Provide Feedback


Our new web feedback tool allows us to better track and manage feedback coming from a variety of sources.

The primary focus is the external stakeholder review of ACR Appropriateness Criteria process. After we release new and revised AC topics, we will send an email to those who have signed up for notifications so they can review the topic content. For about two months after each release, we will focus on reviewing your comments for critical information to improve these topics. This method will ensure that your input will be reviewed and addressed when the topic is updated.

Also, reviewers, such as ACR members, other specialty physicians, patients, payers, health care administrators, etc., may comment at any time on any topic. Anyone can suggest new topics, splitting or grouping topics together, suggest new references or evidence for the expert panel to consider, ask questions or clarifications, or comment on the ACR AC process and methodology. We will do our best to provide timely responses but eventually all input will be reviewed and addressed.

Please let us know if you have any suggestions for the Review page so we can collect and address better your input and comments. Learn more
