What Is It to Be Mentally Healthy from the North Korean Refugees’ Perspective?: Qualitative Research on the Changes in Mental Health Awareness among the North Korean Refugees

OBJECTIVE: We investigated how mental health awareness among North Korean refugees transformed depending on temporal-spatial context changes. METHODS: In 2013, we conducted interviews with 10 refugees (eight women) who had been in South Korea for over a year and performed a qualitative analysis of the change in mental health awareness in the differences between living in North Korea, escape (a related period of forced sojourn in a third country), and settlement in South Korea. RESULTS: We classified 39 concepts into five main categories. The first two categories (while living in North Korea) were “a mindset for the system, but not for individual mental health” and “being confined in a social environment that was indifferent to mental health.” A third category appeared during escape: “focusing on survival amid continuity of intense suffering.” The final two categories appeared when settling in South Korea: “recognition of mental health amid cultural shock” and “introspection and sorting oneself out.” CONCLUSION: This qualitative study enabled a better multi-dimensional understanding of the social and cultural aspects involved in improving mental health awareness among North Korean refugees in South Korea. It is desirable to integrate mental health as a part of daily life and to expand training for North Korean settlers.

The Effects of Discrimination Experience on Life Satisfaction of North Korean Refugees: Mediating Effect of Stress

OBJECTIVE: This study investigated the mediation effect of stress between the experience of discrimination and life satisfaction among North Korean refugees who resettled in South Korea. The findings of the current study provide empirical evidence for the need of social interventions to mitigate adverse effects of stress on North Korean refugees who are subject to social discrimination on a daily basis. METHODS: In this study, we included 500 subjects among 2,138 North Korean refugees who took refuge in South Korea in 2007. The interview started from April 6th 2009 and finished on May 25th 2009. We conducted moderator effect analysis with Path analysis was conducted because we confirm the experience of discrimination was affected by life satisfaction and stress can affected life satisfaction as a moderator. RESULTS: The experience of discrimination significantly affects stress and stress significantly affects life satisfaction. However, the experience of discrimination was not directly related to life satisfaction. The more stress the study respondents experienced, the lower the life satisfaction they reported. CONCLUSION: The present finding suggests that the effects of discriminating experiences on the life satisfaction of North Korean refugees in South Korea were mediated by their own perceived stress.

Association between Sleep Duration and Injury from Falling among Older Adults: A Cross-Sectional Analysis of Korean Community Health Survey Data

PURPOSE: While sleeping problems increase with advancing age, there are inherent differences in sleep between males and females. Previous studies have shown inconsistent results of the relationship between sleep duration and risk of injury from falling. While controlling various sociodemographic and health-related factors, national representative data were used in order to analyze the association between sleep duration and injury from falling among older adults. MATERIALS AND METHODS: The data were obtained from the Korean Community Health Survey of 2011. A total of 55654 individuals aged 65 years and older participated in the study. Multivariable logistic regression analysis was conducted to identify the factors associated with injury from falling. RESULTS: After adjusting for covariates, such as age, sex, marital status, whether or not an individual is a recipient of benefits from the National Basic Livelihood Act, hypertension, diabetes mellitus, dyslipidemia, stress level, and self-rated health status, those who slept five hours or less per day [odds ratio (OR)=1.26; 95% confidence interval (CI)=1.18–1.34; p<0.001] or eight hours or more per day (OR=1.11; 95% CI=1.04–1.17; p=0.001) presented significantly higher ORs for injury from falling. A similar result was found when we conducted stratification by sex. CONCLUSION: The current study supports that there is a relationship between short sleep duration and injury from falling and also identified a marginal risk of long sleep in older adults. Therefore, sleep management in older adults with inadequate sleep duration may be necessary.

