Background:
As the government has recently been discussing the expansion of the disaster health expenses support project, we would like to confirm the characteristics of beneficiaries of the support project, particularly those of high-cost beneficiaries.
Methods:
Using the database of catastrophic health expenditure support project from 2019–2020, this study aims to confirm the characteristics of high-cost beneficiaries focusing on the overlap of the relieved out-of-pocket systems, known as the out-of-pocket ceiling system and the system for rare incurable diseases. Logistic regression analysis is used to examine this issue.
Results:
In order to analyze the factors influencing high-cost beneficiaries, five models were created and analyzed, including the status of duplicated beneficiaries for relieved out-of-pocket systems, sociodemographic and economic factors, and individual health status as sequential independent variables. All five models were statistically significant, of which economic factors had the greatest impact on the model’s predictions. The main results indicated that those who benefited from multiple systems in duplicate were more likely to be high-cost beneficiaries, and there is a higher probability of incurring high health expenses among the underage. In addition, within the beneficiaries of catastrophic health expenditure support project, it was observed that higher health insurance premium percentiles are associated with a higher proportion of high-cost beneficiaries.
Conclusion
This study examined the characteristics of high-cost beneficiaries by encompassing reimbursement and nonreimbursement. According to this study, it is expected to be used as basic data for setting priorities and improving the current criteria of catastrophic health expenditure support project, aiming to sequentially expand the program.

Background:
As the population is aging, chronic diseases and depression are becoming the main problems in a country’s healthcare system. In this study, we aimed to explore the associations between chronic diseases and depression among the elderly in South Korea.
Methods:
We analyzed 9,975 (men, 4,147; women, 5,828) respondents obtained from the 2014 National Survey of Living Conditions and Welfare Needs of Korean Older Persons. Our dependent variable was either 1 or 0 according to whether a respondent had depression or not, where depression was defined when the Short Form of Geriatric Depression Scale score was 8 or more points. Variables of interest were 24 types of chronic diseases and covariates included various socio-demographic and health behavior characteristics. We performed Rao-Scott chi-square tests and hierarchal logistic regression analyses by gender, reflecting the characteristics of the survey.
Results:
A significant difference was found in the proportion of having depression between genders (men 18.9% vs. women 23.4%). According to fully adjusted, multivariable analyses, for elderly men, relative to those without any chronic disease, the odds ratio of depression was 1.56 (95% confidence interval [CI], 1.10–2.22) in the stroke patients group and 1.82 (95% CI, 1.01–3.25) in the osteoporosis patients group. For elderly women, the odds ratio was 1.96 (95% CI, 1.28–3.00) in the fracture/dislocation and aftereffects patients group and 1.30 (95% CI, 1.03–1.64) in the group of patients with other diseases.
Conclusion
Even after being adjusted for diverse characteristics, some chronic diseases were significantly associated with depression in the elderly and the association differed between genders. Therefore, public health and medical interventions are needed to manage such chronic diseases together with curing depression symptoms.

OBJECTIVES: The purpose of this study was to estimate the willingness to quit cigarette price among Korean male adults, and to examine he factors affecting the willingness to quit cigarette price. METHODS: The data was collected by a random digit dial telephone survey. 702 samples were analyzed by using ttests, ANOVA and OLS regression analysis. To estimate the willingness to quit cigarette price, smokers were asked dichotomous questions with open-ended follow-up and the starting point of the price was randomized by one of 5 bid prices elicited from a pilot study. RESULTS: The mean of the willingness to quit cigarette price was 4,287 Won per package, which was about 2,000 Won higher than the mean of the actual price the smokers now paid. About 41% of respondents were willing to quit smoking if the price of cigarette would be increased by 3,000 Won, and if the price would be increased by 20,000 Won, all respondents were willing to quit smoking. The factors associated with the willingness to quit cigarette price were the place of residence, the amount of smoking and the degree of exposure to smoking through the mass media. CONCLUSIONS: The results showed that to get people to quit smoking, increasing the cigarette price would obviously be effective and much higher prices have a greater effect. Furthermore, to enlarge the effect of increased cigarette prices, providing more cessation programs to small towns, reducing the amount of smoking and decreasing or prohibiting advertisements of cigarettes and smoking in the mass media will be efficient.

