It is customary for physicians and surgeons to recommend treatments that have the highest probability of getting the patient a good outcome. Deciding treatment based on results (outcomes actually achieved) has been advocated for hundreds of years. We are now in an era when practice recommendations are supposed to be based on evidence from randomized controlled trials.
