The Ideal Deep Venous Thrombosis (DVT) Study

In the Netherlands, 25.000 patients each year are diagnosed with Deep Venous Thrombosis (DVT). Elastic compression stocking (ECS) therapy reduces the incidence of post thrombotic syndrome (PTS) following DVT from 50% without ECS to 20-30% after ECS therapy for two years. It is however unclear whether all patients benefit to the same extent from this therapy or what the optimal duration of ECS therapy for individual patients should be. ECS therapy is not only costly, inconvenient and demanding but sometimes also even debilitating. Substantial costs could be saved by tailoring therapy to individual needs and as a result the quality of life for individual patients can be expected to improve.

This study aims to assess the costs and effects of tailoring the duration of ECS therapy after DVT to individual patients needs.

ECS therapy with a standard duration of 24 months will be compared with tailored ECS therapy, following an initial therapeutic period of 6 months, in patients with acute proximal DVT. The primary outcome is the percentage of patients with PTS at two year follow-up.

This is a multi-center, randomized, allocation concealed, single-blinded clinical trial.

  • Acute objectively documented DVT of the leg
  • Adequate anticoagulation

Exclusion criteria

  • Previous DVT in the affected leg
  • Recurrent DVT in the first 6 months following inclusion

Treatment and study plan

Individually tailored duration of elastic compression therapy

Device

Individually tailored duration of elastic compression therapy,based on signs and symptoms according to the Villalta scale, following an initial therapeutic period of 6 months

Other names: Custom made flat knitted, knee length, class III stockings (Mediven ®550, ankle pressure 40 mmHg)

Elastic compression therapy with a standard duration of 24 months

Device

Elastic compression therapy with a standard duration of 24 months

Other names: Custom made flat knitted, knee length, class III stockings (Mediven ®550, ankle pressure 40 mmHg)

Primary outcomes

  1. The occurrence of PTS at 24 months after the event of acute DVT

    Time frame: At 24 months after the event of the acute DVT

Secondary outcomes

  1. Health Related Quality of Life (HRQOL)

    Time frame: Baseline, 3, 6, 12 and 24 months

    HRQOL, will be measured by questionnaires SF-36, EuroQol-5D, Veines-Qol Dutch translated

  2. Recurrent venous thrombosis

    Time frame: 24 months

  3. Mortality due to venous thrombosis

    Time frame: 24 months

  4. Costs

    Time frame: 3, 6, 12, 24 months

    Costs will include direct costs (e.g. medical therapy) and indirect costs (e.g. travel) and will be measured by case record forms, hospital data and 5 retrospective cost-questionnaires

  5. Patient Preferences

    Time frame: baseline, 24 months

    Patient preferences will be elicited by conducting a discrete choice experiment (DCE)
