BACKGROUND: The purpose of this study is to estimate empirically whether there is a difference in medical use among income groups, and if so, how much. This study applies econometric model to the most recent year of Korean Medical Panel, 2015. The model consists of outpatient service and inpatient service models. METHODS: The probit model is applied to the model which indicate whether or not the medical care has been used. Two step estimation method using maximum likelihood estimation is applied to the models of outpatient visits, hospital days, and outpatient and inpatient out-of-pocket cost models, with disconnected selection problems. RESULTS: The results show that there was the inequality favorable to the low income group in medical care use. However, after controlling basic medical needs, there were no inequities among income groups in the outpatient visit model and the model of probability of inpatient service use. However, there were inequities favorable to the upper income groups in the models of probability of outpatient service use and outpatient out-of-pocket cost and the models of the number of length of stay and inpatient out-of-pocket cost. In particular, it shows clearly how the difference in outpatient service and inpatient service utilizations by income groups when basic medical needs are controlled. CONCLUSION: This means that the income contributes significantly to the degree of inequality in outpatient and inpatient care services. Therefore, the existence of medical care use difference under the same medical needs among income groups is a problem in terms of equity of medical care use, so great efforts should be made to establish policies to improve equity among income groups.

Establishing a healthcare delivery system is key to building a cost-effective healthcare system that can prevent the waste of healthcare resources and increase efficiency. Recently, the rapid increase in the national medical expenditures due to the aging of the population and the increase in chronic diseases has raised the question about the sustainability of the healthcare system including the health insurance system. This is why we need to reform the medical delivery system, including the function setting of medical institutions. Accordingly, gradual and practical efforts based on the recognition of reality are needed for solving the problems and improving the medical delivery system. The first effort is to secure policy measures to establish functions and roles of medical institutions which are the basis of the healthcare delivery system, and a systematic medical use system for appropriate medical use. This approach can be achieved through a reasonable health insurance schemes. Without reasonable reform efforts, it will be difficult for Korea's health care system to develop into a system that can provide cost-effective and high-quality medical services that the people want.

Objectives: De-identifying protected health information (PHI) in medical documents is important, and a prerequisite to deidentification is the identification of PHI entity names in clinical documents. This study aimed to compare the performance of three pre-training models that have recently attracted significant attention and to determine which model is more suitable for PHI recognition. Methods: We compared the PHI recognition performance of deep learning models using the i2b2 2014 dataset. We used the three pre-training models—namely, bidirectional encoder representations from transformers (BERT), robustly optimized BERT pre-training approach (RoBERTa), and XLNet (model built based on Transformer-XL)—to detect PHI. After the dataset was tokenized, it was processed using an inside-outside-beginning tagging scheme and WordPiecetokenized to place it into these models. Further, the PHI recognition performance was investigated using BERT, RoBERTa, and XLNet. Results: Comparing the PHI recognition performance of the three models, it was confirmed that XLNet had a superior F1-score of 96.29%. In addition, when checking PHI entity performance evaluation, RoBERTa and XLNet showed a 30% improvement in performance compared to BERT. Conclusions Among the pre-training models used in this study, XLNet exhibited superior performance because word embedding was well constructed using the two-stream self-attention method. In addition, compared to BERT, RoBERTa and XLNet showed superior performance, indicating that they were more effective in grasping the context.

The objective of this study is to provide basic information and policy implications needed to balance the supply and demand for dietitian by projecting supply and demand for dietitian. The data from the Ministry of Health Welfare and Family on the number of licensed nutritionist, resident registration data of the Ministry of Public Administration and Security, and health insurance qualification data of the National Health Insurance Corporation were used to examine the current status of supply. To project the supply of nutritionist workforce, the in-out moves method and demographic method were used. The ratios of nutritionist to population and GDP, and that of other countries were applied as the demand projection method. According to the study results, the projection on the imbalance of supply and demand for dietitian by year 2021 differs depending on the method used. First, according to the results based on age-adjusted population ratio, there is an oversupply of 1,643 dietitians in year 2010, and 2,076 dietitians in year 2020. Second, although the projection on the imbalance of the supply and demand for dietitian differs depending on whether the GDD is calculated in won(won) or dollar($). it is expected that there will be an oversupply in general. Third, as to the scenario using the nutritionist ratio in foreign countries, the oversupply of dietitian is likely in Korea, under any scenario, when comparing the nutritionist supply projection with the demand projection based on the nutritionist ratio in the United States. However, the projection of the supply and demand varies in each scenario when the European nutritionist ratio is applied. Under European 'scenario 1', an oversupply is expected, whereas under 'scenario 2', a shortage of supply is expected. A careful approach is required in interpreting the supply and demand projection using criteria of other countries, because dietitian assumes different roles and functions in each country. Although a slight oversupply of nutritionist workforce is projected, it does not cause a major problem as the demand for diet therapy is expected to rise due to aging and the increase of chronic diseases, and as the demand for clinical dietitians in hospitals increases. Accordingly, the demand for dietitians will rise and, in this context, the oversupply of nutritionist will not incur much problem. However, the nutritionist qualification is much too open in Korea, and this has a negative effect on the quality of the nutritionist workforce. Therefore, it is important that the nutritionist qualifications and requirements are reinforced in the future, enhance the quality level of the nutritionist supply, and maintain the balance between the supply and demand.

