Analyzing the Effectiveness of Data-Linked Projects for Health Promotion in Public Health Centers of South Korea.

Purpose: The purpose of this study lies in verifying the effectiveness of the health promotion project which the public health center at the local level conducted by systematically linking the health examination results from the Health Insurance Corporation. We intend to emphasize the importance of linking the health-related public data. Methods: A survey was conducted to measure the effect of improving health behavior using EQ-5D-5L and demographic variables. Results: As a result of the analysis, the residents (3.13) who had experienced the use of public health centers recognized more necessity for the service linked systematically with health checkup data than those (2.93) who had not. In addition, the residents who had experienced the use of public health centers responded that their chronic diseases had improved compared to a year ago (2.78→2.93). Next, those (3.04) who had experienced the services linked with health checkup data recognized that their chronic diseases and health conditions had been improved compared to those (2.81) who had not. However, in EQ-5D-5L, after using the service, mobility showed no difference between those who had used the service and those who had not. Furthermore, even in terms of self-management, daily life, etc., the management ability was further improved compared to those who had not used it, before using the service. Conclusion: This study showed the improved health level when the health promotion service of the public health center was provided by systematically linking the health checkup data of the Health Insurance Corporation in Korea. In order to increase the effectiveness of health data-linked projects, it is necessary to prepare guidelines for linking the public health data and to expand the data-linked project. It will be needed to further subdivide the health checkup results to provide customized services, and to secure dedicated personnel to reinforce the system link.

Strategic management and organizational culture of medical device companies in relation to corporate performance.

AIMS: Strategies focus on securing the competitiveness of medical device corporations by strengthening their organizational capabilities, which, in turn, ensure their continuous development. This study aims to investigate both management strategies and organizational culture, which may affect the performance of these companies, and analyzes the influence of education and training investment. MATERIALS AND METHODS: We used data from the 3rd to 6th Human Capital Corporate Panel surveys by the Korea Research Institute for Vocational Education and Training as well as data from the Korea Information Service and 6,112 workers and 260 companies were analyzed. For the analysis, management strategy and organizational culture were set as independent variables, and corporation performance was set as the dependent variable. Additionally, investment in education and training was set as a control variable between the independent and dependent variables. Corporate performance was analyzed by dividing into organizational satisfaction and organizational commitment. RESULTS: Differentiation strategy and innovative culture had a positive (+) effect on organizational satisfaction, while cost leadership strategy and hierarchical culture had a negative (-) effect. On the other hand, in the case of interaction with education and training investment, cost leadership strategy and hierarchical culture had a positive (+) effect, while differentiation strategy and innovation culture had a negative (-) effect. In organizational commitment, innovation culture had a positive (+) effect, and hierarchical culture had a negative (-) effect. In the case of interaction with investment in education and training, only the hierarchical culture had a positive (+) effect. CONCLUSIONS: The innovation culture positively influenced the performance of medical device companies. Furthermore, cost leadership strategy, hierarchical culture, education and training investment improved the corporate performance of these companies. To enhance corporate performance, these companies should create an innovation culture and invest in education and training in accordance with the organizational culture.

COVID-19 has proven the excellence of Korea's medical devices, and the medical device industry is expected to continue to grow due to the increase in chronic disease and non-face-to-face treatment. However, the current medical device industry is monopolized by global companies with capital and technological prowess. To overcome this, Korean medical device companies are developing innovative medical devices centered on start-ups, but now is the time to strategically respond to them in order to compete with global companies. In general, companies establish management strategies for survival and growth by analyzing threats and opportunities based on the market environment to maintain the optimal organization according to market competition, government policies, and changes in consumer needs. Strategies are often established based on the culture of the organizations that make up the company. When it comes to strategy establishment, the medical device industry has special characteristics compared to other industries. The medical device industry is based on advanced technology and puts patient safety first, requiring continuous product upgrades. Therefore, it is an essential industry for employees to invest in education and training. The analysis shows the effectiveness of investment in education and training according to the management strategy and organizational culture of medical device companies. It was confirmed that when medical device companies create an Innovation culture, their performance improves. It also shows that when medical device companies adopt a cost leadership strategy, they need to increase their investment in education and training to improve corporate performance.

