IMPROVEDD VTE risk score

Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]

Overview

The IMPROVEDD risk score, which adds D-dimer to the conventional IMPROVE score, improves the prediction of venous thromboembolism events in acutely ill patients within 42 days of hospitalization compared to the IMPROVE score.Gibson, CM (2017).

Thrombosis Haemostasis. 1 (1): 56–65. doi:10.1055/s-0037-1603929.
