In traditional Maryland medical malpractice cases, the plaintiff is required to show proximate cause. This involves showing that the medical professional’s actions more likely than not caused the patient’s harm. The loss of chance doctrine is a legal principle that allows a plaintiff to obtain damages from a defendant for a heightened risk of death or injury, even if the plaintiff cannot show by a preponderance of the evidence that the ultimate injury was caused by the defendant’s negligence.
The loss of chance doctrine signifies a change in the traditional rule that health care providers are not liable for providing negligent care if a negative outcome is likely even with good care. Consider the fact that in some situations, a death due to a pre-existing condition may be probable whether or not a particular treatment is correctly done. For example, a person who is suffering from a serious illness may undergo a medical procedure that his or her physician performs negligently, as a result of which the person’s chance of survival is lowered by a certain percentage, and the person subsequently dies. Under the doctrine, the deprived chance of survival or the lost chance of the better outcome is the compensable injury.
