Cost-utility analysis of transitional care services for older inpatients with chronic obstructive pulmonary disease (COPD) in Korea.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is associated with a high readmission rate and poses a significant disease burden. South Korea initiated pilot projects on transitional care services (TCS) to reduce readmissions. However, evidence from cost-effectiveness analyses remains undiscovered. This study aimed to evaluate the cost-effectiveness of TCS in patients with COPD from the healthcare system' perspective. METHOD: A cost-utility analysis was conducted using a Markov model containing six components of possible medical use after discharge. Transition probabilities and medical costs were extracted from the National Health Insurance Service Senior Cohort (NHIS-SC), and utility data were obtained from published literature. Sensitivity analyses were performed to test the robustness of the results. RESULTS: Conducting TCS produced an incremental quality-adjusted life years gain of 0.231, 0.275, 0.296 for those in their 60s, 70s, and 80s, respectively, and cost savings of $225.16, $1668, and $2251.64 for those in their 60s, 70s, and 80s, respectively, per patient over a 10-year time horizon. The deterministic sensitivity analysis indicated that the TCS cost and the cost of readmission by other diseases immensely impact the results. The probabilistic sensitivity analyses showed that the probability that the incremental cost-effectiveness ratio is below $23,050 was over 85%, 93%, and 97% for those in the 60s, 70s, and 80s, respectively. CONCLUSIONS: TCS was the dominant option compared to usual care. However, it is advantageous to the healthcare budget preferentially consider patients aged over 70 years with severe TCS symptoms. In addition, it is essential to include the management of underlying comorbidities in TCS intervention. TRIAL REGISTRATION: Clinical Research Information Service (CRIS), KCT0007937.

Facilitating and barrier factors to the implementation of a transitional care program: a qualitative study of hospital coordinators in South Korea.

BACKGROUND: Transitional care is an integrated service to ensure coordination and continuity of patients' healthcare. Many models are being developed and implemented for this care. This study aims to identify the facilitators and obstacles of project performance through the experiences of the coordinator in charge of the Community Linkage Program for Discharge Patients (CLDP), a representative transitional care program in Korea. METHOD: Forty-one coordinators (nurses and social workers) from 21 hospitals were interviewed using a semi-structured questionnaire, and thematic analysis was performed. RESULT: Three themes were found as factors that facilitate or hinder CLDP: Formation and maintenance of cooperative relationships; Communication and information sharing system for patient care; and interaction among program, regional, and individual capabilities. These themes were similar regardless of the size of the hospitals. CONCLUSION: A well-implemented transitional care model requires a program to prevent duplication and form a cooperative relationship, common computing platform to share patient information between institutions, and institutional assistance to set long-term directions focused on patient needs and support coordinators' capabilities.

Risks for Readmission Among Older Patients With Chronic Obstructive Pulmonary Disease: An Analysis Using Korean National Health Insurance Service - Senior Cohort Data.

OBJECTIVES: The high readmission rate of patients with chronic obstructive pulmonary disease (COPD) has led to the worldwide establishment of proactive measures for identifying and mitigating readmissions. This study aimed to identify factors associated with readmission, as well as groups particularly vulnerable to readmission that require transitional care services. METHODS: To apply transitional care services that are compatible with Korea's circumstances, targeted groups that are particularly vulnerable to readmission should be identified. Therefore, using the National Health Insurance Service's Senior Cohort database, we analyzed data from 4874 patients who were first hospitalized with COPD from 2009 to 2019 to define and analyze readmissions within 30 days after discharge. Logistic regression analysis was performed to determine factors correlated with readmission within 30 days. RESULTS: The likelihood of readmission was associated with older age (for individuals in their 80s vs. those in their 50s: odds ratio [OR], 1.59; 95% confidence interval [CI], 1.19 to 2.12), medical insurance type (for workplace subscribers vs. local subscribers: OR, 0.84; 95% CI, 0.72 to 0.99), type of hospital (those with 300 beds or more vs. fewer beds: OR, 0.77; 95% CI, 0.66 to 0.90), and healthcare organization location (provincial areas vs. the capital area: OR, 1.66; 95% CI, 1.14 to 2.41). CONCLUSIONS: Older patients, patients holding a local subscriber insurance qualification, individuals admitted to hospitals with fewer than 300 beds, and those admitted to provincial hospitals are suggested to be higher-priority for transitional care services.

