Case History

Jefferson ex rel. Jefferson v. Missouri Baptist Medical Center, 447 S.W.3d 701 (Mo. App. E.D. 2014) — Crystal Jefferson left behind two small children when she died of Stage 4 colon cancer at the age of 37.  Five years before, a CT Scan had allegedly been misread by a radiologist resulting in delayed diagnosis and treatment.  The hospital that provided privileges to the radiologist was granted summary judgment before trial based on a Missouri statute that had been revised during the state’s 2005 tort reform legislation to absolve hospitals for the liability of anyone other than its “employee.”  Ms. Gunn appealed the decision to the Missouri Court of Appeals arguing that whether someone is an “employee” of the hospital is a matter for the jury to determine.  The Court of Appeals reversed adopting Ms. Gunn’s argument and holding that employment is a jury question, essentially returning agency law to its former application in the doctor, hospital setting. 
Duragesic Fentanyl Patch

A thirty five year old gentleman applied a Duragesic Fentanyl Patch as his doctor had recommended shortly before going to bed. He never woke up.  Autopsy and toxicology revealed a lethal dose of Fentanyl in his blood and its only source, the Fentanyl Patch.  This matter came into Ms. Gunn’s office as a medical negligence case, but her research showed a growing number of similar cases involving the Fentanyl Patch.  This same product had been recalled in February, 2004 due to reports of leaking patches from the field.  As a result of the recall, changes were made to the manufacturing process, but the design stayed the same.  The family alleged that not 100% of leaks could be ruled out despite the manufacturing changes or despite quality assurance and quality control measures.  Recalls continued after this death and in the summer of 2009, the company changed from the reservoir design to a matrix design, which does not leak. This matter resolved a short time thereafter.

Youth Football Helmet — An eighteen year old player for Pop Warner collided head to head with a teammate while wearing a youth football helmet. The collision resulted in a subdural hematoma and permanent brain damage.  Discovery revealed that the helmet provided less than adequate protection for a simple youth football maneuver.  Other similar incidents were also uncovered revealing numerous like injuries.  The case was resolved shortly prior to trial.
