    Effects of web-based palliative wound care education using the clinical judgment model: A quasi-experimental study with facilitylevel random allocation

    by Sung Ok Chang, Dayeong Kim, Young-Rim Choi, Dai-Young Kwon, Ye-Na Lee

    Purpose: Nursing homes face a growing demand for high-quality palliative wound care. Nursing home staff require not only knowledge but also clinical judgment to address the complex needs of residents at the end of life. This study aimed to develop and evaluate a web-based palliative wound care education program using a clinical judgment model. Methods: An educational program was developed using the ADDIE model through needs analysis with 10 nursing home staff, program design and development, and pilot implementation and evaluation. Program effectiveness was evaluated in a quasi-experimental study with facility-level random allocation. Four nursing homes were randomly allocated to the experimental or control condition, and 52 nursing home staff were included in the final analysis (n=26 per group). The experimental group received clinical judgment model-based web education, whereas the control group received general web-based palliative wound care education without the clinical judgment model. Clinical judgment was assessed before and after the intervention using nonparametric tests. Results: Both groups showed significant improvements in clinical judgment. However, the experimental group demonstrated greater improvements than the control group in noticing (Z=-3.91, p<.001), interpreting (Z=-3.39, p=.001), responding (Z=-3.64, p<.001), reflecting (Z=-2.30, p=.021), and the total clinical judgment score (Z=-4.62, p<.001). Conclusion: The findings support the effectiveness of clinical judgment model-based education in improving clinical judgment in palliative wound care. This web-based approach supports continuing education and improves care quality in nursing homes.

    How do interdisciplinary practitioners conceptualize infection control in nursing homes during the COVID-19 pandemic?

    by Sung Ok Chang, Min Sun Park

    During the recent global pandemic, nursing home (NH) residents were among the most vulnerable, yet empirical insights into how practitioners conceptualized and implemented infection control in NHs were limited. This study aimed to explore the ways in which interdisciplinary NH practitioners understood and conceptualized infection control in response to emerging infectious diseases and to identify a structural framework derived from their perceptions. A qualitative phenomenographic research design was employed. In-depth interviews were conducted with 21 interdisciplinary practitioners from three NHs. Data were analyzed using the seven-step phenomenographic approach. Two overarching categories were identified: "assessments based on vulnerability" and "interventions focused on prevention," each consisting of sub-categories that reflected practitioners' ways of understanding infection control. A hierarchical outcome space was developed to illustrate the dynamic and cyclical nature of infection control in NHs. The findings highlight the need for a proactive, interdisciplinary approach tailored to the unique environment of NHs. This framework may guide future educational initiatives and provide a practical reference for training new practitioners lacking pandemic experience.

    by Young-Rim Choi, Ye-Na Lee, Dayeong Kim, Sung Ok Chang

    Purpose: Infection control is a critical concern in nursing homes, especially in the post-COVID-19 era, due to the frailty and complex health conditions of older adults. This study aimed to develop an educational framework to improve infection control practices in nursing homes. Methods: We interviewed five infection specialists to gain practical insights. Subsequently, we administered three rounds of Delphi surveys to 20 nursing home practitioners to assess the validity and practicality of the selected items, thereby establishing a comprehensive framework. Results: The interview data revealed three key categories: recipient-centered, interaction-centered, and environment-centered. Following the Delphi surveys, we identified seven crucial factors for practicality in nursing homes: the characteristics of residents’ health, detection of subtle changes, identification of nonverbal signs, effective communication among professionals, feedback and assessment among professionals, following infection control principles, education based on problem-solving, and immunization and isolation strategies for creating a safe environment. Conclusion: By integrating expert insights and validating the framework through the Delphi technique, the proposed framework enhances infection control training and education programs in nursing homes, ultimately ensuring resident safety.

