7. Professor Paul Lombardo (Director of the Program in Law and Medicine, University of Virginia, Center for Biomedical Ethics) has reconstructed the story surrounding Mary Schloendorff's case. Paul A. Lombardo, Phantom tumors and hysterical women: Revising our view of the Schloendorff case, 33 Journal of Law, Medicine & Ethics 791 (2005). The story of the Schloendorff case, related below, relies on Lombardo's account.

8. Despite Cardozo's declarations about the right of patients to refuse care, Schloendorff ultimately lost the case because the court concluded that the hospital was protected by the doctrine of charitable immunity from tort liability. 105 North Eastern Reporter at 95.

9. Assault and battery cases may differ from informed consent cases. There may be a different assessment of damages, different elements of proof may be relevant, and the statute of limitations may differ. Mark Fowler, Note, Appointing an Agent to Make Medical Treatment Choices, 84 Columbia Law Review 985, 989 n.21 (1984). In New York, informed consent cases are classed along with medical malpractice cases and, thus, like medical malpractice cases, “must be commenced within 2 years and 6 months of the act giving rise to the cause of action.” Allan Schwartz, Assault – Civil Aspects, 6A New York Jurisprudence 2nd, Assault, Section 19 (Statute of Limitations) (2006). Schwarz notes, however that “[w]here a patient suffers injury as a result of a medical operation performed contrary to the patient's instructions … such an operation has been held to constitute a trespass upon the body and the basis for an action in assault. In such a case, the 1-year statute of limitations [of assault and battery cases] applies.” Id.

10. E. Haavi Morreim, Medial Research Litigation and Malpractice Tort Doctrines, 4 Houston Journal of Health Law & Policy 1, 53–54 (2003). Morreim notes as well that consent cases brought through a battery cause-of-action may involve accusing the physician of a crime or, at least, of an intentional tort. Moreover, battery claims open physician–defendants to punitive damages. Id.

11. Schloendorff v. N.Y. Hospital is illustrative. Mary Schloendorff consented to an ether exam but not to removal of her uterus.

12. This second condition may involve surgery on the wrong body part (e.g., one limb instead of the other) or the “substitution of one treatment for another.” E. Haavi Morreim, Medical Research Litigation and Malpractice Tort Doctrines, 4 Houston Journal of Health Law & Policy 1, 58 (2003).

13. See, e.g., Pugsley v. Privette, 263 South Eastern Reporter 2nd 69 (Virginia 1980) (state supreme court affirmed jury award of damages in battery against an obstetrician who treated a patient who had given consent to be treated by a different physician). The state supreme court explained:

20. Cobbs v. Grant, 8 California Reports 3rd 229 (1972).

21. This section describes the development and legal rules underlying the informed consent doctrine through reference to the D.C. case, Canterbury v. Spence, 464 Federal Reporter 2nd series 772 (United States Court of Appeals for the District of Columbia 1972).

22. A more detailed account of these changes can be found in Janet L. Dolgin, The Evolution of the “Patient”: Shifts in Attitudes About Consent, Genetic Information, and Commercialization in Health Care, 34 Hofstra Law Review 137 (2005).

23. See, e.g., Milton C. Regan, Jr., Family Law and the Pursuit of Intimacy 6, 9–10 (New York University Press 1993).

24. This form of relationship between patient and doctor is described more fully in Janet L. Dolgin, Debating Conflicts: Medicine, Commerce, and Contrasting Ethical Orders, 35 Hofstra Law Review 705 (2006).

25. These changes, including the creation of Medicare and Medicaid, the soaring costs of healthcare, the consequent advent of managed care, and the technological developments of the late 20th and early 21st centuries have been widely documented. See, e.g., Roy Porter, ed., The Cambridge History of Medicine (Cambridge University Press 2006); Paul Starr, The Social Transformation of Medicine (Basic Books 1982).

28. Canterbury v. Spence, 464 Federal Reporter 2nd series 772 (United States Court of Appeals for the District of Columbia 1972).

29. This information was actually conveyed to Jerry Canterbury's mother, described by the court as a “poor widow” “who lived in West Virginia and could be reached through a neighbor's phone.” Canterbury's mother signed a consent form, but only after the surgery had been performed. There was contradictory testimony about whether she had consented orally before the surgery.

30. 464 Federal Reporter 2nd series at 778.

