Facts
- Miklos Arato, a 42-year-old electrical contractor, underwent surgery in 1980 during which a malignant tumor on the tail of his pancreas was discovered and partially removed along with his spleen and a kidney.
- Concerned about recurrence, the surgeon referred Arato to oncologists for chemotherapy and radiation therapy that had shown promise in experimental trials for pancreatic cancer.
- At the initial oncology visit, Arato completed a questionnaire indicating he wanted to be told the truth about his condition.
- The physicians discussed treatment and conveyed generally that most pancreatic cancer patients die of the disease and that recurrence would be considered incurable.
- The physicians did not provide detailed statistical survival rates or specific numerical life-expectancy probabilities.
- Arato later died of pancreatic cancer.
- His wife and other heirs sued the treating physicians, alleging negligence and lack of informed consent based on the asserted failure to disclose statistical life expectancy; they contended he would have declined treatment and used his remaining time differently had he been given such statistics.
- A jury returned a defense verdict after receiving a standard informed-consent instruction and hearing expert testimony on medical practice regarding disclosure of survival statistics.
- The Court of Appeal reversed, concluding the physicians should have disclosed statistical life expectancy and faulting the standard jury instruction.
Issues
- Whether informed consent requires physicians, as a matter of law, to disclose statistical life-expectancy or survival-rate data for pancreatic cancer.
- Whether informed consent obligates physicians to disclose information primarily material to a patient’s nonmedical interests (such as financial planning).
- Whether the standard informed-consent jury instruction adequately states California law.
- Whether expert testimony regarding medical custom on disclosing survival statistics is admissible in evaluating informed-consent disclosures.
Decision
- The California Supreme Court reversed the Court of Appeal and directed affirmance of the defense judgment.
- The Court held there is no categorical legal duty to disclose specific statistical life-expectancy probabilities to obtain informed consent.
- The Court rejected any informed-consent duty to disclose information material solely to nonmedical interests; physicians are not required to serve as financial advisers.
- The Court upheld the standard informed-consent jury instruction as legally adequate.
- The Court approved admission of expert testimony on professional practice regarding disclosure of statistical survival information for the limited purpose of informing whether such disclosure is medically appropriate.
Legal Principles
- A physician must disclose material information needed for a patient to decide whether to undergo a proposed treatment, measured by what a reasonable person in the patient’s position would consider significant.
- The informed-consent duty is directed to medical decision-making about treatment, risks, and alternatives; it does not extend to advising about nonmedical life planning or financial affairs.
- Physicians are not required, as a matter of law, to provide detailed population-based survival statistics in every cancer case; such figures may be unreliable for predicting an individual patient’s outcome.
- A patient’s generalized expression of wanting to “be told the truth” does not, by itself, expand the legal scope of disclosure beyond the material-information standard.
- Expert testimony about medical practice may be admitted to address whether disclosure of specialized statistical information is professionally appropriate, without converting professional custom into the controlling legal standard.
Conclusion
The court reinstated the defense verdict, holding that informed consent required disclosure of material medical information about the proposed cancer treatment but did not impose a per se obligation to provide statistical life-expectancy probabilities or to disclose information aimed primarily at the patient’s nonmedical financial and personal planning.