Korea Seroprevalence Study of Monitoring of SARS-COV-2 Antibody Retention and Transmission (K-SEROSMART): findings from national representative sample.

OBJECTIVES: We estimated the population prevalence of antibodies to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), including unreported infections, through a Korea Seroprevalence Study of Monitoring of SARS-CoV-2 Antibody Retention and Transmission (K-SEROSMART) in 258 communities throughout Korea. METHODS: In August 2022, a survey was conducted among 10,000 household members aged 5 years and older, in households selected through two stage probability random sampling. During face-to-face household interviews, participants self-reported their health status, COVID-19 diagnosis and vaccination history, and general characteristics. Subsequently, participants visited a community health center or medical clinic for blood sampling. Blood samples were analyzed for the presence of antibodies to spike proteins (anti-S) and antibodies to nucleocapsid proteins (anti-N) SARS-CoV-2 proteins using an electrochemiluminescence immunoassay. To estimate the population prevalence, the PROC SURVEYMEANS statistical procedure was employed, with weighting to reflect demographic data from July 2022. RESULTS: In total, 9,945 individuals from 5,041 households were surveyed across 258 communities, representing all basic local governments in Korea. The overall population-adjusted prevalence rates of anti-S and anti-N were 97.6% and 57.1%, respectively. Since the Korea Disease Control and Prevention Agency has reported a cumulative incidence of confirmed cases of 37.8% through July 31, 2022, the proportion of unreported infections among all COVID-19 infection was suggested to be 33.9%. CONCLUSIONS: The K-SEROSMART represents the first nationwide, community-based seroepidemiologic survey of COVID-19, confirming that most individuals possess antibodies to SARS-CoV-2 and that a significant number of unreported cases existed. Furthermore, this study lays the foundation for a surveillance system to continuously monitor transmission at the community level and the response to COVID-19.

Development of Items for Transitional Care Service and Outcome Indicators of Discharged Patients for Improvement in Quality of Care.

BACKGROUND: In this study, with the aim of improving the quality of transitional care service for discharged patients, the Health Care Quality and Outcomes Indicators of the Organization for Economic Co-operation and Development and National Health Service Outcomes Framework of the UK were applied to derive service items for provision and develop evaluation indicators under categories of effectiveness, safety, and patient-centeredness. METHOD: A scoping review was conducted to derive core concepts and evidence materials/data for transitional care service. For the derived items of transitional care service and evaluation indicators, a three-round Delphi study was conducted with experts in the fields of healthcare/medicine/nursing/social welfare. RESULTS: First, as a result of the scoping review, components of transitional care service (assessment of need by period of transitional care service, multi-professional team, connection to community resources, etc.) and themes for outcome indicators (effectiveness, patient safety, patient-centeredness) were derived. Second, by classifying the items for assessment according to the hospitalization and transition period and conducting a Delphi study to derive service items for transitional care service, during the hospitalization period, presence/absence of a caregiver and need for a caregiver, activities of daily living, and necessity for home-based care services were identified as items of high priority. Regarding patient safety, risk of falls and fractures during hospitalization, and necessity for medication reconciliation were identified as the items of high importance. For the transition period, provision of education regarding adequate responses and handling of emergencies, provision of information and guidance on application of services for basic livelihood security program beneficiaries, and education for patient skills in self-management of health were derived as items of high priority. Third, for the derivation of outcome indicators for transitional care service, in the "effectiveness" category, the experts rated a reduction in the 30-day readmission rate as an item of high importance along with a decrease in emergency department visits, reduction in preventable admissions as indicators of high relevance. In terms of "patient safety," a decrease in drug adverse reactions, and reduction in the incidence of falls and pressure ulcers were identified as indicators of high priority. Finally, for the category of "patient-centeredness," patient experience assessment, level of service satisfaction reported by patients and their caregivers, and reducing burden on caregivers were identified as indicators of high priority. CONCLUSION: This study suggest practical implications for the service with high relevance and necessity for transitional period. It also presented outcome indicators of transitional care service to contribute toward an improvement in the quality of care.

Study Protocol for a Hospital-to-Home Transitional Care for Older Adults Hospitalized with Chronic Obstructive Pulmonary Disease in South Korea: A Randomized Controlled Trial.

