Knowledge, attitude, and practice toward postoperative self‐management among patients after percutaneous coronary intervention: A structural equation modeling analysis

Abstract

AbstractObjectiveThe knowledge, attitude, and practice (KAP) toward post‐percutaneous coronary intervention (PCI) self‐management among Chinese patients remains unknown. This study investigated the KAP toward postoperative self‐management among patients after PCI.HypothesisPatients exhibit poor knowledge, attitudes, and practices regarding post‐PCI self‐management, requiring enhanced education strategies.MethodsThis cross‐sectional study recruited patients after PCI at Jishuitan Hospital, Beijing, between November 2022 and May 2023. Inclusion criteria comprised patients 1–3 months post‐PCI, those capable of self‐care, and those willingly participating. The questionnaire (49 items) was designed with reference to current guidelines (the Cronbach α = .829). The final questionnaire included four dimensions with 49 items. The Pearson correlation analysis and structural equation modeling (SEM) were used to determine the relationship among knowledge, attitude, and practice.ResultsA total of 476 valid questionnaires were included. The knowledge, attitude, and practice scores were 8.24 ± 2.78 (possible range: 0–12), 21.61 ± 3.15 (possible range: 9–45), and 32.62 ± 3.75 (possible range: 10–50). The Pearson correlation analysis showed only knowledge scores were correlated with the attitude scores (r = .446, p < .001). The SEM showed that knowledge directly affects attitude (β = .616, p < .001) but had no influence on practice (β = .119, p = .155); attitude had no influence on practice (β = .015, p = .809).ConclusionThis study indicated that patients had poor knowledge, unfavorable attitudes, and unsatisfied practice toward post‐PCI self‐management. Strengthening patient health education through diverse approaches is imperative.
