First, calculate the Wells' Score for DVT (print here), the treatment arms of the protocol are based on the calculated score.
Second, print the DVT Diagnosis and Treatment Protocol here.
Wells Clinical Prediction Rule for DVT
Clinical feature_______________________________ Points
Active cancer (treatment within 6 months, or palliation) 1
Paralysis, paresis, or immobilization of lower extremity 1
Bedridden for more than 3 days because of surgery (within 4 wk) 1
Localized tenderness along distribution of deep veins 1
Entire leg swollen 1
Unilateral calf swelling > 3 cm (below tibial tuberosity) 1
Unilateral pitting edema 1
Collateral superficial veins 1
Alternative diagnosis as likely as or more likely than DVT -2
Total points: ..........
Risk score interpretation (probability of DVT):
>=3 points: high risk (75%);
1 to 2 points: moderate risk (17%);
<1 point: low risk (3%)