Chronic obstructive pulmonary disease (COPD) is a progressive respiratory condition characterized by persistent inflammation in the airways, resulting in narrowing and obstruction of the air passages. The development of COPD is primarily attributed to long-term exposure to irritants, such as cigarette smoke and environmental pollutants. Among individuals hospitalized for exacerbations of COPD, approximately one in five is readmitted within 30 days of discharge or encounters immediate post-discharge complications, highlighting a lack of adequate preparedness for self-management. To address this inadequate preparedness, transitional care services (TCS) have emerged as a promising approach. Therefore, this study primarily aims to present a detailed protocol for a multi-site, single-blind, randomized, controlled trial (RCT) aimed at enhancing self-management competency and overall quality of life for patients with COPD through the provision of TCS, facilitated by a proficient Clinical Research Coordinator. The RCT intervention commenced in September 2022 and is set to conclude in December 2024, with a total of 362 COPD patients anticipated to be enrolled in the study. The intervention program encompasses various components, including an initial assessment during hospitalization, comprehensive self-management education, facilitation of social welfare connections, post-discharge home visits, and regular telephone monitoring. Furthermore, follow-up evaluations are conducted at both one month and three months after discharge to assess the effectiveness of the intervention in terms of preventing re-hospitalization, reducing acute exacerbations, and enhancing disease awareness among participants. The results of this study are expected to provide a basis for the development of TCS fee payment policies for future health insurance.

Investigating the effectiveness of Socially Assistive Robot on Depression and Cognitive Functions of Community Dwelling Older Adults with Cognitive Impairments.

We evaluated a socially assistive robot (SAR) named Hyodol during a six-week intervention. This study enrolled 69 older adults with cognitive decline. To screen the eligibility, we have used the following three criteria, namely Korean-Mini-Mental Status Exam score ≤ 26). Clinical Dementia Rating 0.5-2), and Diagnostics and Statistical Manual V. Participants were divided into three groups based on their cognitive function (i.e. very mild cognitive impairment (vMCI), mild cognitive impairment (MCI), and moderate cognitive impairment (MOCI). The groups were instructed to use Hyodol at home for a six-week period. Baseline and post-intervention surveys were performed after six weeks to examine the changes in perceived health, depression, and cognitive function. The vMCI group showed a reduction in the depression score after the intervention (t = -2.447, p = 0.040), in comparison to their peers in the control group. Further, the MCI group showed an improvement in the cognitive function score after the intervention (t = 2.690, p = 0.021). No significant improvement was found among MOCI participants who used the SARs. The significance of this study was to examine whether participants with different levels of cognitive functioning would diverge after a period of intervention using the Hyodol SARs. Moreover, it presented preliminary data for services and policies for home care treatment targeted to cognitive decline in older adults.

Evaluating the Effectiveness of Rural Digital Social Prescribing in Korea: Protocol for a Cohort Study.

BACKGROUND: The UK National Health Service (NHS) has introduced a digital social prescribing (DSP) system to improve the mental health of the aging population. In Korea, an ongoing pilot social prescribing project has been implemented for older individuals in rural areas since 2019. OBJECTIVE: This research aims to develop a DSP program and to evaluate the effectiveness of the digital platform in rural areas of Korea. METHODS: This study was designed as a prospective cohort method for the development and effectiveness evaluation of rural DSP in Korea. The study divided participants into four groups. Group 1 will continuously implement the existing social prescribing program, group 2 implemented the existing social prescribing program but was switched to DSP in 2023, group 3 newly started the DSP, and the remaining group is the control. The research area of this study is Gangwon Province in Korea. The study is being conducted in Wonju, Chuncheon, and Gangneung. This study will use indicators to measure depression, anxiety, loneliness, cognitive function, and digital literacy. In the future, the interventions will implement the digital platform and the Music Story Telling program. This study will evaluate the effectiveness of DSP using difference-in-differences regression and cost-benefit analysis. RESULTS: This study was approved for funding from the National Research Foundation of Korea funded by the Ministry of Education in October 2022. The results of the data analysis are expected to be available in September 2023. CONCLUSIONS: The platform will be spread to rural areas in Korea and will serve as the foundation for effectively managing the feelings of solitude and depression among older individuals. This study will provide vital evidence for disseminating DSP in Asian countries such as Japan, China, Singapore, and Taiwan as well as for studying DSP in Korea.

