Accumulated data on medical care utilization among the insured in Korea Medical Insurance Corporation can explain the health status of the population. The purpose of this study was to analyze a change of the disease-mix and utilization pattern by controlling the size of the population enrollment. Major findings of the study are as follows : 1. The changes of inpatient disease-mix a. Utilization rate was 139.2% in 1988 against 1980. b. Disease groups higher than the average utilization rate included neoplasms, endocrine, nutritional and metabolic diseases and immunity disorders, mental disorders etc. Meanwhile, disease groups seen less often were infections and parasistic diseases, diseases of blood and bloodforming, diseases of the digestive system etc. c. Utilization rate was up 106.3% in 1988 compared to 1985, and diseases above that average level were ill-defined intestinal infections, chronic liver disease and cirrhosis, diabetes mellitus, essential hypertension, etc. d. The disease-mix by institution in 1988 compared to 1985 shows that chronic disorders rank high in general hospitals whereas opthalmologic, obstetric, and orthopedic diseases rank high in private clinics. 2. The changes of outpatient disease-mix a. Utilization rate was up 175.2% in 1988 compared to 1980. b. Disease groups higher than the average utilization rate included neoplasms, endocrine, nutritional and metabolic diseases and immunity disorders, mental disorders etc. And disease groups seen less often were infections and parasistic diseases, diseases of the respiratory system, diseases of the genitourinary system. etc. c. Utilization rate was up 104.0% in 1988 compared to 1985, and diseases above that average level were gastric ulcer, diseases of hard tissues of teeth, etc. And diseases seen below that average level were acute nasopharyngitis(common cold). acute upper respiratory infections of multiple or unspecified sites, etc. It was concluded that medical care utilization level was increased, and that, from 1980 to 1988, disease-mix shifted to the chronic disorders. Chronic disorders accounted for more medical care utilization in general hospitals.

Background: Mupirocin, a topical antimicrobial agent has been used for patients with methicillin-resistant Staphylococcus aureus and recently mupirocin resistance was issued in some studies. The objective of this study was to analyze prescription patterns of topical mupirocin, to evaluate appropriateness of prescriptions in the ambulatory setting, and to compare frequency of mupirocin usage in South Korea with that in United States. Methods: Topical mupirocin prescription patterns (the number of prescription and a prescription period), and appropriateness of prescription (including a prescription rate over 10 days, a repeat prescription rate within 30 days and a prescription rate within labeled indications) were analyzed using the 2012 Health Insurance and Review and Assessment service-National Patient Sample dataset of South Korea. The National Ambulatory Medical Care Survey dataset was used to quantify topical mupirocin prescription in United States for comparison. Results: In South Korea, the prescriptions rate for use over 10 days was 3%, the repeat prescription rate within 30 days was 8.87% and the prescription proportion within labeled indications was 33.84%. The most frequent diagnostic code was nonbacterial infection. The prescription rate per 1000 population of topical mupirocin in South Korea was calculated to be 46.07, whereas in United States was calculated to be 13.10. Conclusion: Topical mupirocin has been used frequently and inappropriately, so further studies are required to investigate the rationale behind such prescribing mupirocin patterns.

Using the 1987-2008 quarterly aggregated data of the Household Income and Expenditure Survey, this study investigated the factors influencing household saving rate. The independent variables in the AR regression model were the GDP growth rate, shares of the total household expenditure allocated to tax & social insurance, and education, the variables reflecting the conditions of the asset market including interest rate, stock market index, and real estate price index, and the variables representing the social economic conditions including the index of aging and income inequality. Among the independent variables interest rate, stock market index, and income inequality were found to be significantly associated with the household saving rate. These results suggested that the redistribution and financial market policies favorable to savers may be effective for raising the household saving rate.

The purpose of this study is to investigate the relationship between the work postures and upper extremity cumulative trauma disorders(CTDs) in female medical insurance bill reviewers(n=448). This study included diagnosis for CTDs, anthropometry and job analysis (workstations and posture). The characteristics of subject were 33.6 years of average age and 8.7 years of average work duration. The results were as fallows. Ergonomic conditions of workstation were unsuitable compared with anthropometry result. The height of work surface(79.5 cm) and chair(43.0 cm)were high. work space was small, and legs space under the table was limited. Work postures were awkward compared with recommended neutral postures. Neck flexion($21.0-36.0^{\circ}$), elbow elevation, shoulder abduction ($46.0-47.0^{\circ}$). wrist radial and ulnar deviation, forearm supination and pronation, and wrist repeated motion(12.7-21.5 freq./min) were analyzed as hazardous risk factors by job analysis. The prevalence of CTDs was 32.8 % by medical diagnosis. The prevalence rate of CTDs in hazardous work posture group was significantly greater than safe work posture group both neck-shoulder (relative prevalence = 5.2, p<0.001) and wrist-hand (relative prevalence = 2.5, p<0.05).

