UJI 13-1102. Duty of specialist.

__________________ (name of defendant), who held themselves out as a specialist in __________________ (area of specialty), having undertaken to [treat] [operate on] [make diagnosis of] [care for] a patient in this specialized field, is under the duty to possess and apply the knowledge and to use the skill and care ordinarily used by reasonably well-qualified specialists practicing under similar circumstances, giving due consideration to the locality involved. A doctor who fails to do so is negligent. [The degree of knowledge, skill, and care required of a specialist is usually higher than that required of a non-specialist, but it is never lower. Specialists are responsible for a certain base of knowledge in common with general practitioners, as well as additional knowledge in the field of their specialty.] [The only way in which you may decide whether the doctor in this case possessed and applied the knowledge and used the skill and care which the law required of them is from evidence presented in this trial by doctors testifying as expert witnesses. In deciding this question, you must not use any personal knowledge of any of the jurors.]
