AMUSE Score Calculator

Calculation of the AMUSE Score

The AMUSE score includes clinical variables in addition to the results of a qualitative D-dimer test to evaluate the need to proceed with ultrasonography among patients with suspected DVT. The study of the AMUSE score was designed for the primary care setting.

Check all boxes that apply to your patient:

Interpretation of the AMUSE Score

The interpretation of the score is as follows:

• Score ≤3: Not high suspicion of DVT: Should not proceed with ultrasonography
• Score ≥4: High suspicion of DVT: Should proceed with ultrasonography