Global Trends in Social Prescribing: Web-Based Crawling Approach.

BACKGROUND: Social loneliness is a prevalent issue in industrialized countries that can lead to adverse health outcomes, including a 26% increased risk of premature mortality, coronary heart disease, stroke, depression, cognitive impairment, and Alzheimer disease. The United Kingdom has implemented a strategy to address loneliness, including social prescribing-a health care model where physicians prescribe nonpharmacological interventions to tackle social loneliness. However, there is a need for evidence-based plans for global social prescribing dissemination. OBJECTIVE: This study aims to identify global trends in social prescribing from 2018. To this end, we intend to collect and analyze words related to social prescribing worldwide and evaluate various trends of related words by classifying the core areas of social prescribing. METHODS: Google's searchable data were collected to analyze web-based data related to social prescribing. With the help of web crawling, 3796 news items were collected for the 5-year period from 2018 to 2022. Key topics were selected to identify keywords for each major topic related to social prescribing. The topics were grouped into 4 categories, namely Healthy, Program, Governance, and Target, and keywords for each topic were selected thereafter. Text mining was used to determine the importance of words collected from new data. RESULTS: Word clouds were generated for words related to social prescribing, which collected 3796 words from Google News databases, including 128 in 2018, 432 in 2019, 566 in 2020, 748 in 2021, and 1922 in 2022, increasing nearly 15-fold between 2018 and 2022 (5 years). Words such as health, prescribing, and GPs (general practitioners) were the highest in terms of frequency in the list for all the years. Between 2020 and 2021, COVID, gardening, and UK were found to be highly related words. In 2022, NHS (National Health Service) and UK ranked high. This dissertation examines social prescribing-related term frequency and classification (2018-2022) in Healthy, Program, Governance, and Target categories. Key findings include increased "Healthy" terms from 2020, "gardening" prominence in "Program," "community" growth across categories, and "Target" term spikes in 2021. CONCLUSIONS: This study's discussion highlights four key aspects: (1) the "Healthy" category trends emphasize mental health, cancer, and sleep; (2) the "Program" category prioritizes gardening, community, home-schooling, and digital initiatives; (3) "Governance" underscores the significance of community resources in social prescribing implementation; and (4) "Target" focuses on 4 main groups: individuals with long-term conditions, low-level mental health issues, social isolation, or complex social needs impacting well-being. Social prescribing is gaining global acceptance and is becoming a global national policy, as the world is witnessing a sharp rise in the aging population, noncontagious diseases, and mental health problems. A successful and sustainable model of social prescribing can be achieved by introducing social prescribing schemes based on the understanding of roles and the impact of multisectoral partnerships.

Factors Associated With Caregivers' Preference for Digital Technologies to Support Older Adults.

Family members often serve as primary caregivers to their parents and relatives. Information and communication technology (ICT) plays an important role in facilitating this caregiving role through using Internet of Things (IoTs) caregiving services. However, there is limited evidence regarding factors influencing caregivers' acceptance of new technologies. The current study investigated factors affecting caregivers' intentions to use ICT-based IoTs. Chi-square test was used to contrast differences in distributions between categorical variables. Binary logistic regression was performed to identify factors associated with increased intention to use ICT-based IoTs. Male caregivers showed increased intentions of using these products and considered the psychological burden as well as the diverse factors associated with adopting IoTs. On the other hand, female caregivers considered relieving their care burdens and social influences. As such, findings indicated that female caregivers demonstrated increased intention, which is associated with their care burdens, and relieving a similar experience would be a significant motivation. Further studies are needed not only for specific measures to reduce psychological burden but also for physical burden. Marketing strategies for spreading awareness of IoT technologies require more investment and initiatives. [Journal of Gerontological Nursing, 48(8), 33-41.].

Associations Between Compliance With Non-pharmaceutical Interventions and Social-distancing Policies in Korea During the COVID-19 Pandemic.

