What this trial studies

This observational study aims to develop a comprehensive and reliable risk prevention system for venous thromboembolism (VTE) during the perioperative period by utilizing medical big data and a multi-module computer approach. VTE, which includes deep vein thrombosis (DVT) and pulmonary thromboembolism (PTE), is a significant cause of postoperative complications and mortality. The study will assess perioperative patients aged 10 to 90 years, gathering data to improve risk assessment and prevention strategies. By enhancing the existing Caprini scale, the study seeks to adapt to modern surgical practices and patient profiles.

Why it matters

Potential benefit: If successful, this system could significantly reduce the incidence of VTE and related mortality in perioperative patients.

How similar studies have gone: Previous studies have shown success in using risk assessment scales like the Caprini scale, but this approach aims to innovate and adapt to current clinical practices.
