I understand the need for clinical guidelines to be written conservatively to ensure that their recommendations are firmly based in sound science, but it's an unfortunate reality that the elapsed time from research to clinical practice is typically 20 years or more, no matter the medical discipline one is discussing. I'm a published author in the medical field and I've encountered quite a few physicians lamenting the typical 20-30 year lag from research to practice.
Plus, when you factor in the economic factors that minimize research into less profitable treatments (read: not patentable means ignored or misrepresented by the "experts"), the tendency for "peer review" to actually mean the loudest, not the most accurate, medical opinion rises to the top, and the blatant subterfuge perpetrated by the pharmaceutical industry, it's highly unlikely that clinical practice guidelines will be that path to success for very many of us.
