BACKGROUND: Medical Aid (MA) beneficiaries, belonging to low-income and vulnerable groups, tend to utilize more healthcare services than patients covered by general health insurance. This study aimed to investigate shifts in medical expenses among South Korean MA beneficiaries from 2010 to 2020 in response to changes in health coverage. METHODS: This study was a retrospective cohort study that involved analyzing data from 354,289 MA beneficiaries aged 20 years and older as of 2010 whose healthcare utilization data could be tracked up to 2020. The impact of changes in health coverage of MA beneficiaries on the increase in medical expenses was analyzed with multiple logistic regression analysis. RESULTS: The findings revealed that the group maintaining their MA eligibility had a higher rate of increase in medical expenses compared to those transitioning from MA to National Health Insurance (NHI). Even after adjusting for covariates, the likelihood of an increase in total annual medical expenses was more than 1.4 times higher for the MA maintenance group. However, the group that maintained MA also had higher initial healthcare expenses, indicating poorer health status, compared to the group that transitioned to NHI. CONCLUSION In the public healthcare domain, such as MA, it is crucial to enhance access to necessary healthcare services while preventing unnecessary medical treatments. There is a need for systemic improvements to ensure that low-income, medically vulnerable groups can appropriately use the healthcare services they require to achieve high-value health outcomes.

Pneumoconiosis, an interstitial lung disease that occurs from breathing in certain kinds of damaging dust particles, is a major occupational disease in China. Patients diagnosed with occupational pneumoconiosis can avail of free medical treatment, whereas patients without a diagnosis of occupational diseases cannot not claim free medical treatment in most provinces from the government before 2019. This study aimed to analyze the priority of medical facility selection and its influencing factors among patients with pneumoconiosis. A total of 1,037 patients with pneumoconiosis from nine provinces in China were investigated. The health service institutions most frequently selected by the patients were county-level hospitals (37.5%). The main reason for the choice was these hospitals' close distance to the patients' homes (47.3%). The factors for the choice of health care institutions were living in the eastern region (

BACKGROUND: Health policies in the Philippines have evolved in response to increasing health demands of older adults. However, there is a lack of research on equity among the ageing population in low-middle income countries. The objective of this study was to identify the trends in National Health Insurance Program (NHIP) coverage and healthcare utilization among older adults in the Philippines for the period from 2003 to 2017, during which NHIP expansion policies were implemented, focusing on reductions in socio-economic inequalities. METHODS: A literature search of policies for older adults and an analysis of four Philippine National Demographic and Health Surveys (2003, 2008, 2013, and 2017) with data from 25,217 older adults who were 60 years or older were performed. The major outcome variables were NHIP coverage, self-reported illness, outpatient healthcare utilization, and inpatient healthcare utilization. Inequalities in NHIP coverage and healthcare utilization according to wealth were evaluated by calculating the concentration index for individual years, followed by a regression-based decomposition analysis. RESULTS: NHIP coverage among older adults increased from 9.4 (2003) to 87.6% (2017). Although inequalities according to wealth quintile were observed in all four surveys (all P < 0.001), the concentration index declined from 0.3000 (2003) to 0.0247 (2017), showing reduced inequalities in NHIP coverage over time as observed for self-reported illness and healthcare utilization. NHIP coverage expansion for older adults in 2014 enabled equal opportunity for access to healthcare. CONCLUSION The passage of mandatory NHIP coverage for older Filipino adults in 2014 was followed by a reduction in inequality in NHIP coverage and healthcare utilization according to wealth.

fertilization and embryo transplantation (IVF-ET) technology is one of the main treatments for infertility. But IVF-ET is expensive and has not be covered by health insurance in most developing countries. Therefore, how to obtain the maximum success rate with the minimum cost is a common concern of clinicians and patients. At present, the economic studies on IVF-ET mainly focus on different ovulation stimulating drugs, different ovulation stimulating protocols, different transplantation methods and the number of transplants. But the process of IVF-ET is complex, the relevant methods of economic study are diverse, and there are no unified standard for outcome indicators, so there is no unified conclusion for more economical and effective protocol by now. Therefore, to analyze the economic studies of IVF-ET, and to explore appropriate evaluation methods and cost-effective protocols will be helpful for reasonable allocation of medical resources and guidance of clinical selection. It would provide policy reference to include the costs of IVF-ET treatment in health insurance in the future.

