Medical paternalism is a set of attitudes and practices in medicine in which a physician determines that a patient's wishes or choices should not be honored. These practices were current through the early to mid 20th century, and were characterised by a paternalistic attitude, surrogate decision-making and a lack of respect for patient autonomy. It is almost exclusively undertaken with the intention of benefiting the patient, although this is not always the case. In the past, paternalism was considered an absolute medical necessity, as there was little to no public understanding of medical procedures and practices. However, in recent years, paternalism has become limited and blind faith in doctors' decisions has come to be frowned upon.
