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% |
