Revaluation of Wells' Clinical Prediction Score of Deep Vein Thrombosis (DVT) in Inpatients With Thromboprophylaxis Treatment (R-WITT)

November 24, 2025 updated by: Centre Hospitalier Universitaire de Nīmes

R-WITT Study : Revaluation of Wells' Clinical Prediction Score in Inpatients With Thromboprophylaxis Treatment

This study aimed (1) revaluating the efficacy of the Wells' clinical prediction score for an inpatient population; and the weight of the presence of thromboprophylaxis treatment on the score, and (2) evaluating the correlation of a risk stratification established between a physician specialised in thrombosis and any other doctor.
