What patients say
CMS patient survey (HCAHPS) · 42 completed surveys · patients discharged Oct 2024 – Sep 2025
89% would definitely recommend it (U.S. average 71%). 84% rated it 9 or 10 out of 10.
The patient survey (HCAHPS) asks a random sample of adult patients about their recent hospital stay. CMS adjusts the results for the mix of patients and how the survey was done, so hospitals can be compared fairly. CMS gives a star rating only to hospitals with at least 100 completed surveys, so this hospital has answer percentages but no stars. These results come from fewer than 100 completed surveys, so CMS advises using them with caution. About the data.
