Nursing Home Staffing in Illinois: What Families Need to Know
Families searching for nursing home care in Illinois face a challenging landscape. The state's 658 facilities average 3.50 HPRD — below the national average of 3.90. Only 43.77% meet the CMS staffing benchmark, compared to 65.8% nationally. That means more than 56% of facilities are operating below what federal researchers once set as the minimum acceptable standard.
With 235 facilities (35.7%) earning a D or F, the margin between adequate care and understaffed care is thinner here than in most states. For the 61,638 residents depending on these homes, the staffing data is more than a number — it's a measure of how much individual attention they receive each day.
Quality varies widely across Illinois's nursing homes. While 34.8% earn a B or better, 35.7% fall to D or F. That spread reinforces why facility-level data matters more than any state average — the home two miles away might be a completely different experience from the one down the block.

The Illinois Nursing Home Landscape
Illinois operates 658 Medicare and Medicaid certified nursing homes serving approximately 61,638 residents daily. Staffing levels range from well above the research recommendation to critically understaffed — a spread that makes facility-level data essential for any family evaluating care options.
The state averages 3.50 total nurse HPRD, which is 0.39 hours below the national average of 3.90. RN coverage averages 0.73 HPRD (national: 0.68), and 36.02% of facilities meet the 0.75 RN research recommendation. The grade distribution shows 229 facilities (34.8%) earning a B or better, while 235 (35.7%) fall to D or F.

Additional Metrics
- Median HPRD: 3.36 (less skewed by outliers than the average)
- Meet Research Recommendation (4.10): 18.84% of facilities
- RN Recommendation (0.75): 36.02% of facilities
- Agency/Contract Staff: 5.64% of total hours
What This Means for Families
RN staffing averages 0.73 HPRD — slightly above the national average of 0.68. About 36.02% of facilities meet the 0.75 research recommendation. Since registered nurses are the clinical decision-makers in any facility, this metric is the single best predictor of whether problems get caught early or escalate.
Weekend staffing drops by an average of 15.24% — roughly in line with the national pattern. Individual facilities vary, so checking the daily staffing data for any facility you're considering is worthwhile.
Agency/contract staff account for 5.64% of hours, which is near the national average. This indicates a mix of permanent and temporary workers — worth asking about at any specific facility you're evaluating.
How Nursing Home Ratings Are Calculated
Our letter grades are based on Hours Per Resident Day (HPRD) — the total nursing staff hours a facility provides divided by its daily resident count. This metric normalizes for facility size, so a 200-bed home and a 20-bed home are measured on the same scale.
The grade thresholds are anchored to two evidence-based benchmarks:
- 3.48 HPRD — the staffing level CMS established through formal rulemaking as an appropriate standard. (The regulatory requirement was subsequently suspended, but the underlying research remains valid and widely cited.)
- 4.10 HPRD — the level recommended by the landmark CMS-commissioned STRIVE study as the minimum to prevent quality problems.
Grades A+ and A correspond to facilities meeting or exceeding the research recommendation. Grade B meets the CMS benchmark. Grades C through F fall below in progressively concerning ways.
All data comes from CMS Staffing & Quality Data — daily reports that every nursing home is legally required to submit. No facility pays to be rated. No rating is influenced by advertising or referral relationships.

Key Takeaways for Families in Illinois
-
Check the facility-level grade, not just the state average. Illinois's 3.50 HPRD average masks a range from A+ to F. Every facility is different.
-
RN staffing is the most important single metric. Only 36.02% of Illinois facilities meet the 0.75 RN recommendation. Prioritize homes with strong registered nurse coverage — that's where clinical problems get caught early.
-
Ask about weekends. Illinois facilities drop staffing by 15.24% on weekends on average. A weekend visit may not reflect typical staffing — check the daily data.
-
Look at the trend direction. A facility that's improving from C toward B may be a better choice than one declining from B toward C. Four quarters of trend data reveal the direction.
-
Review the inspection history. Staffing data measures resources; inspection data measures outcomes. A facility with thin staffing and repeated citations is showing two different signals pointing the same direction.
