Compliance status and influencing factors of anticoagulation therapy in outpatient undergoing major orthopedic surgery.

Purpose: This study was designed to investigate influencing factors of out-of-hospital anticoagulation therapy compliance among patients undergoing major orthopaedic surgeries. Methods: A cross-sectional, descriptive study was conducted from July 2022 to February 2023 among outpatients who underwent major orthopedic surgery in our hospital. Patients (n = 200) were surveyed using the General Information Questionnaire, the General Self-Efficacy Scale, the Specificity of Medication-Taking Beliefs Scale, and the Morisky Medication Adherence Scale. Factors that influenced patient compliance were also determined using univariate and multivariate regression analyses. Results: One hundred eighty-three valid questionnaires were returned, the compliance with outpatient anticoagulation therapy among patients undergoing major orthopaedic surgeries was good in 56.3% (103/183) of all cases and poor in 43.7% (80/183). Multivariate logistic regression analysis showed that medication duration, adverse effects, self-efficacy and medication beliefs influenced adherence to out-of-hospital anticoagulation therapy in patients undergoing major orthopedic surgery (P < 0.05). Conclusions: Poor compliance with out-of-hospital anticoagulation therapy in patients undergoing major orthopedic surgery is mainly associated with a long course of medication, adverse reactions, low self-efficacy and low medication beliefs. Healthcare staff should strengthen post-discharge anticoagulation management based on relevant influencing factors to enhance patient compliance. [ABSTRACT FROM AUTHOR]
