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 Henry Mayo Newhall 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.

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)2.021No different from the national benchmark
Catheter-associated urinary tract infections (CAUTI)0.405No different from the national benchmark
Surgical site infections after colon surgery1.091No different from the national benchmark
Surgical site infections after abdominal hysterectomyNot reported to Medicare
MRSA bloodstream infections1.067No different from the national benchmark
Clostridioides difficile (C. diff) intestinal infections0.206Better than the national benchmark

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 patients11.6%
Deaths within 30 days: heart failure patients11%
Deaths within 30 days: pneumonia patients13.6%
Deaths within 30 days: COPD patients6.7%
Deaths within 30 days: stroke patients10%
Deaths within 30 days: coronary bypass surgery (CABG)Too few cases to report
Serious complications (patient safety indicator PSI-90)1.22No different from the national rate
Complications after hip or knee replacement6.2%

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 attack15.1%
Readmitted within 30 days: heart failure21.7%
Readmitted within 30 days: pneumonia16.5%
Readmitted within 30 days: COPD20.9%
Readmitted within 30 days: coronary bypass surgery12%
Readmitted within 30 days: hip or knee replacement6%

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)Very high (60,000 or more)
Average (median) time patients spent in the emergency room before leaving (OP-18b)174 minutesNational average: 162 minutes
Patients who left the emergency room before being seen (OP-22)1%National average: 2%
Sepsis patients who got all the recommended early care (SEP-1)89%National average: 65%
