This is a trick question. The catch? that medicine is an art will always apply when judgement is necessary, not to mention the impact of a particular skill of a diagnostician or the technical prowess of someone doing procedures. But it is true that 'evidence-based medicine' is probably here to stay. Since Medicare is heavily invested in it as part of a 'best practices' modality, the same prior authorization constraints will be applied by the other third-party payers. Nowhere is this more obvious than in ophthalmology, where overhead keeps going up and reimbursements, down. Unfortunately, evidence-based medicine is Gaussian and doesn't take into account the 'outliers' of the bell curve, for which thinking outside of the curve is indicated--the 'zebras' in medicine. You need to include something about that in your answer.
