Objective To explore the best evidence-based non-pharmacological prevention method of perioperative deep vein thrombosis(DVT)in patients with brain tumor,and to evaluate its application effect.Methods Guided by the"Evidence-Based Continuous Quality Improvement Model",evidence-based practice was applied to perioperative patients with brain tumors according to 4 stages of evidence acquisition,status review,evidence introduction,and effect evaluation from April to September 2021.The changes in the incidence of DVT and other indicators of patients before and after the application of evidence-based practice were compared.Results A total of 19 evidence for non-pharmacological prevention of perioperative venous thrombosis were summarized and transformed into 34 review in-dicators for evidence-based practice.The implementation rate of review indicators for prevention of DVT during peri-operative period of brain tumor and nurses DVT-related knowledge,attitude,and behavior levels were significantly improved,and the differences in knowledge and behavior dimensions were statistically significant(both P＜0.05).The incidence of DVT decreased from 10.75％to 4.05％(P=0.020),and the patient knowledge score increased from(14.00±2.14)points to(22.00±2.87)points(P＜0.001).Conclusion The evidence-based practice of non-pharmacological prevention of perioperative DVT in patients with brain neoplasms,clinical environment can effec-tively improve the clinical practice environment,cultivate the evidence-based concept of nurses,and improve their knowledges,attitudes,and compliances with clinical measures,promote patients'prevention knowledge level,and reduce the incidence of clinical DVT.
