Overview

The IMPROVE score for venous thromboembolism (VTE) assesses the risk of VTE among hospitalized medical patients. The MPROVE predictive score for VTE includes 4 independent risk factors for VTE which are present at admission. The IMPROVE associative score for VTE includes 7 variables present either at admission or during hospitalization; however the timing of the presence of some of the factors compared to the onset of VTE was not available.^[1]

IMPROVE Associative Score for VTE

IMPROVE associative risk score assesses the risk of VTE among hospitalized medical patients. While the IMPROVE predictive score includes 4 independent risk factors for VTE which are present at admission, IMPROVE associative score includes 7 variables present either at admission or during hospitalization; however the timing of the presence of some of the factors compared to the onset of VTE is not available.^[1]
