Doctors have traditionally plied their trade.
The research is out there—thousands of studies are conducted on medical practices and products every year. Unfortunately, physicians don’t use much of it. Recent studies show that only about 15% of their decisions are evidence based. For the most part, here’s what doctors rely on instead: obsolete knowledge gained in school, long-standing but never proven traditions, patterns gleaned from experience, the methods they believe in and are most skilled in applying, and information from hordes of vendors with products and services to sell.
