Of these, 121 facilities operate an emergency department, an important signal for communities that rely on nearby acute-care access.

At the top of the quality distribution, 6 hospitals have earned the highest 5-star CMS overall rating in Oklahoma. The single highest-rated facility in the state registry is Ascension St John Broken Arrow in Broken Arrow, currently listed at 5/5 stars.