Spinal Cord Injury Fact Sheet in Korea.

Spinal cord injury (SCI) has been recognized as a medically complex and life-disrupting condition. As the aging of the population accelerates, the trend of SCI has changed. This review aimed to provide comprehensive statistics and recent epidemiological changes in SCI and rehabilitation in Korea. All three insurance databases (National Health Insurance Service [NHIS], automobile insurance [AUI], and industrial accident compensation insurance [IACI]) were considered. These nationwide databases provide data on the current trends in term of incidence, etiology, and rehabilitation of SCI. Traumatic spinal cord injury (TSCI) was more frequent among the elderly in the NHIS compared to working age individuals in the AUI and IACI. In all three trauma-related insurance databases, male with TSCI outnumbered female. TSCI incidence per year was approximately 17 times higher among males than females, on average, in IACI. In all three insurances, the cervical level of TSCI was the most frequent. Although the ratio of SCI patients receiving rehabilitation treatment at primary and secondary hospitals increased for nine years, the increase in training on activities of daily living (ADL training) was found to be relatively small. This review provides a broader and comprehensive understanding of the incidence, etiology, and rehabilitation treatment of SCI in Korea.

Comparison of Trends in the Incidence of Traumatic Spinal Cord Injury in Daily Life, Automobile Accidents, and Industrial Accidents: A National Multi-Insurance Study in Korea.

BACKGROUND: To examine the incidence of traumatic spinal cord injury (TSCI) from all etiologies, we measured and compared the incidence of TSCI from three national or quasi-national databases in South Korea, namely, the National Health Insurance Service (NHIS), automobile insurance (AUI), and Industrial Accident Compensation Insurance (IACI). METHODS: We reviewed patients with TSCI reported in the NHIS database between 2009 and 2018, and in the AUI and IACI databases between 2014 and 2018. TSCI patients were defined as those first admitted to the hospital with a diagnosis of TSCI according to the International Classification of Diseases (10th revision) criteria. Age-adjusted incidence was calculated using direct standardization using the 2005 South Korean population or the 2000 US population as the standard population. The annual percentage changes (APC) of TSCI incidence were calculated. The Cochrane-Armitage trend test was performed according to the injured body region. RESULTS: In the NHIS database, age-adjusted TSCI incidence using the Korean standard population increased significantly from 2009 to 2018 (from 33.73 per million in 2009 to 38.14 per million in 2018, APC = 1.2%, P = 0.014). Contrarily, age-adjusted incidence in the AUI database significantly decreased from 13.88 per million in 2014 to 11.57 per million in 2018 (APC = - 5.1%, P = 0.009). In the IACI database, the age-adjusted incidence showed no significant difference, while crude incidence showed a significant increase (from 22.02 per million in 2014 to 28.92 per million in 2018, APC = 6.1%, P = 0.038). According to the age group, all the three databases showed high incidences of TSCI in those in their 60s and 70s or older. Among those in their 70s or older, the incidence of TSCI increased dramatically in the NHIS and IACI databases, while no significant trend was found in AUI database. In 2018, the number of TSCI patients was the highest among those over 70 years of age in the NHIS, whereas among those in their 50s were the highest in both AUI and IACI. The proportion of patients with cervical spinal cord injury was the most common in all these databases. CONCLUSIONS: The differences in trends in the incidence of TSCI may be due to the different etiologies and different characteristics of subjects depending on insurance type. These results imply the need for tailored medical strategies for the different injury mechanisms represented by three national insurance services in South Korea.

An analytic hierarchy process analysis for reinforcing doctor-patient communication.

BACKGROUND: As the health paradigm shifts toward patient-centeredness, patients can actively participate in their own treatment. However, there is still a unilateral aspect of doctor-patient communication, so it is necessary to specify obstacles between doctors and patients. Therefore, this study attempted to extract obstacles that block doctor-patient communication and to analyze differences in perception of doctor-patient communication. METHODS: A total of 35 questionnaires composed of brainstorming for the study were distributed, and a total of 21 questionnaires were used for analysis. The collected data was analyzed by AHP using dress ver 17.0. RESULTS: As a result of the study, doctors ranked the priority of health communication in the order of professionalism, reliability, fairness, communication, and psychologically. On the other hand, for patients, the priority factors of health communication were communication, fairness, professionalism, reliability, and psychologically. CONCLUSION: In order to improve the quality of health communication between doctors and patients, doctors will be able to communicate from the patient's point of view and strengthen communication with patients by providing consistent medical services and patients need to trust the doctor and patients need to trust their doctors and participate in the medical process faithfully.

