Revaluation of Wells' Clinical Prediction Score of Deep Vein Thrombosis (DVT) 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.

Inclusion criteria

  • Any patient addressed to an Vascular Medicine unit for a clinical suspicion of DVT, with risk stratification through the modified Wells score by the referent doctor.

Exclusion criteria

  • Patient addressed to our Vascular Medicine unit for any other reason.
  • Patient addressed to our Vascular Medicine unit for DVT detection to help in a pulmonary embolism suspicion.
  • Age under 18 yo
  • Patients unable to express their informed consent.

Treatment and study plan

Doppler Ultrasound

Diagnostic Test

Each patient received Doppler ultrasound for research of DVT, no matter the risk stratification.

Primary outcomes

  1. Performance of the Wells Clinical prediction score

    Time frame: For enrollment to end of enrollment at 12 months

    Analyse area under the curve (AUC) of the Wells' score ROC (Receiver Operating Characteristic) curve for an inpatient population

Secondary outcomes

  1. Impact of thromboprophylaxis treatment

    Time frame: For enrollment to end of enrollment at 12 months

    Compare area under curve of ROC curves of Wells' score between an inpatient population with or without thromboprophylaxis treatment

  2. Coherency of Wells' score between an doctor specialized in thrombosis and any other doctor.

    Time frame: For enrollment to end of enrollment at 12 months

    Compare Area under curve for ROC curves of Wells' score between an doctor specialized in thrombosis and any other doctor.
