ASH Clinical Practice Guidelines on Venous Thromboembolism

VTE_Video_ThumbnailClick image for video of experts discussing the new guidelines.

In 2014, in response to long-standing member interest, ASH initiated an effort to develop evidence-based clinical practice guidelines for hematology that meet the highest standards of development, rigor and trustworthiness. Development of these guidelines, including systematic evidence review, was supported by the McMaster University GRADE Centre, a world leader in guideline development. With their partnership, ASH brought together ten panels of more than 100 thrombosis experts to review evidence and formulate more than 200 recommendations on venous thromboembolism (VTE).

Available Guidelines:

Coming Soon:

  • Treatment
  • Cancer
  • Thrombophilia

The ASH VTE guidelines have been endorsed by the following organizations:

  • American Association of Hip and Knee Surgeons (AAHKS)
  • Anticoagulation Forum (AC Forum)
  • Eastern Association for the Surgery of Trauma (EAST)
  • Foundation for Women & Girls with Blood Disorders (FWGBD)
  • International Society on Thrombosis and Haemostasis (ISTH)
