Hospitals differ in size and in how sick their patients are. CMS adjusts its outcome measures for that, but a star or a percentage is a starting point for questions, not a verdict.
Deaths
How many patients died within 30 days of admission, adjusted by CMS for how sick they were. Lower is better. Data from Jul 2022 – Jun 2025.
| Measure | CMS comparison | This hospital | National |
|---|---|---|---|
| All patients, hospital-wide 67 cases | Too few cases | 4.1% | 3.9% |
6 more measures had too few cases here to report.
Not reported for this hospital
CMS had too few cases here to publish results for complications, infections caught in the hospital, readmissions and return visits. That is common at small, rural and specialty hospitals, and says nothing either way about quality.

How to read this page
- Everything here is published by CMS on Care Compare. We arrange it and explain it; the star ratings and the better / worse verdicts are CMS's, not ours.
- “No different” is the most common result on most measures at most hospitals. CMS only calls a result better or worse when the difference from the national rate is statistically clear.
- Death, complication and readmission rates are adjusted by CMS for how sick patients were, so hospitals that treat sicker patients can be compared fairly.
- Infection results are ratios: 1.0 means as many infections as CMS predicted for a hospital like this one, below 1.0 is fewer.
- These are hospital-wide results. They do not rate an individual doctor, nurse or department, and they are not medical advice.