Incidence of Depression after Traumatic Brain Injury: A Nationwide Longitudinal Study of 2.2 Million Adults.

Although improvements in acute care for traumatic brain injury (TBI) have increased the patient survival rate, many survivors often suffer from neuropsychiatric sequelae such as depression. This study investigated the influence of TBI on the risk of depression using South Korean nationwide data. Data were extracted from the National Health Insurance Service database for patients who experienced TBI from 2010 to 2017 (n = 1,141,593) and for 1:1 matched controls without TBI (n = 1,141,593). Patients under 18 years old or with a history of depression were excluded. TBI was used as a time-varying exposure and a time-dependent Cox regression model was adopted. Age, sex, insurance premium and type, region of residence, past psychiatric diseases, and Charlson Comorbidity Index were adjusted. The incidence of depression in the patients with TBI and matched controls was 34.60 and 21.42 per 1000 person-years, respectively. The risk of depression was higher in the patients with TBI (hazard ratio [HR] 1.19, 95% confidence interval [CI] = 1.18-1.20) than in the matched control group. After stratification by sex and age, the risk was higher in men and the younger age group. In subgroup analyses, patients with skull fracture showed the highest risk of depression. Notably, during the first year after TBI, the depression risk was almost 11 times higher than that in the matched control group (HR 11.71, 95% CI = 11.54-11.87). Our findings highlight a significant association of TBI with an increased risk of subsequent depression. Therefore, continuous awareness with regard to patients' mental health is needed.

Factors associated with assisted ventilation use in amyotrophic lateral sclerosis: a nationwide population-based study in Korea.

Few studies have investigated the factors associated with assisted ventilation use in amyotrophic lateral sclerosis (ALS) in western countries with a relatively small number of participants. This study aimed to evaluate the factors associated with assisted ventilation use using a large nationwide cohort covering the entire Korean population. We selected patients with primary or secondary diagnoses of ALS (ICD-10 code: G12.21) and a registration code for ALS (V123) in the rare intractable disease registration program. Covariates included in the analyses were age, sex, socioeconomic status and medical condition. Factors associated with non-invasive ventilation (NIV) and tracheostomy invasive ventilation (TIV) were evaluated. Logistic regression analyses were performed using odds ratios and 95% confidence intervals. In total, 3057 patients with ALS were enrolled. During the 6-year follow-up period, 1228 (40%) patients started using assisted ventilation: 956 with NIV and 272 with TIV. There was no significant difference in the assisted ventilation use according to sex, whereas different patterns of discrepancies were noted between the sexes: Females living in non-metropolitan areas showed decreased use of assisted ventilation, whereas high income levels showed a positive relationship with assisted ventilation use only in males. Patients aged ≥ 70 years showed decreased use of NIV. NIV use was more affected by socioeconomic status than TIV, whereas TIV showed a significant relationship with medical conditions such as nasogastric tube insertion and gastrostomy. We found that various factors, including age, socioeconomic status, and medical condition, were related with assisted ventilation use. Understanding the pattern of assisted ventilation use would help set optimal management strategies in patients with ALS.

Factors affecting revisit intention for medical services at dental clinics.

