Mackowska vs. Sullivan


The plaintiff in this newly filed lawsuit entered an emergency room for treatment and later believed that what he received was substandard. Many accidents happen the ER because of either incompetence or accident and it is important to figure which is the case if you are the victim. Here, the plaintiff claims that his treating providers did not identify what was wrong with him and that this hurt him further.

Filed: June 27, 2016

Jurisdiction: Circuit Court of Illinois, Cook County

Category: Medical Malpractice

Plaintiff: Slywia Mackowska

Defendant(s): Daniel Sullivan; Northwest Orthopaedic Associates; Diagnostic Imaging Associates; et al.


This case presents as a classic medical malpractice, emergency room complaint. A young child goes into the hospital room complaining of a bruised arm, the doctor diagnoses it as broken or in some other trivial manner, sends the child home, but fails to identify and treat some larger issue within the patient. This is what the plaintiff (representing the minor victim) is arguing here and is bringing in a number of parties to be held responsible for the damages that resulted. Some of the defendants include the doctor, doctor’s employer, health care facility, and diagnostic and screening company. Obviously, there could be more than one party at fault in this scenario but because of Illinois’ joint and severability laws the plaintiff only has to get one of them on the hook to get the entire amount of damages.

Claims and Damages:

Here are the bulk of the claims that the plaintiff presented against most of the defendants including the physician, neonatologist, and healthcare facility:

  • They did not properly interpret X-ray;
  • They did not do a sufficient examination to determine the extent of his injuries;
  • They did not refer him to the proper specialist; and
  • They did not properly treat his arm.

The plaintiff also sued the diagnostic company using the following argument:

  • It did not properly perform radiological testing;
  • It did not properly interpret the radiological testing results; and

Finally, here are the damages that the plaintiff claimed in her lawsuit:

  • Pecuniary losses
  • Personal injuries

Expert Insights:

  • Emergency room cases normally provide many opportunities to challenge the quality of care because in the fast action of the medical environment mistakes can be made.
  • In order to challenge the care in this suit, the plaintiff’s counsel must check exactly what the defendants did in order to diagnose the plaintiff and then compare that to the norm of the relevant medical community. This will illustrate whether or not the doctor was operating within the proper standard of care.
  • Awards for misdiagnosis across Illinois and even the nation drastically increase if the plaintiff points to some tangible long-term loss and not mere increased short-term pain.

Client Reviews
Jonathan Rosenfeld was professionally objective, timely, and knowledgeable. Also, his advice was extremely effective regarding my case. In addition, Jonathan was understanding and patient pertaining to any of my questions or concerns. I was very happy with the end result and I highly recommend Jonathan Rosenfeld. Michonne Proulx
Extremely impressed with this law firm. They took control of a bad motorcycle crash that left my uncle seriously injured. Without any guarantee of a financial recovery, they went out and hired accident investigators and engineers to help prove how the accident happened. I am grateful that they worked on a contingency fee basis as there was no way we could have paid for these services on our own. Ethan Armstrong
This lawyer really helped me get compensation for my motorcycle accident case. I know there is no way that I could have gotten anywhere near the amount that Mr. Rosenfeld was able to get to settle my case. Thank you. Daniel Kaim
Jonathan helped my family heal and get compensation after our child was suffered a life threatening injury at daycare. He was sympathetic and in constant contact with us letting us know all he knew every step of the way. We were so blessed to find Jonathan! Giulia
Jonathan did a great job helping my family navigate through a lengthy lawsuit involving my grandmother's death in a nursing home. Through every step of the case, Jonathan kept my family informed of the progression of the case. Although our case eventually settled at a mediation, I really was impressed at how well prepared Jonathan was to take the case to trial. Lisa
