Purpose: We examined the relationship between operating income and volume of medical services provided at general hospitals in 2018 according to characteristics of general hospitals and measured as operating income(net income) and volume(adjusted inpatient days) covered or non-covered by National Health Insurance(NHI). Methodology: Finance data from income statement reports in 212 general hospitals and the national health insurance claim data of these hospitals were used. The characteristics of the general hospital were divided into structural, operational, financial, and patient aspects. Operating income and volume were divided into covered and non-covered by NHI. Findings: The results showed high volume hospitals tended to be more profitable than low volume hospitals, especially in non-covered services. Operating income was more likely to be sensitive to non-covered services volume than to covered services volume. Practical Implications: It is necessary to understand the volume of services in non-covered, in order to obtain reliable cost information to be used for the fee schedule. Researches on small size hospitals(<160 beds) are needed, with a large variation in the volume of services and a strong tendency to compensate for the loss in the covered part in non-covered part.

Purposes: The purpose of this study was to analyze the factors associated with current smoking status in Wonju-si and Chuncheon-si, and to study the cause of difference in smoking rates between these two regions. Methodology: Data was from the National Health Insurance Service database from 2019 to 2020. Current smoking status was based on the response to the health examination questionnaire. Logistic regression analysis was conducted to identify factors associated with current smoking status. The study included 207,307 individuals from Wonju-si and 173,698 individuals from Chuncheon-si. Findings: The smoking rate of Wonju-si was 19.83%, and Chuncheon-si was 18.20%, showing a difference in the smoking rates between the two regions. Logistic regression analysis found that men, those aged 40-49, being a self-employed insured, a medical-aid beneficiary, having a lower income, working in construction, transport, storage, communication, or manufacturing industries, having a high-risk drinking level and being underweight were significantly associated with a higher likelihood of smoking(p<0.05). Additionally, having a chronic disease was associated with a lower likelihood of smoking in the case of Chuncheon-si(p<0.05). Practical Implication: This study found the differences of factors associated with smoking rates between the two regions and could provide implications for establishing intervention programs or policies that could contribute to lowering the smoking rate in areas with high smoking rates.

Objectives: In this preliminary study, we investigated the clinical characteristics of patients who were first diagnosed with psychotic disorder and explored the impact of the adherence to antipsychotics on long-term medical use. Methods: All national health insurance claims related to psychotic disorders including gender, age, income, and drug compliance, from January 1, 2008 to December 31, 2015, were examined. With trend test using Medication Possession Ratio (MPR), we compared the medical use between the compliant group (MRP≥0.8) and the comparative non-compliant group (0.2≤MPR<0.8). Results: Among 28,095 participants in total, 16,239 patients (57.8%) were diagnosed as schizophrenia; the 30s were the most common (n=7,151, 25.5%). Drug compliance was generally low regardless of the diagnosis and was the lowest among 20s with the 40-60% range of income. The compliant group showed lower psychiatric and medical use than the comparative group in the following years (p<0.0001). Conclusion: These findings suggest that patients in the 20s and 30s with the 40-60% range of income, who are diagnosed with schizophrenia at the first psychiatric visit, may need more clinical and political attention. The results also emphasize the importance of initial drug adherence to antipsychotics in reducing long-term psychiatric costs.

This study firstly examined the socioeconomic and health factors associated with infiltration of private health insurance. Secondly, we compared health behavior, outpatient and inpatient use of private health insured with uninsured. The method of this study is that secondary analysis of the 2008 Korea National Health and Nutrition Survey was conducted for 7178 respondents aged 19 over. We use the logistic regression and t-test for data analysis. The first dependent variable was dichotomy which is divided to private health insured or uninsured and the second dependent variable was the presence and frequency of outpatient and inpatient use. The descriptive variables was gender, age, marital status, income, education, occupation, type of national health insurance, residential area, self confidence of health, prevalence rate of common disease, activity limitation, drinking and smoking status. The result of the major findings are as follows. First, 59 under aged person, married person, people in the higher brackets of income, national employee insured were more likely to infiltrate private health insurance. The poor self confidence of health, activity limitation, person with hypertension or allergic rhinitis and smoker were negatively related in infiltrating private health insurance. Second, private health insured did more preventive behavior such as self-paid health examination, cancer screening, regular exercise than uninsured. Third, private health insured was positively related with the presence of outpatient use and frequency of inpatient use

We developed the hybrid model coupled with predictive model and business rule model for administration of injury by utilizing medical data of the National Health Insurance in Korea. We performed decision tree analysis using data mining methodology and used SAS Enterprise Miner 4.1. We also investigated under several business rule for benefits (expense paid by insurer) and claims of injury in National Health Insurance Corporation. We can see that the proposed hybrid model provides a quite efficient plausible results.

Purpose. The purpose of this study was to analyze the frequency and duration of adjustments after delivery of complete denture according to age, sex, arch with complete denture, insurance coverage of a denture, type of antagonist, the experience of wearing denture, the period of edentulism, and the type of denture base. Materials and methods. For 5 years, medical records of patients aged 65 or older who had treated full dentures were assessed for the frequency and duration of follow-up visits after complete denture delivery. Statistical analysis was performed at the 5% level of significance to analyze the correlation between the frequency and duration of follow-up according to sex, insurance coverage, arch with the complete denture, type of denture base, type of antagonist, experience of wearing a denture, age, and healing period. Results. 247 complete dentures were included in this study. The median frequency of follow-up visits was 3, and the median duration of follow-up was 36 days. Lower dentures had significantly higher frequency of follow-up visits than upper dentures (P = .036). According to the type of antagonist, dentures opposing a complete denture had a significantly higher frequency of follow-up visits than dentures opposing a removable partial denture (P = .016). There was no statistically significant difference in the frequency and duration of adjustments after delivery of complete denture by age, sex, insurance coverage, healing period, the experience of wearing a denture, and type of denture base. Conclusion. Within the limitations of the present study, lower complete dentures or dentures opposing a complete denture had an increased frequency of follow-up visits.

Purpose: This study examined the effects of the postoperative administration of parathyroid hormone (PTH) on fracture healing in intertrochanteric fractures accompanied by osteoporosis in elderly females. Materials and Methods: Female patients aged 65 years and more who underwent surgery after a diagnosis of intertrochanteric fractures and osteoporosis during the period from July 2013 to December 2017 were included as subjects. The subjects were divided into two groups: PTH-treated group and non-PTH-treated group. The formation time of the first callus, timing of the bridging callus, and time of bony union for both groups were evaluated. Results: In the PTH-treated group, the mean time of the first callus formation, average time of bridging callus, and the average time of bony union were 32, 58, 83 days, respectively, which were significantly shorter than that of the untreated group. Conclusion: PTH, a treatment for osteoporosis, promotes callus formation and the healing process. Therefore it will be helpful in intertrochanteric fractures accompanied by osteoporosis in elderly females.