BACKGROUND: This study aimed to analyze correlations between depression, cognitive function, oral health state, ability to perform activities of daily living, oral dryness symptoms, and oral health-related quality of life, and determine factors influencing the latter.METHODS: This was a cross-sectional study based on questionnaires completed by 260 participants with suspected dementia, residing in South Korea. Psychiatrists, psychiatric nurses, and dental hygienists visited clinics in the participating regions for examination and questionnaire administration. General characteristics, the geriatric depression scale, ability to perform activities of daily living, cognitive function, oral health state, and oral health-related quality of life were analyzed. Independent t-tests, one-way analysis of variance (ANOVA), correlation analysis and multiple regression analysis were conducted, identifying factors affecting oral health-related quality of life. Data analysis was performed using SPSS ver. 20.0 (IBM Corp., USA), and the significance was set at p<0.05.RESULTS: Approximately 65.0% of participants were female, 63.5% were in their 70s, and 90.0% had health insurance. About 21.5%, 42.0%, and 36.5% were normal, slightly impaired, and had dementia, respectively. High cognitive impairment was associated with poor oral health. Sex, education levels, marital status, and living arrangements influenced oral health-related quality of life. According to the regression analysis, geriatric depression and oral dryness affected the Geriatric Oral Health Assessment Index scores.CONCLUSION: In conclusion, oral dryness and depression levels among elders influenced oral health-related quality of life. The results showed that to enhance elders' oral health-related quality of life, it is essential to not only improve their oral health state, but also relieve oral health problems, especially oral dryness, and take into consideration their psychological aspects.

OBJECTIVES: This study was performed to examine the effects of the public attention to ‘crime of schizophrenia’ on the use of mental health services in patients with schizophrenia using big data analysis. METHODS: Data on the frequency of internet searches for ‘crime of schizophrenia’ and the patterns of mental health service utilization by patients with schizophrenia spectrum disorders by month were collected from Naver big data and the Health Insurance Review and Assessment Services in Korea, respectively. Their correlations in the same and following month for lagged effect were examined. RESULTS: The number of outpatients correlated negatively with public attention to ‘crime of schizophrenia’ in the same month. The lagged relationship between public attention and the number of admissions in psychiatric wards was also found. In terms of sex differences, the use of outpatient services among female patients correlated negatively with public attention in the same month while the number of male patients' admissions in both same and following month correlated positively with public attention. CONCLUSION: These findings suggested that public attention to ‘crime of schizophrenia’ could negatively affect illness behavior in patients with schizophrenia.

Health insurance big data not only provide real-world evidence of unmet needs in actual clinical practice but also of breakthroughs in the medical industry which will shape the future of health care. Big data are also expected to transform the existing medical paradigm and provide a truly personalized medical age. However, questions about research through the collection and utilization of various big data in various fields have also been raised because quality limitations cannot be overlooked. Therefore, many challenges remain to be overcome in the use of big data research as a basis for changing medical practice. Intervention and interpretation by clinical medical experts are required in judging the scientific trustworthiness of the big data analysis process and the validity of the results. Therefore, healthcare big data research cannot achieve its goal by the efforts of researchers alone. Teams of data analysis scientists, epidemiologists, statistics experts, and clinical researchers are required to collaborate closely with team members, from the design phase to expert consultation, through regular meetings. In addition, it is necessary, in the creation of a healthier community, to cooperate with government agencies that provide data based on the whole nation or the world's population, as well as interest groups representing the people, and policy-making organizations. In this paper, we describe the knowledge, practical clinical applications, and future research directions and prospects for the next phase of health care, from the design of clinical research using health insurance big data to report writing.

To analyze the equity of outpatient service utilization for hypertensive patients (HPs) under 3 kinds of social medical insurance, and to explore its influential factors.
 Methods: A total of 8 670 HPs (aged at 15 years old from 28 sub-centers) in 14 provinces were selected. Indirectly standardized method and concentration index were used to analyze the equity of outpatient utilization in HPs, and decomposition analysis was used to explore the impact factors of outpatient treatment among the whole sample population, population with urban employees' basic medical insurance (UEBMI), and population with urban residents' basic medical insurance (URBMI) and new rural cooperative medical systems (NCMS).
 Results: The overall concentration index (CI) for the whole sample population was 0.2378. After the standardizing "need" variable, horizontal inequity (HI) was 0.2360, indicating that the outpatient service of HPs was inequity and that the higher economic level, the more outpatient services received. The decomposition of overall CI results showed that the positive factors for contribution were gross domestic product (GDP) level, retired, UEBMI and URBMI, and the negative factors for contribution were NCMS. The CI of UEBMI, URBMI and NCMS was 0.2017, 0.1208 and 0.0288, respectively; the HI was 0.1889, 0.1215 and 0.0219, respectively. The inequity in UEBMI is the most serious, followed by NRCMS and URBMI. The economic level was the main factor that caused inequity in the outpatient services utilization in three social medical insurance. In addition to the economic level, a common positive factor for the contribution to UEBMI and URBMI was district of residence, and the age was the positive factor to UEBMI as well.
 Conclusion: There are different levels of inequity in the HPs covered by 3 kinds of social medical insurance, and the inequity of UEBMI is the highest one among 3 kinds social medical insurance. The economic level is the main factor that affects the equity of outpatient in the HPs under 3 kinds of social medical insurance.