PURPOSE: The purpose of this study is to enhance the quality of data by performing a methodological assessment of medical records reviews. METHODS: We reviewed the articles published in the Journal of the Korean Society of Emergency Medicine between January 2001 and December 2003 that used a retrospective medical records review as the study method. We assessed data collector's training, descriptions of inclusion/ exclusion criteria, definitions of important variables, use of standardized case record forms, monitoring the data collectors' performance, blind data collecting, inter-rater reliability/ test of inter-rater agreement, intra-rater reliability/test of intra-rater agreement, selection bias from consent, and rules regarding management of missing data. RESULTS: There were 111 articles that used retrospective medical records reviews during the study period. In 111 (100%) articles, inclusion/exclusion criteria were described, in 98 (88.3%), important variables were defined, and in 4 (3.6%), standardized case record forms were used. However no articles addressed the other items on the checklist. CONCLUSION: Study conductors should design studies to enhance the quality of data, and detailed descriptions are necessary to improve the reproducibility of the study.

PURPOSE: The purpose of this study was to assess the statistical methods used in the Journal of the Korean Society of Emergency Medicine (JKSEM) and to identify the types of errors in statistical analysis. METHODS: We reviewed quantitative articles that were published in the JKSEM from January 1998 through December 2002. Editorials, review articles, and case reports were not included in this analysis. A total of 319 articles was reviewed. We focused on the methods of inferential statistics in these articles. We evaluated the adequacy and the validity of the statistical techniques with our criteria, which were established by modifying Ahn's checklist. RESULTS: Of the 319 articles, 222 used inferential statistics. The t-test was the statistic of choice overall (45.1%), followed by the chi-square test (23.9%). Errors of omission (70.3%) were more frequent than errors of commission. Of the errors of omission, incomplete description of the basic data was the most common. CONCLUSION: We found various mistakes or misuses in the applications of statistical methodologies in the articles published in the JKSEM. The present study suggests that additional efforts should be focused on the appropriateness of the statistical analysis used in JKSEM articles to improve their value, and during the review process, editorial attention should be paid to the validity of the statistical methodologies used in the articles.

PURPOSE: Unrefined tablets prepared from Aconitum tubers are occasionally used in Korean folk medicine. This study defines the potential sources, clinical toxicology, and treatment of aconitine poisoning. METHODS: A retrospective survey was conducted in 63 patients in the ED of a tertiary University Hospital with suspected toxicity from an unrefined tablet prepared from Aconitum tubers from 1999 to 2007. RESULTS: A total of 63 cases enrolled included 26 men and 37 women, aged 30 to 86 years. Forty-eight patients ingested aconitine tablets as digestives, 26 tablets on average. After a latent period of 30 to 450 minutes, patients developed a combination of neurologic (87.3%), gastrointestinal (82.5%), cardiopulmonary (41.3%), and other (28.6%) features typical of aconitine poisoning. Initial ECG abnormalities revealed dysrhythmia (61.9%), conduction disturbance (42.9%), and abnormal waveforms (39.7%), with 28.6% of patients having normal ECGs. All patients received supportive treatment or close observation regardless of ingestion amounts. Patients with hypotension or ventricular arrhythmia were treated with inotropic agents or amiodarone. CONCLUSION: Toxicologic signs and symptoms can occur after the consumption of aconitine tablets, regardless of ingestion amount. The risk occurs because of inadequately processed aconitine roots. This study will provide important data for public education and distribution regulations for Aconitum sp. in Korea.