OBJECTIVES: This study explored changes in individuals' behavior in response to social distancing (SD) levels and the "no gatherings of more than 5 people" (NGM5) rule in Korea during the coronavirus disease 2019 (COVID-19) pandemic. METHODS: Using survey data from the COVID-19 Behavior Tracker, exploratory factor analysis extracted 3 preventive factors: maintenance of personal hygiene, avoiding going out, and avoiding meeting people. Each factor was used as a dependent variable. The chi-square test was used to compare differences in distributions between categorical variables, while binary logistic regression was performed to identify factors associated with high compliance with measures to prevent transmission. RESULTS: In men, all 3 factors were significantly associated with lower compliance. Younger age groups were associated with lower compliance with maintenance of personal hygiene and avoiding meeting people. Employment status was significantly associated with avoiding going out and avoiding meeting people. Residence in the capital area was significantly associated with higher compliance with personal hygiene and avoiding venturing out. Increasing SD levels were associated with personal hygiene, avoiding going out, and avoiding meeting people. The NGM5 policy was not significantly associated with compliance. CONCLUSIONS: SD levels, gender, age, employment status, and region had explanatory power for compliance with non-pharmaceutical interventions (NPIs). Strengthening social campaigns to inspire voluntary compliance with NPIs, especially focused on men, younger people, full-time workers, and residents of the capital area is recommended. Simultaneously, efforts need to be made to segment SD measures into substrategies with detailed guidance at each level.

The Association with COPD Readmission Rate and Access to Medical Institutions in Elderly Patients.

Purpose: Up to 20% of patients with chronic obstructive pulmonary disease (COPD) require re-admission within 30 days of discharge after hospitalization for acute exacerbations of the disease. These re-admissions can increase morbidity and the economic burden of COPD. Reducing re-admissions has become a policy target in many developed countries. We investigated the risk factors for COPD re-admissions among older adults with COPD. Patients and Methods: Data obtained from the National Health Insurance Service-Senior Cohort (NHIS-SC) in Korea were analyzed. The subjects included 558,147 patients aged ≥70 who had been admitted for COPD between 2013 and 2015. Re-admission was defined as being re-hospitalized within 30 days after discharge. The key variables selected from the database included income-based insurance contributions, demographical variables, information on inpatient medical services, types of healthcare facilities, and emergency time relevance index (TRI). The TRI is a regional medical-use analysis index that evaluates whether the capacity of the medical services available is appropriate for the medical needs of the target residents. Results: In 814 COPD re-admission cases among 4867 total admissions due to COPD in elderly subjects, higher re-admission rates were associated with male sex, admission to district hospitals, medical aid recipients, and a longer hospital stay. When additionally adjusting the TRI to identify the difference in re-admission rates due to medical service accessibility, the same results were found, except for the areas of residence. The TRI was lower in re-admission cases (odds ratio 0.991 [95% CI, 0.984‒0.998], P = 0.013). Conclusion: In this study, COPD re-admission rates among older adults were significantly associated with sex, length of hospital stay, and the type of hospital. The capacity of the medical services provided was also related to the COPD re-admission rate. Better access to appropriate emergency services is associated with reduction of COPD re-admission rates.

Mediating Effects of Smartphone Utilization between Attitude and Willingness to Use Home-Based Healthcare ICT among Older Adults.

OBJECTIVES: This study explored the direct and indirect effects of knowledge of new technology (e.g., artificial intelligence, the Internet of Things, and the Fourth Industrial Revolution), attitudes towards technology use, and smartphone utilization skills on older adults' willingness to use home-based information and communication technology (ICT) for self-health management. METHODS: A phone survey was conducted among 300 older adults aged 65 or older in Gangwon Province, Republic of Korea. A path analysis was performed to identify the direct and indirect effects of knowledge of new technology, attitudes towards technology use, and smartphone utilization skills on willingness to use home-based healthcare ICT. Socioeconomic variables were used as control variables. RESULTS: Knowledge of new technology, but not attitudes towards technology use, had a direct impact on smartphone utilization skills. Attitude towards technology use and smartphone utilization skills showed significant effects on willingness to use home-based healthcare ICT. One standard unit change in attitudes towards technology use contributed to a 0.172 unit change in willingness (p = 0.001), and one standard unit change in smartphone utilization skills changed willingness by 0.246 units (p < 0.001). In addition, older adults with a higher education level and economic status, and lower self-related health status, were more willing to use home-based healthcare ICT. CONCLUSIONS: These findings underscore the necessity of enhancing the smartphone utilization skills of older adults and attitudes towards technology use. Providing more user-friendly services and increasing smartphone utilization skills among older adults would contribute to willingness to use home-based ICT for healthcare management.

