Objective: To study the effect of combined application of Information-Knowledge-Belief-Behavior (IKAP) theory continuity care on patients undergoing cerebrovascular interventional surgery based on bundle care.\nMethods: A retrospective analysis was conducted on the clinical data of 88 patients who underwent cerebrovascular interventional surgery for cerebrovascular diseases at our hospital from April 2022 to April 2024. According to the nursing interventions they received, the patients were divided into a control group (n=44, receiving bundle care intervention) and an observation group (n=44, receiving combined bundle care and IKAP theory continuity care). The knowledge of disease, psychological resilience [Connor-Davidson Resilience Scale (CD-RISC)], activities of daily living [Barthel Index (BI)], sleep quality [Pittsburgh Sleep Quality Index (PSQI)], self-management [Cerebrovascular Disease Self-Management Scale], and satisfaction [Newcastle Satisfaction with Nursing Services Scale (NSNS)] were compared between the two groups.\nResults: (1) Knowledge of Disease: The disease knowledge awareness rate in the observation group (93.18%) was significantly higher than that in the control group (77.27%) (P<0.05). (2) Psychological Resilience: After intervention, the resilience scores, self-empowerment scores, and optimism scores of both groups increased compared with pre-intervention, with a greater increase observed in the observation group (P<0.05). (3) Activities of Daily Living and Sleep Quality: After intervention, the BI index in both groups increased, and the PSQI score decreased compared with pre-intervention, with a greater change observed in the observation group (P<0.05). (4) Self-Management: After intervention, the scores for disease monitoring, medication management, rehabilitation exercise, diet management, and emotional management in both groups increased compared with pre-intervention, with a greater improvement in the observation group (P<0.05). (5) Satisfaction: The satisfaction rate in the observation group (90.91%) was significantly higher than that in the control group (70.45%) (P<0.05).\nConclusion: The combined application of IKAP theory continuity care based on bundle care can further improve patients\' disease knowledge awareness and self-management ability, enhance psychological resilience, activities of daily living, and sleep quality, and increase the satisfaction and recognition of patients and their families.
