This study is a quasi-experimental study designed to evaluate the effects of a health coaching intervention on self-management ability in patients undergoing maintenance hemodialysis. Patients receiving maintenance hemodialysis will be recruited from the hemodialysis center of the study hospital. Participants in the intervention group will receive a structured health coaching intervention in addition to routine care, while participants in the control group will receive routine care. The intervention aims to improve patients' self-management ability by providing individualized health education, goal setting, self-management guidance, follow-up support, and feedback. The main outcome of this study is self-management ability. Secondary outcomes may include self-efficacy, disease knowledge, and treatment adherence.
