Insights
Anticoagulation clinics rarely prescribe compression stockings for deep vein thrombosis (DVT) patients, despite guidelines recommending them for preventing post-thrombotic syndrome (PTS). Increased clinic responsibility could improve stocking use and adherence.
Area of Science:
- Vascular Medicine
- Clinical Pharmacy
- Thrombosis Management
Background:
- Anticoagulation clinics manage oral anticoagulant therapy for venous thromboembolic disease (VTE).
- These clinics are well-positioned to manage other long-term VTE aspects, including post-thrombotic syndrome (PTS) prevention.
- Current guidelines recommend graduated elastic compression stockings for 2 years post-deep vein thrombosis (DVT) to prevent PTS.
Purpose of the Study:
- To assess the current use of compression stockings in DVT patients managed by anticoagulation clinics.
- To determine adherence to recommended compression strength and duration.
- To explore expanding the scope of practice for anticoagulation clinics in VTE long-term management.
Main Methods:
- A survey was distributed to healthcare providers in anticoagulation clinics.
- The survey collected data on the prescription of compression stockings for DVT patients.
- Data included who prescribed the stockings, compression strength, and duration of therapy.
Main Results:
- A very low rate of compression stocking prescription for DVT patients was observed.
- Adherence to current guidelines regarding compression strength and duration was limited.
- Significant gaps exist between guideline recommendations and current clinical practice.
Conclusions:
- Anticoagulation clinics currently have low rates of prescribing compression stockings for DVT.
- There is a need to improve adherence to guidelines for compression stocking use in DVT patients.
- Expanding the scope of anticoagulation clinics to include comprehensive antithrombosis care, including PTS prevention, is recommended.
Abstract:
Anticoagulation clinics are increasingly used to manage oral anticoagulant therapy in patients with venous thromboembolic disease (VTE). Such clinics may be in a position to assume greater responsibility for other aspects of the long-term management of VTE, including prevention of post-thrombotic syndrome (PTS). Current guidelines suggest use of graduated elastic compression stockings with a pressure of 30-40 mm Hg at the ankle for 2 years following the diagnosis of deep vein thrombosis (DVT) to prevent PTS. A survey of anticoagulation clinic providers was conducted to determine to what extent patients with DVT are prescribed compression stockings and by whom, and the degree of compression and duration of therapy prescribed. Survey results show a very low rate of use of compression stockings in patients with DVT, and limited adherence to current recommendations for strength and duration of use. We believe that healthcare providers practicing in anticoagulation clinics should be encouraged to expand their scope of practice into a more comprehensive model of antithrombosis care, including prevention of PTS. By doing so, the extent of use of compression stockings might be increased, and adherence to current guidelines for strength and duration of compression might be improved.
