Is a plaintiff entitled to special instruction No. 24 in a medical malpractice case?

The trial court refused plaintiffs' special instruction No. 24, which read: "When surgery or other dangerous therapeutic procedures are being considered, the physician must inform the patient of the available alternatives or schools of thought and the hazards involved so that the patient is able to give effective consent to the proposed treatment." Plaintiffs, relying on the decision in Jamison v. Lindsay (1980) 108 Cal.App.3d 223, 166 Cal.Rptr. 443, contend that the court's refusal to give this instruction constitutes reversible error.
