Study summary

Venous thromboembolism (VTE) is a highly preventable but potentially fatal complication following gynecological surgery. The Caprini risk assessment model is widely used, but real-world evidence evaluating the net clinical benefit and cost-effectiveness of different prophylaxis strategies (mechanical vs. pharmacological) in gynecological patients with Caprini score $\\ge$ 2 is still lacking. This study aims to evaluate the relative effectiveness of basic, mechanical, and pharmacological VTE prophylaxis strategies using a retrospective 1:3 matched nested case-control design. Furthermore, a decision tree model will be constructed to evaluate the incremental cost-effectiveness ratio (ICER) of these strategies to provide health economic evidence for optimizing VTE management pathways in gynecology
