The impact of EBM in medicine has been remarkable. The problem is to evaluate the benefits, but also the risks and its implications for clinical practice.
The number one thing I have viewed and believe to be the most important is that there is a huge decrease in the willingness of providers and insurance companies in "giving up" on certain patients. The old ideas of "we have tried everything possible" so we Quit, or just give up and put the patient to bed and allow him / her to die, is now long gone from the systems with good reputations. Most patients are no longer "fired" from their assigned practitioners and relapse is understood as a part of the disease process and the field has finally become a caring one. Research rocks!!
Have a look at the literature on "Measurement-based care", starting with
