After the introduction of National Medical Insurance in 1989, the medical demand has rapidly increased. The impact of increased medical demand was followed by an increase in the number of claims in need of review. We studied a new, fair method for reducing the number of claims reviewed. We analysed 90,583 outpatient claims submitted between September and October; claims were made for services given August of 1994. We finally suggested a screening system for claims review using a statistical method of discriminant analysis of the medical costs. The results were as follows. 1. In the cut-off group, age, days of medication, number of hospital or clinic visits, and total charge were significantly high. The cut-off rates according to the hospital-type and existence of accompanied disease were significantly different 2. According to ICD, the cut-off rate was highest in peripheral enthesopathies and allied syndromes(20.76%), lowest in acute sinusitis(0.93%). The mean charges were significantly different according to ICD and existence of cut-off. 3. We build discriminant functions by ICD with such discriminant variables as patient age, sex, existence of accompanied disease, number of hospital or clinic visits, and 9 detailed hospital or clinic charges included in claim. 4. We applied the discriminant function for screening those claims that were expected to be cut-off. The sensitivities comprised from 40% to 70%, and specificities from 70% to 95% by ICD. Acute rhinitis had highest sensitivity(100.00%) and other local infections of skin and subcutaneous tissue had highest specificity(98.45%). The expected number of cut-off was 17,762(19.61%). The total sensitivity was 49.62%, the total specificity was 82.57% and the error rate was 19.66%. We lacked economic analysis such as cost-benefit analysis. But, if the new method of screening claims using discriminant analysis were applied, the number of claims in need of review will reduce considerably.
This study aims to examine the effect of socioeconomic status (hereafter, SES) on healthcare utilization of the patients with rare and incurable diseases. Information of 2,973 patients who were self-employed insured and utilized healthcare service in 2007 was drawn from the National Health Insurance (hereafter, NHI) claim data. SES was set as four groups based on the monthly contribution. Outcome variable was the expense for outpatient and in-hospital services, which was log-transformed and square-rooted in oder to obtain normal distribution. Covariates included age, gender, residence and diagnosis. To examine the effects after controlling for covariates, we employed generalized estimating equation model, since patients with the same diagnosis are likely to have similar characteristics of demographics and healthcare utilization. Univariate statistics showed that lower SES was associated with less utilization of healthcare services. After controlling for covariates, a significantly smaller amount of money was expended for the lowest SES group compared to the highest one. Rural residence was associated with less utilization, except that residents in Seoul significantly more utilized outpatient services in tertiary hospitals. Considering that there is a subsidy program for the low income patients, such differences in healthcare utilization according to SES seems to result from the burden of out-of-pocket payments for uncovered services of the NHI.
Objective Several cell line studies have demonstrated thioridazine's anticancer, multidrug resistance-reversing and apoptosis-inducing properties in various tumors. We conducted this nationwide population-based study to investigate the association between thioridazine use and cancer risk among adult patients with schizophrenia. Methods Based on the Psychiatric Inpatient Medical Claim of the National Health Insurance Research Database of Taiwan, a total of 185,689 insured psychiatric patients during 2000 to 2005 were identified. After excluding patients with prior history of schizophrenia, only 42,273 newly diagnosed patients were included. Among them, 1,631 patients ever receiving thioridazine for more than 30 days within 6 months were selected and paired with 6,256 randomly selected non-thioridazine controls. These patients were traced till 2012/12/31 to see if they have any malignancy. Results The incidence rates of hypertension and cerebrovascular disease were higher among cases than among matched controls. The incidence of hyperlipidemia, coronary artery disease and chronic pulmonary disease did not differ between the two groups. By using Cox proportional hazard model for cancer incidence, the crude hazard ratio was significantly higher in age, hypertension, hyperlipidemia, cerebrovascular disease, coronary artery disease and chronic pulmornary disease. However, after adjusting for other covariates, only age and hypertension remained significant. Thioridazine use in adult patients with schizophrenia had no significant association with cancer. Conclusion Despite our finding that thioridazine use had no prevention in cancer in adult patients with schizophrenia. Based on the biological activity, thioridazine is a potential anticancer drug and further investigation in human with cancer is warranted.

