Shared perioperative decision making: a shift in the doctor-patient paradigm.

The high-risk surgical patient only constitutes approximately 4% of the elective non-cardiac surgical population but contributes to the vast majority of in-hospital deaths following surgery. This, in conjunction with a high morbidity rate, can lead to a perioperative pathway fraught with challenges. It is incredibly difficult to anticipate which complications may arise and the risks involved before surgery. It is for this reason that patients need to be engaged in the decision-making processes regarding their perioperative care involved before major surgery. A combination of good medical practice, medicolegal influences and a governmental drive have begun to result in a shift away from paternalistic medicine to a shared decision-making approach. This article defines shared decision making, explores its benefits and limitations and addresses the relevant legal literature.