OBJECTIVES: To determine the impact of cigarette prices on the decision to initiate and quit smoking by taking into account the interdependence of smoking and other behavioral risk factors. METHODS: The study population consisted of 3,000 male Koreans aged > or =20. A survey by telephone interview was undertaken to collect information on cigarette price, smoking and other behavioral risk factors. A two-part model was used to examine separately the effect of price on the decision to be a smoker, and on the amount of cigarettes smoked. RESULTS: The overall price elasticity of cigarettes was estimated at -0.66, with a price elasticity of -0.02 for smoking participation and -0.64 for the amount of cigarettes consumed by smokers. The inclusion of other behavioral risk factors reduced the estimated price elasticity for smoking participation substantially, but had no effect on the conditional price elasticity for the quantity of cigarettes smoked. CONCLUSIONS: From the public health and financial perspectives, an increase in cigarette price would significantly reduce smoking prevalence as well as cigarette consumption by smokers in Korea.

Purpose:
Although various treatment regimens have been introduced for hepatocellular carcinoma (HCC) accompanied by portal vein tumor thrombosis (PVTT), comprehensive and direct comparisons between them are limited. Thus, the purpose of this study was to perform a network meta-analysis (NMA) to compare the efficacies of different treatment regimens for HCC accompanied by PVTT.
Methods:
A systematic review was conducted to identify studies comparing 2 or more treatment regimens for HCC accompanied by PVTT without extrahepatic metastasis and reporting each overall survival (OS). Endpoints of this NMA were to hazard ratios with confidential intervals for OS and mean survival time difference of each treatment regimen comparison using a random-effects model. Each treatment regimen was then ranked using the P-score to assess the probability of the superiority of each one.
Results:
Eleven studies involving 1,623 patients that yielded 16 comparisons were identified and enrolled in this NMA. There were 12 different treatment regimens as comparators, including sorafenib therapy alone (reference treatment).The NMA suggested that the following 4 treatment regimens improved OS compared to sorafenib: surgical resection followed by portal vein chemotherapy (SR plus PVC), SR, radiofrequency ablation plus sorafenib, and transarterial chemoembolization combined with selective internal radiation therapy. SR plus PVC was ranked the best treatment regimen for OS (P-score, 93.9%).
Conclusion
Comparative efficacy based on this NMA may help clinicians select treatment for HCC accompanied by PVTT. If amenable, aggressive locoregional treatment regimens such as SR plus PVC should be considered for HCC accompanied by PVTT.

Background:
The purpose of this study is to analyze whether there is a change in patterns of medical use among those likely to be converted their health insurance qualifications when the family support rule is alleviated. There is no empirical analysis that converting health insurance qualification will affect the increase in medical use.
Methods:
For analysis, data were extracted from the national health insurance eligibility and medical care database. To identify analysis targets similar to that of medical aids’ characteristics among health insurance coverage, we compared income, property level, and medical use patterns through basic statistical analysis and used a difference-in-difference (DID) analysis to estimate the net effect of changes in medical use following the change of qualifications.
Results:
The main results are as follows. The results show that those who are under the 5% income group (1st income group) of health insurance coverage are the most similar to the medical aids group. DID analysis shows that changes in the medical use of people who maintain their national insurance qualification and who are not. As a results, the number of hospitalized days of converting group was reduced by 3.5 days while outpatient days were increased by 1.8 days.
Conclusion
As a result, there was not much difference in the patterns of medical use for the under 5% income group who are likely to be eligible for expanded medical aids when the family support rule is alleviated. In addition, more than 30% of them are in arrears with their health insurance premiums, causing inconvenience in using medical services. These findings suggest the need of abolishing the criteria obligated to support family, and great efforts should be made to contribute to non-paid poor and remove their medical blind spot.