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: In workers with moderate to severe work-related traumatic brain injury (wrTBI), this study aimed to investigate the effect of the timing of rehabilitation therapy initiation on the length of hospital stay and the factors that can influence this timing. Methods: We used data obtained from the Republic of Korea's nationwide Workers' Compensation Insurance. In the Republic of Korea, between the years 2010 and 2019, a total of 26,324 workers filed a claim for compensation for moderate to severe wrTBI. Multiple regression modeling was performed to compare the length of hospital stay according to the timing of rehabilitation therapy initiation following wrTBI. According to the timing of the initiation of rehabilitation therapy following TBI, the proportions of healthcare institutions that provided medical care during each admission step were compared. Results: The length of hospital stay for workers who started rehabilitation therapy within 90 days was significantly shorter than that for workers who started rehabilitationment were first admitted to tertiary hospitals. Approximately 39% of patients who received delayed rehabilitation treatment were first admitted to general hospitals, and 28.5% were first admitted to primary hospitals. Conclusions: Our findings demonstrate the importance of early rehabilitation initiation and that the type of healthcare institution that the patient is first admitted to after wrTBI may influence the timing of rehabilitation initiation. The results of this study also emphasize the need to establish a Worker's Compensation Insuranceespecialized rehabilitation healthcare delivery system.
In this study, a practical model for health information management education using the EMR education system at universities for nurturing health care information managers was studied. Currently, there is no practical training course for health care information management in the standards for evaluation and certification of health care information management education introduced to strengthen the job competency of health care information managers. Accordingly, the program was constructed so that the practice program suggested as an educational environment in the Health and Medical Information Management Education Evaluation and Certification Manual can be practiced in the EMR education system. In addition, a practical model that can be performed according to the on-site practice guidelines for health and medical information management for each program was studied. Using the health care information management education EMR system, master data management, patient registration, doctor prescription, medical cost calculation, health insurance claim management, form management, discharge registration, cancer registration, unrecorded management, health care data management, health care statistics, A practice model was studied so that practice on information protection/security management can be performed. It will be possible to play a role as a health care information management expert by raising the quality level of health care information management education through systematic and standardized health care information management practice courses at universities. Accordingly, it is necessary to cultivate health care information management experts who develop and manage medical services based on medical data analysis through practical training of health care information managers.
Objectives : To investigate the utilization patterns of non-steroidal anti-inflammatory drugs (NSAIDs) among the elderly with osteoarthritis (OA) undergoing primary ambulatory care in Busan metropolitan city, Korea. Methods : OA patients, aged 65 years and over, were identified from the Korean National Health Insurance Review Agency drug prescription database. The subjects had at least one episode of claim for OA (ICD-10-CM: M15-M19) between August 1, 2000 and February 28, 2002. Trends in the determinations of NSAIDs utilization were identified using chi-squared tests for trend. Results : There were 47,711 osteoarthritic patients. The total number of visits by these patients was 177,443, with a total frequency for NSAID prescriptions of 214,952. Seventy-nine percent of the OA patients were female. NSAIDs were prescribed on 133,284 visits (75.1%) and the proportion of prescriptions was significantly increased with age. Only the proportion of visit when NSAIDs were prescribed decreased, from 65.1 to 43.5%, during the study period (p<0.001). However, the proportion of combined treatments with anti-ulcer drugs was increased. The use of NSAIDs injections was decreased. Of the individual NSAIDs, diclofenac (28.7% of total frequency of NSAID prescriptions), piroxicam (15.0%) and talniflumate (8.7%), were the most frequently prescribed. Among the NSAIDs prescribed OA visits, 45.7% used two or more NSAIDs. Conclusion : The total proportion of NSAIDs prescribed to the osteoarthritic patients was higher than in other studies. The decline in the use of NSAIDs during the study period, and the frequent selection of safer medications, such as combination therapy with anti-ulcer drug, may reflect the risk awareness of the use of NSAIDs.
