Why this actor

The Centers for Medicare & Medicaid Services (CMS) publishes the Hospital Compare dataset — the federal government's official hospital quality benchmark. It is the same data that powers Medicare.gov's hospital finder and is used by insurers, health systems, investors, and researchers to compare hospital performance. The underlying Socrata API is open but requires understanding dataset IDs and SODA query syntax. This actor handles that complexity and gives you one clean record per hospital.

• 4,500+ hospitals covered across all US states.
• Overall star rating (1–5 stars) from CMS's composite methodology.
• Filter by state, city, or hospital name for targeted pulls.
• No API key — official CMS Provider Data Catalog.

FAQ

Do I need an API key? No — the CMS Provider Data Catalog is fully open.

How current is the data? CMS updates the Hospital Compare dataset quarterly. The actor always queries the live endpoint.

How many hospitals are covered? Approximately 4,500 Medicare-certified acute care hospitals across all 50 states.

Can I get HCAHPS patient satisfaction scores? The overall star rating incorporates HCAHPS. For raw HCAHPS survey scores by domain (communication with nurses, responsiveness, etc.), contact us — we can build a companion actor on the HCAHPS-specific CMS dataset.

What is the star rating based on? CMS calculates the overall star rating from up to 5 care areas: mortality, safety of care, readmission, patient experience, and timely and effective care. Hospitals with fewer than 3 scored groups receive no rating.

Can I filter to high-performing hospitals only? Yes — set minStars to 4 or 5 to retrieve only top-rated hospitals in your target state or city.

Who uses this data? Healthcare investors benchmarking acquisition targets; health system consultants comparing regional performance; insurers building network adequacy models; researchers studying hospital quality variation; journalists covering healthcare.

How far back does the data go? The live endpoint reflects the most recent CMS release. Historical data is not available via this actor — CMS archives prior releases at data.cms.gov if you need longitudinal comparison.

Can I automate regular refreshes? Yes — schedule this actor quarterly on Apify to stay current with CMS updates.
