The Texas Court of Appeals recently ruled in favor of a family suing a nurse practitioner for negligence related to the care of a patient who developed severe health complications. The court's decision, issued on May 28, 2026, affects the ongoing legal battle between Hee-Sook Cheon, NP, and Scott Knowles, who is representing the estate of his late mother, Carolyn Marie Knowles. This ruling is significant as it addresses the standards for medical expert reports in health care liability claims under the Texas Medical Liability Act (TMLA).
The case, Hee-Sook Cheon, NP v. Scott Knowles, Individually and as Personal Representative of the Estate of Carolyn Marie Knowles, was filed under docket number 01-24-00681-CV. It centers on the care provided to Carolyn during her hospitalization, which ultimately led to her death from sepsis. The court's ruling clarifies the requirements for expert reports in medical malpractice cases and the implications for health care providers.
Background
Scott Knowles filed a lawsuit against several health care providers, including Hee-Sook Cheon, after his mother, Carolyn, suffered from pressure ulcers during her hospital stay and later died from complications related to those injuries. Carolyn was initially admitted to HCA Houston Healthcare Northwest for various medical issues, including heart failure and a blood clot. She was later transferred to Encompass Health Rehabilitation Hospital, where her condition worsened.
After being transferred to Crimson Heights Health and Wellness, Carolyn's health deteriorated further. Knowles discovered that Carolyn was lethargic and confused, leading to her transfer to another hospital. Upon arrival, she was found to have severe wounds and signs of sepsis. Knowles subsequently filed a negligence claim against Cheon, arguing that her failure to provide appropriate care contributed to his mother's death.
The Ruling
The Texas Court of Appeals ruled that the expert report submitted by Knowles was adequate to satisfy the requirements of the TMLA. The court affirmed the trial court's decision to deny Cheon's motion to dismiss the claim against her. The opinion stated, "We conclude that the expert report is sufficient to satisfy the TMLA. Therefore, we affirm the trial court’s denial of the motion to dismiss the claim." Chief Justice Terry Adams led the panel that made this ruling.
The court's decision emphasized that the expert report, authored by Dr. Rabee Korbaj, met the necessary criteria by outlining the standard of care, the breach of that standard, and the causation linking Cheon's actions to Carolyn's injuries. The court noted that the report provided a fair summary of the expert's opinions regarding the care that should have been provided.
Impact
This ruling has important implications for health care providers and the legal standards surrounding medical malpractice claims in Texas. By affirming the trial court's decision, the court reinforced the notion that expert reports must adequately address the standard of care, breach, and causation but are not required to provide exhaustive detail at this early stage of litigation.
The decision may encourage families seeking justice for medical negligence to pursue claims, knowing that their expert reports do not need to be perfect but must sufficiently inform the defendant of the claims against them. This ruling could also impact how health care providers prepare for potential litigation, as they may need to ensure their documentation and care practices are more robust to avoid similar claims.
What's Next
Following this ruling, Cheon may choose to appeal the decision to a higher court. However, the court filing did not provide details on whether an appeal is planned. The case will continue as Knowles seeks to hold Cheon accountable for her alleged negligence in his mother's care.
