Frequently asked questions about hospitals

How are hospitals rated by CMS?

CMS publishes an overall star rating from 1 to 5 for most hospitals, based on quality measures grouped into categories such as mortality, safety of care, readmission, patient experience, and timely and effective care. The rating compares each hospital against others nationwide and comes from the public-domain Hospital General Information dataset used on this page.

What does a hospital's overall star rating mean?

A 5-star rating means the hospital performs much above the national average on the published measures, while 1 star means much below average. The rating is a summary of government-reported measures — a starting point for comparison, not a guarantee of any individual outcome.

What is a Critical Access Hospital?

A Critical Access Hospital is a small facility designated by CMS to provide 24/7 emergency care in rural areas. These hospitals are reimbursed differently from larger acute care hospitals, which is one reason their profiles can look different from urban facilities.

How should I use hospital ratings when choosing care?

Combine the star rating with your own needs: location, whether the hospital accepts your insurance, the services you need, and your doctor's guidance. Ratings summarize government-reported measures and do not capture every aspect of care quality.

How to choose a hospital

Start with the overall star rating, but look beneath it. The rating summarizes measures across mortality, safety, readmission, patient experience, and timely care — a hospital can score well in some categories and poorly in others. Each profile also shows the hospital type (for example, acute care or critical access) and ownership, which can be useful context.

Confirm practical details before you go: whether the hospital has emergency services, its location, and whether it accepts your insurance. For planned care, ask your doctor which hospital they recommend and why.

Ratings are a comparison tool built from government-reported data, not a guarantee of any individual outcome. Use them as one input alongside your own needs and your clinician's advice.

Ratings summarize government-reported measures — they don't capture your personal needs. Visit the facility, ask about staffing and services, and use CMS checklists. This profile is informational only and is not a recommendation.
