OBJECTIVE: For improving the drawbacks of previous thoracolumbar spine trauma classification, the Spine Trauma Study Group was developed new classification, Thoracolumbar Injury Classification and Severity Score (TLICS). The simplicity of this scoring system makes it useful clinical application. However, considering criteria of Korean Health Insurance Review and Assessment Service (HIRA), the usefulness of TLICS system is still controversial in the treatment decision of thoracolumbar spine injury. METHODS: Total 100 patients, who admitted to our hospital due to acute traumatic thoracolumbar injury, were enrolled. In 45, surgical treatment was performed and surgical treatment was decided following the criteria of HIRA in all patients. With assessing of TLICS score and Denis's classification, the treatment guidelines of TLICS and Denis's classification were applied to the criteria of Korean HIRA. RESULTS: According to the Denis's three-column spine system, numbers of patients with 2 or 3 column injuries were 94. Only 45 of 94 patients (47.9%) with middle column injury fulfilled the criteria of HIRA. According to TLICS system, operation required fractures (score>4) were 31 and all patients except one fulfilled the criteria of HIRA. Conservative treatment required fractures (score<4) were 52 and borderline fracture (score=4) were 17. CONCLUSION: The TLICS system is very useful system for decision of surgical indication in acute traumatic thoracolumbar injury. However, the decision of treatment in TLICS score 4 should be carefully considered. Furthermore, definite criteria of posterior ligamentous complex (PLC) injury may be necessary because the differentiation of PLC injury between TLICS score 2 and 3 is very difficult.

Korea is regarded as a country that provides a high level of medical services despite a low burden of public health insurance premiums. However, patients face the burden of covering the costs of medical services that are not covered by health insurance, and providers face difficulties because the price of the medical service guaranteed by the health insurance system is very low. In this situation, the government is trying to expand health insurance coverage in the form of the ‘preliminary coverage system’ also known as the ‘selective coverage system’. In this system the government sets the price for a particular health care service not covered by health insurance and then the patient pays for the majority (50% to 90%) of the cost. Although it is possible to manage information about the amount of medical service usage at the national level through this system, it still places a high economic burden on patients with low incomes. In addition, since medical providers are forced to receive uniformly undervalued prices, specialized technologies that have been optimized by medical research institutions are threatened with extinction. Therefore, the preliminary coverage system needs to be reviewed before implementation of expanded coverage within this framework. First, the concept of essential medical care should be established. Based on this concept, the percentage of the cost to be paid by patients should be derived. If the preliminary coverage system is applied to medical services that are not covered by health insurance, a reasonable classification system should be developed and applied along with pricing considering customary market prices.

The health center has to play an important role in promoting community health and satisfying a variety of community health needs and demands in the decentralized Korea. The nearly enacted Community Health Act compels every health center to make its own health plans which intend to deal with local health problems and plan its future health care. This obligation is obviously a big burden to most health centers. They do not have experiences in and abilities of making local health care plans. In order to establish a systematic community health plan, health centers have to concentrate their efforts on enhancing the ability of making health care plan through gathering and analysing the local health informations. However, it is very difficult in reality. This is simply because it will take long time to accomplish these activities. It seems natural that various professionals and researchers participate in carrying out the process of making community health plan in the initial stage. No standardized methodology and analysing framework exist even in the health professional society. Nonetheless, it is common to introduce survey research methodologies in analysing consumer's health care utilization and cost, and in identifying factors influencing health behaviors. Many researchers and professionals have applied social survey methodologies in obtaining information on providers and health policy makers as well. The authors have found that few studies have ever utilized local health data stored at the self-employed medical insurance society as the data source of planning activities. The purpose of this study is to illustrate the usefulness of the data stored at the Sung-Dong Gu Self-employed Medical Insurance Society in establishing the community health plan. The major contents of this study are as follows ; 1. Frequency of utilization by age, area, sex, type of medical care institutions, and some major diseases 2. Medical treatment by type of medical care institutions, by classification of 21 diseases, by frequency of three-character categories 3. Medical treatment of major neoplasm and some chronic diseases by age, sex, and area. The conclusion of this study is that it is of great potentiality to find out the local health problems and to use them in blueprinting the community health plan through comparing the frequency of medical utilization analyzed by a variety of variables with NHI health data or the health data from survey research.

