About the Medicare star rating

Medicare quality data

What Ascension Saint Thomas Three Rivers 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.

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: pneumonia patients23.8%
Not reported to MedicareDeaths within 30 days: coronary bypass surgery (CABG); Serious complications (patient safety indicator PSI-90); Complications after hip or knee replacement

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)16.5%
Readmitted within 30 days: pneumonia16%

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.
