Hospital Compare / Care Compare: CMS Hospital Public Reporting
CMS Care Compare (formerly Hospital Compare) publishes hospital quality measure performance, readmission rates, mortality rates, patient experience scores, and overall star ratings for every Medicare-participating hospital.
What's published on Care Compare?
Care Compare aggregates seven categories of hospital data: HCAHPS patient experience scores, timely and effective care measures, complications and deaths, unplanned hospital visits (readmissions), psychiatric unit services, payment and value of care, and Medicare patient counts. Data is refreshed quarterly with a roughly six-month reporting lag.
Why public reporting drives behavior
Patients shop on Care Compare. Health plans use the data in network design. Employers use it for direct contracting. Hospitals that score in the bottom quartile lose volume to higher-rated competitors over time. The reputational impact often exceeds the direct CMS payment impact.

Patient cohorts driving each underperforming measure surface to the workflow team in real time.
