Informed consent, a reappraisal of patients' reactions.

In response to the November 1972 ruling of the California Supreme Court requiring complete, detailed disclosure of risks for procedures and treatments, a survey was made of the reactions of one hundred patients to this decision. A fictional man was described with a clinical diagnosis of brain tumor, and then the procedure for cerebral angiography and all of that procedure's potential complications were described. The majority of the patients surveyed responded that this complete disclosure of risks helped them in making an intelligent decision about giving consent for the procedure. However, 50 percent of these patients would have withheld consent for the procedure on learning of the complications. Although physicians would have reacted differently, it is certainly the patients' right to make the choices they did.
