The IMPROVE score for [[venous thromboembolism]] (VTE) assesses the risk of VTE among hospitalized medical patients. The IMPROVE predictive score for VTE includes 4 independent risk factors for VTE which are present at admission.

Overview
The IMPROVE score for venous thromboembolism (VTE) assesses the risk of VTE among hospitalized medical patients. The IMPROVE 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 Predictive Score for VTE
Calculation of the IMPROVE Predictive Score
Variable | Score[1] |
Prior episode of VTE | 3 |
Thrombophilia | 3 |
Malignancy | 1 |
Age more than 60 years | 1 |
Interpretation of the IMPROVE Predictive Score
Score | Predicted VTE risk through 3 months[1] |
0 | 0.5% |
1 | 1.0% |
2 | 1.7% |
3 | 3.1% |
4 | 5.4% |
5-8 | 11% |
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]
Calculation of the IMPROVE Associative Score
Variable | Score[1] |
Prior episode of VTE | 3 |
Thrombophilia | 2 |
Paralysis of the lower extremity during the hospitalization | 2 |
Current malignancy | 2 |
Immobilization for at least 7 days | 1 |
ICU or CCU admission | 1 |
Age more than 60 years | 1 |
Interpretation of the IMPROVE Associative Score
Score | Predicted VTE risk through 3 months[1] |
0 | 0.4% |
1 | 0.6% |
2 | 1.0% |
3 | 1.7% |
4 | 2.9% |
5-10 | 7.2% |
IMPROVE-DD score for VTE risk stratification
IMPROVEDD VTE 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]
