Guide to Patient Experience Surveys and Ratings

CGH Medical Center values the relationships we have with our patients and their loved ones. As part of our commitment to you, we now post our physicians’ patient experience ratings online.

To assist you, we’ve developed this guide to help patients, family members and those considering appointments with our physicians and providers, so you can understand how we capture and report our patient experience ratings.
