Guidelines and Practice Documents

Clinical practice guidelines and practice documents are evidence-based or consensus-based documents developed to assist healthcare professionals and patients with decision-making related to screening, prevention and/or treatment of a specific health condition, and to promote high quality and appropriate care. They are developed from the body of established literature complemented by expert opinion.

Documents are prepared based on information available at the time the panel conducts its literature review 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: Clinical Practice Guidelines, Consensus/Guidance Statements and White Papers, Practice Parameters and Technical Standards, and Model Policies, depending on the topic and evidence available.



Clinical Practice Guideline (CPG) "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" as defined by the National Academy of Medicine (formerly Institute of Medicine).

Consensus/Guidance Statement (CS) and White Papers (WP)

A document that provides guidance or information on topics based primarily on the consensus of a multidisciplinary panel of experts specializing in the topic. White Papers often focus on a technology or process step and may contain proposals on an issue/topic.

Practice Parameters/Technical Standards (PP) Practice Parameters describe recommended conduct in specific areas of clinical practice. They are based on analysis of current literature, expert opinion, open forum commentary and formal consensus. 
Model Policies Documents developed as a means to efficiently communicate what ASTRO believes to be correct coverage policies for radiation oncology services.
