Medicare Spending Index (MSPB)
Near National Avg

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.

Healthcare-Associated Infections (HAI)

Healthcare-associated infections are one of the most important safety metrics when evaluating a hospital. These infections are acquired during a hospital stay, not the reason for admission. CMS tracks rates for specific infection types and compares each hospital to 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.

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.

MeasureScorePatientsvs. National
Hospital return days for heart attack patients-21.669Fewer Days Than Average per 100 Discharges

Rate of readmission after hip/knee replacementN/A0Number of Cases Too Small
Pneumonia (PN) 30-Day Readmission Rate15.5152No 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?

What to Do with This Information

Hospital quality data is most useful when paired with your specific situation. Here's how to act on it:

  • Check network status: Before choosing this hospital, verify it's in-network for your Medicare Advantage plan. Out-of-network care can cost significantly more.
  • Ask about specific outcomes: If you're considering an elective procedure, ask the hospital for their outcomes data on that specific surgery — not just overall ratings.
  • Compare nearby options: Use the nearby hospitals section above to compare quality scores across facilities in the area.
  • Review your Medicare plan: Your plan's network determines which hospitals you can access affordably. Use our enrollment checklist to stay organized if you're switching plans. Check enrollment deadlines →
  • Talk to your doctor: Ask your primary care physician which hospitals they're affiliated with and whether they're in-network for your plan. Print our doctor questions checklist →