This study presents the variations on drug utilization for outpatients' URI, gastritis. and hypertension by the type of hospital- tertiary hospital. general hospital. hospital. clinic. It investigated drug expenses. daily drug expenses. days of medication. the highest price of the drugs used. and the number of the different drugs used for each disease and type of hospital. This study also performed analysis to see how much the variations of variables related to drug use affect the variations of drug expenses. The dependent variable was drug expenses and the independent variables were days of medication. the average price of the drugs used. and the number of the different drugs used. Analysis of the drug utilization was performed on NFMI(National Federation of Medical Insurance) 1994 medical expense claim data. Patients with secondary diseases were excluded. In this study. 379 patients with URI, 386 patients with gastritis. 1.257 patients with hypertension were included. It was founded that there were large variation on drug utilization between the types of hospital for same diseases. Days of medication were longest in tertiary hospitals and shortest in hospitals or clinics. Clinics showed the lowest daily drug expenses in all of the diseases investigated. Daily drug expenses were highest in general hospitals or hospitals. which also tended to use drugs of higher price than other types of hospital. General hospitals and hospitals had larger variations in daily drug expenses and the highest price of drugs. It suggested that drug might be utilized overly in general hospitals and hospitals and some other factors might influence on drug utilization in these hospitals. It was found that the variations of drug expenses were affected by the variations of drug price and days of medication rather than the number of the different drugs. Then the strategy to reduce the variations of drug utilization and to improve the quality of drug utilization should focus on the drug price and days of medication. Further study is needed to assess the quality as well as the variation of drug utilization and to show the factors which affect them.
This study presents the status on drug prescription for clinic outpatients' bronchitis, gastritis, and gastric ulcer, and also the physician factors that affects their prescriptions. In this research project the physician factors are as follows: their demographic features, their work related features, education related features, drug information related features and drug promotion related features. The variables in drug prescriptions are drug expenses, daily drug expenses, days of medication, the highest price of the drugs used and the number of the different drugs used. Analysis of the use of prescription drugs was performed on NFMI(National Federation of Medical Insurance) 1994 medical expense claim data. Data on physicians' characteristics were collected by mailing surveys. Patients with secondary diseases were excluded. In this study, 388 adults with bronchitis, 1,038 children with bronchitis, 1,158 patients with gastritis, 369 patients with gastric ulcer were included. The older physicians tend to allow the lower drug costs: this explains that the older doctors who are more experienced less depend on the medicines. It can be also explained that doctors are likely to use the medicines that had been used for their intern and resident practice/training period. General practitioners give more intensive prescription compared to specialists. And specialists prescribed medicines to patients for longer period. The doctors' prescriptions for patients are largely affected by commercial sources. So objective and reliable sources for drug information is needed for patients' benefits. Physician factors explain better at the daily drug expenses, the drug price and the number of different drugs than days of medication. Gastric ulcer are better explained by the prescription model adopted in this study than other diseases.
The objective of the current study is to provide basic data necessary for the development of systematic program that is required for the systematic occupational work training of dental hygienists who newly employed at dental hospitals or clinics. The results of the surveys were listed as in below. The survey was conducted for 175 experienced dental hygienists who are in charge of occupational work training in 6 regions(Seoul, Kyunggi, Busan, Ulsan, Kwangju, Chungnam, Kyungnam) of the country where the occupational work training for new dental hygienists is systematically operated. 1. The recognition of experienced dental hygienists for the importance of occupational work training revealed that image training was the most importantly recognized by dental hygienists in Seoul Kyunggi regions(pE.01). In case of Busan region, periodontic training and conservative dentistry training were the most importantly recognized, and customer service training was mostly highly recognized in Ulsan region(pE.01). In case of Kwangjuregion, dental health insurance claim training was recognized as most important subject, and Patient consultation training was the most importantly recognized in Chungnam region. In case of Kyungnam region. Oral surgery was recognized as the most important training subject. 2. Regard on the importance of the range of occupational work training, the experienced dental hygienists with less than 2 years of experience were found to recognize the training of greeting and naming most importantly, the dental hygienists with 2~3 years of experience most importantly recognized oral surgery, and the dental hygienists with 4~5 year of experience were found to recognize conservative training most importantly. In case of dental hygienists having 6~9 year of experience recognized periodontic and conservation trainings as the most important subjects, and the dental hygienist having more than 10 years of experience were found to recognize conservative and image trainings mostly importantly.