Recent changes in the medical paradigm highlight the importance of patient-centered communication. However, because of the lack of awareness of dental clinics and competency of medical personnel, the quality of medical services in terms of the communication between doctors and patients has not improved. This study analyzed the impact of health communication and medical service quality, service value, and patient satisfaction on the intention to revisit dental clinics. The study participants were outpatients treated at 10 dental clinics in Seoul. The research data were collected using a questionnaire during visits to these dental clinics from December 1 to December 30, 2016. A total of 600 questionnaires were distributed (60 copies to each clinics) and 570 valid questionnaires were used for the analysis. The influence of the factors was determined using structural equation modeling. The factors influencing service value were reliability (ß = 0.364, p < 0.001), expertise (ß = 0.319, p < 0.001), communication by doctors (ß = 0.224, p < 0.001), and tangibility (ß = 0.136, p < 0.05). In addition, the factors influencing patient satisfaction were reliability (ß = 0.258, p < 0.001), tangibility (ß = 0.192, p < 0.001), communication by doctors (ß = 0.163, p < 0.001), and expertise (ß = 0.122, p < 0.01). Further, service value (ß = 0.438, p < 0.001) raised patient satisfaction, which was found to influence the intention to revisit dental clinics (ß = 0.383, p < 0.001). Providing accurate medical services to inpatients based on smooth communication between doctors and patients improves patient satisfaction. In addition, doctors can build long-term relations with patients by increasing patients' intention to revisit through patient-oriented communication.

The Effect of Changes in Employment on Health of Work-Related Injured Workers: A Longitudinal Perspectives.

This longitudinal study attempted to identify changes in employment status and overall health status. The participants were workers who had experienced work-related injuries in the past. In this study, we used the Panel Study of Workers' Compensation Insurance from 2013 to 2017. This study utilized propensity score matching for a quasi-experimental design study of the first year to exclude the effects of the confounding variables and exclude the effect of employment status, which is the main independent variable. After applying propensity score matching the research subjects totaled 1070. Changes in employment status were found to have a negative effect on overall health status. This raises new implications for existing industrial accident-related support policies. Thus, it is considered that the scope should be expanded from policies related to re-employment of workers after an industrial accident to improving quality of life through maintaining employment from a long-term perspective. The notable point of this study was to apply the PSM methods. By applying PSM, we clearly identified the effect of changes in employment status on health status.

Epidemiological Trends and Rehabilitation Utilization of Traumatic Brain Injury in Korea (2008-2018).

This study aimed to estimate the trend of traumatic brain injuries (TBIs) and TBI-related medical usage in Korea. Patients first diagnosed with disease codes of TBIs were included. We calculated the crude incidence and age-adjusted incidence, as well as medical cost, length of stay (LOS), clinic visits, and the number of specialized rehabilitation therapy for 1 year. Patients first diagnosed as TBI was higher in national health insurance (NH-I) than in automobile insurance (AUTO-I). In contrast with the gradual decrease of the crude incidence, total medical costs both in NH-I and AUTO-I were generally and steadily increased. For oriental medicine, total medical costs dramatically increased in both inpatient and outpatient. LOS, clinic visits, and the number of specialized rehabilitation therapy were higher in AUTO-I than in NH-I. The most frequent age groups in NH-I were the young (0-9) and old (70 or over), whereas in AUTO-I, the working age group was prominent. Our results show differences in the incidence of TBI and medical usage between NH-I and AUTO-I, which could be associated with the policy for strengthening health insurance coverage, automobile-related regulations to prevent accidents and injuries, as well as rapid changes in the structure of the population in Korea.

The Socioeconomic Burden of Acquired Brain Injury among the Korean Patients over 20 Years of Age in 2015-2017: a Prevalence-Based Approach.

Acquired brain injury (ABI) is a leading cause of serious long-term disability resulting in substantial economic costs for post-ABI care. This study was conducted to estimate the socioeconomic burden of persons with ABI in Korea. We used a prevalence-based approach and societal perspective to estimate the direct medical, non-medical costs and indirect costs of ABI, including stroke, traumatic brain injury (TBI), and non-traumatic ABI (anoxia, brain tumor, encephalitis, meningitis, hydrocephalus, and other brain disorders) from 2015 to 2017. The study population included patients with ABI over 20 years of age and analyzed according to insurance types encompassing National Health Insurance and automobile insurance. The socioeconomic burden of ABI was 4.67, 5.18, and 5.73 trillion KRW (approximately 4,162, 4,612, and 5,106 million USD) from 2015 to 2017 and around 0.3% of Korea's GDP annually. Estimating by disease, the socioeconomic cost was 72.4% for stroke, 18.6% for TBI, and 9.0% for non-traumatic ABI. Calculated by cost component, medical costs and non-medical costs showed a slight increase every year. Through this study, establishment of rehabilitation systems maximizing the health and quality of life for injured persons remain the key public health strategy for ABI to reduce socioeconomic burden and financial policies to support patients should be needed.

