Unmet healthcare is an important indicator to measure accessibility of healthcare services. To examine the latest status of unmet healthcare needs in South Korea, the four different data which is composed of nationally representative sample of South Korean population were used; the Korea Health and Nutrition Examination Survey (KNAHANES, 2007-2019), the Community Health Survey (CHS, 2008-2019), the Korea Health Panel Survey (KHP, 2011-2017), and the Korean Welfare Panel Study (KOWEPS, 2006-2019). The proportion of individuals reporting unmet healthcare needs were 5.8% (KNHANES), 5.3% (CHS), and 11.6% (KHP). Annual percentage change (APC) which identifies trend for the follow-up period was -9.5%, -8.0%, and -6.5%, respectively. The proportion of individuals reporting unmet healthcare needs due to cost were 1.1% (KNAHANES), 0.7% (CHS), 2.4% (KHP), and 0.4% (KOWEPS). The APC was -10.5%, -14.2%, -12.2%, and -19.6%, respectively. Compared to last year, the rate of unmet healthcare needs has declined in general. However, the low-income and the elderly population were reporting the highest rate of unmet health care needs, and the disparity between lowest and highest groups were remained. These results suggest that adequate benefit coverage is needed for low-income and elderly population.

Objectives: Recent studies have suggested that assessing handgrip strength (HGS) asymmetry together with HGS may be helpful for evaluating problems in geriatric patients. This study aimed to identify whether HGS asymmetry, weakness, or both were associated with depression in Korean older adults. Methods: This study included 4274 subjects from the sixth and seventh Korea National Health and Nutrition Examination Survey. Depression was measured using the Patient Health Questionnaire-9. The maximum HGS of the dominant hand was used as a representative value. HGS symmetry was categorized by the ratio of the HGS of the dominant hand to that of non-dominant hand. The odds ratio (OR) for depression was calculated according to the HGS and its symmetry. Results: In total, 240 (12.5%) men and 534 (22.7%) women had depression. HGS or HGS asymmetry showed no statistically significant associations with depression in elderly men. Elevated odds of depression were observed in elderly women with low HGS (OR, 1.93; 95% confidence interval [CI], 1.33 to 2.81) or prominent HGS asymmetry (OR, 1.46; 95% CI, 1.02 to 2.08). There was a positive additive interaction between asymmetric HGS and weakness, as women with low and prominently asymmetric HGS showed higher odds of depression (OR, 3.77; 95% CI, 2.16 to 6.59) than women with high and symmetric HGS. Conclusions: Depression in elderly Korean women was associated with both low and asymmetric HGS. Our findings support the potential value of HGS asymmetry as an indicator of HGS.

Unmet healthcare is an important indicator for measuring accessibility of healthcare services. We analyzed the following four data from a nationally representative sample of South Korean population: Korea Health and Nutrition Examination Survey (KNHANES, 2007-2021), Community Health Survey (CHS, 2008-2021), Korea Health Panel Survey (KHP, 2011-2019), and Korean Welfare Panel Study (KOWEPS, 2006-2021). The proportion of individuals reporting unmet healthcare needs were 6.0% (KNHANES), 5.1% (CHS), and 13.1% (KHP). Annual percentage change (APC) which identifies trend for the follow-up period was -9.4%, -9.4%, and -5.3%, respectively. The proportion of individuals reporting unmet healthcare needs due to cost were 1.2% (KNAHANES), 0.5% (CHS), 2.7% (KHP), and 0.4% (KOWEPS). The APC was -10.4%, -16.1%, -11.5%, and -19.1%, respectively. Compared to the previous year, the rate of unmet healthcare needs decreased slightly, but the rate of unmet health care needs due to cost tended to increase. Overall, higher rates of unmet healthcare needs were reported in the low-income and the elderly population. Although it was confirmed through the APC that the rate of unmet healthcare experience has decreased over the past decade, it can be seen that there is still a disparity by income level and age. These results suggest the need for an appropriate health benefit coverage policy for the low-income and the elderly.

