When most people think of medical malpractice, they picture dramatic operating room disasters. But the most common examples of malpractice are quieter, more routine failures that happen every day in hospitals and clinics across Illinois. Here are the ones I see most often in my practice.
Failure to diagnose cancer is probably the most heartbreaking category. A patient presents with symptoms. The doctor orders basic tests but does not follow up on abnormal results. Or the radiologist misreads the imaging and calls a tumor benign when it is malignant. Or the primary care doctor dismisses the patient's concerns for months while the cancer advances from stage one to stage three. The delay does not cause the cancer, but it causes the loss of treatment options and the reduction in survival odds. That loss is compensable under Illinois law.
Surgical errors beyond the dramatic wrong-site cases include nerve damage during routine procedures, perforated organs during laparoscopic surgery, inadequate hemostasis leading to post-operative bleeding, and failure to recognize and repair damage to adjacent structures. These errors often do not become apparent until the patient is in the recovery room or back home, which makes timely documentation critical.
Medication errors in hospital settings happen more frequently than most patients realize. Wrong medication administered, wrong dosage, wrong route of administration, medication given to the wrong patient, dangerous drug interactions that the prescribing physician should have caught. Electronic health records are supposed to flag interactions, but the alerts are often overridden by busy physicians. When a medication error causes harm, the prescribing physician, the pharmacy, and the administering nurse can all be liable.
Failure to monitor patients after procedures is a growing category as hospitals push to discharge patients faster. A patient undergoes a procedure that requires close monitoring of vital signs, neurological status, or wound drainage. The nursing staff is stretched thin and the monitoring does not happen at the required intervals. By the time someone checks on the patient, a complication that could have been caught and treated early has progressed to a life-threatening emergency.
Birth injuries during labor and delivery are among the highest-value malpractice cases because the injuries are often permanent and the victim, the baby, has an entire lifetime of medical needs ahead. Failure to monitor fetal heart tones, failure to recognize fetal distress and order a timely C-section, improper use of forceps or vacuum extractors, excessive force during delivery, all of these can result in brachial plexus injuries, cerebral palsy, or hypoxic brain injury.
If any of these scenarios sounds familiar, call me at 312-500-4500. I will review the records for free and tell you whether you have a case.

The most common examples include misdiagnosis or delayed diagnosis (especially of cancer, heart attacks, and strokes), surgical errors (wrong-site surgery, nerve damage, retained instruments), medication errors (wrong drug, wrong dose, dangerous interactions), birth injuries (cerebral palsy, Erb's palsy, oxygen deprivation), anesthesia errors, failure to order appropriate tests, and hospital-acquired infections from poor sanitation.
No. Medicine involves risk, and not every bad outcome is malpractice. Malpractice occurs when a healthcare provider deviates from the accepted standard of care — meaning they did something a reasonably competent doctor in the same specialty would not have done, or failed to do something they should have done — and that deviation caused harm. A bad outcome from a properly performed procedure is not malpractice.
Yes, in many cases. If the doctor is an employee of the hospital, the hospital is liable under the doctrine of respondeat superior. Even if the doctor is an independent contractor, the hospital can be liable under 'apparent agency' if you reasonably believed the doctor was a hospital employee. Hospitals can also be directly liable for negligent credentialing, understaffing, or systemic failures.
A mistake qualifies as malpractice if it represents a deviation from the standard of care that a competent physician in the same specialty would have followed, and if that deviation caused you measurable harm. This determination requires review by a medical expert in the same specialty. Under Illinois law, you need a certificate of merit from such an expert before filing suit.
