What patients say
CMS patient survey (HCAHPS) · 83 completed surveys · patients discharged Oct 2024 – Sep 2025
82% would definitely recommend it (U.S. average 71%). 85% 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.
Infections, complications and deaths
Centers for Medicare & Medicaid Services · compared with hospitals nationwide
Death rates within 30 days
| Patients treated for | This hospital | U.S. |
|---|---|---|
| Heart failure patients | 11.6% | 11.1% |
| Pneumonia patients | 12.9% | 15.2% |
| Hospital-wide, all conditions | 4.0% | 3.9% |
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.
Other complications
None of the other safety indicators CMS compares was statistically better or worse than national.
All 3 complication measures
| Measure | This hospital | U.S. | CMS comparison |
|---|---|---|---|
| Pressure ulcers (bed sores)per 1,000 patients | 0.57 | 0.63 | Same as national |
| Falls in the hospital that caused a broken boneper 1,000 patients | 0.27 | 0.27 | Same as national |
| Collapsed lung caused by a medical procedureper 1,000 patients | 0.21 | 0.21 | Same as national |
"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.
Readmissions and return visits
Centers for Medicare & Medicaid Services · Medicare patients · Jul 2023 – Jun 2025

Medicare's readmission program
Excess readmission ratio: this hospital's predicted readmissions divided by the number expected for a typical hospital with the same patients. Above 1.00 means more readmissions than expected. 2 of 2 conditions are above 1.00.
| Condition | Ratio | Patients | Readmissions |
|---|---|---|---|
| Heart failure | 1.049 | 46 | More than expected |
| Pneumonia | 1.035 | 70 | More than expected |
Readmission rates count Medicare patients who were admitted to any acute-care hospital within 30 days of leaving this one, adjusted for how sick they were. "Better" or "worse" means CMS found the difference from the national rate statistically significant; most hospitals are "no different". Return-day and outpatient-surgery measures compare the hospital with what CMS expected for its own patients. The Readmissions Reduction Program ratios are shown as CMS publishes them; whether a hospital's payments are reduced depends on how its ratios compare with similar hospitals, so a ratio above 1.00 alone doesn't mean a penalty. About the data.

Maternity care
Centers for Medicare & Medicaid Services · reported by the hospital · Jan 2024 – Dec 2024
Maternity measures are reported by hospitals that deliver babies. The U.S. figure is the median of the hospitals CMS reports, not a CMS verdict. About the data.
Medicare spending and payment programs
Centers for Medicare & Medicaid Services
The Hospital-Acquired Condition Reduction Program cuts Medicare payments by 1% for the quarter of hospitals with the worst scores. The Hospital Value-Based Purchasing Program withholds a small share of every hospital's Medicare payments and pays it back according to the total performance score. A spending ratio of 1.00 equals the national median; spending reflects prices, the services patients received and care after discharge, not quality. Some hospitals, such as critical access, children's and cancer hospitals, are not part of these programs. About the data.
