per case and whether a hospital is designated as a specialty hospital. This suggests a significant low in charges per case when a hospital is designated as a specialty hospital compared to a non-specialty hospital, indicating that there is a difference in medical use outcomes between specialty hospitals and non-specialty hospitals inpatients. Conclusion: The practical implications of this study are as follows. First, the criteria for designating specialty hospitals should be alleviated. In our study, the results show that specialty hospitals have significantly lower per-case costs than non-specialty hospitals. Despite the cost-effectiveness of specialty hospitals, the high barriers to be designated for specialty hospitals have gathered the specialty hospitals in metropolitan and major cities. To address the regional imbalance of specialty hospitals, it is believed that ease the criteria for designating specialty hospitals in non-metropolitan areas, such as introducing "semi-specialty hospitals (tentative name)," will lead to a reduction in health disparities between regions and reduce medical costs. Second, it is necessary to determine the appropriateness of the size of hospitals' medical staff. The study found that the number of orthopedic surgeons and nurses varied in charges per case. Therefore, it is believed that appropriately allocating hospital medical staff can maximize the cost-effectiveness of medical services and ultimately reduce medical costs.

Background: This study aimed to determine the effectiveness of drug utilization review (DUR) evaluation indicators on safe drug use by comparing the changes in DUR inspection rates and drug duplication prescription prevention rates between the pre- and post-implementation of the DUR evaluation indicators of the Healthcare Quality Evaluation Grant Initiative. Methods: This study used DUR data from the Health Insurance Review and Assessment Service in 2018 (pre-implementation) and the evaluation results of the Healthcare Quality Evaluation Grant Initiative in 2023 (post-implementation). The dependent variables were the DUR evaluation indicators, including DUR inspection rate and drug duplicate prescription prevention rate. The independent variable was the implementation of the DUR evaluation indicators, and the control variables included medical institution characteristics such as type, establishment classification, location, DUR billing software company, and number of beds. Results: The results of the analysis of the difference in the prevention rate of drug duplicate prescriptions between the pre- and post-implementation of the DUR evaluation indicators of the Healthcare Quality Evaluation Grant Initiative showed that the prevention rate of drug duplicate prescriptions increased statistically significantly after the implementation of the DUR evaluation indicators. Conclusion: The policy implications of this study are as follows: First, ongoing evaluation of DUR systems is needed. Second, it is necessary to establish a collaborative partnership between healthcare organizations that utilize DUR system information and the organizations that manage it.

This study aims to evaluate the economic value of the heat wave watch/warning (HW/W) forecast provided by the KMA (Korea Meteorological Administration) for the public sector. Local govermenments of Korea currently use the HW/W forecasts as a major input variable to determine the preparative requisite level for reducing potential damage by extreme heat events. To assess the value of the HW/W, which is not a marketable commodity, a decision-making model taking into account the cost and loss was established. The 'cost' variable was defined as the heat wave countermeasures budget for Seoul and Busan in 2016, and the 'loss' variable was set as the amount of health insurance claims for those 65 and older obtained from the Health Insurance Review and Assessment Service. Using this model, the value of the HW/W in 2016 was calculated as KRW 4,133M and KRW1,090M for Seoul and Busan, respectively. In addition, if the KMA reduces the False Alarm of the HW/W by a single instance, the value will be increased by KRW 76.6M and KRW 16.8M for the two cities. The results of this study are useful in quantitatively estimation of the value of the HW/W forthe public sector.
