The purpose of this study was to investigate the current status of unmet medical need using data from the Korea Health Panel study from 2009 to 2013 (excluding 2010), and to analyze the trends of unmet medical need and related factors. The subjects of this study were 11,598 in 2009, 11,035 in 2011, 10,584 in 2012, 10,099 in 2013, and 7,144 people in panel data, and conducted frequency analysis, chi-square test and generalized estimating equation. As a result of the analysis by year, it was found that women, under middle school graduation, medical aid, the lowest household income and low subjective health status experienced more unmet medical need. As a result of analysis using generalized estimating equation, women, under 40 years of age, under elementary school graduation, lowest quartile household income, subjective health status of less than 20 points, and activity restrictions are more likely to experience unmet medical need. Based on these results, we intend to provide basic data for establishing policies on the use of medical services.

Longitudinal data are measured repeatedly over time from the same subject, so there is a correlation from the repeated outcomes. Therefore, when analyzing this correlation, both serial correlation and between-subject variation must be considered in longitudinal data analysis. In this paper, we will focus on the marginalized models to estimate the population average effect of covariates among models for analyzing longitudinal binary data. Marginalized models for longitudinal binary data include marginalized random effects models, marginalized transition models, and marginalized transition random effect models, and in this paper, these models are first reviewed, and simulations are conducted using complete data and missing data to compare the performance of the models. When there were missing values in the data, there is a difference in performance depending on the model in which the data was generated. We analyze Korea Health Panel data using marginalized models. The Korean Medical Panel data considers subjective unhealthy responses as response variables as binary variables, compares models with several explanatory variables, and presents the most suitable model.

This study was aimed to identify factors affecting the purchase of indemnity private health insurance and analyze its effect on healthcare utilization by gender. This study analyzed data of the 2010-2016 Korea Health Panel Survey using panel logit model and panel regression model. Men were less likely to purchase indemnity private health insurance than women. Self-rated health and unmet need for healthcare in women were related to insurance purchases. In men, married people and residents of the metropolitan area were more likely to purchase. The indemnity private health insurance did not affect the women's outpatient expenses per visit, but for men it increased. The indemnity private health insurance significantly increased women's inpatient expenses per admission, but it did not affect men's inpatient expenses. This study confirmed gender differences in the factors affecting the purchase of indemnity health insurance and the impact of indemnity health insurance on healthcare utilization. This suggests that gender differences should be taken into account in private health insurance research and institutional operation.

Background: In recent years, studies have shown conflicting results regarding the benefits of dietary supplements in reducing healthcare expenditures. This study aimed to address this inconsistency by examining the association between supplement consumption and health expenditures using nationally representative data from the Korea Health Panel Survey (2019-2020). Methods: A 1:1 matched case-control dataset was established using propensity score matching technique based on supplement consumption. Then, total annual healthcare expenditures were compared between the two groups. In addition, a multivariate regression analysis (Proc Surveyreg) was performed to determine the association between the supplement consumption and medical costs. Results: The supplement user group spent about 1.72 million Korean won, while the non-user group spent about 1.43 million Korean won on medical services (p=0.0186). The results of multivariate regression showed that the costs were approximately 26.15% higher in the user group than in the non-user group (p=0.0004). Conclusion: Contrary to the previous studies that have shown the benefits of supplement use in reducing healthcare costs, this study showed that those who consistently consumed supplements spent more on medical services. This can be interpreted in the same context as previous studies suggesting that dietary supplement intake is a healthy behavior for managing one's health. However, we caution against drawing firm conclusions due to data limitations. Further analysis using patient-level epidemiologic data is needed.

Purposes: 우리나라 공공의료기관들의 경영실적 보고에 따르면 대부분의 공공의료기관들이 만성적자로 인한 경영난 문제를 겪고 있는 실정이다. 이는 공공의료서비스 제공 등이 주요 원인이겠지만 그럼에도 공공의료기관들의 경영효율화 문제는 지속적으로 지적되고 있음은 공공연한 사실이다. 이에 본 연구는 고정비 성격이 강한 인적자원관리비용과 경영성과 간의 관계를 분석하여 공공의료기관의 경영성과 개선을 위한 경영적 함의를 제공하고자 하였다. Methodology: 분석자료는 2014년부터 2019년까지 39개 지역거점 공공병원의 재무자료를 이용하였고, STATA SE 12.0을 사용하여 다중회귀분석과 패널회귀분석을 실시하였다. Findings: 다중회귀분석을 통한 단면연구 결과에서는 인건비가 높을수록 경영성과가 높은 경향을(2014년 의료수익:1.523/ 2015년 의료수익: 2.002, 의료수익의료이익률: 0.002/ 2016년 의료수익: 1.223) 보였으나 패널회귀분석을 통한 종단연구 결과에서는 복리후생비가 높을수록 경영성과가 의미있게 높은 경향을(의료수익: 3.232582/ 의료수익의료이익률: 0.0014502) 보였다. 이는 인건비는 경영성과에 단기적인 효과가 있는 반면 복리후생비는 경영성과에 장기적인 효과가 있음을 반영하는 것이라고 볼 수 있다. Practical Implication: 본 연구는 이러한 결과를 기반으로 장기적인 효과가 있는 복리후생비의 중요성을 제시하고, 공공의료기관의 경영성과에 영향을 미치는 인건비와 복리후생비의 특성 파악을 통하여 효과적인 인적자원관리방법을 위한 경영적 함의를 도출하였다는 점에서 의의가 있겠다.

The purpose of this study is to analyze outpatients of glaucoma aged 20 or older about their five-year use of ophthalmology and investigate trend of prevalence in glaucoma patients. The Korea Health Panel (KHP) data from 2008 to 2012 were analyzed using frequency and chi-square tests. The outpatients of glaucoma have increased significantly from 0.43% in 2008 to 0.47% in 2009, 0.49% in 2010, 0.61% in 2011, and 0.75% in 2012 (p<0.001). The outpatients of glaucoma are in the 20's to 70's, and higher utility rate is shown in those who are older (p<0.001), and the rate of use tends to increase each year in all the age groups (p<0.001). The medical care utilization attributed to glaucoma in Korea tends to increase lately; therefore, it is a crucial task to realize early detection and management according to the characteristics of different age groups.
