Objective:To analyze the effect of exercise intervention based on the transtheoretical model on sedentary time and exercise adherence in elderly patients with stroke.Methods:A convenience sample of 60 elderly patients with stroke who visited Fuyang Hospital Affiliated to Anhui Medical University and were registered in community health records between December 2023 and August 2024 was recruited. Participants were randomly assigned to the intervention group ( n=30) and control group ( n=30). The intervention lasted 28 weeks. The control group received standardized home-based exercise program, while the intervention group received exercise intervention based on the transtheoretical model. Sedentary time, exercise adherence, and exercise self-efficacy were assessed before intervention, at week 16, and at week 28. Results:A total of 28 participants in each group completed the study. Sedentary time in the intervention group showed a continuous downward trend over the intervention period and was significantly lower than that in the control group at weeks 16 and 28 ( P<0.05). Exercise adherence in the intervention group was significantly higher at week 28 ( P<0.001). Exercise self-efficacy was significantly higher at week 16 and further improved at week 28 compared with the control group ( P<0.05) . Conclusions:An exercise intervention program designed based on the transtheoretical model can effectively reduce sedentary time, improve exercise adherence, and enhance exercise self-efficacy in elderly patients with stroke.

Objective:To explore the barriers encountered by nurses in managing cognitive frailty in elderly patients with chronic heart failure (CHF) .Methods:Using purposive sampling, 15 nurses working in the Cardiovascular and Geriatric Departments of Fuyang Hospital of Anhui Medical University were recruited for semi-structured interviews from January to April 2024. The interview guide was developed based on the Theoretical Domains Framework (TDF), and data were analyzed using thematic analysis.Results:The study identified barriers related to five TDF domains: knowledge/skills, beliefs about consequences, motivation and goals, environmental context and resources, and behavioral regulation. Further refinement revealed specific challenges, including a lack of systematic knowledge and skills in cognitive frailty management for elderly CHF patients, inadequate incentive mechanisms, limited policy support from government and healthcare institutions, and the absence of standardized management protocols for cognitive frailty.Conclusions:Nurses face multiple barriers in managing cognitive frailty in elderly CHF patients. Addressing these challenges requires strengthening training on cognitive frailty knowledge and skills, improving incentive mechanisms, enhancing policy support from governments and healthcare institutions, and establishing standardized quality management systems to enhance nurses' ability to manage cognitive frailty in elderly CHF patients.
