The association between surgical duration and venous thromboembolism in outpatient surgery: A propensity score adjusted prospective cohort study

摘要

Outpatient surgeries account for 60–70% of all procedures. Increased surgical duration has been demonstrated to be an independent risk factor for the development of venous thromboembolism (VTEs) after inpatient surgeries. In contrast, it is currently unknown if surgical duration increases the risk of VTEs for outpatient surgeries.
