What this is
Score two complementary venous-thromboembolism tools side by side. Wells DVT is a 9-item pretest probability score for an acutely symptomatic leg (active cancer, paralysis or recent cast, recent bed rest or major surgery, localized tenderness, leg swelling, calf-circumference difference, pitting edema, collateral veins, alternative diagnosis at least as likely) that stratifies a patient as DVT likely or unlikely. Caprini is a longer inpatient/perioperative risk-assessment model that totals risk factors to predict 30-day VTE risk and guide prophylaxis intensity. Sophie Well computes both from a single inputs panel.
When to use it
Use Wells DVT in the ED or clinic when an acutely symptomatic leg raises concern for deep vein thrombosis - the score gates whether a D-dimer can rule out the diagnosis or whether ultrasound is needed up front. Use Caprini on admission or before a surgical procedure to choose between mechanical, chemical, or combined prophylaxis. The two scores answer different questions on different timelines; running them together is most useful when an admitted surgical patient develops new leg symptoms and you need both the acute workup and the next prophylaxis decision in one place.