Development of a Transitional Care Model Program for Patients with Pneumonia, Asthma, and Chronic Obstructive Pulmonary Disease: In-depth Interviews with Readmitted Patients.

Community-based health management policies are needed considering societal aging. We aimed to develop a transitional care model (TCM) program for patients with pneumonia, asthma, and chronic obstructive pulmonary disease. First, we conducted in-depth interviews with patients who were hospitalized, released, and readmitted for those three conditions to identify issues with the current hospitalization/discharge system and post-discharge processes. Next, we developed a new TCM program suited to the realities of the current medical environment. Interviews revealed problems including inadequate awareness of disease and health management; insufficient information exchange between patients, caregivers, and primary medical institutions; and absence/low usage of community-based care services. The investigation applying the new TCM program to patients and following up on readmission rates and life satisfaction after discharge is ongoing. Reviewing these results and conducting further studies in the future will allow improvements to the model.

Gap between Perceived eHealth Literacy and Ability to Use Online Cancer-Related Information.

BACKGROUND: The effective evaluation of health information available online is an important skill. However, consumers' self-perceptions of their eHealth literacy levels do not reflect their actual capabilities. The goal of this experimental study of online search behavior is to identify differences between self-perceived eHealth literacy and actual ability to use the accuracy of cancer information available online. METHODS: Thirty-one adults participated in the study conducted on July 15 and 16, 2017. We first measured perceived eHealth literacy and then asked participants 5 questions concerning cancer. Bandicam (v3.3.0) and BrowsingHistoryView were used to record search behavior and uniform resource locators, respectively. A Mann-Whitney U test and Fisher's exact test were performed. RESULTS: The results showed that participants most frequently searched for cancer information on blogs and café websites. Regarding search behavior, those who perceived higher knowledge in available resources tended to solve the given problem with significantly smaller number of webpages to answer a weight management question. Participants who perceived higher knowledge in helpfulness of information tended to use significantly smaller number of webpages to answer questions on red ginseng's preventive effects on caner and weight management. However, there was no proof that the high eHealth literacy group had significantly higher rates of correct answers than the low eHealth literacy group. Further, regarding cancer screening, the rates of correct answers were low for groups who considered their ability higher to find helpful resources and perceived higher knowledge in helpfulness of information. CONCLUSION: There is a gap between perceived eHealth literacy and the actual ability to use online cancer-related information. To fundamentally improve eHealth literacy, it is important to evaluate the actual abilities concerning each eHealth literacy component and to provide customized education.

Understanding Facilitators and Barriers of Online Cancer Information Utilization among Cancer Survivors and their Families: Focus on the Theory of Planned Behavior.

OBJECTIVE: Cancer survivors have various health care needs and are willing to be proactive with their health maintenance. Online information would be a useful resource to guide cancer survivors and their family members. Therefore, identifying the factors that influence Internet searching behaviors among cancer survivors and their family members is a first step toward providing better health care services for cancer care. METHODS: We performed focus group interviews that were based on the Theory of Planned Behavior, with thirty-one participants to explore factors related to Internet search behaviors among cancer survivors and their family members. RESULTS: Six themes were identified in the analysis of participant interviews. Attitudes toward searching for health information on the Internet included the themes "Fulfilling unmet needs" and "Confirmation through second opinion." Themes related to social norms included "a required step for sure" and "helping each other." In terms of perceived behavioral control, themes included "difficult to choose because of being 'overwhelmed with information,'" and "complex searching milieu." CONCLUSION: It was clear that cancer survivors and their family members had unmet needs for maintaining their health status. They wanted to be informed and actively involved in the decision-making process regarding health management. Consultation and education provided to patients by doctors should not only include information on diet and nutrition but also information on the resulting complications to satisfy their need for reliable health information.

What quality factors matter in enhancing the perceived benefits of online health information sites? Application of the updated DeLone and McLean Information Systems Success Model.

