About the Medicare star rating
CMS (the federal Medicare agency) gives many hospitals an overall rating from 1 to 5 stars, based on measures of mortality, safety, readmissions, patient experience and timely care. It is one piece of information: ask your doctor what matters for your care. See the full Medicare profile →
Medicare quality data
What St Michael's Hospital - CAH reported to Medicare (CMS), the federal agency that publishes these results for hospitals nationwide. These are averages for many patients, not a prediction for any one person: ask your doctor what matters for your care. In a medical emergency, call 911.
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.
| Rated the hospital 9 or 10 out of 10 | 87%National average: 72% |
|---|---|
| Would definitely recommend the hospital | 69%National average: 71% |
| Nurses “always” communicated well | 89%National average: 80% |
| Doctors “always” communicated well | 93%National average: 80% |
| “Always” got help as soon as they wanted | 81%National average: 64% |
| Staff “always” explained medicines before giving them | 59%National average: 62% |
| Were given information about recovery at home | 88%National average: 86% |
| Room and bathroom “always” clean | 86%National average: 73% |
| Not reported to Medicare | Summary star rating (all survey topics); Overall rating of the hospital; Would recommend the hospital; Nurses communicated well; Doctors communicated well; Patients got help quickly from staff; Staff explained medicines; Information about recovery at home; Room and bathroom kept clean; Restfulness of Environment; Care Coordination; Symptoms After Stay |
| Completed surveys | 29Response rate: 34% |
Source: Patient survey (HCAHPS) - Hospital — CMS, released October 19, 2026; patients discharged January 2025 to December 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) | 15.9% |
|---|---|
| Not reported to Medicare | Readmitted within 30 days: heart attack; Readmitted within 30 days: coronary bypass surgery; Readmitted within 30 days: hip or knee replacement |
| Too few cases to report | Readmitted within 30 days: heart failure; Readmitted within 30 days: pneumonia; Readmitted within 30 days: COPD |
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) | Low (under 20,000) |
|---|---|
| Average (median) time patients spent in the emergency room before leaving (OP-18b) | 112 minutesNational average: 162 minutes |
| Patients who left the emergency room before being seen (OP-22) | 0%National average: 2% |
| Not reported to Medicare | Sepsis patients who got all the recommended early care (SEP-1) |
Source: Timely and Effective Care - Hospital — CMS, released October 19, 2026; data from January 2024 to December 2024.
Not reported to Medicare: infections caught in the hospital, complications and deaths. For these topics Medicare shows no result for this hospital (not reported, or too few cases).
