Frequently Asked Questions

What data is used in this hospital comparison?

This comparison tool uses data from the Centers for Medicare & Medicaid Services (CMS) Hospital Compare program. It includes overall star ratings, quality measures (mortality, safety, readmissions), patient experience (HCAHPS) surveys, healthcare-associated infection rates, unplanned visit measures, Medicare spending per episode, and maternal health measures.

How are CMS star ratings calculated?

CMS overall hospital star ratings are calculated on a scale of 1 to 5 stars using data from multiple quality measures across five categories: mortality, safety of care, readmission, patient experience, and timely and effective care. Hospitals must have sufficient data in at least three measure groups to receive a star rating.

What does "Better than National" mean?

When a quality measure is marked "Better than National," it means the hospital's performance on that specific measure is statistically significantly better than the national benchmark. Similarly, "Worse than National" indicates the hospital performs significantly below the benchmark, and "Same as National" means no statistically significant difference.

What are HCAHPS patient experience surveys?

HCAHPS (Hospital Consumer Assessment of Healthcare Providers and Systems) is a standardized patient satisfaction survey administered to a random sample of recently discharged patients. It measures aspects of hospital care such as communication with doctors and nurses, responsiveness of staff, cleanliness, discharge information, and overall rating.

How often is the comparison data updated?

CMS publishes updated Hospital Compare data quarterly. Our database is refreshed with each new CMS release to provide the most current quality metrics available for comparison.

Can I compare more than two hospitals?

Currently this tool supports side-by-side comparison of two hospitals at a time. For broader comparisons, check our Rankings pages for top-rated, safest, and best patient experience hospitals.
