Medical malpractice claims generally require the testimony of an expert witness in order to determine negligence and causation. The testifying expert is crucially important to the presentation of a case, in addition to having the requisite medical credentials and experience to opine on the evidence reviewed. A recent appeals court decision from New Jersey considers whether a treating physician can testify for the defendant. The decision certainly has potential implications for New York medical malpractice law.The defendant performed surgery on the plaintiff to extract an organ by means of a specific, though risky, surgical procedure. The parties agreed that during the surgery, the defendant sliced the incorrect area, causing an injury to the plaintiff. The issue before the court was whether this injury was a risk to which the patient consented prior to surgery, or instead a breach of the defendant’s standard of care.
Several days following the surgery, the plaintiff went back to an emergency room in New York with vomiting symptoms. Another surgeon performed emergency surgery on the plaintiff and discovered that her bile duct had been severed. This surgeon who repaired the bile duct later testified at a deposition that in his opinion, the defendant did not deviate from the standard of care. The plaintiff appealed a lower court ruling, arguing, in part, that the testimony of the operating physician was prejudicial to the plaintiff’s case.