Fiscal crisis in the medical insurance system has put the pressure upon hospitals by increasing the rate of curtailment, since the implementation of the separation of prescription and dispensing of medicine. The purpose of this study is to analyse the curtailment of mdical and drug expenditure before and after the system of separation between prescribing and dispensing and to suggest the problems about current inspection system. Data were obtained from 13 general hospitals and used for analysis of trends on medical & drug expenditure, and curtailment in 1999-2000 at three months intervals. The results were as follows; The scale of curtailment for drug expenditure has been increased on outpatient and inpatient since 2000. For the curtailed drug cost with outpatient, the ratio of curtailed drug expenditure has been increased in the case of prescription within the hospital. These results suggest that review system in social insurance were over-focused to control the cost and it might to impede the validity of review function in insurance system. Therefore, it' s needed to develope the scientific and reasonable criteria for Inspection and evaluation of durg expenditure.

Objectives: The purpose of this study was to analyze the factors affecting antibiotic prescription in dental outpatients. Methods: The present study was conducted using data from the National Health Insurance Service - National Sample Cohort. We analyzed prescriptions issued in the dental outpatient department in 2015, for adults over 19 years of age. Antibiotic prescription rates and mean prescription days were analyzed by sex, age, insurance type, presence of diabetes mellitus and hypertension, season in treatment, type of dental institution, and location of dental institution. Multivariate logistic regression was also performed to analyze the factors affecting antibiotic prescription in dental outpatients. Results: A total of 257,038 prescriptions were analyzed. The mean prescription days of antibiotics in dental outpatients were $3.04{\pm}1.08days$, and the prescription rate was 93.0%. Two variables (presence of diabetes mellitus and insurance type) were excluded from the multivariate logistic regression analysis model because they did not significantly affect antibiotic prescription. The possibility of antibiotic prescription was higher in men ${\geq}61years$ of age and those with hypertension. Furthermore, antibiotics were most frequently prescribed in dental clinics rather than dental hospitals, and more frequently in Busan compared to other areas (p<0.001). Conclusions: Several factors were determined to affect antibiotic prescription, and detailed guidelines for consistent antibiotic prescription are needed.

On May 1, 2019, the Minister of Health and Welfare announced publicly the first Comprehensive Plan of National Health Insurance (NHI). The Comprehensive Plan which is the 5-year plan including expenditure and revenue aspect of NHI, is desirable in 42 years of introduction of NHI and 30 years of universal coverage of NHI, though the Plan was late and had some conflict process. The Comprehensive Plan was established without evaluation of Moon's Care Plan, did not included to relationship with NHI and other health security systems, and did not have the blue print of NHI. The Plan was not sufficient in content of adequate health care utilization and relationship with service benefit and cash benefit. The Comprehensive Plan should be modified in considering the blue print of NHI and national healthcare system with participating stakeholder in turbulent environment-low fertility, rapid ageing, low economic growth rate, era of non-communicable diseases, unification of the Korean Peninsula, and 4th industrial revolution. Therefore, I suggest to establish the President's Committee of Improving Healthcare System for the blue print of health care and NHI.

There have been more than 40,000 cases of fires in Korea in the last three years. However, as 'Accidental Fire Liability Act' was judged to be non-conform to the Constitution in 2007, the damages by light mistakes should be compensated. Accordingly, disputes such as compensation claims, litigations and indemnification cases of the victims of fire increased. However, it is so difficult for victims of fire cases to take proper action. So, this study is to help victims of fire cases in the disputes and compensation claims of the victims, and to find actual and practical support system based on the analysis of compensation status. To help victims of fire cases, we need to survey about victims of fire cases with multiple victims. That survey is analyzed to find support plan for victims. Furthermore, to find support plan the current law is needed to be analyzed and reviewed to revision. It is also tried to identify problems in the operation of the Center for victims of Fire currently operated by fire stations and to find countermeasures. In addition, the status of subscription and problem of fire insurance for the compensation for the victims and the method to increase fire insurance subscription rate will be studied.

Purpose: We aimed to analyze the incidence and prevalence of urolithiasis in Korea over the last decade using the National Health Insurance (NHI) sample cohort data. Materials and Methods: From January 2002 to December 2013, we enrolled sample cohort data from the NHI. Patients diagnosed with international classification of diseases code N20 or N13.2 were included. The incidence and prevalence rate was counted from the same period and patients previously diagnosed with urolithiasis were excluded. We compared the incidence and prevalence of urolithiasis by region, age, and sex, and identified the changes. Results: Total 1,111,828 subjects were included. Of these subjects, 36,857 had urolithiasis. The male-to-female ratio was 1.57:1, and total incidence rate was 3.27 per 1,000 person-years (1,000p-yrs). The annual incidence was lowest in 2013 (3,138 patients) and highest in 2005 (3,751 patients). Incidence rate by diagnostic code was highest in ureter stone only (2.49 per 1,000p-yrs) and was lowest in kidney and ureter stone both (0.17 per 1,000p-yrs). Prevalence gradually increased from 3,172 in 2002 and 5,758 in 2013. Jeollanam-do had the highest incidence rate of 3.70 persons per 1,000p-yrs, and Jeju had the lowest rate of 2.84 persons per 1,000p-yrs. In gender analysis, Daegu had the highest incidence (4.56) in males, Jeollanam-do had the highest incidence (3.20) in females. Conclusions: Annual incidence remained stable, whereas prevalence gradually increased. The incidence in male was 1.57 times higher than female, and the peak incidence age was 45-49 years, with the highest incidence occurring in Jeollanam-do and the lowest in Jeju.
