Scientific titleNOSTRADAMUS: testing for thrombophilia in patients with a first episode of venous thromboembolism: a randomised controlled trial to assess effects on clinical outcomes, quality of life, and costs
Study acronymNOSTRADAMUS
Study objectivesTesting for thrombophilia after a first episode of Venous ThromboEmbolism (VTE) with subsequent prolongation of anticoagulant treatment in thrombophilic patients is beneficial in terms of clinical outcomes, quality of life, and costs.
Ethics approval(s)Approval received from the Medical Ethics Board of the Acamdemic Medical Center Amsterdam on September 20th 2006 (ref: MEC 06/216).
Health condition(s) or problem(s) studiedPulmonary embolism, deep vein thrombosis
InterventionRandomisation between disclosure and undisclosure of results of thrombophilia screening and subsequent additional anticoagulant treatment for a predefined period will be installed in those in whom thrombophilia is detected in the disclosure group.
Intervention typeOther
Primary outcome measureRecurrent VTE 18 months after the acute episode of VTE.
Secondary outcome measures1. Recurrent VTE at the end of the study
2. A composite endpoint of recurrent VTE and bleeding at the end of the study
3. Quality of life
4. Costs of testing and subsequent predefined prolongation of anticoagulant therapy
