This narrative review aimed to (1) map the global research landscape of artificial intelligence (AI) in dementia care, (2) characterize domestic Korean research, and (3) propose priority directions for nurse-led AI research. Methods: International literature was retrieved from PubMed (January 2015 to December 2025; n=5,710) and analyzed using VOSviewer with the Leiden algorithm. Korean literature from RISS (n=265) was synthesized narratively. Results: Publications increased substantially since 2015, with acceleration after 2024 driven by large language models. Five thematic clusters emerged: (1) care, daily living, and digital health; (2) aging and brain structure; (3) risk prediction and clinical data; (4) early screening and behavioral biomarkers; and (5) Alzheimer’s diagnosis and deep learning. Four domains were most relevant to nursing: monitoring technologies, digital biomarkers, AI chatbots for caregivers, and clinical decision support systems. Korean research concentrated on emotional support robots with methodological limitations. Conclusion: Rigorous nurse-led trials with multidimensional outcomes are needed to establish AI’s clinical value in dementia nursing.

This study aimed to explore the hospitalization experiences of elderly surgical patients and understand the meaning of these experiences. Methods: Data were collected through individual in-depth interviews with 10 elderly patients who underwent general anesthesia surgery at Ewha Womans University Seoul Hospital and were analyzed using Colaizzi’s phenomenological analysis method. Results: Four theme clusters and ten themes were identified. The theme clusters were “Limitations faced due to aging,” including themes of cognitive and physical decline. “Psychological retreat after undergoing surgery” encompassed role loss, feelings of guilt, and a sense of alienation, respectively. “Loss of freedom in inpatient life after surgery” highlighted dietary restrictions and physical dependence and “Concerns about life after discharge” reflected uncertainties, burdens, and negative thoughts about life. Conclusion: This study underscores the need for holistic nursing interventions that address not only the physical but also the psychological and social needs of elderly surgical patients. It also emphasizes the importance of effective communication strategies, emotional support, and post-discharge care. These findings provide foundational data for the development of tailored nursing practices and policies for elderly surgical patients.

This study aimed to determine high-risk groups and develop a predictive model of hearing loss among adults in South Korea. Methods: We analyzed 1,873 participants aged 40 years and older using the Korean National Health and Nutrition Examination Survey (KNHANES). Complex sample analysis and decision tree analysis were conducted. Results: Among the participants, 764 (36.0%) had hearing loss, with 54.5% aged 65 or older. The decision tree analysis identified age as the most significant predictor, revealing six high-risk groups: five in older adults and one in middle-aged adults. The characteristics of high-risk groups varied by age group. In high-risk groups among older adults, sarcopenia, self-reported health status, and economic activity were key predictors, whereas in middle-aged groups, education level and lifestyle factors such as self-reported oral health played a major role. The highest-risk group was older adults with sarcopenia, with 81.3% experiencing hearing loss. Conclusion: It is essential to implement age-specific strategies to effectively prevent and manage hearing loss. For older adults, strengthening support systems to address sarcopenia, enhance perceived health status, and reduce social isolation is crucial. For middle-aged adults, prevention should focus on health management, lifestyle modifications, and improved accessibility to healthcare.

This study was conducted to confirm the provision standards and appropriateness of functional recovery training services performed on residents in long-term care facilities. Methods: Twenty-eight service providers working in four long-term care facilities applied the functional recovery training services to 63 older residents for 15 days, integrating them with their existing daily tasks. The contents recorded by the service providers on checklists were analyzed, and the experiences of applying functional recovery training services by the service providers were examined through focus group interviews. Results: Training for activities of daily living, excluding bathing, five items such as dressing and undressing are performed 2 to 4 times per day. The duration for one session is approximately 16 minutes for meals, around 10 minutes for bathing, and about 5 to 7 minutes for the remaining activities. Movement and walking training, covering five items like standing, occurs 2 to 3 times per day, with session durations ranging from 3 to 10 minutes. Physical activity training is conducted 1 to 2 times per day, with each session lasting about 5 to 7 minutes. Cognitive activity training is performed 1 to 2 times per day, with each session lasting approximately 4 to 7 minutes. Conclusion: For functional recovery training to be established in long-term care facilities, it is crucial to share an accurate understanding of the concept of training. Prior to the provision of training services, appropriate personnel such as nurses need to comprehensively assess the individuals and plan the training accordingly.

