Quality Ratings & Measures
CMS evaluates hospitals across five quality domains. Here's how Memorial Hermann Hospital System compares:
Quality data from CMS Hospital Compare. "Better than national" means statistically significantly better than the national average. Spending uses the CMS MSPB measure (Medicare Spending Per Beneficiary) index, where 1.000 is national average and values above/below 1.000 indicate higher/lower spending.
Patient Experience (HCAHPS Survey)
The HCAHPS survey is a standardized, national survey of hospital patients. It measures how patients perceive their care — including communication with doctors and nurses, responsiveness of staff, cleanliness, and discharge information. Higher percentages indicate better performance.

|---|---|---|
| Central Line Associated Bloodstream Infection (ICU + select Wards): Lower Confidence Limit | 0.354 | Better than the National Benchmark |

How to read this: "Better than national" means the hospital's infection rate is statistically significantly lower than the national average — a sign of strong infection-control protocols (hand hygiene, sterilization, catheter management). "Worse than national" may warrant asking the hospital about their improvement initiatives.
Infection data reported to the CDC's National Healthcare Safety Network (NHSN).
Complications & Deaths
CMS tracks post-surgical complications and mortality rates for common procedures and conditions (heart attack, heart failure, pneumonia, hip/knee replacement, and more). These measures reflect how patients actually fare at this hospital compared to the national average.
| Measure | Score | Patients | vs. National |
|---|---|---|---|
| Rate of complications for hip/knee replacement patients | 3.8 | 30 | No Different Than the National Rate |
| Hybrid Hospital-Wide All-Cause Risk Standardized Mortality Rate | 3.5 | 4,458 | Better Than the National Rate |
| Death rate for heart attack patients | 14.9 | 380 | Worse Than the National Rate |
| Death rate for CABG surgery patients | 2.4 | 219 | No Different Than the National Rate |
| Death rate for COPD patients | 9.9 | 319 | No Different Than the National Rate |
| Death rate for heart failure patients | 9.8 | 1,299 | Better Than the National Rate |
| Death rate for pneumonia patients | 14.7 | 1,451 | No Different Than the National Rate |
| Death rate for stroke patients | 12 | 635 | No Different Than the National Rate |
| Pressure ulcer rate | 0.26 | 17,391 | Better Than the National Rate |
| Death rate among surgical inpatients with serious treatable complications | 137.67 | 432 | Better Than the National Rate |

| Perioperative pulmonary embolism or deep vein thrombosis rate | 4.34 | 5,295 | No Different Than the National Rate |
| Postoperative sepsis rate | 9.19 | 1,305 | Worse Than the National Rate |
| Postoperative wound dehiscence rate | 2.08 | 1,174 | No Different Than the National Rate |
| Abdominopelvic accidental puncture or laceration rate | 0.99 | 4,154 | No Different Than the National Rate |
| CMS Medicare PSI 90: Patient safety and adverse events composite | 1.02 | N/A | No Different Than the National Value |
What to consider: A "worse than national" rating on mortality or complications is a serious signal — particularly for elective procedures where you have time to choose a facility. For emergency care, proximity and speed often outweigh these metrics. Ask the hospital about their outcomes for your specific procedure.
Readmissions & Unplanned Hospital Visits
A readmission means a patient returned to the hospital within 30 days of discharge. High readmission rates can signal gaps in discharge planning, patient education, or follow-up care coordination. CMS penalizes hospitals with excess readmissions through the HRRP.
| Measure | Score | Patients | vs. National |
|---|---|---|---|
| Hospital return days for heart attack patients | 51.4 | 372 | More Days Than Average per 100 Discharges |
| Hospital return days for heart failure patients | 19.7 | 1,508 | More Days Than Average per 100 Discharges |
| Hospital return days for pneumonia patients | 22.5 | 1,483 | More Days Than Average per 100 Discharges |
| Hybrid Hospital-Wide All-Cause Readmission Measure (HWR) | 14.8 | 7,528 | No Different Than the National Rate |
| Rate of unplanned hospital visits after colonoscopy (per 1,000 colonoscopies) | 12.7 | 2,275 | No Different Than the National Rate |
| Rate of inpatient admissions for patients receiving outpatient chemotherapy | N/A | 0 | Number of Cases Too Small |
| Rate of emergency department (ED) visits for patients receiving outpatient chemotherapy | N/A | 0 | Number of Cases Too Small |
| Ratio of unplanned hospital visits after hospital outpatient surgery | 1 | 1,658 | No Different than expected |
| Acute Myocardial Infarction (AMI) 30-Day Readmission Rate | 14.3 | 372 | No Different Than the National Rate |
| Rate of readmission for CABG | 11.4 | 213 | No Different Than the National Rate |
| Rate of readmission for chronic obstructive pulmonary disease (COPD) patients | 17.8 | 344 | No Different Than the National Rate |
| Heart failure (HF) 30-Day Readmission Rate | 20 | 1,508 | No Different Than the National Rate |
| Rate of readmission after hip/knee replacement | 5.6 | 28 | No Different Than the National Rate |
| Pneumonia (PN) 30-Day Readmission Rate | 16.7 | 1,483 | No Different Than the National Rate |
What to ask: If this hospital has higher-than-average readmission rates, ask about their discharge process — do they provide follow-up appointments, medication reconciliation, and clear care instructions before you leave?
