While previous epidemiological studies on temporomandibular disorders (TMD) have been based on a given health center or population sample, no study has been performed on general population of Korea, especially concerning about treatment pattern such as clinician’s specialty involved in TMD treatment, types and amount of prescription medication and cost. This study aimed to investigate magnitude of health visits and treatment patterns for Korean patients with TMD through the computerized database of Health Insurance Review and Assessment Service (HIRAS). Inclusion criteria were all patients registered on the HIRAS database over 3 years' period from 2003 to 2005 and the medical records of patients with TMD as a main diagnosis were extracted. Information collected was as follows; distribution related to gender, age and region and type of hospital the patients visited, treatment duration, clinicians' specialty involved in treatment, cost, types of prescription medication and surgical treatment. The results of this study indicated that 0.15% of the population yearly sought TMD treatment, presenting with increase of incidence over the three years. Most of TMD patients were women (99.8%) and the biggest age group was second and third decades and decreased with age. Seoul and Kyeonggi province presented with higher incidence of TMD compared to the other regions of Korea, which seems to be related with magnitude of population. 56% of TMD patients visited primary care sector and the numbers of treatment visits was the highest in dental clinic (38.4%), followed by orthopedics (28%) and ENT (13.6%) clinics in order. Duration of prescription medication was the longest for anti-inflammatory analgesics, followed by antipsychotic drugs and muscle relaxants. Inpatient care related to TMD was primarily performed in dental hospital compared to medical hospital. Medical database of HIRAS provided comprehensive and vast information on epidemiologic characteristics and treatment patterns for patients seeking TMD treatment, which can be more reliable data to expect medical demand for TMD in condition that accurate diagnosis and standardized treatment is delivered in clinical settings.

Purpose: The purpose of the present study was to investigate needs and satisfaction on the medical services of cancer patients in Jeju Special Self-Governing Province. Methods: Total 174 cancer patients, who visited at the clinic of Jeju National University Hospital, submitted informed consent and participated in this study from July 13 to July 30, 2009. Self questionnaire was used and data were analyzed with Kolmogorov-Smirnov test, Mann-Whitney U test, ANOVA, and Kruskal-Wallis test. Results: Participants expressed the needs of most economical support (3.38 out of 4), followed by counseling of treatment plan (3.22), information of disease (3.07), and disease management except cancer (2.97). Participants were satisfied most with religious counseling (3.41), followed by nursing service support (3.39), employment counseling (3.26), and counseling for family or interpersonal relationships (3.26). The satisfaction of economical support was the lowest (1.98). Satisfaction of men was higher than women, and needs in patients who were living with children was the highest. Patients who were living alone or with children showed the lowest satisfaction about the medical services. There were no significant differences in the general characteristics, however, participants who were older than 60 years of age or had higher income showed lower needs and higher satisfaction. There were no significant differences in the medical characteristics, however, thyroid cancer patients and patients who were treated with radiation therapy or transarterial embolization showed low satisfaction. Conclusion: Cancer patients seemed to need more economical support, information of treatment or disease, and symptom management. Furthermore, there were various needs about the services, depending on family formation or economical support of patients. Therefore, it is certain that patients who were suffering from other cancers, except the 5 major cancers, needed more services. In conclusion, continuous and systemic policy to consider patient's characteristics and needs are needed in community as well as health care system.
The rate of antibiotics prescription for an acute airway infection significantly varies depending upon the diagnosis type, specialty, and the location of the hospital along with many other related factors. The objective of this study is to empirically investigate the possible relationship between the antibiotics prescription rates for an acute airway infection and the degree of competition in the hospital market regions of mainly the providers of primary medical care services such as clinics, internal medicines, pediatrics and otorhinolaryngology department. Using the data from Health Insurance Review and Assessment Service (HIRA) regarding the hospitals' antibiotics prescription rates for the acute airway infection and controlling for selected variables of demand and supply sectors, this study tries to figure out that the degree of competition in the hospital market, regardless of what type of competition indexes we employed, has a statistically significant effect on the variations of antibiotics prescription rate of the clinics in local areas. This result implies that as an economic consideration itself, the change in the degree of competition in the hospital market can play a crucial role influencing the treatment behaviors of the medical doctors. More specifically, this study reveals that as the degree of competition increases the antibiotics prescription rate goes up. This result means that if the market becomes more competitive in a specific region so that it might cause a reduction in doctor's income, doctors with rational decision-making process, recognize that the benefit created from inducing patients' seemingly unnecessary demand for medical care (income effect) would be higher than the costs associated with sustaining their targeted income (substitution effect). It is because that the doctors are more likely to prescribe antibiotics which create relatively higher margins than other medical care services in order to sustain their targeted income when the hospital market competition becomes tighter. Even though this study empirically confirms that antibiotics prescription can be affected by the economic incentives, it still raises following issues as limitations of the study: first issue is about the representativeness of the hospital regions segregated for this study, which might be weak in explaining whether these regions are mutually exclusive in reality. Patients actually consider the quality of services, transportation cost, time costs, and any other related factors choosing the doctors or hospitals, and in that sense, this study rules out 'border-crossing' in using the medical care services. Second issue arises in capturing the data of antibiotics prescription rate. Since we use the average rate for each medical institution, we cannot figure out the average rate for each patient so that we are not able to control for the variation of patients' medical conditions. It is because of the unavailability of data regarding each patient's medical condition from HIRA. Thirdly, since this study mainly analyzes the medical institutions providing primary care such as clinics, internal medicines, pediatrics, and otorhinolaryngology department, it is skeptical of whether those institutions can represent the hospital market in respective regions and truly reflect the degree of competition. It needs to extend the study areas and disease types as well as any micro data for future studies.