31. A fall immediately after the surgery resulted in paralysis from the waist down. Dr. Spence performed a second operation at that time. The court explained that after the second operation Canterbury's “control over his muscles improved somewhat.”

32. The trial court concluded that Canterbury “had failed to produce any medical evidence indicating negligence on Dr. Spence's part in diagnosing appellant's malady or in performing the laminectomy.” 464 Federal Reporter 2nd series at 778. The trial court judge did not refer to the physician's failure to “divulge the possible consequences of the laminectomy.” Id. at 779. One commentator suggested that the absence of evidence as to physician and hospital negligence was “inexplicable, … save an inability to secure any expert witness willing to bridge the community of silence to testify against one of their own.” Emmanuel O. Iheukwumere, Doctor, Are You Experienced?: The Relevance of Disclosure of Physician Experience to a Valid Informed Consent, 18 Journal of Contemporary Health Law & Policy 373, 389 (2002).

33. 464 Federal Reporter 2nd series at 788.

34. Canterbury, 464 Federal Reporter 2nd series at 787. The court noted: “In broad outline, we agree that ‘[a] risk is thus material when a reasonable person, in what the physician knows or should know to be the patient's position, would be likely to attach significance to the risk or cluster of risks in deciding whether or not to forego the proposed therapy.’“ Id. at 787 (quoting Jon R. Waltz & Thomas W. Scheuneman, Informed Consent to Therapy, 64 Northwestern University Law Review 628, 640 (1970)).

In contrast to the usual rule, the Supreme Court of Oklahoma adopted a subjective standard that looked not to what a reasonable person would find material but to what a particular patient would find material. Scott v. Bradford, 606 Pacific Reporter 2nd 554, 559 (Oklahoma 1979). The court explained that the Canterbury court's approach could be criticized for

Id. at 559.

35. New York's statute provides:

N.Y. Public Health Law, Section 2805-d (2) (2006). Thus the statute looks to practice among other healthcare providers but precludes courts’ relying on a standard of practice that provides almost no information; that preclusion is accomplished with the phrase “in a manner permitting the patient to make a knowledgeable evaluation.” Id. The statute further requires the plaintiff to show that

38. AMA, Code of Medical Ethics, Principle 8.08; available at http://www.ama-assn.org/apps/pf_new/pf_online (last accessed 11 Dec 2006). In Culbertson v. Mernitz, 602 North Eastern Reporter 2nd 98 (1992), the Indiana Supreme Court noted this shift within the profession between the early 1970s, when Canterbury was decided, and 1992 (when Culbertson was decided). By 1992, the court reported patients did not need to fear that the “reasonably prudent physician standard” would “destroy[] the patient's right of self-decision.” Id. at 103. In supporting this assertion, the court referred to the incorporation of the informed consent rule in the AMA's Code of Medical Ethics. Id.

39. NY Public Health Law, Sec. 2805-d(1) (2006).

40. See, e.g., Truman v. Thomas, 611 Pacific Reporter 2nd 902 (Supreme Court of California 1980) (requiring disclosure of information about reasons to have a pap smear); Gates v. Jensen, 595 Pacific Reporter 2nd 919 (Supreme Court of Washington 1979) (requiring that information about glaucoma tests be communicated to patient with symptoms).

41. Truman v. Thomas, 611 Pacific Reporter 2nd 902, 906 (Supreme Court of California 1980). The California court explained that Mrs. Truman had apparently refused the test because of the cost involved or because she did not “feel like it.” Furthermore, there was no evidence that she understood the danger of refusing the test. The court thus concluded:

44. New York law, for example, delineates four exceptions to the informed consent requirement. These include an exception for a commonly known risk (Section 2805-d(4)(a)), for a patient who proclaimed his or her willingness to proceed with treatment regardless of the risk involved or who “assured” the healthcare provider that he or she did not want to be informed of risks (Section 2805-d(4)(b)), cases in which “consent by or on behalf of the patient was not reasonably possible (Section 2805-d(4)(c)), and cases in which the healthcare provider concludes that disclosure “could reasonably be expected to adversely and substantially affect the patient's condition” (Section 2805-d(4)(d)).

