group of practitioners would not qualify. The medical malpractice plaintiff must establish the appropriate standard of care and demonstrate that the standard of care has been breached, with expert testimony. 3. A physician also has a "duty to inform" a patient of any material risks or fiduciary interests of the physician that might cause the patient to reconsider a procedure, and may be liable if injury occurs due to the undisclosed risk, and the patient can prove that if he had been informed he would not have gone through with the procedure, without benefit of hindsight. (Informed Consent Rule.) Full disclosure of all material risks incident to treatment must be fully disclosed, unless doing so would impair urgent treatment. As it relates to mental health professionals standard of care, the California Supreme Court, held that these professionals have "duty to protect" individuals who are specifically threatened by a patient. [Tarasoff v. Regents of the University of California, 17 Cal. 3d 425, 551 P.2d 334, 131 Cal. Rptr. 14 (Cal. 1976)]. 4. A recipient of pro bono (free) services (either legal or medical) is entitled to expect the same standard of care as a person who pays for the same services, to prevent an indigent person from being entitled to only substandard care. Medical standards of care exist for many conditions, including diabetes, some cancers, and sexual abuse. Failure to provide patients treatment that meets a standard of care can incur legal liability for any injury or death that results. In large-scale disasters, public authorities may declare crisis standards of care apply. This allows overwhelmed medical to triage patients, directing resources toward patients they think need it the most, by giving other patients less than the normal standard of care. For example, this occurred during the COVID-19 pandemic in Arizona. Children A special standard of care also applies to children, who, in a majority of jurisdictions, are held to the behavior that is reasonable for a child of similar age, experience, and intelligence under like circumstances. (Restatement (Second) of Torts §283A; Cleveland Rolling-Mill Co. v. Corrigan, 46 Ohio St. 283, 20 N.E. 466 (1889).) In some cases it means that more may be required of a child of superior intelligence. (Compare Jones v. Fireman's Insurance Co. of Newark, New Jersey, 240 So.2d 780 [La.App. 1970] with Robinson v.