OBJECTIVE: This study was performed to be evaluated the adequacy on DRG classification in Obstetric group and analyzed the difference for medical benefit payment from the insurance and total medical reimbursement according to complication and age in vaginal delivery group and Cesarean section group. METHODS: This study has been analyzed for medical benefit payment from the insurance and total medical reimbursement of patients from University of hospital since Feburary 1999 to December 2000 and the data from Health Insurance Review Agency since Feburary 2001 to July 2001. RESULTS: Since these cases were not reported even 1 case in Korea, there were 113 cases needed to be deleted in DRG classification disease group. In the evaluation of disease severity for DRG classification disease group, there were 11 cases should be added to severe complicating diagnosis, 5 cases should be removed from severe complicating diagnosis, and 6 cases should be added to moderate complicating diagnosis in vaginal delivery and Cesarean section group. Medical benefit payment from the insurance and total medical reimbursement in the group with having severe complication were significantly higher than in the group without complication in Cesarean section group. Medical benefit payment from the insurance and total medical reimbursement in the group with having severe complication in primigravida vaginal delivery group and the group with having severe complication in multigravida vaginal delivery group were significantly higher in the group without complication in primigravida vaginal delivery group and the group without complication in multigravida vaginal delivery group, separately. CONCLUSION: Severity classification system-severe complication, multiple complication, moderate complication, non-complication-should be included in obstetric DRG classification system.

BACKGROUND AND OBJECTIVES: Medical insurance claims (MIC) data are one of the largest sources of outcome data in the form of International Classification of Diseases (ICD) codes. We evaluated the validity of the ICD codes from the Korean National MIC data with respect to the outcomes from acute myocardial infarction (AMI) in the Korean Heart Study. SUBJECTS AND METHODS: Baseline information was obtained from health examinations conducted from 1994 to 2001. Outcome information regarding the incidence of AMI came from hospital admission discharge records from 1994 to 2007. Structured questionnaires were sent to 98 hospitals. In total, 107 cases of AMI with ICD codes of I21- (93 men, 26-73 years of age) were included in the final analyses. ICD code accuracy and reliability (kappa) for AMI were calculated. RESULTS: A large number of AMI cases were from hospitals located in the Seoul area (75.9%). The accuracy of AMI was 71.4%, according to World Health Organization criteria (1997-2000, n=24, kappa=0.46) and 73.1% according to the European Society of Cardiology/American College of Cardiology (ESC/ACC) criteria (2001-2007, n=83, kappa=0.74). An age of 50 years or older was the only factor related to inaccuracy of codes for AMI (odds ratio, 4.6; 95% confidence interval, 1.2-17.7) in patients diagnosed since January 2001 using ESC/ACC criteria (n=83). CONCLUSION: The accuracy for diagnosing AMI using the ICD-10 codes in Korean MIC data was >70%, and reliability was fair to good; however, more attention is required for recoding ICD codes in older patients.

BACKGROUND: Leukocyte reduced (LR) and irradiated (IR) blood components are used to prevent immunological transfusion-related adverse reactions. However, so far, reports on the usage of LR or IR blood components in Korea are scarce. METHODS: Data from January, 2007 to December, 2013 provided by the Health Insurance Review and Assessment Service of Korea were analyzed. Disease categories of the patients were classified according to the Korean Standard Classification of Disease. RESULTS: In 2013, 26.7% of total transfused blood components were leukocyte reduced and an increase of 5.3% compared to 2007. The proportion of IR components increased from 21.4% in 2007 to 27.9% in 2013. The percentage of LR (IR) blood components for RBCs, platelets, and SDPs was 15.4% (14.7%), 35.1% (38.8%), and 75.2% (80.1%), respectively, in 2013. In particular, the percentage of IR FFPs units increased gradually over the years, from 11.2% in 2007 to 22.7% in 2013. LR and IR components were used mainly in hemato-oncology patients but the proportion showed a downward trend. Due to aging of the society, transfusion of LR and IR components has inclined trends in the 70's or more. CONCLUSION: Although the transfusion rate of both LR and IR blood component is increasing, it is still remarkably lower than that in developed countries. Therefore, LR and IR blood components should be used more extensively. For this, reimbursement criteria for National Health Insurance for these blood components should be extended and the fee schedule for LR and IR blood components should be adjusted to reflect clinical practice and patient need.

Thyroid tumors include a heterogeneous group of entities with variable clinical behavior and histology, mostly classified as benign or malignant. Neoplasm of uncertain or unknown behavior in thyroid gland was newly adopted by the 2017 edition of World Health Organization (WHO) classification of endocrine organs. The borderline thyroid tumors include a hyalinizing trabecular tumor and three encapsulated follicular-patterned thyroid tumors (follicular tumor of uncertain malignant potential, well-differentiated tumor of uncertain malignant potential, and non-invasive follicular thyroid neoplasm with papillary-like nuclear features). This review summarizes the changes in the 2017 WHO classification of thyroid tumors, highlights their implications for clinical practice in Korea, and briefly discusses National Health Insurance system, cancer insurance policies, and their associated benefits in Korea.

