Summary
We evaluated two clinical scores for the prediction of deep venous thrombosis (DVT)
in hospitalized patients (Wells’ and Kahn’s). We included 273 patients referred to
the vascular exploration unit for the suspicion of DVT. A clinical questionnaire was
filled in by the practitioner and the scores were calculated from this form. 66 of
the 273 patients had a DVT. When Wells’ score was 3, a DVT was found by duplex echography
in 51% patients ; when the score was 0, a DVT was found in 9%. Kahn’s score was not
adapted to this population. We then developed a new simple score (cancer, palsy or
plaster immobilization, warmth, superficial venous dilation, unilateral pitting edema,
other diagnosis). A DVT was found in 76% patients with a score of 3 and in 11% in
those with a score of 0. We therefore propose a 6-item score whose main advantages
are simplicity and usefulness in routine practice.
