Objectives: The purpose of this study was to analyze the medical cost of facial paralysis in payer perspective and to estimate the practice pattern of patient using 2011 Health Insurance Review & Assessment Service-National Patients Sample(HIRA-NPS). Methods: Basic statistical system was used for descriptive analysis of NPS dataset. A table for general information (table20) was extracted by disease code, and social demographic characteristics, distribution of the use among inpatients and outpatients, utilization of each kind of medical care institutions, medical cost were analyzed. Subgroup analysis was conducted for assuming the practice pattern of korean medicine and western medicine. Results: A total of 8,219 people and 64,345 claims data were identified as having facial paralysis. Proportion of outpatient was 95.23%, inpatient 0.84% and patient using both services 3.93%. Mean patient charges was 44,229 won per outpatient, 178,886 won per inpatient and 523,542 won per patient using both services. Utilization of korean medical care institutions was 68.81%(claims), 40.46%(patients), utilization of western medical care institutions was 31.19%(claims), 59.54%(patients). The amount charged by korean medical care institutions was 52.61% and western medical care institutions was 47.39%. Cost per claim was higher than those of the korean treatment and cost per patient of western treatment was lower than those of the korean treatment. Conclusions: The research assessed the medical cost and practice pattern associated with facial paralysis. These findings could be used in health care policy and subsequent studies.

Objectives : The purpose of this study is to analyze the proportion of admission via the emergency room(the rest is ER) in an emergency medical center and to examine the factors related to admission. Methods : This study used 2005 National Health Insurance claims data for admitted patients of 112 hospitals having emergency medical centers in Korea. The study sample had 2,335,610 patients. The data was classified into emergency admission and non-emergency admission. To investigate the factors affecting the type of admission, the following were included as independent variables: type of health assurance_(national health insurance beneficiaries or medical aid beneficiaries), demographic characteristics_ (sex, age), cause of admission_ (disease or injury), whether an operation was performed or not, DRG severity level, the number of beds, and the location of the hospital. Data were analyzed using the Chi-square test for the differences in emergency admission rates for each variables, and multiple logistic regression analysis was used for identifying the factors affecting admission type. Results : The proportion of admission via the ER accounted for 40.6% of the total admission among hospitals having emergency medical centers. The risk of admission via ER was relatively high for patients who were male, the aged, the injured, the surgical patients, the patients having more severe symptoms, and the patients admitted the hospitals located in metropolitan areas, and the patients admitted the hospitals having 300-699 beds. Medical aid patients were more likely admitted through the emergency room than health insurance patients after other variables ware adjusted. Conclusions and Discussion : We analyzed the proportion of admission via the ER for the total admission rate of hospitals having an emergency medical center in Korea. And we explored the factors related to admission via the ER. This proportion may be used as an indicator of the adequacy of medical utilization or low accessibility to hospitals of patients with low socioeconomic status.

Purpose: Health expenditure and utilization of Korean medicine are increasing every year. Since Chuna Manual Therapy was covered by National Health Insurance in 2019, it is predicted that the usage of Chuna Manual Therapy would be also increasing. However, there are few studies about Chuna Manual Therapy using Korean National Health Insurance claims database. Therefore, we will investigate the utilization trend of outpatient's Chuna Manual Therapy using Korean National Health Insurance database and suggest political implications. Methodology: The Korean National Health Insurance claims database was used to identify outpatient's Chuna Manual Therapy usage spanning 4 years from 2019-2023 and the number of Chuna Manual Therapy claims were approximately 18.61 million. Findings: The number of Chuna Manual Therapy claims and patients, health expenditure of Chuna Manual Therapy have been increasing spanning 4 years among over 65 aged. In the case of female patients, the number of Chuna Manual Therapy claims was more than male patients and health spending related to Chuna Manual Therapy was also higher than male patients. Most patients visited Korean medicine clinics due to musculoskeletal diseases, and most claims were from rural regions. Practical Implication: Since Chuna Manual Therapy was covered by National Health Insurance in 2019, Utilization of Chuna Manual Therapy has been increased overall. In particular, Chuna Manual Therapy is mostly implemented in the elderly, Korean medicine clinics, and local areas, thus policy managers will need to consider this.

Objectives: The optimal duration of maintenance treatment for patients with first-episode schizophrenia (FES) remains unclear. We examined the first antipsychotic treatment duration and its association with re-initiation of treatment using a nationwide claim database. Methods: Data from the Health Insurance Review and Assessment Service database in South Korea for 2007-2016 were used. Linear regression analysis and Cox proportional hazard models were used to evaluate the associations between the duration of the first antipsychotic treatment, time to re-initiation of treatment, and occurrence of treatment re-initiation. Results: Of 30,143 patients with FES, 80.4% (n=24,231) received <2 years of the first antipsychotic treatment. In patients who discontinued treatment (n=23,030), the rate of treatment re-initiation was 74.2% (n=17,086). As the duration of the first antipsychotic treatment increased, the time to re-initiation of treatment decreased (β=-0.146, p<0.001); however, the rate of treatment reinitiation was relatively constant (hazard ratio=1.001, p<0.001). Conclusion: Long-term antipsychotic treatment was not significantly associated with the rate of treatment re-initiation but showed a negative association with the time to re-initiation of treatment. Further research is needed to better understand the optimal treatment duration for FES.

