"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), for Jan 2025 – Dec 2025. 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.

Medicare's readmission program

Excess readmission ratio: this hospital's predicted readmissions divided by the number expected for a typical hospital with the same patients. Above 1.00 means more readmissions than expected.

ConditionRatioPatientsReadmissions
Heart attack 0.908 160 Fewer than expected
COPD 0.881 – Fewer than expected
Heart failure 0.869 330 Fewer than expected
Pneumonia 0.863 318 Fewer than expected
Hip or knee replacement 0.819 – Fewer than expected

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.
