The Caprini score is a commonly used risk assessment model for postoperative venous thromboembolism (VTE). It assigns weighted points to patient risk factors and stratifies risk to inform thromboprophylaxis planning.
Formula: Caprini score = age points + (1 x count of 1-point factors) + (2 x count of 2-point factors) + (3 x count of 3-point factors) + (5 x count of 5-point factors).

Higher total scores indicate greater postoperative VTE risk and stronger indication for pharmacologic or extended prophylaxis depending on bleeding risk.
Use Caprini scoring in perioperative planning, especially for inpatient and major surgery pathways where VTE prevention protocols are used.
Risk-factor definitions vary across versions and institutions. Use this calculator with local protocols and formal guideline recommendations.
For related assessments, see Wells Score (DVT), RCRI Score and ASA Class.