Aiming to reveal the employment evolution around interstate highway corridors, an extended shift-share analysis is conducted for metropolitan areas in two interstate highway corridors on the U.S. east coast: I-95 and I-85. Our focus is on knowledge service sectors, specifically finance, insurance, business services and health services for two time periods, 1977-1990 and 1990-2005. In the first period, the two corridors' metropolitan areas have outperformed their regions in terms of both output and labor productivity. But this picture turned negative in later period with some variation by industries. Also variation in performance over time was found even in metropolitan areas in the same corridor or in geographically adjacent areas.
To assess the adequacy of medical manpower and medical fee for the newborn nursery care, the author visited 20 out of 24 hospitals with the pediatric training program in Youngnam area between July 29 and August 14, 1991. Total number of newborn, both normal and sick, admission and discharge in 1-30 June 1991 was obtained from the logbook of nursery. Head nurse and staff pediatrician of the nursery were interviewed to get the current staffing for the nursery and their subjective opinion on the adequacy of nursery manpower and the difficulties in recruiting manpower. Average medical fee charged for the maternity and normal newborn nursery care was obtained from the division of self-audit of medical insurance claim of each hospital. Average minimum requirement of nursing care time for one normal newborn per day was 179.5 (${\pm}58.6$) minutes; 202.3(${\pm}50.7$) minutes for the university hospitals and 164.2(${\pm}60.5$) minutes for the general hospitals. The ratio of minimum requirement of nursing care time and available nursing time was 1.42 on the average. Taking the additional requirement of nursing care for the sick newborns into consideration, the ratio was 2.06. The numbers of R. N. and A. N. in the nurserys of study hospitals were 31%, and 17%, respectively, of the nursing manpower for the nursery recommended by the American Academy of Pediatrics. These findings indicate that the nursing manpower in newborn nursery is in severe shortage. Ninety percent of the head nurses and 85% of the staff pediatrician stated that the newborn nursery is short of R.N. and 75% of them said that the nurse's aide is also short. Major reason for not recruiting R.N. was the financial constraint of hospital. For the recruitment of nurse's aide, short supply was the second most important reason next to the financial constraint. However, limit of quarter in T.O. was the mar reason for the national university hospitals. Average total medical fee for the maternity and newborn nursery cares of a normal vaginal delivery who stayed two nights and three days at hospital was 219,430won. Out of the total medical fee, 20,323won(9.3%) was for the newborn nursery care. In case of C-section delivery who stayed six nights and seven days, total medical fee was 732,578won and out of the total fee 76,937won (12.0%) was for the newborn care. Cost for a newborn care per day by cost accounting was 16,141won for the tertiary care hospitals and 14,576won for the all other hopitals. The ratio of cost and the fee schedule of the medical insurance for a newborn care per day was 5.0 for the tertiary care hospitals and 4.9 for the all other hospitals. Considering the current wage level of the medical personnel, capital investment for the hospital facilities and equipments, and the cost for hospital maintenance, it is hard to expect adequate quality care in the newborn nursery under the current medical insurance fee schedule.
Background: This study aims to examine changes in fraudulent claim counts and total reimbursements before and after enhancements in counterfeit claim controls and monitoring of provider claim patterns under the "Proactive self-audit pilot program of fraudulent claims." Methods: This study used the claims data and hospital information (July 2021-February 2022) of the Health Insurance Review and Assessment Service. The data was collected from 1,129 hospitals assigned to the pilot program, selected from the providers who filed a claim for reimbursement for intravenous injections. Paired and independent t-tests, along with regression analysis, were utilized to analyze changing patterns and factors influencing claim behaviors. Results: This program led to a reduction in the number of fraudulent claims and the total amount of reimbursements across all levels of hospitals in the experimental groups (except for physicians below 40 years old). In the control group, general hospitals and hospitals demonstrated some significant decreases based on the duration since opening, while clinics showed significant reductions in specified subjects. Additionally, a notable increase was observed among male physicians over the age of 50 years. Overall, claims and reimbursements significantly declined after the intervention. Furthermore, a positive correlation was found between hospital opening duration and claim numbers, suggesting longer-established hospitals were more likely to file claims. Conclusion: The results indicate that the pilot program successfully encouraged providers to autonomously minimize fraudulent claims. Therefore, it is advised to extend further support, including promotional activities, training, seminars, and continuous monitoring, to nonparticipating hospitals to facilitate independent improvements in their claim practices.

