Failure to Diagnose Infection Medical Malpractice in Chicago

A doctor who fails to diagnose an infection is not just making a medical mistake, they may be committing medical malpractice. Infections can escalate from manageable to fatal in a matter of hours. When a physician misses the signs, orders the wrong tests, or simply dismisses a patient’s symptoms, the consequences can include sepsis, organ failure, amputation, or death. If you or someone you love suffered serious harm because a doctor failed to identify an infection in time, you have legal rights under Illinois law. The team at Chicago personal injury lawyer Briskman Briskman & Greenberg is here to help you understand those rights and fight for the compensation you deserve.

What Counts as Failure to Diagnose an Infection Under Illinois Law

Failure to diagnose an infection is a form of medical malpractice. It occurs when a healthcare provider does not identify an infection that a competent provider, applying the accepted standard of care, would have caught in time to prevent serious harm.

The standard of care is the benchmark that Illinois courts use to measure a doctor’s conduct. It reflects what a reasonably skilled physician in the same field would do under the same circumstances. When a provider’s actions fall short of that benchmark, and that failure causes injury, it becomes the foundation of a malpractice claim.

Failure to diagnose an infection can take several forms. A doctor may ignore classic warning signs like fever, elevated white blood cell count, or localized swelling. A physician may fail to order a blood culture, urinalysis, or imaging study that would have revealed the infection. Lab results showing infection may go unreviewed or uncommunicated. In some cases, a patient is discharged from an emergency room near Northwestern Memorial Hospital or Stroger Hospital of Cook County without proper follow-up testing, only to return days later in septic shock.

The infection does not have to be exotic or rare. Missed urinary tract infections, untreated wound infections after surgery, undetected bloodstream infections, and overlooked pneumonia all fall into this category. While many infections are routine and treatable with antibiotics or antifungal medications, failure to properly diagnose them can quickly escalate into life-threatening emergencies, and a minor infection can progress to sepsis, septic shock, organ failure, or death if not promptly recognized and treated.

Illinois law does not require a perfect outcome. What it requires is that the provider acted with reasonable skill and care. If they did not, and you were harmed, a malpractice claim may be available to you. Speaking with a medical malpractice lawyer as soon as possible is the best first step.

Common Types of Infections That Are Frequently Missed by Doctors

Certain infections are missed more often than others, either because their symptoms overlap with less serious conditions or because providers fail to order the right diagnostic tests at the right time.

Sepsis is one of the most dangerous and frequently missed infections. It occurs when the body’s response to an infection spirals out of control, attacking its own tissues. Patients presenting with sepsis may show fever, confusion, rapid heart rate, and low blood pressure, but these signs are sometimes attributed to dehydration, anxiety, or other benign causes. Providers must act quickly, particularly in cases where sepsis or meningitis is suspected, and waiting for test results should not delay the initiation of empiric treatment when clinical suspicion is high.

MRSA, or methicillin-resistant Staphylococcus aureus, is another commonly missed infection. It can appear as a skin wound that looks minor but is actually spreading deeper into tissue. Providers who treat it as a routine skin infection without culturing the wound may allow it to become systemic.

Urinary tract infections that spread to the kidneys, called pyelonephritis, are regularly underdiagnosed in elderly patients and in people with diabetes. Meningitis, an infection of the membranes surrounding the brain and spinal cord, is frequently confused with migraines or the flu. Pneumonia is often dismissed as bronchitis, especially when chest X-rays are not ordered or are misread. Post-surgical wound infections are sometimes attributed to normal healing rather than bacterial contamination.

Bloodstream infections, also called bacteremia, can develop from IV lines, catheters, or surgical sites. Patients in ICU settings or long-term care facilities near Chicago’s South Side or in the suburbs along the I-290 corridor face elevated risk. According to the Centers for Disease Control and Prevention, approximately one out of every 25 patients in a hospital setting acquires a healthcare-associated infection. When those infections go undiagnosed, the harm that follows is often preventable.

