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 Oct 2024 – Sep 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. 4 of 6 conditions are above 1.00.

ConditionRatioPatientsReadmissions
Hip or knee replacement 1.095 – More than expected
Heart bypass surgery 1.085 94 More than expected
Heart failure 1.044 352 More than expected
Heart attack 1.012 138 More than expected
Pneumonia 0.993 292 Fewer than expected
COPD 0.959 80 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.
