Medicare quality data

What patients said (patient survey)
What this means: Patients who stayed overnight answered a national survey (HCAHPS) about their stay. More stars mean patients reported a better experience than at other hospitals. The percentages show how often patients gave the best answer, next to the national average.

Infections caught in the hospital
What this means: CMS compares the number of infections patients caught in this hospital with the number expected for a hospital like it. The number shown is that ratio: below 1 means fewer infections than expected, above 1 means more. “Better” or “worse” is shown only when the difference is clear in the data.
| Central line bloodstream infections (CLABSI) | 0.486No different from the national benchmark |
|---|---|
| Catheter-associated urinary tract infections (CAUTI) | 0.635No different from the national benchmark |
| Surgical site infections after colon surgery | 0No different from the national benchmark |
| MRSA bloodstream infections | 1.408No different from the national benchmark |
| Clostridioides difficile (C. diff) intestinal infections | 0.386Better than the national benchmark |
| Not reported to Medicare | Surgical site infections after abdominal hysterectomy |

Complications and deaths
What this means: Death rates are the share of patients who died within 30 days of going into the hospital for that condition, adjusted for how sick they were. PSI-90 combines several serious complications (a lower number is better). “No different from the national rate” is the most common result and means the hospital is in line with hospitals nationwide.
| Deaths within 30 days: heart attack patients | 10.8% |
|---|---|
| Deaths within 30 days: heart failure patients | 9.4% |
| Deaths within 30 days: pneumonia patients | 12.6% |
| Deaths within 30 days: COPD patients | 6.8% |
| Deaths within 30 days: stroke patients | 8.7% |
| Serious complications (patient safety indicator PSI-90) | 1.01No different from the national rate |
| Complications after hip or knee replacement | 3.4% |
| Not reported to Medicare | Deaths within 30 days: coronary bypass surgery (CABG) |
Source: Complications and Deaths - Hospital — CMS, released October 20, 2026; data from July 2022 to June 2025.
Return visits to the hospital (readmissions)
What this means: The share of patients who had to be admitted to a hospital again within 30 days after going home, adjusted for how sick they were. A lower percentage is better.
| Returned to any hospital within 30 days (all patients) | 14.3% |
|---|---|
| Readmitted within 30 days: heart failure | 19.4% |
| Readmitted within 30 days: pneumonia | 16.8% |
| Readmitted within 30 days: COPD | 19.2% |
| Readmitted within 30 days: hip or knee replacement | 4.8% |
| Not reported to Medicare | Readmitted within 30 days: coronary bypass surgery |
| Too few cases to report | Readmitted within 30 days: heart attack |
Source: Unplanned Hospital Visits - Hospital — CMS, released October 20, 2026; data from July 2024 to June 2025.
Emergency room times and sepsis care
What this means: ER time is the middle (median) time from arriving at the emergency room to leaving it; busier ERs usually have longer times, so the ER volume is shown too. Leaving before being seen: a lower percentage is better. Sepsis is a life-threatening reaction to an infection; a higher percentage means more patients got every recommended early step.
| Emergency room volume (patients per year) | High (40,000–59,999) |
|---|---|
| Average (median) time patients spent in the emergency room before leaving (OP-18b) | 215 minutesNational average: 162 minutes |
| Patients who left the emergency room before being seen (OP-22) | 2%National average: 2% |
| Sepsis patients who got all the recommended early care (SEP-1) | 64%National average: 66% |

Hospital-Acquired Condition Reduction Program
What this means: Medicare gives each hospital a Total HAC Score built from patient-safety complications and from infections caught in the hospital. The quarter of hospitals with the highest (worst) scores gets a reduction in its Medicare payments. A lower score is better.
CMS says: Hospitals with a Total HAC Score above the 75th percentile of the Total HAC Score distribution will be subject to a 1-percent payment reduction.
| Medicare payment reduction, fiscal year 2026 | NoCMS lists no payment reduction for this hospital. |
|---|---|
| Total HAC Score | -0.0079Lower is better. Hospitals above the 75th percentile of all scores get the reduction. |
Source: Hospital-Acquired Condition (HAC) Reduction Program — CMS, released January 26, 2026; patient-safety data from July 2022 to June 2024 and infection data from January 2023 to December 2024.
Hospital Readmissions Reduction Program
What this means: For six conditions, Medicare compares how often this hospital’s patients had to go back into a hospital within 30 days with how often that happens at an average hospital with similar patients. The ratio is that comparison: 1 means as many readmissions as expected, above 1 means more than expected (CMS calls these “excess readmissions”), below 1 means fewer.
CMS says: In October 2012, CMS began reducing Medicare payments for subsection(d) hospitals with excess readmissions under the Hospital Readmissions Reduction Program (HRRP).
| Heart failure | 0.8520Fewer readmissions than expected |
|---|---|
| Pneumonia | 0.9934Fewer readmissions than expected |
| COPD (chronic lung disease) | 0.9964Fewer readmissions than expected |
| Hip or knee replacement | 0.8156Fewer readmissions than expected |
| No result published | Heart attack; Coronary bypass surgery (CABG) (not reported, or too few cases) |
Source: Hospital Readmissions Reduction Program — CMS, released January 26, 2026; patients discharged July 2021 to June 2024.
Hospital Value-Based Purchasing Program
What this means: Medicare scores hospitals in four areas, each from 0 to 100, and combines them into a Total Performance Score from 0 to 100. A higher score means better results on these measures. Medicare uses the score to adjust what it pays the hospital.
CMS says: This program adjusts payments to hospitals under the Inpatient Prospective Payment System (IPPS) based on the quality of care they deliver.
| Total Performance Score | 29.67 out of 100Median of the 2,455 hospitals in the program: 29.50 |
|---|---|
| Clinical outcomes (deaths and complications) | 52.00 out of 100 |
| Person and community engagement (patient survey) | 15.00 out of 100 |
| Safety (infections and sepsis care) | 31.67 out of 100 |
| Efficiency and cost reduction (Medicare spending) | 20.00 out of 100 |

Medicare spending per patient (MSPB)
What this means: This compares what Medicare spent on a hospital stay, counting the 3 days before it and the 30 days after, with the national median hospital, after adjusting for the patient’s age and health and for local prices. A ratio of 1.00 is the national median hospital; below 1.00 means Medicare spent less, above 1.00 means more. It measures the cost to Medicare, not the quality of care.
CMS says: The Medicare Spending Per Beneficiary (MSPB) Measure shows whether Medicare spends more, less, or about the same for an episode of care (episode) at a specific hospital compared to all hospitals nationally.
| Medicare spending per patient, ratio | 0.97Below the national median hospital (1.00): Medicare spent less |
