Analysis of the Current Status and Influencing Factors of Knowledge, Beliefs, and Behaviors Regarding Deep Vein Thrombosis Prevention in Postoperative Patients Among Nursing Students

Objective: To investigate nursing students' knowledge, beliefs, and behaviors (KBB) regarding deep vein thrombosis (DVT) prevention in postoperative patients and analyze influencing factors. Methods: A cross-sectional survey was conducted via a general information questionnaire and the Chinese version of the DVT Prevention KBB Questionnaire. Data were analyzed with SPSS 27.0, including descriptive statistics, Mann-Whitney U (M-W U) test, Kruskal-Wallis H (K-W H) test, and multiple linear regression analysis (MLRA). Results: Nursing students' DVT prevention knowledge, belief, and behavior scores were (11.35 ± 2.23), (37.86 ± 9.00), and (53.68 ± 13.99) points, respectively. MLRA showed gender and prior DVT knowledge learning influenced knowledge scores; gender, prior DVT knowledge learning, and surgical internship experience affected belief scores; gender and prior DVT knowledge learning impacted behavior scores. Conclusion: Intern nurses had moderate DVT prevention KBB, influenced by modifiable factors. Systematic training integrating theory and practice, and optimized clinical teaching strategies are needed to improve their DVT prevention capabilities.
