How we grade hospitals
What data goes into a grade?
CMS Care Compare Hospital General Information: CMS overall rating (25), Mortality (25), Safety of care (25), Readmission (25). Each metric is percentile-ranked against Illinois hospitals of the same type; A ≥ 72, B ≥ 58, C ≥ 42, D ≥ 28, F below. Hospitals with fewer than three of the four metrics are shown as "Not graded".
Why is a well-known hospital graded C?
The grade measures outcomes CMS reports — death rates, complications, infections, readmissions — not reputation, research or specialist rankings. A large teaching hospital that treats the sickest patients can score average on these measures. Use the grade as one input, alongside the specialists you need.
Can a hospital pay to improve its grade?
No. Grades are computed from public data and have no editable field. Nothing on this page is sponsored.
