Patient Survey about Blood Thinner Preferences

| Comments Off

Stephan Moll, MD writes…  A research study is being conducted at the University of Minnesota by Dr. Pamela Lutsey.  The goal of the study is to learn more about patients’ concerns and preferences regarding blood thinner use for the treatment of DVT and PE.  The results will help investigators better create future clinical studies to improve  treatment of DVT and PE.  This is NOT a pharmaceutical industry or marketing survey.  If you are a patient who has had a DVT or PE it would be great if you were willing to take the short survey.  It will take about 10 minutes to complete.  Thank you very much.  The following link will direct you to the secure survey site: z.umn.edu/vtesurvey.

New Guideline for treatment of DVT and PE

| Comments Off

The ACCP Chest Guidelines have been the main guide over the last more than 2 decades for evidence-based recommendations on best management of blood thinners for various indications, including DVT and PE.  The 10th edition of the chapter on DVT and PE management was published today – link here.

30 Recommendations

This 38 page document focusses on the best management of DVT and PE.  It provides 30 individual recommendations (page 7-19) and a discussion of the evidence behind the guidance.  It uses the terms “suggest” and “recommend” for its guidance, depending on the strength of published evidence.

Key Recommendations

  • Choice of blood thinner
    In patients with DVT of the leg or PE (and no cancer) the suggestion is to use one of the newer oral blood thinners (Eliquis, Pradaxa, Savaysa or Xarelto) rather than warfarin (Coumadin, Jantoven) therapy!
  • Cancer patients with DVT or PE: 
    In cancer patients with DVT of the leg or PE an injectable blood thinner called “low molecular weight heparin” (Lovenox = enoxaparin; Fragmin = dalteparin; Innohep = tinzaparin) is suggested rather than an oral drug.
  • How long to treat with blood thinners?
    • DVT (in veins in the pelvis, thigh or behind the knee, termed “proximal DVT) or PE provoked by surgery:  recommend 3 months of blood thinners.
    • Proximal DVT or PE  provoked by non-surgical transient risk factor (e.g. estrogens, pregnancy, leg injury, flight > 8 hrs): suggest 3 months of blood thinners.
    • Unprovoked proximal DVT or PE: suggest long-term blood thinners.
    • Distal DVT, i.e. below the knee
      • if not severely  symptomatic : suggest no blood thinners, but follow-up Doppler ultrasound imaging study
      • if severely symptomatic: suggest 3 months of blood thinners.
  • Role of aspirin:
    In patients with unprovoked proximal DVT or PE who stop blood thinners, aspirin is suggested.

Personal comment

This is a solid guideline and good publication.

Patient Volunteers Needed for Guideline Development

| Comments Off

Stephan Moll, MD writes…  The American Society of Hematology (ASH) is embarking on a program to develop clinically useful guidelines on the best management of patients with deep vein thrombosis or pulmonary embolism.  ASH appropriately desires input from patients for the development of these guidelines.  Any interested patient please see this letter from ASH explaining the goals of the project and what is needed.