이 연구의 목적은 사망수준의 저하에 영향을 미치는 세 요소-사회경제적 발전, 공공 보건의 발달, 사회경제적 발달의 균등상태-의 상대적 중요성을 분석하는 것이다. 종속변수인 사망 수준의 지표로는 영아사망률과 출생시 기대수명 등 두 변수가 사용되었다. 국민총생산(GNP)은 사회 경제적 발달지표로 여성의 초등학교 취학률과 기니계수(GINI index)는 사회경제적 균등상태 지표로 병원침대당 인구수는 공공보건 지표로 간주되었다. 변수들에 대한 자료는 두 시점에 걸쳐 수집되었다. 하나는 1970년 이전 53개국에서. 다른 하나는 1970-80년대 55개국에서 수집되었다. 탐색적 자료 분석 방법이 통계 분석 방법으로 사용되었다. 이 기법은 종속변수와 독립변수와의 관계가 선형인지 아닌지, 그리고 우리 모형에서 어느 것이 유력 사례인지를 파악할 수 있는 장점이 있다. 분석결과에 따르면, 첫째로 영아 사망률과 세 요소의 관계가 선형이 아니라 비선형임이 밝혀졌다. 영아 사망률 저하에 국민총생산이 가장 많이, 여성의 초등학교 취학률이 두 번째, 기니계수가 그 다음으로 영향을 미치는 것으로 나타났다. 반면 병원침대당 인구수는 통계적으로 유의미한 영향을 보여주지 않았다. 둘째, 출생시 기대수명은 여성의 취학률, 기니계수 등과 같은 변수와는 선형 관계를 가지는 반면 국민총생산 변수와는 비선형 관계를 가진다. 영아사망률 변수와는 달리 출생시 기대수명의 변이에는 여성의 초등학교 취학률이 국민총생산보다 더 커다란 영향을 미쳤다.

Purpose: The purpose of this study is to analyze the intervention studies for married immigrant women. Methods: Based on inclusion criteria, 45 articles published from 2006 to 2011 were reviewed and analyzed. Results: Among the total amount of studies, 77.8% have been conducted since 2009; and 46.7% of them were for a master's thesis, 11.1% were for a doctoral thesis, and 42.2% were journal articles. Most of them were quantitative research (77.8%) and 71.1% were conducted in urban areas. The most frequently conducted intervention was art therapy (35.6%), whereas 6.7% was health education. In total, 104 outcome indicators were used with 57 (54.8%) in the mental health domain, 29 (27.9%) in the social health domain, and 18 (17.3%) in the physical health domain. The most commonly used outcome indicator was self-esteem (23.2%), and the next, in the order of frequency, included self-efficacy (23.2%), acculturative stress (21.4%), and depression (10.7%). Conclusion: Most intervention studies were conducted to support the sociocultural adaptation of married immigrant women, while few intervention studies were conducted to support the health of married immigrant women. To promote the health and quality of life of married immigrant women, many health related intervention programs should be undertaken.

Liver enzyme elevations, as an indicator of liver function, are widely associated with metabolic diseases. Genome-wide population-based association studies have identified a genetic susceptibility to liver enzyme elevations and their related traits; however, the genetic architecture in childhood remains largely unknown. We performed a genome-wide association study to identify new genetic loci for liver enzyme levels in a Korean childhood cohort (n = 484). We observed three novel loci (rs4949718, rs80311637, and rs596406) that were multiply associated with elevated levels of alanine transaminase and aspartate transaminase. Although there are some limitations, including genetic power, additional replication and functional characterization will support the clarity on the genetic contribution that the ST6GALNAC3, ADAMTS9, and CELF2 genes have in childhood liver function.

