The Illinois Appellate Court recently upheld a medical malpractice judgment against Dr. Eugene Muzykansky and Adult Primary Care Center, Ltd., in a case concerning the wrongful death of Patricia Kos. The court's decision, filed on July 31, 2026, affects not only the defendants but also sets a precedent for how medical malpractice cases are handled in Illinois.
The case originated when Todd Kos filed a wrongful death and survival action against the defendants after his mother, Patricia Kos, died at the age of 67. The plaintiff claimed that the defendants committed medical malpractice, leading to his mother’s untimely death. This case highlights the critical importance of proper medical assessment and timely intervention in healthcare.
In July 2015, Todd Kos noticed that his mother was unwell, experiencing stomach pains and bloody diarrhea. After a visit to Dr. Muzykansky, she was prescribed hemorrhoid cream and advised to take Imodium. However, her condition worsened, and she ultimately died from a gastrointestinal hemorrhage caused by an undiagnosed duodenal ulcer that had formed due to cancer. The case reached the appellate court after the jury ruled in favor of Todd Kos, leading the defendants to appeal the decision.
The Appellate Court, led by Presiding Justice Mitchell, affirmed the lower court's ruling, rejecting the defendants' claims that there were fatal gaps in the plaintiff's case regarding proximate cause. The court found that the plaintiff had sufficiently established a causal link between the defendants' negligence and the death of Patricia Kos. According to the opinion, "It was obvious that she was bleeding. She was losing weight. She had a process that was not fully explained on the exam that needed to be evaluated either that day or sometime sooner than that." This statement underscored the court’s view that a reasonable physician should have recognized the urgency of the situation.
The court also addressed the defendants' arguments concerning the need for expert testimony from a gastroenterologist. It stated that the absence of such testimony did not undermine the plaintiff's case, as the surgical oncologist provided sufficient evidence on how the bleed would have been treated had the patient been sent to the hospital. The court ruled, "Plaintiff did not fail to establish a prima facie case on proximate cause," reinforcing the idea that a medical professional's failure to act can lead to dire consequences.
The ruling has significant implications for future medical malpractice cases in Illinois. It emphasizes the necessity for medical professionals to thoroughly assess their patients and act promptly when faced with serious symptoms. The decision also highlights the importance of expert testimony in establishing causation in medical malpractice cases, though it clarifies that not all expert testimony must come from the same field of medicine.
Moving forward, the ruling may influence how medical malpractice cases are prosecuted in Illinois, particularly in terms of the standards of care expected from medical professionals. It sets a precedent that reinforces the accountability of healthcare providers in ensuring patient safety and timely medical intervention.
As for the defendants, they may consider appealing the decision to the Illinois Supreme Court. However, it remains unclear if there are any related cases pending that could affect this ruling. The outcome of this case serves as a reminder of the critical role that timely medical care plays in patient outcomes and the legal responsibilities of healthcare providers.
