Abstract
Purpose
To assess hospitalized patients' knowledge, attitudes, and practices (KAP) regarding deep venous thrombosis (DVT) causes and prevention.Patients and methods
A cross-sectional survey was conducted at the Second Affiliated Hospital of Chongqing Medical University between March 1 and May 30, 2024. Self-developed questionnaires were used to collect demographic data and KAP from hospitalized patients. Multivariable logistic regression and structural equation modeling (SEM) were utilized to evaluate associated factors and mediating pathways. KAP scores were categorized into three levels: good (>75% of the range; K: >12; A, P: >40), moderate (50-75% of the range; K: 8-12; A:30-40, P: 30-40), and poor (≤50% of the range; K: ≤8; A:30-40, P: ≤30).Results
A total of 567 valid questionnaires were analyzed. Most patients had not received relevant education on DVT (68.6%). The mean (SD) scores were 5.88 (2.32) for knowledge, 40.06 (7.18) for attitude, and 32.53 (9.22) for practice. Many participants were uncertain about DVT's definition, etiology, symptoms, and preventive measures (31.0% to 54.0%). Eighty-four percent believed DVT prevention requires cooperation between medical staff, patients, and families. Eighty-one percent preferred oral anticoagulants. Thirty-seven percent monitored DVT symptoms regularly, and thirty-three percent learned about DVT from medical staff. Multivariate analysis showed that knowledge (OR=1.293, P<0.001) and attitude (OR=1.031, P=0.046) were protective factors positively associated with practice. Smoking (OR=0.601, P=0.026), no history of thrombosis (OR=0.292, P=0.003), and lack of education (OR=0.448, P=0.007) were independently associated with non-adherence, acting as independent risk factors for poor preventive practices. SEM results showed direct (β= (0.306, P=<0.001) and indirect effects of knowledge on practice (β=0.073, P=0.007).Conclusion
Hospitalized patients showed poor knowledge, positive attitudes, and moderate practices towards DVT. Targeted educational interventions are needed to improve their KAP regarding DVT.