    Current State and Future Trends of Research on Pressure Injuries in Nursing Homes: Network Analysis and Topic Modeling

    by Sung Ok Chang, Ye-Na Lee

    Background: Pressure injuries (PIs) are a significant issue in nursing homes (NHs) that affect residents’ physical, psychological, and financial well-being. Despite advancements in prevention and management, PIs remain a critical challenge requiring a comprehensive analysis of research trends to guide future efforts.Methods: We analyzed 1,857 research abstracts published up to December 2023 using text network analysis and topic modeling. Keyword frequency, co-occurrence patterns, and centrality metrics were examined to identify the key terms. Latent Dirichlet allocation was employed for topic modeling, and trends were analyzed over decades to explore the evolution of research priorities.Results: The most frequent keywords were “patient,” “care,” and “wound,” emphasizing the central themes of patient care and wound management. Four main topics were identified: Managing PI Complications, Preventing PIs and Maintaining Skin Integrity, Improving Organizational Strategies for PI Care, and Managing Systemic Conditions in PI Care. Trends revealed a decline in studies on post-injury management, while prevention and organizational strategies have gained prominence. Patient-specific risk factors have consistently attracted attention over the decades, highlighting the importance of individualized care.Conclusion: This study underscores the shift from reactive post-injury management to proactive prevention and organizational strategies in PI research. These findings emphasize the need for integrated approaches that combine patient-centered care with systemic and preventive measures to improve outcomes in NHs.

    How Nursing Home Nurses Who Care for Residents With Dementia Experience the Moral Distress? A Phenomenography Study

    by Eun Young Kim, Ye‐Na Lee, Sung Ok Chang

    Aim: Exploring how nursing home nurses who care for residents with dementia experience moral distress.Design: A qualitative phenomenography design.Methods: Phenomenography was used in this qualitative study. In‐depth interviews were conducted with 20 nurses caring for residents with dementia at three nursing homes using phenomenographic analysis.Results: Six categories were divided into two groups. The ‘reflection on my nursing’ group included the categories ‘anguish over qualifications to care for residents’, ‘uncertainty about the adequacy of the care provided’, and ‘internal conflict over whether to compromise with unsatisfactory outcomes’. The ‘moral awareness’ group included ‘being aware of deviations from the standards I set and the care I provide’, ‘recognising when I become insensitive to things I should not do’, and ‘ruminating about whether it would be okay if I have no choice’. Comprehensively, it was found that moral distress occurs when reflecting on nursing and moral awareness conflicts.Conclusion: This study provides insight into the various ways in which nursing home nurses experience moral distress when caring for residents with dementia. This study can provide a basis and direction for various strategies to reduce moral distress.Implication for the Profession and/or Patient Care: Considering the growing interest in the moral distress experienced by nurses, along with the importance of the human rights of residents with dementia in an aging society, these research results will have a positive impact on improving the quality of care provided by nursing home nurses to residents with dementia.Patient or Public Contribution: No patient or public contribution.Reporting Method: We have adhered to relevant COREQ guidelines.

    Adaptive Learning for Behavioral and Psychological Symptoms of Dementia in Nursing Homes: A Quasi-Experimental Study

    by Dayeong Kim, Young-Rim Choi, Ye-Na Lee, Won Hee Park, Dai-Young Kwon, Sung Ok Chang

    Continuing education in nursing homes (NHs) is facing a transition to distance learning, such as web-based education, as demonstrated during the COVID-19 pandemic. Since behavioral and psychological symptoms of dementia (BPSD) are managed through integrative direct care by nursing staff, including nurses, nursing assistants, and care workers with diverse educational backgrounds and needs, an effective and efficient web-based education program with a concrete pedagogical and theoretical basis is essential. Therefore, this study aimed to develop an adaptive learning web-based BPSD education system for NH nursing staff. The adaptive learning web-based BPSD education program, with an embedded artificial intelligence chatbot, was developed based on the frameworks of BPSD education and adaptive learning models. The educational program was evaluated using a multisite, single-blinded, quasi-experimental design. Fifty-eight nursing staff were recruited from five different NHs. The experimental group received an adaptive learning system that tailored content to prior knowledge, while the control group received a non-adaptive web-based system. The results from the analysis indicated that all components of learning effectiveness, including BPSD competence, BPSD knowledge, and self-efficacy, were significantly improved in the experimental group compared with the control group. System satisfaction was significantly higher in the experimental group than in the control group, and 75% of the participants in the experimental group actively adapted their individual educational content. These findings indicate that the adaptive learning system had positive outcomes on learning and system effectiveness, suggesting an innovative strategy toward a “new normal” education for NH nursing staff in the post-COVID-19 era.
