What patients say
CMS patient survey (HCAHPS) · 51 completed surveys · patients discharged Oct 2024 – Sep 2025
86% would definitely recommend it (U.S. average 71%). 83% 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.

Risk-adjusted rates. CMS has not published a statistical better/worse comparison for these death rates in the current release, so small differences from the U.S. rate may be chance.
"Better" or "worse" means CMS found the difference from the national benchmark statistically significant; most hospitals are "no different". Infection results compare the infections a hospital reported with the number predicted for a hospital of its size and type (a ratio below 1 means fewer than predicted). Death and complication rates are risk-adjusted for how sick patients were. Each death rate counts deaths within 30 days of a hospital stay, pooled over one to three years of Medicare patients depending on the measure. About the data.
