OBJECTIVE: Exploring the effects of the hospital-to-home transitional capacity management plan in patients with chronic heart failure. METHODS: Patients with chronic heart failure who were hospitalized from December 2022 to August 2024 were selected as research subjects and randomly assigned to either a control group or an observation group, with 96 cases in each group. The control group received the conventional nursing plan, while the observation group received the hospital-to-home transitional volume management plan. The main outcome indicator was the rate of achieving dry weight targets two months after discharge. Secondary outcome indicators included self-care ability, and other outcome indicators included 6-minute walking distance and readmission rate. These outcomes were compared between the two groups. RESULTS: Two months after discharge, the rate of achieving normal body weight in the observation group was higher than in the control group (P < 0.05), The 6-minute walking distance in the observation group was greater than in the control group (P < 0.05), The scores for self-care maintenance, self-care management, and self-care confidence in the observation group were all higher than those in the control group (P < 0.05), and the readmission rate in the observation group was lower than that in the control group (P < 0.05). CONCLUSION: The hospital-family transitional volume management program enhance the self-capacity management ability of patients with chronic heart failure, stabilize the volume load status, and provide a reference for self-capacity management of patients with chronic heart failure.