45. A Pennsylvania court concluded that a patient may waive the right to information about a proposed form of care, and that if the patient waives that right, the physician need not communicate relevant information. Stover v. Association of Thoracic and Cardiovascular Surgeons, 635 Atlantic Reporter 2nd 47 (Pennsylvania Superior Court 1993). Stover involved a plaintiff who suffered complications after heart value surgery. She sued the surgeon group responsible for her care. The court held for the patient because the defendants were not able adequately to demonstrate that the plaintiff–patient had indeed waived the right to receive information about the surgery and its risks. The court explained: “There is nothing in the record indicating that appellee stated anything resembling ‘I don't want to hear anything about the operation,’ or ‘Stop! You've told me enough. I'll leave it up to you.’ We find no merit to this last of appellants' arguments.” Id. at 1056.

46. The therapeutic exception is one of two exceptions noted in Canterbury. The other is the emergency exception. 464 Federal Reporter Second Series at 789.

47. See, e.g., N.Y. Public Health Law, Section 2805-d(4)(d) (2006).

48. In Canterbury v. Spence, 464 Federal Reporter 2nd series 776 (1972), Judge Robinson acknowledged the “therapeutic” exception, but explained that it should be used only with care because “otherwise it might devour the disclosure rule itself.” He continued: “The privilege does not accept the paternalistic notion that the physician may remain silent simply because divulgence might prompt the patient to forego therapy the physician feels the patient really needs.” 464 Federal Reporter 2nd series at 789.

49. Alan Meisel and Loren Roth concluded from their study of the informed consent rules in clinical settings that often the doctrine as viewed by lawmakers does not harmonize with what occurs in fact:

Alan Meisel & Loren H. Roth, Toward an Informed Discussion of Informed Consent: A Review and Critique of the Empirical Studies, 25 Arizona Law Review 265, 334 (1983).

50. See, e.g., Cobbs v. Grant, 502 Pacific Reporter 2nd 1 (Supreme Court of California 1972).

51. 545 North Western Reporter 2nd 495 (Supreme Court of Wisconsin 1996).

52. The case is unusual for a number of reasons. Among other things, Dr. Kokemoor had informed the patient that the risk of death or disability was about 2%. He also explained that the risk of the procedure he proposed (operating on a basilar, bifurcation aneurysm) was comparable to that of “routine procedures such as tonsillectomies, appendectomies and gall bladder surgeries.” In fact, the court explained,

Id. at 506. Although the court's decision was not premised on a cause-of-action in deceit or fraud, the court was clearly troubled by the doctor's apparent exaggerations and falsifications. Wisconsin's highest court remanded the case to the trial court. The parties settled before the case was retried. See Aaron D. Twerski & Neil B. Cohen, The Second Revolution in Informed Consent: Comparing Physicians to Each Other, 94 Northwestern University Law Review 1, 8 (1999).

53. Some commentators have viewed the decision in Kokemoor as primarily a response to a doctor's misrepresentation of his or her qualifications and skills rather than as a broad rule proclaiming that physicians should provide their patients with provider-specific information as part of the informed consent process. See, e.g., Heyward H. Bouknight, III, Note, Between the Scalpel and the Lie: Comparing Theories of Physician Accountability for Misrepresentations of Experience and Competence, 60 Washington & Lee Law Review 1515, 1530 (2003) (describing the case to be about “a doctor's deceitful responses to patient inquiries”). It should, however, be noted that the court did not expressly predicate its decision on inaccurate responses by the doctor to the patient’s questions.

57. In some states (e.g., Pennsylvania, see Duttry v. Patterson, 771 Atlantic Reporter 2nd 1255 (Supreme Court of Pennsylvania 2001)), physicians, though precluded, of course, from providing patients with false information, are not required to answer such questions.

59. See Kaskie v. Wright, 589 Atlantic Reporter 2nd 213, 217 (Pennsylvania Superior Court 1991). Kaskie was decided 5 years before Kokemoor, but expressly considered and rejected the rule on which the court in Kokemoor relied. See, generally, Mark Hall, Caring, Curing, and Trust: A Response to Gatter, 39 Wake Forest Law Review 447, 450 (2004).

60. See, e.g., Albany Urology Clinic, P.C. v. Cleveland, 528 South Eastern Reporter 2nd 777 (Supreme Court of Georgia 2000) (reversing appellate court decision that doctor was obliged to disclose his cocaine use to his patients); Whiteside v. Lukson, 947 Pacific Reporter 2nd 1263 (Washington Court of Appeals 1997) (holding that surgeon was not obliged to inform patient of his inexperience performing laparoscopic cholecystectomy procedure).