Decreasing Incidence and Mortality in Traumatic Brain Injury in Korea, 2008-2017: A Population-Based Longitudinal Study.

Traumatic brain injury (TBI), a global public health concern, may lead to death and major disability. While various short-term, small-sample, and cross-sectional studies on TBI have been conducted in South Korea, there is a lack of clarity on the nationwide longitudinal TBI trends in the country. This retrospective study investigated the epidemiological TBI trends in South Korea, using a population-based dataset of the National Health Insurance (2008-2017). The crude and age adjusted TBI incidence and mortality values were calculated and stratified by age, sex, and TBI diagnosis. The age-adjusted incidence per 100,000 people increased until 2010 and showed a decreasing trend (475.8 cases in 2017) thereafter; however, a continuously decreasing age-adjusted mortality trend was observed (42.9 cases in 2008, 11.3 in 2017). The crude incidence rate increased continually in those aged >70 years across all the TBI diagnostic categories. The mortality per 100,000 people was significantly higher among participants aged ≥70 years than in the other age groups. We observed changing trends in the TBI incidence, with a continuously decreasing overall incidence and a rapidly increasing incidence and high mortality values in older adults. Our findings highlight the importance of active TBI prevention in elderly people.

Factors associated with health services utilization between the years 2010 and 2012 in Korea: using Andersen's Behavioral model.

OBJECTIVES: This study aimed to examine the factors associated with health services utilization using Andersen's behavioral model. METHODS: We collected Korea Health Panel data between the years 2010 and 2012 from the consortium of the National Health Insurance Service and the Korea Institute for Health and Social Affairs, and analyzed the data to determine the outpatients and inpatients of health services utilization. RESULTS: Health services utilization was more significantly explained by predisposing and need factors than enabling factors. The outpatients were examined more specifically; sex, age, and marital status as predisposing factors, and chronic illness as a need factor were the variables that had significant effects on health-services-utilization experience. The inpatients were examined more specifically: sex, age, and marital status in predisposing factors; education level, economic activities, and insurance type in enabling factors; and chronic illness and disability status in need factors were the significant variables having greater effects on health-services-utilization experience. CONCLUSION: This study suggests the practical implications for providing health services for outpatients and inpatients. Moreover, verifying the general characteristics of outpatients and inpatients by focusing on their health services utilization provides the baseline data for establishing health service policies and programs with regard to the recently increasing interest in health services.

Association between shift work and severity of depressive symptoms among female nurses: the Korea Nurses' Health Study.

AIM: To determine the prevalence of depression and the relationship between shift work and depression severity among female nurses in South Korea. BACKGROUND: Shift work has been associated with higher risks of depressive symptoms, but there is a dearth of research on nurses, particularly investigating the severity of depressive symptoms. METHODS: Quantitative data including survey response from 9789 participants were analysed. Statistical analysis included descriptive, Spearman's correlation and multivariable ordinal logistic regression. RESULTS: The numbers of nurses according to the severity of depressive symptoms were 35.2% (n = 3445), 38.0% (n = 3716), 16.1% (n = 1578), 7.6% (n = 747) and 3.1% (n = 303) for normal, mild, moderate, severely moderate and severe level of depressive symptoms, respectively. After adjusting for sociodemographic and health behavioural factors, nurses who worked shifts had 1.519-times greater odds of experiencing a higher severity of depressive symptoms (OR = 1.519, CI = 1.380-1.674, P < 0.001). CONCLUSION: This study shows a higher prevalence of depressive symptoms among nurses who worked shifts and suggests that shift work may increase the severity of depressive symptoms among female nurses in South Korea. IMPLICATIONS FOR NURSING MANAGEMENT: Nursing professionals, managers and health policy makers need to understand the factors influencing depressive symptoms and to use appropriate interventions based on the severity and not just the onset.
