Study Overview
Brief Summary
Venous thromboembolism (VTE) is a frequent multifactorial and potential life-threatening disease. Once VTE has been diagnosed, anticoagulation should be started and prolonged for at least three to six months in order to reduce the risk of fatal and non-fatal recurrences and long-term sequelae. The development of direct oral anticoagulants (DOACs) has represented a major advance in patients' care as there is evidence that DOACs are associated with a decreased risk of bleeding without loss in efficacy and as it simplifies treatment modalities for the patients and the physician. However, as DOACs do not require laboratory monitoring, adherence of anticoagulation is difficult to evaluate and traditional programs built on patients receiving VKA may no longer be applicable to patients on DOAC. In order to increase treatment adherence in patients on DOAC for an acute VTE and to improve the quality of life, the impact of specific educational programs on DOACs, taking in account both therapeutic (DOAC) and medical illness (VTE) dimensions needs to be investigated.
In patients with an acute episode of VTE treated for at least 6 months, the main hypothesis is that early debriefing and educative components added to a standardized visit one month after an acute VTE has the potential to improve patient's adherence to APIXABAN therapy at 6 months of follow-up.

Design The "DEBRIEF-VTE" trial is a multicenter randomized trial with blind evaluation and using a Zelen randomization process comparing a standardized follow-up visit at one month associated with a "debriefing and enhanced educative components" versus a standardized follow-up visit at one month alone (i.e.; without debriefing process).
All patients meeting the inclusion and none of the exclusion criteria are eligible for randomization. They will be randomized 1:1 to one of two allocated groups:
-
Experimental group: a standardized follow-up visit at one month associated with "debriefing and enhanced educative component"
-
Control group: a standardized follow-up visit at one month alone (i.e.; without "debriefing and educative component") Randomization will be performed using a two-step methodology described by Zelen et al.
-
Stratification by:
-
Center
-
DVT or PE
-
Presence of a major risk factor (either transient or persistent) or not (unprovoked VTE) At visit 1 (inclusion, 0-7 days): Inclusion of patients using the first written informed consent to accept a standard follow-up (visit at 1 month and 6 months) without mentioning randomization at one month performed in order to allocate patients to have, or to not have, debriefing and enhanced educative components. Study medication will be administered with complete explanation about doses and a classical therapeutic information regarding DOAC and clinical signs of recurrent VTE and bleeding (one treatment box with 400 pills of apixaban at 5 mg for the first 6 months of therapy) will be performed.

Outcomes
Primary Outcomes
Treatment adherence mesured by Medication Event Monitoring System Cap
Time Frame: at 6 months
Adherence to apixaban therapy at 6 months after an acute episode of VTE measured by the MEMSCap™ will be evaluated. The main criteria for adherence measurement will be the number of days where patients took adequately apixaban divided by the number of expected days of prescription. An additional evaluation will be the number of taken pills divided by the expected taken pills.
Secondary Outcomes
- Mortality(during a study treatment period of 6 months)
- Hospitalisation for an acute medical illness during treatment period will be evaluated by questioning the patient(during a study treatment period of 6 months)
- Treatment adherence mesured by Medication Event Monitoring System Cap(at 1 month and 3 months)
- Recurrent VTE (Symptomatic recurrent pulmonary embolism and Symptomatic recurrent deep-vein thrombosis) diagnosed on the basis of a clinical suspicion(during a study treatment period of 6 months)
- Major and clinically relevant non major bleeding(during a study treatment period of 6 months)
- Quality of life after an acute VTE(At 6 months)