Gender Differences in Suicidal Ideation and Related Factors among North Korean Refugees in South Korea

OBJECTIVE: According to previous social survey, a high number of North Korean refugees (NKRs) in South Korea had suicidal ideation. The purpose of this study is to examine the related factors for suicidal ideation among NKRs by gender in South Korea. METHODS: We examined the sample of NKRs, 701 subjects (men=160, women=-541) residing in South Korea, the participants were enrolled from October 2008 to May 2014. The related factors with suicidal ideation in NKRs were analyzed via a logistic regression analysis. RESULTS: Refugee women were more likely to have suicidal ideation than men were. Although thoughts of suicide do not necessarily mean that they will follow through, however, there is an association that the higher rate of suicide also results in a higher rate of attempted suicide. In both genders, they tended to think more frequently about suicide who had stayed in South Korea for more than 5 years. In addition, higher frequencies of suicidal ideation also associated with higher level of perceived stress in both genders. CONCLUSION: The gender difference should be addressed when designing suicide prevention interventions among the North Korean population in South Korea.

Economic Evaluation of Diabetes Education / 임상당뇨병

BACKGROUND: Diabetes education, also known as diabetes self-management training or diabetes selfmanagement education, is effective in helping patients with diabetes control their illness and maximize their health. However, there is no established institutional strategy in South Korea because economic evaluations of the benefits and costs of diabetes education have been limited. The purpose of this study is two-fold: (1) describe economic evaluation methodologies, one of the tools available to help choose wisely from a range of alternatives and implement effective resources; and (2) suggest applications of economic evaluation in terms of diabetes education. METHODS: There are three types of commonly used economic evaluations in diabetes education: cost benefit analysis, cost effective analysis, and cost utility analysis. RESULTS: The understanding of the economic value of diabetes education for people with diabetes has a number of uses: to provide empirical evidence to influence policy-making in diabetes education, to offer proof of the benefits of diabetes self-management, to improve awareness of the importance and necessity of diabetes education, to reduce costs of diabetes management, and to enhance healthcare quality. CONCLUSION: Further research is needed to evaluate the economic benefits and costs associated with diabetes education.

A Study of Mental Health Literacy Among North Korean Refugees in South Korea / 예방의학회지

OBJECTIVES: This study aimed to investigate North Korean refugees' knowledge of mental illnesses and treatments and analyze the factors affecting this knowledge. METHODS: Subjects were selected via a snowball sampling method, and the survey outcomes of 152 North Korean refugee participants were analyzed. The factors affecting knowledge of mental illnesses were analyzed via a regression analysis by constructing a multivariate model with mental illness knowledge score as the dependent variable. RESULTS: The North Korean refugees' mental illness scores ranged from 3 to 24 points, with an average score of 13.0. Regarding the factors that influence mental illness knowledge, the subjects with South Korean spouses and those who had spent more time in South Korea had higher knowledge scores. Furthermore, the subjects who considered the mental health of North Korean refugees to be a serious issue revealed lower knowledge scores than those who did not believe it was a serious issue. The subjects who visit psychiatric clinics showed higher knowledge scores than those who do not. The South Korean subjects who had at least a college education exhibited higher scores than did those without advanced education. The subjects who are satisfied with life in South Korea manifested a higher mental illness knowledge score than those who are not. CONCLUSIONS: This study is significant as being the first study to ever measure and evaluate the level of North Korean refugees' knowledge of mental illnesses. In addition, the evaluations of North Korean refugees' mental illness knowledge and influencing factors while residing in South Korea created basic data that formed the foundation of an effort to enhance mental health literacy and provide proper mental health services. The results of this study can be utilized to solve mental health problems that might frequently occur during the unification process of North and South Korea in the future.

