Johnson v. Kokemoor, 199 Wis. 2d 615, 545 N.W. 2d 495 (1996)
A doctor did not tell his patient that he was inexperienced in performing a difficult aneurysm surgery, that experienced surgeons could achieve better outcomes, and that he could refer the patient to a facility staffed with experienced surgeons. The doctor’s surgery left the patient a quadriplegic. Abrahamson’s opinion established that where provider-specific risk information is relevant to the patient’s decision, the doctor has a duty provide it before obtaining her “informed consent” to a procedure.
