Study Title:A Nurse-Led Intervention Program Based on the Common-Sense Model of Self-Regulation for Volume Management in Patients with Chronic Heart Failure: A Randomized Controlled Trial
Brief Summary:
The goal of this clinical trial is to learn if a nurse-led, theory-driven intervention based on the Common-Sense Model of Self-Regulation (CSM), supplemented by Bandura's Self-Efficacy Theory, works to improve volume management self-care in patients with chronic heart failure. It will also learn about the intervention's effects on illness perception, self-efficacy, quality of life, emotional status, and clinical outcomes. The main questions it aims to answer are:
* Does the CSM-based intervention improve patients' self-care capacity as measured by the Self-Care of Heart Failure Index (SCHFI)?
* Does the intervention improve patients' illness perception as assessed by the Brief Illness Perception Questionnaire (BIPQ)?
* Does the intervention improve patients' self-efficacy, quality of life, emotional status, cardiac function (LVEF, BNP, heart rate, NYHA class), and dry weight attainment?
* Does the intervention reduce heart failure-related readmission rates and emergency department visits within 3 months post-discharge? Researchers will compare the CSM-based intervention group to a standard care control group. The standard care group receives routine in-hospital education, a health handbook, and regular telephone follow-ups.
Participants in the intervention group will:
* Receive a 5-phase, nurse-led program from hospital admission to 3 months post-discharge
* Attend bedside interviews and structured lectures on volume overload mechanisms during hospitalization
* Complete questionnaires assessing illness perception, self-care, self-efficacy, quality of life, and emotional status at baseline, 1 month, and 3 months
* Receive clinical evaluations including cardiac function tests at baseline and 3 months
* Learn practical skills including daily weight monitoring, sodium restriction, fluid management, and diuretic self-adjustment
* Receive telephone follow-ups weekly in month 1 and biweekly in month 2, with an outpatient visit at month 3
