Frailty Assessment Scale for Heart Failure: Development and Psychometric Validation.

BACKGROUND: Frailty is common in patients with heart failure. Specific scales, including the Clinical Frailty Scale, exist but have not undergone thorough psychometric validation among patients with heart failure. OBJECTIVE: The aim of this study was to develop and validate the Frailty Assessment Scale for Heart Failure (FAS-HF) in patients with heart failure. METHODS: This study included 3 phases. In phase I, conceptualization and item generation, the FAS-HF was initially developed through the analysis of qualitative research data and a literature review. In phase II, item selection and content validity, the Delphi method was used to gather experts' opinions and suggestions regarding the FAS-HF. In phase III, field testing and psychometric evaluation, a cross-sectional study of 184 patients with heart failure in northern Taiwan was conducted to test the reliability and validity of the FAS-HF. RESULTS: The 15-item FAS-HF included the physical, psychological, and social frailty domains. The total score ranged from 0 to 45, with higher scores representing frailer individuals. Exploratory factor analysis revealed that the cumulative loading variance was 57.39%. In the confirmatory factor analysis, the goodness-of-fit index (0.91), adjusted goodness-of-fit index (0.87), and root mean square error of approximation (0.06) were acceptable for model fit. Acceptable reliability was found, with a Cronbach α coefficient of 0.87 and a test-retest reliability of 0.99. Compared with the Fried frailty phenotype, the area under the receiver operating characteristic curve was 0.94, and the optimal cutoff score for frailty was 20. CONCLUSIONS: The FAS-HF has good reliability, validity, and discrimination and can be used as a frailty indicator for patients with heart failure.

The Lived Experience of Frailty in Patients Aged 60 Years and Older with Heart Failure: A Qualitative Study.

PURPOSE: The prevalence of frailty among patients with heart failure is about 45%. Frailty may result in patients' functional decline, falls, disability, and decreased quality of life. Qualitative studies can explore older patients' perceptions of frailty and help patients cope with it. However, a qualitative approach that explores the experience of frailty in older patients living with heart failure is lacking. This study aimed to explore the lived experience of frailty in older patients with heart failure. METHODS: This qualitative study applies Giorgi's phenomenological method. Data were collected from October 2019 to August 2020. Thirteen older patients with heart failure aged at least 60 years were recruited using purposive sampling from a medical center in Taiwan. The participants participated in an in-depth interview using a semistructured interview guide. RESULTS: Seven themes were identified: "being reborn at the end of the road but having difficulty recovering", "living with a disease with an ineffable feeling", "feeling like being drained: physical weakness and a dysfunctional body", "struggling with impaired physical mobility and facing unexpected events", "suffering from mental exhaustion", "receiving care from loved ones", and "turning over a new leaf". CONCLUSIONS: Frailty in older patients with heart failure was obscure and difficult to describe. Frailty could be improved by medical intervention, self-management, and social support but was difficult to reverse. Patients with heart failure should be evaluated for frailty using multidimensional assessment tools at first diagnosis and provided frailty-related information so that patients have proper insight into their disease as early as possible.

The effects of an immersive 3d interactive video program on improving student nurses' nursing skill competence: A randomized controlled trial study.

BACKGROUND AND OBJECTIVE: Acquired accurate clinical nursing skills are among the most important core nursing competencies for nursing students, as nursing students' inadequate skill capacities might endanger patients safety. Therefore, it is essential to develop teaching strategies to strengthen students' nursing skills. This study examined the effects of an immersive three-dimensional (3D) interactive video program on improving nursing students' nasogastric tube feeding skill competence. DESIGN: A randomized controlled trial research design. SETTINGS AND PARTICIPANTS: Forty-five nursing students from a university in northern Taiwan. METHODS: The students were randomly assigned to an intervention group (n = 22) and a comparison group (n = 23). The intervention group received the immersive 3D interactive video program on nasogastric tube feeding, whereas the comparison group watched a regular demonstration video. The questionnaire was used to collect data before the intervention, immediately after the intervention, and one month after the intervention. RESULTS: Nursing students' knowledge and confidence in nasogastric tube feeding were significantly improved after the intervention in both groups. Although there were no significant differences in students' knowledge, skill, and confidence between the two groups, participants' average satisfaction score with the immersive 3D interactive video program in the intervention group was significantly higher than in the comparison group that watched a regular video (t = 2.302, p = 0.026). CONCLUSIONS: The findings of this study showed that both immersive 3D interactive video program and regular demonstration video could improve nursing students' learning outcomes. The higher satisfaction score in the intervention group indicates that learning through immersive 3D interactive video is acceptable and satisfactory. This study provides useful information for nursing faculty members for designing and developing teaching methods for the acquisition of nursing skills. It can also serve as a reference for further studies relating to AR, VR, or immersive learning materials.
