This study evaluates the effectiveness of a continuous comprehensive nursing (CCN) system compared to routine care for patients after coronary artery bypass graft (CABG) surgery. The primary goal is to determine if the CCN system improves postoperative hemoglobin levels. The study also investigates the effects on quality of life, mental health (anxiety and depression), red blood cell indices, immune markers, and patient satisfaction.
Coronary artery bypass surgery (CABG) is a major procedure, and the postoperative recovery process is complex, often impacting patients' hemoglobin levels and quality of life. Standard nursing care is often limited to the inpatient period. A continuous comprehensive nursing (CCN) system is a holistic, patient-centered model that extends care beyond hospital discharge. This model includes preoperative education, continuous monitoring, personalized care plans, psychological support, rehabilitation guidance, and structured follow-up. While the benefits of comprehensive nursing are recognized, its specific impact on hemoglobin recovery and quality of life after CABG has not been extensively studied. This randomized controlled trial was designed to compare the outcomes of patients receiving a CCN plan with those receiving routine postoperative care to provide evidence for optimizing post-CABG nursing strategies.

A multi-faceted nursing plan delivered by trained cardiac nurses, extending from the preoperative phase to 3 months post-discharge. In addition to routine inpatient care, the intervention included: preoperative education and psychological support; postoperative individualized rehabilitation guidance; and a continuous post-discharge program. The post-discharge phase involved structured follow-up (monthly phone calls, one 6-week outpatient visit), ongoing psychological support, reinforcement of education on medication adherence, diet, and activity progression, and guidance on a structured home-based exercise program.
Standard institutional postoperative care for patients after Coronary Artery Bypass Graft (CABG) surgery. This care was primarily focused on the inpatient period and included monitoring of vital signs, wound and drainage tube management, respiratory and circulatory support, and progressive diet guidance. The care concluded with standard discharge instructions and did not include the structured, continuous, or extended follow-up provided to the intervention group.

Change in Hemoglobin (Hb) Levels from Baseline to Day 7 Post-Surgery
The change in hemoglobin concentration (g/L) was measured from the preoperative baseline value to the value at 7 days after the surgery. Venous blood samples were analyzed using an automatic biochemical analyzer.
Time frame: Baseline (preoperatively) and Day 7 post-surgery.
Change in Hemoglobin (Hb) Levels at Other Time Points
Hemoglobin concentration (g/L) measured at multiple time points to assess the recovery trajectory.
Time frame: Baseline, 12 hours, 72 hours, and 14 days post-surgery.
Red Blood Cell Indices
Measurement of Mean Corpuscular Volume (MCV, in fL), Red Blood Cell Distribution Width (RDW, in %), and Hematocrit (HCT, in %).
Time frame: Day 7 post-surgery.
Levels of Immune-Related Inflammatory Markers
Levels of Interleukin-2 (IL-2, in pg/mL) and Interleukin-6 (IL-6, in pg/mL) in peripheral blood, quantified using an ELISA kit.
Time frame: Day 7 post-surgery.
Quality of Life (QoL)
Assessed using the World Health Organization Quality of Life BREF (WHOQOL-BREF) scale. This scale evaluates four domains: physical health, psychological health, social relationships, and environment. Higher scores indicate better quality of life.
Time frame: Day 14 post-surgery.
Depressive Symptoms
Assessed using the Center for Epidemiologic Studies Depression Scale (CES-D). The scale ranges from 0 to 60, with higher scores indicating more severe depressive symptoms.
Time frame: Day 14 post-surgery.

Anxiety Symptoms
Assessed using the Self-Rating Anxiety Scale (SAS). The scale ranges from 20 to 80, with higher scores reflecting more severe anxiety symptoms.
Time frame: Day 14 post-surgery.
Patient Satisfaction
Assessed using a study-specific satisfaction questionnaire. Responses were categorized as "very satisfied," "satisfied," "average," or "dissatisfied" based on a scoring system from 1-100.
Time frame: Up to 14 days post-surgery (at time of hospital discharge).
