  • Caprini Score: Explanation and Clinical Context
    The Caprini Risk Assessment Model (2010 update) provides a detailed and validated scoring system to estimate venous thromboembolism (VTE) risk in surgical patients. Each risk factor is assigned a weight of 1, 2, 3, or 5 points based on its relative contribution to VTE development.
    Total scores classify patients into risk categories: Very Low, Low, Moderate, High, Very High, and Highest risk, guiding clinicians in the appropriate use of mechanical and pharmacologic prophylaxis.
    This precise version improves predictive accuracy, allowing more individualized and evidence-based VTE prevention strategies in surgical populations.
