Application of the Cox Health Behavior Interactive Nursing Model in Blood Purification Patients with Chronic Renal Failure and Its Impact on Self-Management Ability

Objective: To observe the application of the Cox healthy behavior interactive nursing model in patients with chronic renal failure and blood purification and its impact on their self-management ability. Methods: 82 patients with chronic renal failure and blood purification in our hospital (from January 2025 to December 2025) were randomly divided into a control group (41 cases) of routine care and an observation group (41 cases) of the Cox healthy behavior interactive care model. Results: Compared with the control group, the observation group had higher self-management ability scores, lower complication rates, higher satisfaction scores, and higher quality of life scores, P < 0.05. Conclusion: The Cox healthy behavior interactive nursing model for blood purification patients with chronic renal failure can improve patients' self-management ability, reduce the incidence of complications, alleviate negative emotions, and promote the improvement of quality of life, which is worth learning from.
