The study aims to evaluate the incidence and timing of postoperative venous thromboembolism across various surgical specialties.
Analyzed data from the 2022 ACS-NSQIP for adult patients (≥18 years) across several surgical specialties.
Outcomes assessed include incidence rates and timing of VTE diagnosis after surgery.
Focused on patients undergoing general surgery, colorectal, vascular, plastic surgery, surgical oncology, and gynecology.
0.8% of 525,726 patients developed VTE within 30 days, highest in surgical oncology (3%) and colorectal surgery (2%).
Median time to VTE diagnosis was 9 days; 54% diagnosed after discharge, with plastic surgery having 77% diagnosed post-discharge.
Surgical oncology and colorectal surgery had the highest odds of VTE development, but lower post-discharge diagnosis rates.

Randomized trial evaluates postoperative VTE incidence in surgical patients, suggesting specialty-specific surveillance is essential.