This study synthesized the literature on constipation among Korean older adults in long-term care (LTC) facilities. Methods: This scoping review utilized the Joanna Briggs Institute protocol. We conducted a literature search using Cumulative Index to Nursing and Allied Health, PubMed, PsycINFO, Korean databases Research Information Sharing Service, Korean Studies Information Service System, and ScienceON. Two reviewers independently selected the studies and extracted their characteristics using pretested forms to determine the final inclusion. In total, 473 articles were identified, and eight were used for the final analysis. Results: Quasi-experimental design was the most common research design. Sex, age, state of mobility, admission periods, LTC classification, sleep satisfaction, depressive symptoms, diet type, daily fluid intake, and history of digestion were identified as factors related to constipation. The most widely used constipation measurement method is measuring the frequency of defecation per week. Massage is the most commonly used nursing intervention to relieve constipation. Conclusion: The diversification of research on constipation is necessary to improve the quality of life of older adults living in LTC facilities. Therefore, the use of reliable tools to determine constipation in older adults in LTC facilities should be expanded. There is a need to develop and implement diverse non-pharmacological interventions for older adults in LTC facilities. The results of this study are intended to serve as a basis for the development of constipation programs for Korean older adults in LTC facilities.

Purpose: This scoping review aimed to identify the research trends for dysphagia among older Korean adults in long-term care facilities. Methods: A literature search was performed using Korean Studies Information Service System, Research Information Sharing Service, ScienceON, Cumulative Index to Nursing and Allied Health Literature, and PubMed. A total of 1,395 articles were identified, and 10 articles were selected for the final analysis. Two reviewers independently performed the study selection and extraction using pre-tested forms to confirm those for final inclusion. Results: Most of the studies were published between 2011 and 2014. The quasi-experimental design was most frequently applied. The Gugging Swallowing Screen was the most widely used assessment tool. All studies, including dysphagia intervention programs, involved oral and facial exercise programs. In addition, they all used swallowing-related outcome variables to assess the effectiveness of the interventions. Conclusion Additional studies on dysphagia among older Korean adults in long-term care facilities should be conducted, and various interventions and assessment tools should be developed and implemented. This study is anticipated to establish a fundamental foundation for further dysphagia-related research and help improve the quality of life of Korean older adults in long-term care.

Purpose: : This scoping review was designed to identify gaps in knowledge and guide future directions for clinical nursing practices and research on oral hygiene care for endotracheally intubated patients in Korean intensive care units. Methods: : We conducted a scoping review using the methodological framework proposed by Arksey and O’Malley. PubMed, CINAHL, RISS, Science On, and DBpia databases were searched. Two reviewers independently selected the studies and extracted data. A total of 445 studies were identified, of which 17 were included in the final analysis. Results: : No research has been conducted from 2021 to the present. A total of 12 instruments were utilized in 13 studies to assess the effectiveness of oral hygiene care. All studies investigating the effectiveness of oral hygiene care have consistently documented that chlorhexidine has the most significant effect. The frequency and time of oral hygiene care were each examined in one study. Conclusion : A research study is necessary to develop a measurement tool for assessing the effectiveness of oral hygiene care suitable for endotracheal intubated patients in intensive care units. Interventional studies should be conducted to determine the effects of chlorhexidine and the appropriate frequency and time of oral hygiene care. Thereafter, revision of domestic evidence-based clinical practice guidelines by integrating these results will be necessary.

Purpose: This study synthesized the literature on eating difficulties among older adults with dementia in long-term care facilities. Methods: A scoping review, using the framework proposed by Arksey & O'Malley (2005) and supplemented by Levac et al. (2010), was conducted. Literature was searched from RISS, KISS, DBpia, PubMed, and CINAHL. Two reviewers independently selected studies and extracted their characteristics, using pre-tested forms to determine final inclusion. In total, 1283 articles were identified, and 13 articles were used for the final analysis. Results: The Eating Behavior Scale and the Edinburgh Feeding Evaluation in Dementia scale were the most widely utilized measurement tools. The most common factors related to eating behavior in older adults with dementia were cognitive and physical functions in the individual domain, the caregiver's attitude toward eating in the inter-individual domain, and meal type in the environmental domain. Conclusion Measurement tools reflecting the eating behavior of older adults with dementia must be developed to obtain a comprehensive understanding of this issue and create effective interventions for the specific context of long-term care facilities in Korea. The results of this study are intended to serve as a basis to develop meal support programs for older adults with dementia.
