A patient may sue a physician for negligently recommending a course of treatment if (1) that course stems from a misdiagnosis of the patient’s underlying medical condition, or (2) all reasonable physicians in the relevant medical community would agree that the probable risks of that treatment outweigh its probable benefits. The patient’s informed consent to the treatment does not absolve the physician if the patient otherwise has a viable claim for negligently recommending a course of treatment. Here, the trial court wrongly instructed the jury to find for the physician if it found plaintiff had given her informed consent to the treatment, but the error was not prejudicial since the negligent recommendation of treatment should never have gone to the jury anyway since there was no substantial evidence to show that the defendant misdiagnosed plaintiff’s condition or that the treatment he recommended would not have been recommended by other reasonable physicians in the medical community.