BACKGROUND: The use of therapeutic materials based on new health technology has increased in recent years in the field of medicine, raising concerns for medical practitioners regarding increased spending on the new therapeutic materials amid the rapid population ageing and increase of chronic diseases in Korea. While therapeutic materials have significant importance in the health care system, they have not been given appropriate attention in the academic world of Korea. The purpose of this study is to identify factors that affect the growth of expenditure on therapeutic materials and to derive implications for an effective management considering the diversity of therapeutic materials. METHODS: Using the claims data of the National Health Insurance Services, specific utilization patterns of groups of therapeutic materials in the middle classification level of Health Insurance Review and Assessment Service from 2007 to 2014 were analyzed. Four categories (J5083: drug eluting coronary stent, D0302: nonmetallic anchor, K6014: gauze, K6023: gauze) that exhibit unique patterns with respect to price and volume were selected. Then, decomposition analysis was performed to identify the largest contributor to the spending growth by dividing the products into existing, new, and abandoned products for the period between 2010 and 2013. RESULTS: The effect of new products had larger impact on spending growth than the effect of core items in drug eluting coronary stent (J5083) and nonmetallic anchor (D0302). In addition, existing products in general included items priced relatively lower when compared with another item manufactured by the same company. In the gauze category, however, existing products had the largest impact on expenditure and the effect of volume was greater than that in other categories. CONCLUSION: This study provides evidence that appropriate management measures classified by the characteristics of therapeutic materials are required for therapeutic materials pricing and reassessment in Korea.

With expanded and extended coverage of the national medical insurance and fast growing health care expenditures, appropriateness of health service utilization and quality of care are concerns of both health care providers and insurers as well as patients. An accurate patient classification system is a basic tool for effective health care policies and efficient health services management. A classification system applicable to Korean medical information-Korean Diagnosis Related Groups (K-DRGs)-was developed based on the U. S. Refined DRGs, and the performance of the developed system was assessed in this study. In the process of the development, first the Korean coding systems for diagnoses and procedures were converted to the systems used in the definition of the U. S. Refined DRGs using the mapping tables formulated by physician panels. Then physician panels reviewed the group definition, and identified medical practice patterns different in two countries. The definition was modified for the difference in K-DRGs. The process resulted in 1,199 groups in the system. Several groups in Refined DRGs could not be differentiated in K-DRGs due to insufficient medical information, and several groups could not be defined due to procedures which were not practiced in Korea. However, the classification structure of Refined DRGs was retained in K-DRGs. The developed system was evaluated for its performance in explaining variations in resource use as measured by charges and length of stay(LOS), for both all and non-extreme discharges. The data base used in this evaluation included 373,322 discharges which was a random sample of discharges reviewed ad payed by the medical insurance during the five-month period from September 1990. The proportion of variance in resource use which was reduced by classifying patients into K-DRGs-r-square-was comparable to the performance of the U. S. Refined DRGs: .39 for charges and .25 for LOS for all discharges, and .53 for charges and .31 for LOS for non-extreme discharges. Another measure analyzed to assess the performance was the coefficient of variation of charges within individual K-DRGs. A total of 966 K-DRGs (87.7%) showed a coefficient below 100%, and the highest coefficient among K-DRGs with more than 30 discharges was 159%.

The aim of this study is to assess the actual epidemiologic features of Kawasaki disease (KD) in Korea using the data from Health Insurance Review & Assessment Service (HIRA) claims from 2007 to 2014. We investigated HIRA claims of patients who had KD (International Classification of Diseases-10, M30.3) as a major diagnosis and were given intravenous immunoglobulin (IVIG) from 2007 to 2014. A total of 39,082 patients were reported during the period. The male-to-female ratio was 1.42 and the median age was 28 months. The incidence rates were 168.3 per 100,000 population aged 0 to 4 years in 2007, 159.1 in 2008, 167.3 in 2009, 190.4 in 2010, 188.2 in 2011, 190.2 in 2012, 210.4 in 2013 and 217.2 in 2014. These rates were much higher than those in the previous studies in Korea. KD occurred more often in early summer (May, June and July) and winter (December and January). The annual incidence rate of KD had been increasing every year, reaching 217.2 per 100,000 population aged 0 to 4 years in 2014. It is the second highest incidence rate of KD in the world after Japan.
