Patient Care and Research

Guidelines and Practice Documents

Clinical practice statements are evidence based or consensus based documents developed to help health care professionals and patients make decisions about screening, prevention or treatment of a specific health condition, promoting high quality and appropriate care. They are built from the body of established literature complemented by expert opinion.

Statements are prepared based on information available at the time the panel was conducting its research and discussions on the topic. There may be new developments that are not reflected in the current versions and may, over time, be revisited and updated. ASTRO provides guidance in five forms: Guidelines, Consensus Statements, Consensus Guidance, Analyses using the RAND/UCLA Method and White Papers, depending on the topic and evidence available.



Analysis using RAND/UCLA Method

A guidance statement using the RAND/UCLA Appropriateness Methodology where randomized clinical trials are not available or cannot provide evidence at the level of detail sufficient to apply to the wide range of patients seen in clinical practice.

Consensus Statement

A document developed by an independent panel of experts, usually multidisciplinary, convened to review the research literature for advancing the understanding of an issue, procedure, or method

Consensus Guidance

A document advancing the understanding of a procedure.


Statements that include recommendations, intended to optimize patient care, that are informed by a systematic review of evidence and an assessment of the benefits and harms of alternative care options

White Papers

Authoritative report giving information or proposals on an issue
