I've heard that it takes 12 to 18 years for information from studies to filter down to the doctor. Is this really true? How do I know if my doctor is keeping up?

That statistic has been quoted many times by many people. There is a general truth behind the statement. It does take some time for information to filter down from the scientist to the clinician.

When a study first comes out, it has to be repeated by other researchers with the same results to confirm the findings. Usually, more than one study must repeat the process and validate the findings. When there's enough evidence, then guidelines may be presented to help identify what is the best approach to each problem.

This process has been speeded up now in today's electronic age. Information is passed back and forth and accessed much faster than ever before. The media is also very good about letting the public know the latest findings. This gives patients a chance to research information for themselves and ask their doctors more specific questions about their condition.

Physicians who are board certified show that they are keeping up by taking this test in their specialty area. They must be re-certified periodically, which means reviewing studies and information and staying current in their field.
