The "error in judgment" rule in Tennessee medical malpractice cases is perhaps the most unfair principle of the common law of torts. The rule was conceived in recognition of the fact that there may be more than one right way to approach a medical issue – the "two schools of thought" principle. This narrow application of the rule makes sense. For example, in most cases, a surgeon can do a cervical laminectomy utilizing a posterior approach or an anterior approach. Both carry certain risks and have certain benefits, but as long as informed consent is obtained and both approaches are reasonable for that patient, a surgeon should not be held accountable for doing one approach rather than the other.
But the error in judgment rule has been bastardized to give it the potential to gut most medical malpractice claims in Tennessee. Here is the jury charge on the subject in Tennessee:
By undertaking treatment a physician does not guarantee a good result. A physician is not negligent merely because of an unsuccessful result or an error in judgment. An injury alone does not raise a presumption of the physician’s negligence. It is negligence, however, if the error of judgment or lack of success is due to a failure to have and use the required knowledge, care and skill as defined in these instructions.
