“Evidence-based medical treatment guidelines” sounds like such a good idea. Who would want medical treatment that wasn’t based on evidence?
The problem is in the details. Way back in 1996, when “evidence-based medicine” was coming to the fore, the originators of the concept went out of their way to say “evidence-based medicine is not cookbook medicine,” and that it can “never replace individual clinical expertise and it is this expertise that decides whether the external evidence applies to the individual patient at all, and if so, how it should be integrated in a clinical decision.”
Fast-forward twenty years, and now the Pennsylvania General Assembly is considering whether to use evidence-based medicine as the sort of “cookbook medicine” it was never meant to be.
