Infections, complications and deaths
Centers for Medicare & Medicaid Services · compared with hospitals nationwide
Death rates within 30 days
| Patients treated for | This hospital | U.S. |
|---|---|---|
| Heart failure patients | 12.8% | 11.1% |
| Pneumonia patients | 16.2% | 15.2% |
| Hospital-wide, all conditions | 4.1% | 3.9% |
Risk-adjusted rates. CMS has not published a statistical better/worse comparison for these death rates in the current release, so small differences from the U.S. rate may be chance.
"Better" or "worse" means CMS found the difference from the national benchmark statistically significant; most hospitals are "no different". Infection results compare the infections a hospital reported with the number predicted for a hospital of its size and type (a ratio below 1 means fewer than predicted). Death and complication rates are risk-adjusted for how sick patients were. Each death rate counts deaths within 30 days of a hospital stay, pooled over one to three years of Medicare patients depending on the measure. About the data.

Return trips after a stay or procedure
Readmission rates count Medicare patients who were admitted to any acute-care hospital within 30 days of leaving this one, adjusted for how sick they were. "Better" or "worse" means CMS found the difference from the national rate statistically significant; most hospitals are "no different". Return-day and outpatient-surgery measures compare the hospital with what CMS expected for its own patients. The Readmissions Reduction Program ratios are shown as CMS publishes them; whether a hospital's payments are reduced depends on how its ratios compare with similar hospitals, so a ratio above 1.00 alone doesn't mean a penalty.