How Illinois Law Governs Failure to Diagnose Infection Malpractice Claims

Illinois medical malpractice law sets specific requirements that every patient must meet before a case can move forward. Understanding these rules helps you know what to expect and why acting quickly matters.

First, there is the statute of limitations. Under 735 ILCS 5/13-212(a), an Illinois medical malpractice action generally must be brought within two years after the claimant knew, or through reasonable diligence should have known, of the injury or death for which damages are sought, and in most Illinois medical malpractice cases, there is usually a four-year outside limit from the act or omission. Missing this deadline typically means losing your right to sue, regardless of how strong your case is.

For minors, the rules differ. Under 735 ILCS 5/13-212(b), when the person entitled to bring the action was under age 18 when the cause of action accrued, the claim generally may not be brought more than eight years after the act or omission that caused the injury or death, and in no event may the action be brought after the person’s 22nd birthday.

Second, Illinois requires what is called a Certificate of Merit before a malpractice lawsuit can proceed. Under 735 ILCS 5/2-622, the plaintiff’s attorney must attach an affidavit to the complaint declaring that a qualified health professional has reviewed the case, examined the medical records, and determined in a written report that there is a reasonable and meritorious cause for the claim. That reviewing professional must have practiced or taught in the same area of medicine at issue within the last six years.

Third, Illinois does not cap economic or non-economic damages in medical malpractice cases. The Illinois Supreme Court struck down statutory caps on non-economic damages in Lebron v. Gottlieb Memorial Hospital (2010). Under 735 ILCS 5/2-1115, punitive damages are not available in healing art malpractice cases, but compensatory damages for medical expenses, lost wages, and pain and suffering remain fully recoverable.

Under 735 ILCS 5/2-1117, defendants found to be at least 25% at fault are jointly and severally liable for all damages, meaning you may be able to recover your full losses even when multiple providers share responsibility. A skilled medical malpractice attorney can help identify every responsible party.

What You Must Prove to Win a Failure to Diagnose Infection Case in Illinois

Winning a failure to diagnose infection case requires more than showing that a doctor got it wrong. Illinois law requires proof of four specific elements, and each one must be supported by evidence.

The first element is the existence of a doctor-patient relationship. This establishes that the provider owed you a duty of care. If you were treated in an emergency room, clinic, or hospital, this element is usually straightforward to establish.

The second element is a breach of the standard of care. You must show that the provider’s conduct fell below what a reasonably skilled physician in the same specialty would have done. For example, a patient who presents to a Chicago-area urgent care clinic with a high fever, chills, and a recent surgical wound should prompt a provider to order blood cultures and wound cultures. Failure to do so, when a competent provider would have, is a breach.

The third element is causation. You must show that the breach, meaning the failure to diagnose the infection, directly caused your injury. This is often the most contested element. The defense may argue that the infection would have progressed even with timely treatment. Your attorney will work with medical experts to counter that argument with evidence of what proper treatment would have achieved.

The fourth element is damages. You must have suffered actual harm, whether physical, financial, or both. The consequences of failing to diagnose an infection can be catastrophic, and patients may develop widespread sepsis requiring admission to the intensive care unit, intubation, or dialysis, with some survivors facing amputations due to tissue necrosis or permanent organ damage that requires lifelong medical care.

Illinois also requires expert testimony to establish both the standard of care and causation. These experts must be qualified in the relevant area of medicine. Briskman Briskman & Greenberg works with credentialed medical professionals to build the evidentiary foundation your case requires. Our medical malpractice lawyer team understands what it takes to present these cases persuasively.

What Compensation Can You Recover for a Missed Infection Diagnosis in Chicago

Victims of failure to diagnose infection malpractice in Illinois can pursue several categories of compensation, depending on the severity of the harm and how it has affected their lives.