BACKGROUND: Despite a growing need for designing and monitoring health information sites through comprehensive examination of the various elements of website quality, there is little research that systematically models and presents such examinations. OBJECTIVES: Applying the updated DeLone and McLean Model of Information Systems Success, this research aimed to examine how health information sites' information quality, system quality, and service quality lead to user satisfaction and perceived benefits. METHODS: This research was conducted in a specific context of the National Health Information Portal (NHIP), a governmental health information site in South Korea. We conducted online survey in 2017, with 506 adults from the NHIP consumer panel. Data were analyzed using a confirmatory factor analysis, hierarchical ordinary least squares regression, and bootstrapping approach for a mediation test. RESULTS: Of the three quality factors, information quality had significant associations with all outcome variables: user satisfaction, intention to reuse the site, and perceived benefits of site use in health settings. There were also indirect paths from information quality to perceived benefits, one mediated through intention and the other mediated through satisfaction and then intention. Service quality had a significant association with user satisfaction, and its impact on perceived benefits occurred indirectly through user satisfaction and intention in serial. By contrast, the role of system quality received no empirical support. IMPLICATIONS: The results offer theoretical and practical implications for how to enhance the effectiveness of online health information sites.

Evaluation of Food Labeling Policy in Korea: Analyzing the Community Health Survey 2014-2017.

BACKGROUND: As Koreans adopt more Westernized diets, consumer demands for processed food products are growing. The Korean government implemented a food labeling system to help people reasonably choose processed foods. This study investigated the utilization of these food labels among Koreans, as well as demographic differences between users and non-users of food labels, ultimately presenting foundational data for strategies to enhance dietary lifestyles by facilitating the use of food labeling. METHODS: Data from the 2014-2017 Community Health Survey were used. The Cochran-Armitage trend test was performed to investigate whether food labeling awareness and utilization increase over time; a data mining technique called decision tree analysis was then used to examine the effects of sociodemographic factors on the use of food labeling for each of the 4 years. RESULTS: Food labeling awareness increased by 4.5% over 4 years; the Cochran-Armitage trend test showed that this increase was statistically significant (χ² = 1,068.21; P < 0.001). Food labeling utilization increased significantly but marginally, by 0.3%, over 4 years (χ² = 20.154; P < 0.001). Decision tree analysis showed that food labeling users comprised mainly women in their 30s-50s currently in graduate school or with a graduate degree; the non-user group comprised mainly divorced/widowed/separated people in their 70s who were elementary school grads or below. CONCLUSION: Education level, which could be related to health literacy, substantially affected the use of food labeling. Education level is a typical socioeconomic index, and if people who are less educated tend not to use food labeling, it can lead to health inequity. Thus, food labeling should be reformed with consideration of health literacy among the less-educated social classes. From a health communication perspective, images and pictures can boost consumers' understanding, which should be considered to improve comprehensibility of food labeling.

A scoping review of consumer needs for cancer information.

OBJECTIVE: This study was a scoping review of research on cancer-related health information seeking and needs of patients, survivor, non-patients, and caregivers. METHODS: This study used the COSI model to search for articles published from 2007 to 2017. RESULTS: In total, 117 articles with titles and abstracts including the following terms were selected: cancer, health, information, seeking. Non-patients obtained information from the Internet, doctors, and media, whereas patients obtained information from doctors, the Internet, and media. Information needs were the highest for treatment, prognosis, and psychosocial support. Patients had the highest need for information on prognosis and treatment, whereas non-patients had the highest need for general cancer information, prevention, and cancer examination. Caregivers sought information about treatment, psychosocial support, and prevention. CONCLUSION: This study revealed an increase in the number of research articles identifying cancer patients' information needs. Cancer patients rely on health professionals for information; thus, relevant materials are needed. Furthermore, not only medical but also psychosocial support information is needed. PRACTICE IMPLICATIONS: There is a need for cancer information from health professionals, and thus for patient-centered training materials. Furthermore, a survey system to evaluate consumers' cancer information needs should be developed.

Analysis of the Factors Affecting Consumer Acceptance of Accredited Online Health Information.

With the increasing use of the internet and the spread of smartphones, health information seekers obtain considerable information through the internet. As the amount of online health information increases, the need for quality management of health information has been emphasized. The purpose of this study was to investigate the factors affecting the intention of using accredited online health information by applying the extended technology acceptance model (Extended-TAM). An online survey was conducted from September 15, 2016 to October 3, 2016, on 500 men and women aged 19-69 years. The results showed that the greatest factor influencing the acceptance of the accredited health information was perceived usefulness, and the expectation for the quality of the accreditation system was the most important mediator variable. In order to establish the health information accreditation system as a means to provide easy and useful information to the consumers, it is necessary to carry out quality management and promote the system through the continuous monitoring of the accreditation system.
