What the Illinois Nursing Home Record Reveals
Illinois hosts 666 Medicare- and Medicaid-certified nursing facilities operating 84,975 total certified beds (128 beds/home mean), with a statewide average CMS overall rating of 2.5 out of 5 stars - lower-tercile among ≥15-home peers (cut 3.0). The tip is floor-heavy: 247 one-star (37%) vs 90 five-star (14%). CMS ratings are state-normalized, so the same absolute inspection record may place differently in Illinois than in a state with a different facility mix.
Statewide staffing reports an average of 0.72 registered-nurse hours per resident day across Illinois facilities (CMS payroll-based nurse staffing file). Nursing staff turnover statewide averages 44.5% on the same CMS measure. Staffing levels and turnover feed the inspection and quality-measure scores that CMS uses in the overall star rating; the Illinois figures above should be read against the federal CMS 2024 minimum-staffing rule, which phases in HPRD floors over several years and will reshape this distribution for facilities currently operating below the thresholds.
For families evaluating nursing home options in Illinois, the statewide averages above set the backdrop, but placement decisions ultimately turn on facility-level records: the specific deficiencies cited at the most recent inspection, the staffing hours actually logged (as opposed to budgeted), the enforcement history of fines and payment denials, and direct observation through in-person visits. Every facility listed below links to its full CMS record on this site. Data is sourced from CMS Nursing Home Compare and Provider Data; figures reflect the most recent refresh and should be verified with each facility and the Illinois state survey agency before any placement decision is finalized.

How the CMS fields are recorded
The CMS Five-Star Quality Rating program publishes separate facility fields for health inspections, total nurse staffing hours per resident day, and quality measures drawn from MDS (Minimum Data Set) clinical assessments. CMS normalizes each star field against same-state peers before combining them into the overall rating shown in this registry.
PlainNursing aggregates the current CMS facility records for Illinois and displays the source fields and state-relative ranks above. Those records describe the reported dataset only; they do not establish suitability, availability, admissions, or any individual’s outcome.
