Abstract

Since November 2018, Blood Advances has published American Society of Hematology (ASH) clinical practice guidelines on venous thromboembolism, immune thrombocytopenia, and sickle cell disease. More ASH guidelines on these and other topics are forthcoming. These guidelines have been developed using consistent processes, methods, terminology, and presentation formats. In this article, we describe how patients, clinicians, policymakers, researchers, and others may use ASH guidelines and the many related derivates by describing how to interpret information and how to apply it to clinical decision-making. Also, by exploring how these documents are developed, we aim to clarify their limitations and possible inappropriate usage.

iSoF table. An example of an iSoF table that can be used to explore an intervention’s effect on health outcomes in alternative ways. It includes the question, outcomes, relative and absolute effects, and interpretations (https://gdt.gradepro.org/presentations/#/isof/isof_01618857-BE05-A8CA-8C89-E76E69C5FDD3-1582467465073?_k=w7ov9s).

Example HOD. The purpose of these marker states, or HODs, is to establish common definitions of patient-important outcomes to better inform the guideline panel’s decision-making by including definitions of the consequences for people in terms of symptoms, time horizon, testing and treatment, and consequences (eg, moderate symptomatic proximal DVT) (https://ms.gradepro.org/marker-states/ce16bfaf-cd4d-4138-9c06-1784e3a5413f).
