The Illinois nurse staffing law, formally the Nurse Staffing Improvement Act at 210 ILCS 85/10.10, requires every hospital in the state to build and follow a written staffing plan that sets minimum registered nurse-to-patient levels for each inpatient unit, adjust those levels in real time based on patient acuity, and let direct care nurses drive the process through a nursing care committee. Hospitals that ignore the requirement face fines, mandatory correction plans, and potential loss of their operating license.
What Hospitals Have to Do
The plan is hospital-wide and unit-specific. It must set minimum RN-to-patient staffing levels for every inpatient care unit, including inpatient emergency departments. It cannot be built around headcount budgets. The law requires it to account for the complexity of care on each unit, the clinical judgment nurses need to exercise, patient acuity and volume, the skill mix of support staff, and whether specialized equipment is available.
Alongside the plan, each hospital must adopt an acuity model that adjusts staffing as patient needs shift during a shift or across a day. Illinois does not impose a single fixed nurse-to-patient ratio statewide. Each facility builds its own flexible system, but the system has to actually flex.
If administration declines to adopt the committee’s recommended plan or makes substantial changes to it, the chief nursing officer owes the committee a written explanation of why.
The Nursing Care Committee
The committee is where the plan gets built. Every hospital must have one, and it must meet at least six times a year. At least 55% of its members must be registered professional nurses who provide direct inpatient care, and one of those direct care nurses is chosen each year by the direct care nursing staff to serve as co-chair.
The committee’s work does not end with the initial plan. It recommends minimum staffing levels, selects and evaluates the hospital’s acuity model, and reviews whether actual staffing on each unit matches what the plan calls for. The structure is designed so the people at the bedside have real influence over how many nurses are on the floor.
Where to Find Your Hospital’s Plan
Staffing plans are not confidential. The written plan must be posted in a location that is conspicuous and accessible to both patients and direct care staff, whether physically or electronically. Any member of the public can request a copy, and the hospital must provide it. For a nurse who suspects a unit is being run below what the plan promises, that posted document is the reference point.
Penalties for Noncompliance
The penalty structure escalates with how bad and how persistent the problem is.
- A hospital that fails to implement a written staffing plan at all faces a fine of up to $500 per occurrence.
- A hospital showing a pattern or practice of failing to substantially comply with its plan must submit a plan of correction to IDPH within 60 days. Failing to comply with the correction plan can bring fines of up to $500 per occurrence.
- A second or subsequent pattern of noncompliance with a correction plan can bring fines of up to $1,000 per occurrence.
- The IDPH Director can deny, suspend, or revoke a hospital’s permit or operating license for substantial failure to comply with the Hospital Licensing Act, which includes the staffing requirements.
The per-occurrence dollar figures look modest against a hospital system’s revenue. The real leverage sits in the correction plan process and the Director’s authority over the operating license.
Protections for Nurses Who Raise Concerns
The staffing law itself prohibits hospitals from disciplining, discharging, or taking any adverse employment action against an employee solely for raising concerns about an alleged staffing violation or about nurse staffing generally. This protection is written into 210 ILCS 85/10.10 and covers every hospital employee, not just committee members.
Two additional layers sit on top of that. The Illinois Whistleblower Act (740 ILCS 174) prohibits any employer from retaliating against an employee who reports a reasonably believed violation of state or federal law to a government agency, or who refuses to participate in an activity that would violate the law. An employer cannot even maintain a policy that blocks employees from disclosing that information. A retaliated-against employee can sue for reinstatement, back pay with interest, and reasonable attorney’s fees.
Nurses who raise staffing concerns as a group also fall under the National Labor Relations Act, which protects concerted activity for mutual aid or protection. Two or more nurses who jointly bring staffing complaints to management, sign a letter about unsafe conditions, or organize around workload are protected whether or not they belong to a union.
How to File a Complaint With IDPH
Any hospital employee can file a complaint with the Illinois Department of Public Health about an alleged staffing violation. Once IDPH receives it, the agency must notify the hospital within 10 business days and may take enforcement action from there.
IDPH accepts complaints three ways:
- By phone through the Central Complaint Registry hotline at 800-252-4343.
- By email at DPH.CCR@illinois.gov for hospital-related complaints.
- Online through the IDPH Office of Health Care Regulation complaint portal, though the online form is primarily set up for nursing homes and similar facilities rather than hospitals.
Include as much detail as you can: who was involved, what happened, when and where, and whether hospital leadership already knew about the situation. You can file anonymously, but IDPH will only send a written response if you provide an address. Investigations range from a few weeks to several months depending on scope and severity.
A Note on Nursing Homes
The Nurse Staffing Improvement Act described here governs hospitals. Federal nursing home staffing rules are a separate track and recently changed. In December 2025, the Department of Health and Human Services published an interim final rule repealing the previously finalized 24/7 registered nurse requirement and the numerical staffing minimums for Medicare and Medicaid-certified nursing homes. As of February 2, 2026, the federal standard reverts to requiring RN services for at least eight consecutive hours per day, seven days a week. If your question is about a nursing home rather than a hospital, that federal framework, not the Illinois hospital staffing law, is where to start.
