Q1: What area of law does Matthies v. Mastromonaco primarily address?
Torts—Medical Malpractice (Informed Consent)
Q2: What was the central legal issue in Matthies v. Mastromonaco?
Does the doctrine of informed consent require a physician who recommends conservative, non-surgical treatment to disclose medically reasonable alternative treatments—including surgery and the option of no treatment—and, if so, is the failure to do so actionable in negligence even when no unauthorized touching occurred?
Q3: What rule did the court apply?
New Jersey applies a patient-oriented standard for informed consent. A physician must disclose to the patient all information that a reasonably prudent patient in the plaintiff's position would deem material to an informed decision, including: (1) the nature of the recommended course of treatment; (2) the material risks and benefits of that course; (3) the medically reasonable alternatives (including no treatment), with their material risks and benefits; and (4) the probable outcome of foregoing treatment. Failure to make these disclosures is negligence, not battery (which is reserved for unauthorized touching). To prevail, a plaintiff must prove: (a) breach—non-disclosure of material information regarding medically reasonable alternatives; (b) causation—an objective test that a reasonably prudent patient in the plaintiff's position would have chosen a different course if properly informed; and (c) injury—that the different choice would have yielded a better outcome. Expert testimony is ordinarily required to establish which alternatives were medically reasonable and to explain their comparative risks and benefits.
Q4: What was the court's holding?
Yes. The doctrine of informed consent requires disclosure of medically reasonable alternatives to the recommended treatment, including surgery and no treatment, even when the physician advocates conservative care. The failure to disclose such alternatives sounds in negligence rather than battery. The court reversed and remanded for a new trial on the informed-consent claim under the proper legal standard.
Q5: Why is Matthies v. Mastromonaco significant?
Matthies broadens informed-consent doctrine to require disclosure of medically reasonable alternatives regardless of whether the physician recommends or will perform them, firmly situates nondisclosure as negligence rather than battery, and articulates clear elements and evidentiary needs. For students and practitioners, it is a key case on: the patient-centered materiality standard; the duty to discuss alternatives and the option of no treatment; the objective causation test; the role of expert testimony; and the distinction between lack of consent (battery) and lack of informed consent (negligence).
