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 Louis a Weiss Memorial Hospital 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.
Not reported to Medicare
Source: Patient survey (HCAHPS) - Hospital — CMS, released July 22, 2026; patients discharged October 2024 to September 2025.
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) | Not reported to Medicare |
|---|---|
| Catheter-associated urinary tract infections (CAUTI) | 0No different from the national benchmark |
| Surgical site infections after colon surgery | Not reported to Medicare |
| Surgical site infections after abdominal hysterectomy | Not reported to Medicare |
| MRSA bloodstream infections | Not reported to Medicare |
| Clostridioides difficile (C. diff) intestinal infections | 0.615No different from the national benchmark |
Source: Healthcare Associated Infections - Hospital — CMS, released July 22, 2026; data from October 2024 to September 2025.
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 | 13.2% |
|---|---|
| Deaths within 30 days: heart failure patients | 8.4% |
| Deaths within 30 days: pneumonia patients | 14.4% |
| Deaths within 30 days: COPD patients | 7.9% |
| Deaths within 30 days: stroke patients | 9.1% |
| Deaths within 30 days: coronary bypass surgery (CABG) | Not reported to Medicare |
| Serious complications (patient safety indicator PSI-90) | 1.32No different from the national rate |
| Complications after hip or knee replacement | 5.5% |
Source: Complications and Deaths - Hospital — CMS, released September 10, 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) | Not reported to Medicare |
|---|---|
| Readmitted within 30 days: heart attack | 14.8% |
| Readmitted within 30 days: heart failure | 23% |
| Readmitted within 30 days: pneumonia | 17.6% |
| Readmitted within 30 days: COPD | 19.6% |
| Readmitted within 30 days: coronary bypass surgery | Not reported to Medicare |
| Readmitted within 30 days: hip or knee replacement | 6.1% |
Source: Unplanned Hospital Visits - Hospital — CMS, released September 10, 2026; data from July 2023 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) | 210 minutesNational average: 162 minutes |
| Patients who left the emergency room before being seen (OP-22) | 5%National average: 2% |
| Sepsis patients who got all the recommended early care (SEP-1) | 36%National average: 65% |
