Victims of medical negligence can recover damages for reduced chance of survival even if the patient’s prospect for recovery was already less than 50 percent, Massachusetts highest court ruled this week. The Massachusetts Supreme Judicial Court decision stemmed from a $1 million award to the estate of a man whose doctor failed to diagnose his stomach cancer.
“Where a physician’s negligence reduces or eliminates the patient’s prospects for achieving a more favorable medical outcome, the physician has harmed the patient and is liable for damages,” the court said in a decision written by Chief Justice Margaret Marshall.
The SJC recognized for the first time a doctrine known in medical malpractice cases as “loss of chance,” which allows a patient whose odds of recovery are 50 percent or less to receive damages for any negligence that reduced those odds. The court established a formula for juries to award damages proportionate to the reduced survival rate caused by the doctor’s negligence which will require the fact finder to undertake the following calculations:
(1) The fact finder must first calculate the total amount of damages allowable for the death under the wrongful death statute, G.L. c. 229, § 2, or, in the case of medical malpractice not resulting in death, the full amount of damages allowable for the injury. This is the amount to which the decedent would be entitled if the case were not a loss of chance case: the full amount of compensation for the decedent’s death or injury. [FN42]
(2) The fact finder must next calculate the patient’s chance of survival or cure immediately preceding (“but for”) the medical malpractice.
(3) The fact finder must then calculate the chance of survival or cure that the patient had as a result of the medical malpractice.
(4) The fact finder must then subtract the amount derived in step 3 from the amount derived in step 2.
(5) The fact finder must then multiply the amount determined in step 1 by the percentage calculated in step 4 to derive the proportional damages award for loss of chance.
To illustrate, suppose in a wrongful death case that a jury found, based on expert testimony and the facts of the case, that full wrongful death damages would be $600,000 (step 1), that the patient had a 45% chance of survival prior to the medical malpractice (step 2), and that the physician’s tortious acts reduced the chances of survival to 15% (step 3). The patient’s chances of survival were reduced 30% (i.e., 45% minus 15%) due to the physician’s malpractice (step 4), and the patient’s loss of chance damages would be $600,000 multiplied by 30%, for a total of $180,000 (step 5).
Expert testimony is required to ascertain what measure of a more favorable outcome is medically appropriate (for example, five-year survival as in this case), to determine what statistical rates of survival apply in what circumstances, for example, a 37.5% chance of survival, and to apply these rates to the particular clinical circumstances of the patient.