BACKGROUND: Previously, surveys have been used to investigate breast reconstruction statistics. Since 2015, breast reconstruction surgery after mastectomy has been covered by the National Health Insurance Service in Korea, and data from breast reconstruction patients are now available from the Health Insurance Review and Assessment Service (HIRA). We investigated statistics in breast reconstruction in Korea through statistics provided by the HIRA Big Data Hub. METHODS: We investigated the number of cases in mastectomy and breast reconstruction methods from April 1, 2015 to December 31, 2016. Data were furnished by the HIRA Big Data Hub and accessed remotely online. Results were tabulated using SAS Enterprise version 6.1. RESULTS: The 31,155 mastectomy cases included 7,088 breast reconstruction cases. Implant-based methods were used in 4,702 cases, and autologous methods in 2,386. The Implant-based reconstructions included 1,896 direct-to-implant and 2,806 tissue-expander (2-stage) breast reconstructions. The 2-stage tissue-expander reconstructions included 1,624 expander insertions (first stage) and 1,182 expander-to-permanent-implant exchanges (second stage). Of the autologous breast reconstructions, 705 involved latissimus dorsi muscle flaps, 498 involved pedicled transverse rectus abdominis myocutaneous (TRAM) flaps, and 1,183 involved free-tissue transfer TRAM flaps, including deep inferior epigastric perforator free-tissue transfer flaps. There were 1,707 nipple-areolar complex reconstructions, including 1,565 nipple reconstructions and 142 areola reconstructions. The 1-year mean number of breast reconstructions was 4,050. CONCLUSIONS: This was the first attempt to evaluate the total number of breast reconstruction procedures using accurate, comprehensive data, and our findings may prove valuable as a foundation for future statistical studies of breast reconstruction procedures in Korea.

PURPOSE: Parenteral nutrition (PN) is known to provide therapeutic beneficial improvements in malnourished patients for whom enteral nutrition is not feasible. The objective of this study was to investigate the current clinical characteristics and utilization of PN in Korea. METHODS: We analyzed the Health Insurance Review Agency National Inpatients Sample database from 2014 to 2016, which included 13% of all hospitalized patients in Korea. Adult patients aged 20 years or older and receiving premixed multi-chamber bag containing PN were included for this study. Patient characteristics, admission type, primary diagnosis, and hospital demographics were evaluated. SAS version 9.4 was used for data analysis. RESULTS: From 2014 to 2016, 149,504 patients received premixed PN, with 226,281 PN prescriptions being written. The mean patient age was 65.0 years, and 81,876 patients (54.8%) were male. Premixed 3-chamber bag and 2-chamber bag PN solutions were utilized in 131,808 (88.2%) and 32,033 (21.4%) patients, respectively. The number of patients hospitalized through the emergency department were 70,693 (47.3%), whereas 43,125 patients (28.8%) were administered PN in intensive care units. In the adult PN patients, the highest primary diagnosis was malignant neoplasm of the stomach (8,911, 6.0%), followed by organism unspecified pneumonia (7,008, 4.7%), and gastroenteritis and colitis of unspecified origin (6,381, 4.3%). Overall, 34% of adult PN patients were diagnosed with malignancies, the most common being neoplasm of the stomach (17.7%), neoplasm of bronchus/lung (11.2%), neoplasm of colon (11.1%), and neoplasm of liver/intrahepatic bile ducts (10.0%). PN solutions were most frequently administered in the metropolitan area (55.0%) and in hospitals with more than 1,000 beds (23.6%). CONCLUSION: PN was commonly administered in older patients, with primary diagnosis of malignancy in a significant number of cases. This study is the first large-scale description of PN-prescribing patterns in real-world clinical practice in South Korea.
