Frequently Asked Questions

Q: Why do I need to worry about a hospital's safety record? Aren't they all safe?

Q: Where does the patient safety performance data originate?
A: The performance measures underlying the Ashbec Hospital Patient Safety Rankings are reported by the hospitals to the Center for Medicare and Medicaid Services (CMS). CMS makes the data publicly available on their Hospital Compare website.