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.

Objectives: Immunizations have been one of the most effective measures preventing from infectious diseases. It is quite important national infectious disease prevention policy to keep the immunizations rate high and monitor the immunizations rate continuously. To do this, Korean CDC introduced the National Immunization Registry Program(NIRP) which has been implementing since 2000 at the Public Health Centers(PHC). The National Immunization Registry Program will be near completed after sharing, connecting and transfering vaccination data between public and private sector. The aims of this study was to evaluate the immunization module of non-chart system in private clinic with health information system of public health center(made by POSDATA Co., LTD) and immunization registry program(made by BIT Computer Co., LTD). Methods: The analysis and survey were done by specialists in medical, health field, and health information fields from 2001. November to 2002. January. We made the analysis and recommendation about the immunization module of non-chart system in private clinic. Results and Conclusions: To make improvement on immunization module, the system will be revised on various function like receipt and registration, preliminary medical examination, reference and inquiry, registration of vaccine, print-out various sheet, function of transfer vaccination data, issue function of vaccination certification, function of reminder and recall, function of statistical calculation, and management of vaccine stock. There are needs of an accurate assessment of current immunization module on each private non-chart system. And further studies will be necessary to make it an accurate system under changing health policy related national immunization program. We hope that the result of this study may contribute to establish the National Immunization Registry Program.
Unnecessary readmissions could be the result of the inadequate and unnecessary treatments. Adequate quality indicators for readmission are important because they can identify inadequate spending by inpatients as well as quality screening. This study attempted to estimate the cost incurred by unnecessary readmissions. The Health Insurance Claims Data of 18 years or older who were admitted in the tertiary hospitals in 2014 were analyzed. Admissions and readmissions were sorted and readmissions were classified into planned and unplanned readmissions. We adopted 28 days as a criteria for the classification of the readmission. Proportion of the patients were higher in readmissions among cancer, accompanied diseases, and special rehabilitation patients. Cost of the readmissions were 50% of the total cost of the admission among the patients of same diseases, same departments, and same hospitals. Almost 1,000billion Won were used by the unnecessary readmissions. We need to reduce the readmissions in regions, departments, and diseases studying the pattern of the readmissions. National level efforts are required to improve quality of care and reduce cost by the unnecessary readmissions.

As the rapid development of economy in China, the problem in income gaps become a tough and sensitive social problem. Under this social background, this research try to find the main reasons of the income gap among the East China, West China, and the central China, basing on the analysis of its actuality and forming, and then put forward some solution plans. The research shows that in different development levels of China influencing factor of urban-rural income gap is also different. Take East China for example, the education support plays an important part of narrowing income gap. The influence of education support on urban-rural income gaps more significant than industrialization, what is more, its influence has the more reinforce trend, while in the less developed central and western part in China, what can narrowing income gap significantly is industrialization and the support for agriculture. Therefore, in order to solve the problem of income gap between urban and rural areas in China radically, it is not enough to perform medical insurance reform and social insurance reform in the whole county. Besides this, we should perform other kinds of reformation countermeasures which have their regional characteristics. For example, in eastern, the regional governments should reinforce the education system; in central china, they should focus on developing industry; in western, the regional governments should increase the expense to support the agricultural development, and so on. With these countermeasures, they could not only relieve the gap between urban and rural areas in China, but also ensure to develop economy substantially and stably in the whole country.