Diabetes Education Compliance and Knowledge among Diabetes Patients: Analysis of Patients Who Refuse Diabetes Education at an Academic Medical Center / 임상당뇨병

BACKGROUND: By determining the reasons why patients with diabetes did not take diabetes educationand by analyzingthe characteristics of these patients, this study aimed to provide baseline data to improvediabetes education participation rates. METHODS: A survey was conducted in 56 patients who had been hospitalized for diabetes treatment and who had refused to take the prescribed diabetes education. The reasons for refusing diabetes education and the level of diabetes knowledge were evaluated. Medical records were also reviewed to determine the subjects' hemoglobin A1c test results. RESULTS: The most common reason for rejecting diabetes education was 'previous experiencewith diabetes education.' The subjects also refused diabetes educations due to cost and an impression that they already have sufficient diabetes knowledge. The patients who refused the education due to expenses were among the lower income group, and 80 percent of patients who had received diabetes educationin the past declined the education because of their previous experience. CONCLUSION: In order to increase the participation rates of diabetes education, it is important that patients recognize the significance of ongoing diabetes education. Furthermore, to eliminate the cost problems, national efforts are required such as promoting National Health Insurance coverage to includediabetes education as well as expanding the patients' opportunities for receiving qualified diabetes education with systematic and standardized education materials for free.

Atypical Epidemiologic Finding in Association between Depression and Alcohol Use or Smoking in Korean Male: Korean Longitudinal Study of Aging

OBJECTIVE: The purpose of this study is to examine the relationship between substance use and depressive symptoms in a cohort of Koreans aged 45 years and older from a large, population-based study. Using the 2006 Korean Longitudinal Study of Aging, we estimated the prevalence of depressive symptoms and its association with smoking and alcohol use. METHODS: Depressive symptoms were measured using the CES-D 10-item scale. Age, marital status, educational attainment, employment and any disability were the control variables. Because there were gender differences in smoking and alcohol use, we also performed a separate analysis by gender. RESULTS: In the multivariable logistic regression, ex-drinkers were more likely to be depressed than non-drinkers (OR, 1.37; 95% CI, 1.08-1.74 for males; OR, 1.78; 95% CI, 1.23-2.57 for females). Compared to non-drinkers, males with moderate drinking habits (OR, 0.75; 95% CI, 0.63-0.90) were less likely to be depressed, whereas heavy male drinkers were more likely to be depressed (OR, 1.43; 95% CI, 1.07-1.91). Female smokers were more likely to be depressed than female non-smokers (OR, 2.07; 95% CI, 1.51-2.83). CONCLUSION: This study showed atypical pattern of relationship between smoking and depression and U-shaped relationship between depressive symptoms and alcohol consumption in male population. Both of these findings could be inferred from that these regional characteristics might be cross-sectional finding of chronologic transition result from a rapid rise of late life depression in Korea.

Information System Success Model for Customer Relationship Management System in Health Promotion Centers / 대한의료정보학회지

OBJECTIVES: Intensified competitiveness in the healthcare industry has increased the number of healthcare centers and propelled the introduction of customer relationship management (CRM) systems to meet diverse customer demands. This study aimed to develop the information system success model of the CRM system by investigating previously proposed indicators within the model. METHODS: The evaluation areas of the CRM system includes three areas: the system characteristics area (system quality, information quality, and service quality), the user area (perceived usefulness and user satisfaction), and the performance area (personal performance and organizational performance). Detailed evaluation criteria of the three areas were developed, and its validity was verified by a survey administered to CRM system users in 13 nationwide health promotion centers. The survey data were analyzed by the structural equation modeling method, and the results confirmed that the model is feasible. RESULTS: Information quality and service quality showed a statistically significant relationship with perceived usefulness and user satisfaction. Consequently, the perceived usefulness and user satisfaction had significant influence on individual performance as well as an indirect influence on organizational performance. CONCLUSIONS: This study extends the research area on information success from general information systems to CRM systems in health promotion centers applying a previous information success model. This lays a foundation for evaluating health promotion center systems and provides a useful guide for successful implementation of hospital CRM systems.