Background: Increasing evidence from animal, epidemiological and clinical investigations suggest that dietary anthocyanins have potential to prevent chronic diseases, including cancers. It is also noteworthy that human epidermal growth factor receptor 2 (ErbB2) protein overexpression or ErbB2 gene amplification has been included as an indicator for metastasis and higher risk of recurrence for breast cancer. Materials and Methods: The present experiments investigated the anti-metastasis effects of black rice anthocyanins (BRACs) on ErbB2 positive breast cancer cells in vivo and in vitro. Results: Oral administration of BRACs (150 mg/kg/day) reduced transplanted tumor growth, inhibited pulmonary metastasis, and decreased lung tumor nodules in BALB/c nude mice bearing ErbB2 positive breast cancer cell MDA-MB-453 xenografts. The capacity for migration, adhesion, motility and invasion was also inhibited by BRACs in MDA-MB-453 cells in a concentration dependent manner, accompanied by decreased activity of a transfer promoting factor, urokinase-type plasminogen activator (u-PA). Conclusions: Together, our results indicated that BRACs possess anti-metastasis potential against ErbB2 positive human breast cancer cells in vivo and in vitro through inhibition of metastasis promoting molecules.

Purpose: The aims of this study were to assess the presence of core patient safety practices in Korean hospitals and assess the differences in reporting and learning systems of patient safety, infrastructure, and safe practices by hospital characteristics. Methods: The authors developed a questionnaire including 39 items of patient safety staffing, health information system, reporting system, and event-specific prevention practices. The survey was conducted online or e-mail with 407 tertiary, general and specialty hospitals. Results: About 90% of hospitals answered the self-reporting system of patient safety related events is established. More than 90% of hospitals applied incidence monitoring or root cause analysis on healthcare-associated infection, in-facility pressure ulcers and falls, but only 60% did on surgery/procedure related events. More than 50% of the hospitals did not adopted present on admission (POA) indicators. One hundred (80.0%) hospitals had a department of patient safety and/or quality and only 52.8% of hospitals had a patient safety officer (PSO). While 82.4% of hospitals used electronic medical records (EMRs), only 53% of these hospitals adopted clinical decision support function. Infrastructure for patient safety except EMRs was well established in training, high-level and large hospitals. Most hospitals implemented prevention practices of adverse drug events, in-facility pressure ulcers and falls (94.4-100.0%). But prevention practices of surgery/procedure related events had relatively low adoption rate (59.2-92.8%). Majority of prevention practices for patient safety events were also implemented with a relatively modest increase in resources allocated. Conclusion: The hospital-based reporting and learning system, EMRs, and core evidence-based prevention practices were implemented well in high-level and large hospitals. But POA indicator and PSO were not adopted in more than half of surveyed hospitals and implementation of prevention practices for specific event had low. To support and monitor progress in hospital's patient safety effort, national-level safety practices set is needed.

Background: The purpose of this study was to propose a method for developing a measure of hospital-wide all-cause risk-standardized readmissions using administrative claims data in Korea and to discuss further considerations in the refinement and implementation of the readmission measure. Methods: By adapting the methodology of the United States Center for Medicare & Medicaid Services for creating a 30-day readmission measure, we developed a 6-step approach for generating a comparable measure using Korean datasets. Using the 2010 Korean National Health Insurance (NHI) claims data as the development dataset, hierarchical regression models were fitted to calculate a hospital-wide all-cause risk-standardized readmission measure. Six regression models were fitted to calculate the readmission rates of six clinical condition groups, respectively and a single, weighted, overall readmission rate was calculated from the readmission rates of these subgroups. Lastly, the case mix differences among hospitals were risk-adjusted using patient-level comorbidity variables. The model was validated using the 2009 NHI claims data as the validation dataset. Results: The unadjusted, hospital-wide all-cause readmission rate was 13.37%, and the adjusted risk-standardized rate was 10.90%, varying by hospital type. The highest risk-standardized readmission rate was in hospitals (11.43%), followed by general hospitals (9.40%) and tertiary hospitals (7.04%). Conclusion: The newly developed, hospital-wide all-cause readmission measure can be used in quality and performance evaluations of hospitals in Korea. Needed are further methodological refinements of the readmission measures and also strategies to implement the measure as a hospital performance indicator.
