Important
This article explains how hospital quality data works and is for general information only. It is not medical advice and must not be used to decide whether to seek, delay or refuse care — that is a decision for you and a clinician who knows your situation.
CMS quality measures describe care delivered during earlier reporting periods and are refreshed roughly quarterly. A hospital's staffing, services and performance can change well before the published numbers do.