Factors influencing medical institution selection for outpatient services

This study analyzes determinants of patients' choice of healthcare providers in outpatient services and identifies their effects. Data were collected from two waves of the Korean Health Panel. The unit of analysis was an outpatient visit (n=189,739). Various types of medical institutions were grouped into general hospitals (including tertiary hospitals), hospitals, and clinics. A multinomial logit model was used to examine the determinants of medical institution selection. Clinics were the most frequent (82.2%) medical institution selected, followed by general hospitals (10.9%) and hospitals (6.9%). Males and beneficiaries of Medical Aid were more likely to choose the upper-level institutions. The upper-level institution selection was also positively associated with the level of education, household income, and severe diseases, while negatively associated with the level of health status. The medical institution selection was significantly different by region. Not only enabling factors for healthcare utilization, such as family and community resources, but also the users' characteristics were strong determinants of the type of medical institution selected. We, therefore, recommend that patients' characteristics and needs, in addition to the sharing of roles and functions among medical institutions, should be considered in making healthcare policies for efficient medical utilization and an effective medical delivery system.

Nationwide trends in stroke hospitalization over the past decade

Stroke is a major health problem in Korea. It is the second leading cause of death, and many stroke survivors are permanently disabled. Despite the high economic and social burden of stroke, little is known about utilization of health care services for sufficiently long follow-up periods. This study assessed nationwide patterns of hospitalization for inpatients with stroke from 2000 to 2010, using national health insurance claim data. Overall, during these 10 years, the number of stroke hospitalizations grew by a compound annual growth rate of 6.4%, and health care expenditures showed continued growth at a faster rate of 13.2%. These growth trends were also consistent in different types of hospitals as well as different stroke subtypes. However, the utilization patterns of inpatient services were different across hospital types, especially in lengths of hospital stay (LOS), health care expenditures, and proportions of stroke subtypes. Concerning the proportion of patients in different types of hospitals, there were sharp increases in the use of long-term care hospitals from 5% to 20% of all stroke patients while the proportion has decreased from 49% to 39% in general hospitals. The LOS was also different across hospital types: The longest average LOS of 49 days was shown in long-term care hospitals, while the tertiary hospitals showed the shortest LOS of 15. In conclusion, despite a continuing decline in stroke mortality due to improved survival, the burden of disease due to stroke is increasing. To manage this issue, monitoring the trends of health care expenditures in detail, as well as the incidence and mortality rates, would be useful. These efforts will result in understanding the factors contributing to the increasing burden and in identifying the efficient and effective utilization of limited health care resources.

Itemized Hospital Charges for Acute Cerebral Infarction Patients Influenced by Severity in an Academic Medical Center in Korea

BACKGROUND AND PURPOSE: Stroke imposes a major burden on patients, their families, and the national healthcare system. The purpose of this study was to determine the itemized hospital charges in acute ischemic stroke patients according to their severity by partitioning the charges in detail and then examining whether stroke severity was a significant contributor to these charges. METHODS: This study analyzed data of first-time acute ischemic stroke patients who had been admitted to an academic medical center between September 2003 and April 2009. The patients' demographic and clinical characteristics were analyzed descriptively, and then eight categorized hospital charges as well as the total charge were compared among patients grouped according to stroke severity, using analysis of variance. Multiple regression analyses were conducted to test the influence of stroke severity on itemized hospital charges as well as the total charge, while controlling for other related factors. RESULTS: More-severe strokes were associated with a higher total charge. Significantly higher charges were associated with patients with more-severe strokes regarding all charged items except imaging studies. The charges for imaging studies were similar across all severities of stroke. While controlling for other factors, a significant impact of stroke severity was found in both the total hospital charge and most itemized charges. CONCLUSIONS: Itemized hospital charges for inpatients with acute ischemic stroke varied according to stroke severity. Stroke severity was a significant factor influencing the itemized charges of acute hospitalization of ischemic stroke patients.