Economic damages cover the financial losses that can be calculated with precision. These include past and future medical expenses, such as ICU stays, surgeries, rehabilitation, dialysis, prosthetics, and long-term care. They also include lost wages and reduced earning capacity if the infection or its complications left you unable to work. A patient who develops sepsis, spends weeks in a hospital like Rush University Medical Center or University of Chicago Medical Center, and requires months of recovery may face hundreds of thousands of dollars in medical bills alone.

Non-economic damages cover the human cost of the injury. Pain and suffering, emotional distress, loss of enjoyment of life, and the impact on personal relationships are all compensable. Illinois does not cap these damages, so the recovery reflects the full extent of your suffering.

When a missed infection diagnosis leads to death, the surviving family members may pursue a wrongful death claim under the Illinois Wrongful Death Act (740 ILCS 180). This allows recovery for grief, loss of companionship, and the financial support the deceased would have provided.

Under 735 ILCS 5/2-1114, attorney’s fees in Illinois medical malpractice cases are capped at 33 and one-third percent of all sums recovered on a contingency fee basis. This means you pay nothing unless your case resolves in your favor. There are no upfront legal fees to work with Briskman Briskman & Greenberg.

FAQs About Failure to Diagnose Infection Medical Malpractice in Chicago

How do I know if a missed infection diagnosis qualifies as medical malpractice in Illinois?

A missed infection diagnosis qualifies as malpractice when a competent provider in the same specialty would have identified the infection in time to prevent your harm, and the failure to do so caused you a serious injury. This requires showing a breach of the standard of care and a direct link between that breach and your damages. Not every missed diagnosis rises to the level of malpractice, which is why Illinois law under 735 ILCS 5/2-622 requires a qualified health professional to review your case and confirm it has merit before a lawsuit can be filed. An attorney can help you get that review done and assess whether you have a viable claim.

What is the deadline for filing a failure to diagnose infection malpractice claim in Illinois?

Under 735 ILCS 5/13-212(a), you generally have two years from the date you knew or reasonably should have known that a healthcare provider’s negligence caused your injury. There is also an absolute four-year deadline from the date the malpractice occurred, regardless of when you discovered the harm. If the patient is a minor, the deadline is extended to eight years from the negligent act, but no later than the patient’s 22nd birthday under 735 ILCS 5/13-212(b). Missing either deadline typically bars your claim entirely, so contacting an attorney as soon as possible is critical.

Can I sue a hospital, not just the doctor, for failing to diagnose my infection?

Yes. Hospitals can be held liable for the negligence of their employed physicians, nurses, and other staff. Even when a doctor is technically an independent contractor, a hospital may still face liability under theories of apparent authority if the patient reasonably believed the doctor was a hospital employee. Under 735 ILCS 5/2-1117, any defendant found to be at least 25% at fault is jointly and severally liable for all damages, which means a hospital and a physician can both be responsible for the full amount of your losses. Identifying all liable parties is one of the most important steps in building a strong case.

What damages can I recover if a doctor failed to diagnose my infection and I developed sepsis?

You can recover economic damages, including all past and future medical expenses, lost wages, and the cost of long-term care or rehabilitation. You can also recover non-economic damages for pain and suffering, emotional distress, and loss of enjoyment of life. Illinois does not cap economic or non-economic damages in medical malpractice cases following the Illinois Supreme Court’s ruling in Lebron v. Gottlieb Memorial Hospital (2010). If the infection caused a loved one’s death, the family may also pursue a wrongful death claim under the Illinois Wrongful Death Act (740 ILCS 180) for loss of companionship and financial support.

Do I need to pay anything upfront to hire Briskman Briskman & Greenberg for a malpractice case?

No. Briskman Briskman & Greenberg handles medical malpractice cases on a contingency fee basis, meaning you pay no attorney’s fees unless your case results in a recovery. Under 735 ILCS 5/2-1114, attorney’s fees in Illinois medical malpractice cases are capped at 33 and one-third percent of the total amount recovered. You will not owe any legal fees out of pocket to get started. Call (312) 222-0010 to schedule a free consultation with our team at 205 W. Randolph St., Suite 925, Chicago, IL 60606.