OBJECTIVES: The study is investigated socioeconomic variations in self-rated health status and contribution of health behavioral factors in Korea. METHODS: A nationally representative sample (2,800 men and 3,230 women aged 20-64 years) from the 2005 Korea National Health and Nutrition Surveys was analyzed using logistic regression. RESULTS: Self-rated health was lower among lower socioeconomic groups compared with higher socioeconomic groups, with gender being irrelevant. This association was attenuated when health behavioral and socio-demographic factors were adjusted. When each health behavioral factor was considered separately, mediators such as smoking in men, and stress or exercise in women explained a large part of the decreased socioeconomic health inequalities. CONCLUSIONS: In Korea, subjective health inequalities arise from different socioeconomic status, but this difference is decreased by health behavioral factors. Therefore, socioeconomic inequity in self-rated health status can be corrected more effectively by promotional health behaviors.

Background:
Quantitative evaluation of renal cortical echogenicity (RCE) has been tried anddeveloped in human and veterinary medicine.
Objectives:
The objective of this study was to propose a method for evaluating RCEquantitatively and intuitively, and to determine associations between ultrasonographic renalstructural distinction and estimated glomerular filtration rate (eGFR) in canine chronickidney disease (CKD).
Methods:
Data were collected on 63 dogs, including 27 with normal kidney function and 36CKD patients. Symmetric dimethylarginine and creatinine concentrations were measuredfor calculating eGFR. RCE was evaluated as 3 grades on ultrasonography images accordingto the distinction between the renal cortex and outer medulla. The RCE grade of each kidneywas measured.
Results:
There was a significant difference in eGFR between the group normal and CKD (p< 0.001). As mean of RCE grades (the mean values of each right and left kidney's RCE grade)increases, the proportion of group CKD among the patients in each grade increases (p <0.001). Also, severity of RCE (classified as "high" if any right or left kidney evaluated as RCEgrade 3, "low" otherwise) and eGFR is good indicator for predicting group CKD (p < 0.001).
Conclusions
The degree of distinction between the renal cortex and the outer medulla isclosely related to renal function including eGFR and the RCE grade defined in this study canbe used as a method of objectively evaluating RCE.

Background:
Postoperative atrial fibrillation (A-fib) is a serious complication of cardiac surgery that is associated with increased mortality and morbidity. Traditional 24-hour Holter monitors have limitations, which have prompted the development of innovative wearable electrocardiogram (ECG) monitoring devices. This study assessed a patch-type wearable ECG device (MobiCARE-MC100) for monitoring A-fib in patients undergoing cardiac surgery and compared it with 24-hour Holter ECG monitoring.
Methods:
This was a single-center, prospective, investigator-initiated cohort study that included 39 patients who underwent cardiac surgery between July 2021 and June 2022.Patients underwent simultaneous monitoring with both conventional Holter and patchtype ECG devices for 24 hours. The Holter device was then removed, and patch-type monitoring continued for an additional 48 hours, to determine whether extended monitoring provided benefits in the detection of A-fib.
Results:
This 72-hour ECG monitoring study included 39 patients, with an average age of 62.2 years, comprising 29 men (74.4%) and 10 women (25.6%). In the initial 24 hours, both monitoring techniques identified the same number of paroxysmal A-fib in 7 out of 39 patients. After 24 hours of monitoring, during the additional 48-hour assessment using the patch-type ECG device, an increase in A-fib burden (9%→38%) was observed in 1 patient.Most patients reported no significant discomfort while using the MobiCARE device.
Conclusion
In patients who underwent cardiac surgery, the mobiCARE device demonstrated diagnostic accuracy comparable to that of the conventional Holter monitoring system.
