A bad outcome is not the same as malpractice. Medicine involves risk, and a complication that was disclosed and properly managed is usually not a case. Malpractice means the care fell below the professional standard — what a reasonably careful provider in the same specialty would have done — and that the failure caused the harm. This page collects every medical negligence guide on this site.
Illinois adds procedural requirements that do not apply to ordinary injury claims. Under 735 ILCS 5/2-622, a malpractice complaint must be filed with an affidavit and a written report from a qualified health professional in the same or a similar specialty confirming there is a reasonable and meritorious basis for the case. That report has to exist before filing, which is why these cases need to be reviewed by an expert months before any deadline.
The deadline itself is a two-part rule under 735 ILCS 5/13-212: two years from when you knew, or reasonably should have known, of the injury and that it was wrongfully caused — but no more than four years from the act itself, regardless of discovery. Children have longer, up to eight years, but not past their 22nd birthday. Claims against public hospitals can run on much shorter clocks.
On damages, Illinois is a claimant-friendly jurisdiction in one important respect: there is no cap on compensatory damages. The 2005 caps were struck down as unconstitutional in Lebron v. Gottlieb Memorial Hospital, 237 Ill. 2d 217 (2010), and no cap has replaced them. Cases commonly involve surgical errors, anaesthesia errors, missed or delayed cancer diagnosis, emergency room failures, birth injuries, hospital-acquired infections, and medication mistakes.
