The current status of knowledge-attitude-practice and influencing factors of the prevention of lower extremity deep venous thrombosis in patients after traumatic orthopedic surgery

Abstract

Objective To understand the current status of the knowledge-attitude-practice of lower extremity deep venous thrombosis (DVT) prevention in patients after traumatic orthopedic surgery and its influencing factors, and to provide a reference for improving the behavioral intervention strategies. Methods A convenient sampling method was adopted to select 150 orthopedic patients who were hospitalized in the Traumatic Orthopedics Department of a Class A tertiary hospital from January to April 2019. The general demographic data questionnaire and the lower extremity DVT development knowledge-attitude-practice questionnaire were used to collect data. Data analysis was performed using SPSS 18.0 statistical software. Results The total score of knowledge-attitude-practice for DVT prevention in 150 patients was (77.78±8.16) , with knowledge (14.44±4.03) , attitude (54.21±5.34) , and practice (8.09±1.46) . Univariate analysis showed that ages, education levels, occupations, and surgical sites had statistically significant impact on knowledge scores for lower extremity DVT prevention (F=2.075, 14.829, 10.312, 7.406; P<0.05) ; surgical sites had statistically significant impact on attitude scores (F=9.765, P<0.05) ; educational levels, surgical sites and caregivers had statistically significant impact on practice scores (F=3.151, 4.178, 2.810; P<0.05) . Multivariate analysis showed that education levels and occupation were the main influencing factors of knowledge score, and education and primary caregivers were the main influencing factors of practice score. Conclusions The knowledge-attitude-practice of DVT prevention in patients after traumatic orthopedic surgery are affected by education level, occupation and primary caregiver. Patients lack relevant knowledge while having positive prevention attitude, and relatively high behavioral compliance.