Impact of Health Insurance Type on Health Care Utilization in Patients with Acute Cerebral Infarction

BACKGROUND: Previous research has revealed that the type of health insurance significant impacts health-care utilization and patient health. The aim of this study was to describe and compare hospital service utilization and charges of inpatients with acute cerebral infarction among patients using two types of health insurance: National Health Insurance (NHI) and Medical Aid (MA). METHODS: The demographic, clinical, health-service utilization, and payment data of 1600 patients were analyzed. The patients were admitted within 7 days after the onset of stroke symptoms. Two insurance groups were compared in terms of patient characteristics and hospital charges using the chi-square test or the t-test. The significance of the impact of the health-insurance type on health-care utilization was tested after controlling for other related factors, using regression models. RESULTS: At the time of admission, the patients' gender, age, and stroke subtype differed significantly between the two insurance groups, whereas there were no differences in risk factors, admission route, referral status, or severity. There were no significant differences in treatments, length of stay, and referral status during their hospital stay. The total hospital charges and daily charges were significantly higher for patients with NHI than for patients with MA. In particular, significant differences were found in the categories of room and board, injection, laboratory tests, and imaging studies. CONCLUSIONS: There were significant differences between NHI and MA in terms of patient demographic characteristics, health-care utilization, and inpatient charges. Patients with NHI had higher hospital charges, especially in the categories of room and board and imaging tests.

The Determinants of the Use of Opportunistic Screening Programs in Korea / 예방의학회지

OBJECTIVES: Both organized and opportunistic screening programs have been widely used in Korea. This paper examined the determinants of the use of opportunistic screening programs in Korea. METHODS: The subjects were a national stratified random sample of 10,254 people aged 45 or older from the first wave of the Korean Longitudinal Study of Ageing in 2006. A logit model was used to examine the determinants of the use of opportunistic screening programs in terms of the demographic and socioeconomic characteristics, the type of health insurance and the health status. RESULTS: Thirteen point seven percent of the individuals received opportunistic screening programs within 2 years from the time the survey was conducted in 2006. The individuals who graduated from college or who had even more education were 3.0 times more likely to use opportunistic screening programs compared with the individuals who were illiterate. The individuals who resided in urban areas and who had religious beliefs were more likely to receive opportunistic screening programs compared with their counterparts. Those who were in the first quartile for the total household assets were 2.6 times more likely to use opportunistic screening programs than those who were in the fourth quartile for the total household assets. Privately insured people were 1.6 times more likely to use opportunistic screening programs than those who were not insured. Finally, the individuals who self-assessed their health status as worst were 2.1 times more likely to use opportunistic screening programs compared individuals who self-assessed their health status as best. CONCLUSIONS: This study suggests that opportunistic screening programs can be an indicator for whether or not an individual is among the advantaged group in terms of their socioeconomic characteristics and type of health insurance.

Determinants of Inpatient Charges of Acute Stroke Patients in Two Academic Hospitals: Comparison of Intracerebral Hemorrhage and Cerebral Infarction

BACKGROUND: Intracerebral hemorrhage (ICH) and cerebral infarction, which are two types of stroke, have different properties in terms of patient characteristics and hospital resource utilization. The two stroke types were evaluated in the present study with respect to the associated estimated inpatient charges, and their significant determinants. METHODS: The data of 497 stroke inpatients were collected from two academic hospitals in the year 2000~2001. The patients' demographic and clinical information were investigated retrospectively through medical records, and their payment data were extracted through the hospitals' information systems. The two types of stroke patient (i.e., ICH and cerebral infarction) were compared in terms of their demographic and clinical characteristics, and healthcare utilization. Multiple regression models were developed to examine the influence of demographic and clinical factors on inpatient charges. RESULTS: The mean length of hospital stay was 22.4 days for ICH patients and 18.3 days for those with cerebral infarction; the total inpatient charges were 5,777 and 3,908 thousand Korean won, respectively. While stroke severity, intensive care unit admission, surgery, and death were significant factors on inpatient charges for ICH patients (R2=0.426), additional factors such as diabetes, hospital, and department of care were significant for cerebral infarction patients (R2=0.342). CONCLUSIONS: The inpatient charges and their determinants differed between ICH and cerebral infarction. However, the length of hospital stay was found to be the most significant determinant of inpatient charges for both stroke types; stroke severity was also important with regard to the estimation of inpatient charges.

Use of Home Nursing Therapy and Need of Home Care Equipments
