Understand an OIG Investigation of a CILA in Illinois

By Mac Mahony, last updated January 6, 2027

An OIG investigation of a CILA is the State’s process for deciding whether abuse, neglect, or financial exploitation happened. Mixan Mahony, LLC represents families throughout Illinois. The short answer is that the IDHS Office of the Inspector General investigates allegations at agencies licensed, funded, or certified by the Department and issues an investigative report stating whether each allegation is substantiated, unsubstantiated, or unfounded (20 ILCS 1305/1-17). That finding is important, but it does not decide a civil case.

What does an OIG investigation finding mean for a CILA resident?

The Office of the Inspector General issues a report finding each allegation substantiated, unsubstantiated, or unfounded (20 ILCS 1305/1-17). A civil injury claim is decided separately, under its own standard of proof, so an unsubstantiated finding does not by itself end a family’s options.

5 critical facts about OIG findings

1. Three outcomes: substantiated, unsubstantiated, or unfounded (1-17).
2. Scope: agencies operated, licensed, funded, or certified by IDHS (1-17(a)).
3. Immediate action. The Inspector General can act to prevent further abuse (1-17(e)).
4. Employee removal. An employee reasonably believed to have committed serious abuse is barred from contact with residents (405 ILCS 5/3-210).
5. Separate from court. A civil claim is decided on its own evidence.

Using an investigation in a civil claim

OIG reports, interviews, and the documents gathered during an investigation can help a family understand what happened. A lawyer can request records through the proper channels and compare the findings with medical records and staffing logs. Learn more about group home wrongful death claims and our practice areas.

How fault rules apply

In Illinois negligence cases, 735 ILCS 5/2-1116 bars recovery only if the injured person is found more than 50% at fault, and otherwise reduces the recovery by that share. When several defendants are liable, all of them are jointly and severally liable for medical expenses, and a defendant 25% or more at fault is also jointly and severally liable for other damages (2-1117). An OIG finding addresses staff conduct; fault in a civil case is decided by a judge or jury.

What an OIG investigation claim can include

Damages in an OIG investigation claim can include medical and therapy costs, the cost of moving to a safer placement, pain and suffering, emotional distress, and loss of normal life. In a death case, the Wrongful Death Act allows recovery for the family’s losses (740 ILCS 180/2). Investigation records often help document the timeline of harm.

Our Illinois CILA abuse and neglect lawyers review provider records, incident reports, and investigation findings to value each claim.

Illinois courts, agencies, and records for this kind of claim

In Illinois, these cases are generally filed in the circuit court for the county where the injury happened or where a defendant resides (735 ILCS 5/2-101). Start by requesting ER, imaging, and follow-up treatment records and the Individual Service Plan (ISP) and any behavior support plan; reports and investigations usually involve the IDHS Office of the Inspector General (OIG), which investigates abuse and neglect in CILAs under 59 Ill. Adm. Code 50, plus local police when a crime may have occurred.

Checklist: records to request

1. ER, imaging, and follow-up treatment records
2. The Individual Service Plan (ISP) and any behavior support plan
3. Unusual incident reports and the OIG case number
4. Staffing and shift logs for the day of the injury
5. The Illinois Traffic Crash Report from the responding agency

If your loved one has a guardian, the guardian (or the court that appointed the guardian in the county where the injury happened) should be part of these decisions.

Our office is in Chicago, and because Illinois law licenses come from the Illinois Supreme Court and cover the whole state, our attorneys can file and try this case in the county where the injury happened. We offer virtual consultations and electronic document signing.

How do the CILA rules define a critical incident?

Under 59 Ill. Adm. Code 115, a critical incident is any alleged, suspected, or actual event where there is reason to believe a resident’s health or safety may be harmed. The category is broad on purpose. It includes abuse, neglect, and financial exploitation, and it also covers injuries of known or unknown origin, medical emergencies, unscheduled hospitalizations, missing residents, peer-to-peer aggression, and any incident that brings police or the fire department to the home. When a family learns about an injury days later, or only from a hospital, the first question is whether the provider treated it as a critical incident and documented it the way the rules require.

What does continuous supervision mean in a 24-hour CILA?

Rule 115 defines continuous supervision as care in which an employee is physically present on site during all hours residents are present, unless the Personal Plan and Implementation Strategy say otherwise. Depending on the plan, that presence can range from staying within line of sight to being nearby and available. Intermittent CILAs work differently: staff are on site less than 24 hours a day, with on-call coverage the rest of the time. Comparing the supervision level in the plan with the staffing schedule and shift logs is often how families learn whether a home was short-staffed on the day of the injury.

Questions to ask about a finding

These points apply to any OIG investigation question. Families often ask who was interviewed, whether video or medical records were reviewed, and whether the provider took corrective action afterward. Every family’s situation is different. Some need answers right away; others are still gathering information. A lawyer’s role is to explain the law clearly, protect the resident’s privacy, preserve evidence, and act on the family’s timeline while deadlines are tracked.

Steps families can take today

• Make sure your loved one is safe. If there is immediate danger, call 911. Ask the agency what has changed to protect your loved one while any review is pending.
• Call the OIG hotline at 1-800-368-1463 if you are not sure a report was made. Families can report directly.
• Get medical care documented. Ask for copies of emergency room, clinic, and nursing notes, and keep discharge papers.
• Write a timeline with dates, names of staff, and what each person told you. Memories fade quickly, and details matter later.
• Save messages and photos. Keep texts, emails, voicemails, and photos of injuries, the room, or equipment, if you can do so safely and respectfully.
• Do not sign releases or settlement papers from a provider or insurer before you understand what they cover.

Families do not have to do this alone

Talking with a lawyer is free and does not commit you to anything. Many families first want to understand what happened, whether the provider followed the rules, and how to keep their loved one safe. A lawyer can explain options, request records, and coordinate with a guardian.
