Kurz v. St. Francis Hospital
The defendants moved to preclude plaintiffs' expert testimony on causation or, alternatively, for a pretrial hearing regarding the plaintiff's vision loss. The plaintiff developed visual disturbances shortly after receiving Amiodarone intravenously following cardiac bypass surgery in 2008. Defendants argued a lack of scientific evidence linking short-term Amiodarone use to optic neuropathy, while the plaintiff's expert contended that rapid drug absorption could cause optic disc edema, a known side effect. Furthermore, the plaintiff highlighted medical records where defendant physicians themselves initially attributed the vision loss to the medication. The court, applying the Frye standard, determined that general causation—Amiodarone causing vision loss—is an established medical theory. It further ruled that the specific causation tests from Parker and Cornell, typically applied to toxic tort cases, were not strictly applicable here due to the distinct nature of medical malpractice. Consequently, the court denied the defendants' motion, finding an adequate foundation for the admissibility of the plaintiff's expert testimony, with any disputes regarding specific timing affecting only the weight of the evidence, not its admissibility.
