In a single generation, the evidentiary basis for the practice of medicine has grown from a dream to a massif. No longer need physicians rely solely on experience and opinion in formulating diagnostic and therapeutic approaches to the care of the patient.
However, for any given clinical challenge, the available science is never flawless, monolithic or comprehensive, nor is it likely to be durable in the face of newer studies.
The international medical community has mounted two approaches to sorting the wheat from the chaff: One targets the doctor in convening committees to formulate guidelines for patient care. The other targets the patient for evaluating options, so-called informed medical decision making. Both approaches are now sizable undertakings clothed in organizational imprimaturs and girded by self-promotion.
But they are largely parallel undertakings with work products that can cause considerable cognitive dissonance on the part of the patient and the physician. In a recent article in the British Medical Journal [1] the Guideline Development Group convened by the National Institute for Health and Clinical Excellence (NICE) summarized the thinking behind the guidance it was offering regarding the management of STEMI. This is an object lesson in such cognitive dissonance.
