How IDPH Investigations Affect CNAs

If IDPH receives a complaint about a CNA, the investigation process includes:

  1. Intake — Complaint is received via hotline, mail, or facility report
  2. Investigation — IDPH investigator interviews witnesses, reviews records, and examines evidence
  3. Findings — IDPH determines if the allegation is substantiated or unsubstantiated
  4. Notification — The CNA is notified of findings in writing
  5. Registry Notation — If substantiated, a finding is placed on the CNA's HCWR record
  6. Appeal — CNAs have the right to appeal findings through an administrative hearing

A substantiated finding of abuse, neglect, or misappropriation permanently bars you from working as a CNA in Illinois and in any state that checks the registry.
