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 Kaiser Foundation Hospital Fontana/Ontario 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.
| Summary star rating (all survey topics) | 4 of 5 stars |
|---|---|
| Overall rating of the hospital | 4 of 5 stars |
| Would recommend the hospital | 5 of 5 stars |
| Nurses communicated well | 4 of 5 stars |
| Doctors communicated well | 4 of 5 stars |
| Staff explained medicines | 4 of 5 stars |
| Information about recovery at home | 4 of 5 stars |
| Room and bathroom kept clean | 4 of 5 stars |
| Quiet at night | 4 of 5 stars |
| Rated the hospital 9 or 10 out of 10 | 80%National average: 72% |
| Would definitely recommend the hospital | 78%National average: 71% |
| Nurses “always” communicated well | 82%National average: 80% |
| Doctors “always” communicated well | 80%National average: 80% |
| Staff “always” explained medicines before giving them | 66%National average: 62% |
| Were given information about recovery at home | 89%National average: 86% |
| Room and bathroom “always” clean | 75%National average: 74% |
| Area around the room “always” quiet at night | 62%National average: 60% |
| Completed surveys | 1,560Response rate: 19% |

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) | 0.103Better than the national benchmark |
|---|---|
| Catheter-associated urinary tract infections (CAUTI) | 0.377Better than the national benchmark |
| Surgical site infections after colon surgery | 0.345Better than the national benchmark |
| Surgical site infections after abdominal hysterectomy | 0.88No different from the national benchmark |
| MRSA bloodstream infections | 0.378Better than the national benchmark |
| Clostridioides difficile (C. diff) intestinal infections | 0.234Better 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 patients | Too few cases to report |
|---|---|
| Deaths within 30 days: heart failure patients | Too few cases to report |
| Deaths within 30 days: pneumonia patients | 16% |
| Deaths within 30 days: COPD patients | Too few cases to report |
| Deaths within 30 days: stroke patients | 15.8% |
| Deaths within 30 days: coronary bypass surgery (CABG) | Too few cases to report |
| Serious complications (patient safety indicator PSI-90) | 0.98No different from the national rate |
| Complications after hip or knee replacement | 4.2% |
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 attack | 13.4% |
| Readmitted within 30 days: heart failure | 21.6% |
| Readmitted within 30 days: pneumonia | 19.1% |
| Readmitted within 30 days: COPD | 21.4% |
| Readmitted within 30 days: coronary bypass surgery | 10.4% |
| Readmitted within 30 days: hip or knee replacement | 5% |
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.
| Average (median) time patients spent in the emergency room before leaving (OP-18b) | Not reported to Medicare |
|---|---|
| Patients who left the emergency room before being seen (OP-22) | Not reported to Medicare |
| Sepsis patients who got all the recommended early care (SEP-1) | 86%National average: 65% |
