Practice Guidelines

AASLD’s practice guidelines provide evidence-based recommendations and outline appropriate methods of treatment and care for clinicians. The guidelines are developed by multidisciplinary panels of experts who rate the quality (level) of the evidence and strength of each recommendation using the Grading of Recommendations Assessment, Development, and Evaluation system or, in some unique cases, Oxford Levels of Evidence Grading. Patient representation is an important component in the development of clinical practice guidelines and is a priority for inclusion in future guideline panels.

Historically, AASLD has developed practice guidances which are put forward to help clinicians understand and implement the most recent evidence based on comprehensive review and analysis of the literature. Recently AASLD has published guidances on aspects of a topic that lacked sufficient data to perform systematic reviews or rate the quality (level) of the evidence.  While AASLD is committed to focusing on practice guidelines, the established practice guidances remain valid, essential resources for the hepatology community.

Additionally, AASLD develops quality measures to help its members measure or quantify healthcare processes and outcomes that are associated with the ability to provide high-quality health care.

Evolution of Practice Guideline Development Process

AASLD recognizes that practice guidelines are an instrumental resource for the health care community to identify, diagnose, treat, and manage care of patients with liver disease. AASLD remains committed to developing rigorous, credible, and transparent Practice Guidelines. Our practice guideline program is currently evolving to prioritize industry-accepted processes that include methodologies for levels of evidence assessment, patient representation, member input on future topics, public feedback, and diverse forms of content dissemination.

Guidelines and Guidance by Disease

Guidelines Development

AASLD strives to review and update its practice guidelines every five (5) years, as necessary. Users are cautioned that in the interim, scientific and medical developments may supersede or invalidate, in whole or in part, specific recommendations in any guideline. A guideline is considered to be "inactive" if it has not been updated by AASLD in at least five (5) years, and for this reason particular care must be exercised in placing reliance on an inactive guideline. 

AASLD commissions and provides financial support for the formulation and production of practice guidelines/guidances by volunteer experts. Financial support from commercial entities or the pharmaceutical industry is not accepted for the development of AASLD practice guidelines. 

Quality Measures

Quality measures are a tool for providers and institutions to evaluate their care quality, drive quality improvement, and deliver high-value patient care.

Patient Guidelines

Patient Guidances are adaptations of published AASLD guidances which are written specifically for patients to help them understand their liver disease. Clinicians may also provide these patient guidances to their patients as a resource during consultations.
