[The physician's obligation to educate patients - legal aspects - patients' expectations].

There is some uncertainty among doctors and lawyers about the form and content of presurgical medical enlightenment of the patient. Presurgical enlightenment is of increasing significance with respect to malpractice suits. Current jurisdiction has developed principles of enlightenment that are often difficult for the doctor to handle. For routine procedures in major hospitals a standardized, pragmatically designed consent form is therefore necessary. At Würzburg University Eye Hospital the results of glaucoma and cataract surgery have been documented for years by using computer-readable forms. On the basis of these large-scale results from many thousands of procedures a written consent form was developed and tested for its suitability. Two hundred and twenty-two patients were questioned on their expectations as to proper enlightenment. The results of these broadly scattered interviews are summed up and presented. Especially with glaucoma patients, the best method of enlightenment, satisfying both medical and legal requirements, is an information booklet designed for lay people together with verbal information furnished by the doctor. Nearly all of the patients interviewed found the preoperative enlightenment complete and sufficiently clear. The majority ot them could repeat the contents of the enlightenment form four to six days after the operation. This speaks well for the adequacy of the enlightenment. As a rule, the written consent form was supplemented by verbal enlightenment from the operating physician immediately before hospitalization of the patient. A psychological investigation of preoperative anxiety with enlightened and non-enlightened patients revealed that the enlightenment form did not increase preoperative anxiety. Surgical ophthalmology lends itself to a written consent form more readily then other surgical disciplines, because diseases with poor prognoses for life are fortunately rare.