The purpose of this study was to analyze the claim data of Health Insurance Review & Assessment Service to determine what factors affected the length of stay in patients aged 65 and older and undergoing total knee arthroplasty due to the principal diagnosis of gonarthrosis by the type of medical institutions. As a result of making an analysis, gender, age, medical security type, severity, residential area and the number of sickbeds were identified as the factors that influenced the length of stay in each type of medical institutions. At this point in time when an increase in the elderly population triggered by population aging and another subsequent increase in medical expenses put a heavy strain on household and national economy, it's necessary to consider how to shorten the length of stay and how to ensure the efficient management of sickbeds based on the findings of this study. In addition, this study is of significance in that it could be used as basic data on quality life-care for elderly patients by the introduction of a systematic management system geared toward lessening patient burden for medical expenses.

Background: Issues concerning with the classification accuracy of Korean Outpatient Groups (KOPGs) have been raised by providers and researchers. The KOPG is an outpatient classification system used to measure casemix of outpatient visits and to adjust provider risk in charges by the Health Insurance Review & Assessment Service in managing insurance payments. The objective of this study were to refine KOPGs to improve the classification accuracy and to evaluate the refinement. Methods: We refined the rules used to classify visits with multiple procedures, newly defined chemotherapy drug groups, and modified the medical visit indicators through reviews of other classification systems, data analyses, and consultations with experts. We assessed the improvement by measuring % of variation in case charges reduced by KOPGs and the refined system, Enhanced KOPGs (EKOPGs). We used claims data submitted by providers to the HIRA during the year 2012 in both refinement and evaluation. Results: EKOPGs explicitly allowed additional payments for multiple procedures with exceptions of packaging of routine ancillary services and consolidation of related significant procedures, and discounts ranging from 30% to 70% were defined in additional payments. Thirteen chemotherapy drug KOPGs were added and medical visit indicators were streamlined to include codes for consultation fees for outpatient visits. The % of variance reduction achieved by EKOPGs was 48% for all patients whereas the figure was 40% for KOPGs, and the improvement was larger in data from tertiary and general hospitals than in data from clinics. Conclusion: A significant improvement in the performance of the KOPG was achieved by refining payments for visits with multiple procedures, defining groups for visits with chemotherapy, and revising medical visit indicators.

Under the new system of 'Separation of pharmaceutical prescription and dispensing' in Korea, which was implemented in 2000, physician could not dispense a medicine, and outpatient should have a physician's prescription filled at a drugstore. After pharmacist makes up outpatient's prescription, National Health Insurance Service(NHIS) pay for outpatient's medicine to pharmacist, except an outpatient's own medicine charge. And NHIS only pay for outpatient's prescription fee to physician and, physician doesn't derive profit from dispensing medicine in itself. Nevertheless, if physician writes out a prescription with violation of 'Criteria for the Medical Care Benefits', NHIS clawed back the payment of outpatient's prescription and medicine from the physician or the medical institution which the physician belongs to. In the past, NHIS's confiscation was in accordance with 'the National Health Care Insurance Act, Article 52, Clause 1'. But, since 2006 when the Supreme Court declared that there was no legal basis on the NHIS's confiscation of outpatient's medicine payment, NHIS had put in a claim for illegal prescriptions on the basis 'the Korean Civil law, Article 750(tort)'. So, Many medical institutions filed civil actions against NHIS. The key point of this actions was whether the issuing outpatient prescriptions with violations of Criteria for the Medical Care Benefits constitute of the law of tort. On this point, the first trial and the second trial took different position. Finally the Supreme Court acknowledged the constitution of the law of tort in 2013. In this paper, the author will review critically the decision of the Supreme Court, and consider the relativeness between the legal effect of Criteria for the Medical Care Benefits and the constitution of the issuing outpatient prescriptions with violations of Criteria for the Medical Care Benefits as the law of tort.

Objectives : Among young generation, the prevalence of spinal disorders is known to be increasing. This study aimed to analyze the clinical data of spinal disorder in young ages in Korea. Methods : Number of patient, kinds of disorder, and medical cost were analyzed for patients(7~18 years) underwent spinal disorders using computerized database of Health Insurance Review and Assessment Service(HIRAS) from 2004 to 2008. We included dorsopathies as spinal disorder according to Korean Classification of Diseases(KCD) and excluded spinal disorder caused by trauma. We compared the data of traditional Korean medicine treatment with that of western medical care. Results : 4.8% of the children and adolescents had medical treatment with spinal disorder in 2008. The claim number and medical cost for both traditional Korean medicine and western medicine treatment are increasing 1.8 and 1.3 times respectively over 5 years. Total medical spent of western clinic was 2.1 times than those of traditional Korean clinic. The most common spinal disorder was dorsalgia(31.8%) and scoliosis(13.5%) in western clinics while back pain(29.0%) and neck pain(10.8%) in oriental clinic. Conclusions : We first reported the clinical tendency of spinal disorder in Korean children adolescents from 2004 to 2008. This study will support the development of a strategy for traditional Korean medicine-based prevention or treatment of spinal disorders in young generation.
