ASH Clinical Practice Guidelines

ASH develops and publishes evidence-based clinical practice guidelines to help practicing hematologists and other clinicians improve the quality of patient care. ASH’s guideline development is overseen by the ASH Guideline Oversight Subcommittee, which reports to the ASH Committee on Quality. This subcommittee selects guideline topics, vets and appoints individuals to serve on guideline panels, and determines policies and procedures for guideline development.

Browse the existing guidelines below, and learn about guidelines currently in development, including those open for public comment. ASH also endorses other clinical guidelines of relevance to practicing hematologists.

Venous Thromboembolism

A collaboration with the McMaster University GRADE Center, 10 guidelines on the prevention, diagnosis, and treatment of venous thromboembolism.

Von Willebrand Disease

ASH is collaborating with ISTH, NHF, WFH, and the University of Kansas Medical Center to develop two guidelines on the diagnosis and management of von Willebrand disease.

Von Willebrand Disease (VWD)

Guidelines on the Diagnosis and Management of VWD

The American Society of Hematology (ASH), in collaboration with the International Society on Thrombosis and Haemostasis (ISTH), National Hemophilia Foundation (NHF), and World Federation of Hemophilia (WFH), is developing clinical practice guidelines on the diagnosis and management of VWD. Publication of the guidelines is anticipated in 2020.

VWD is a rare disease, but it is one of the most common bleeding disorders in the United States, affecting up to 1 percent of the general population. According to a 2015 report by the NHF, there is variation in clinical practice in both the diagnosis and management of the disease.

Initial Workup of Acute Leukemia

"Initial Diagnostic Work-up of Acute Leukemia: Guideline From the College of American Pathologists and the American Society of Hematology"

On February 22, 2017, the College of American Pathologists (CAP) and the American Society of Hematology (ASH) published an evidence-based guideline that addresses the initial work-up of acute leukemia. The guideline was published in an early online edition of the Archives of Pathology and Laboratory Medicine.

The guideline defines the recommended clinical information and laboratory testing needed for proper diagnosis, with the goal of optimal prognosis of pediatric and adult patients with acute myeloid leukemia (AML), acute lymphocytic leukemia (ALL), and mixed-phenotype acute leukemia (MPAL).

ASH and CAP have provided a mini-review that explains the impetus for the guideline and outlines the recommendations.

The guideline recommendations are also available as a printed pocket guide and in the ASH Pocket Guides app (available on iOS and Android).

Laboratory Workup of Lymphoma

The American Society for Clinical Pathology (ASCP), the College of American Pathologists (CAP), and the American Society of Hematology (ASH) are collaborating to develop a practice guideline on the laboratory workup of patients with suspected lymphoma.

An expert panel formed in 2017 includes both hematopathologists and clinical hematologists representing the three collaborating organizations. The guideline will address laboratory ordering and communications, specimen handling, and diagnostic and prognostic testing including molecular testing.

Acute Myeloid Leukemia

ASH is developing new clinical practice guidelines on the management of acute myeloid leukemia (AML) in older adults. The systematic evidence review and methodological support for these guidelines is being provided by McMaster University. AML affects 61,000 new patients each year. Most of these patients are adults, and the average age of patients in 67 years old.

Publication of the guidelines is expected in 2020.
