The purpose of this study was to investigate the determinants of total payment for mental and behavioral disorders patients admitted through the emergency room. Study data was selected from the Korean National Health Insurance sample data in 2009. This data was consisted of 753 inpatients who are 331 inpatients with only main sick(F31-F39) and 422 inpatients with main sick codes(F31-F39) and sub sick(F00-F99) admitted through the emergency room. SPSS v.18 was used for the statistical analysis such as descriptive analysis, t-test, ANOVA, and multiple regression analysis. In multiple regression analysis, significant variables affecting total payment of main sick patients were gender(p<.01), treatment result(p<.001), path of the emergency room(p<.001), and length of stay(p<.001). Also, main sick patients with sub sick were gender(p<.01), age(p<.001), treatment result(p<.001), path of the emergency room(p<.001), and length of stay(p<.001). These findings implied that it is necessary to build short, middle, and longterm program and system for high risk mental and behavioral disorders groups.

The purpose of this study was to investigate pediatric emergency department visits patterns and characteristics of children and adolescents under the age of 20 in South Korea from 2002 to 2015 due to dental conditions. This study used a stratified sample of approximately 1 million people from the Health Insurance Review and Assessment Service Database. The age, region, household income, and treatment cost were included for the patient characteristic analysis. Pediatric patients were compared to the adult group (over 20 years old). In children and adolescents, the rate of emergency department visits due to dental conditions was higher for traumatic conditions than for non-traumatic conditions. Children and adolescents with higher household income visited the emergency department more often than those with lower household income. The region with the highest number of children and adolescents visiting the emergency department for dental conditions was Busan (per 100,000 population). Although this study could not confirm the annual trend of children and adolescents' dental emergency visits due to the sample size limitation, the characteristics of children and adolescents' dental emergency visits were compared with those of adults using a stratified sample.

The purpose of this study was to analyse the relationship between the characteristics of the patients who received oral antihyperglycemic drugs and their medical adherence in Korea. The study method was a cross-sectional study using the patient sample data of the Health Insurance Review and Assessment Service for 2016, and it was analyzed with 109 major components of diabetes drug. The medical adherence was slightly higher in male than female. The patriots & veterans(free) type had the highest medication adherence because they have low self burden to access medical institutions compared to other insurance types. It is expect that this study result will be used as a basic data to understand the burden of outpatients with health insurance and establish a policy to reduce of the self outpatients' burden with chronic diseases such as type 2 diabetes.

In this study, we analyzed situation and length of stay(LOS) variations of inpatients with pressure ulcer using patient safety indicators developed by the United States Agency for Healthcare Research and Quality(AHRQ) and proposed management of medical quality and development of policy. The dataset was taken from 1,373 database of the hospital discharge injury survey from 2005 to 2008. Analysis method was used frequency and chi-square test, ANOVA, multiple linear regression analysis. In result, distribution of inpatients with pressure ulcer by sex were 52.5%(male), 47.5%(female), respectively and aged $65{\geqq}years$ was the highest in age group. LOS of inpatients with nervous system principal disease was the longest. Independent variables which were statistically associated with LOS of inpatients with pressure ulcer were year, sex, insurance type, bed size, operation, principal diagnosis. Therefore, hospital should develop the standardized strategy and guidelines to manage pressure ulcer inpatients efficiently and apply it into the medical information system.

In this paper, the 1.24 million elderly patient medical data (HIRA-APS-2014-0053) provided by the Health Insurance Review and Assessment Service and weather data are analyzed with generalized estimating equation (GEE) model and long short term memory (LSTM) based recurrent neural network (RNN) model to predict the number of disease occurrence. To this end, we estimate the patient's residence as the area of the served medical institution, and the local weather data and medical data were merged. The status of disease occurrence is divided into three categories(occurrence of disease of interest, occurrence of other disease, no occurrence) during a week. The probabilities of categories are estimated by the GEE model and the RNN model. The number of cases of categories are predicted by adding the probabilities of categories. The comparison result shows that predictions of RNN model are more accurate than that of GEE model.

This study aimed to investigate the frequency of dental visits after coronavirus disease 2019 (COVID-19) in children and adolescents in comparison to that of adults. The data on the number of dental visits on the basis of different classification and treatment codes for all the age groups were provided by the Health Insurance Review and Assessment Service from January 2017 to December 2020. To reduce the impact of the population change, dental visits per 1000 people was used. After the start of the pandemic, dental visits per 1000 people decreased in all age groups when analyzed for the diseases of pulp and periapical tissues classification code and dental visits per 1000 people decreased over 5 years age groups when analyzed for the pulp treatment code. Regarding the restorative treatment code, visits in the 0 - 19 years age group decreased after the pandemic. Based on the comparison of the number of confirmed COVID-19 cases to that of monthly dental visits by treatment codes, the change rate of pulp and restorative treatments gradually decreased after the waves of the pandemic in February and August 2020 in Korea. Furthermore, dental visits per 1000 people for gingivitis and periodontal disease classification code increased after the pandemic in all age groups. The rate of decrease in dental visits per 1000 people for restorative treatments in children and adolescents was higher than that in adults. The rate of decrease in the number of dental visits for multi-visit pulp treatments showed a rapid decrease as compared to that of 1-visit pulp treatments after the pandemic. This study identified changes in the number of dental visits of children and adolescents after COVID-19 transmission in comparison to that observed in adults.

Background : The principal diagnosis has been used in many different fields such as hospital statistics, medical research, insurance claim, national health statistics and so on. Some principal diagnoses have a relatively low level of reliability in the medium-sized hospitals. The purpose of this study is to identify the reliability level of principal diagnoses and to suggest ways to improve reliability of the principal diagnosis. Method : Data were collected from a medium-sized hospital located in Pusan. The discharge summaries on 323 patients who were discharged in January, 2008 and the outpatient summaries on 251 patients who visited the hospital on March 28, 2008 were collected, and descriptive analysis was performed using SPSS version 12.0K. Result : The findings are the followings: (1) the diagnostic consistency rate between medical records and doctors' was 92.0%; (2) the diagnostic consistency rate between medical records and insurance claims was 86.1%; (3) the diagnostic consistency rate between doctors' diagnoses and insurance claims was 80.2%. The evidence seems to indicate that some principal diagnoses have reliability problems in the medium-sized hospitals. Conclusion : The results of this study suggest the followings: (1) employees should be trained and supervision of hospital activities are needed; (2) network systems should be constructed for each department; (3) professions need to be fostered (4) doctors' awareness of medical records should be changed.

This paper examines the level of the primary care continuity for patients with high blood pressure and the effects of the primary care continuity on their convergence health outcomes. We conducted a retrospective cohort study. A total of 315,791 patients who had received new diagnoses of hypertension. We determined standard indices of continuity of care-MFPC, MMCI, and COC and evaluated their association with study outcomes over three years of follow-up. Outcome measures included hospitalization and emergency room visits. The result of the primary care continuity levels and hazard ratios of health outcome showed that, comparing continuity group, non-continuity group had higher rates of hospitalization by 1.655(95% CI: 1.547-1.771) and emergency room visits by 1.669(95% CI: 1.465-1.903). This paper argues that medical costs of chronic diseases will reduce if low continuity of care turns into high continuity of care.
