One size rarely fits all. Most medical knowledge is derived from studying groups of subjects, subjects who may be different in some way from the individual who walks into the doctor’s office. Basing medicine only on randomized controlled studies can lead to over-simplified “cookbook” medicine. A good clinician interprets study results and puts them into context, considering the whole patient and using clinical judgment to apply current scientific knowledge appropriately to the individual.
CAM practitioners claim to be providing individualized treatments. Homeopaths look up symptoms like “dreams of robbers,” “sensation of coldness in the heart,” and “chills between 9 and 11 AM” in their books, and naturopaths quiz patients in great depth about their habits and preferences; but they don’t have a plausible rationale for interpreting the information they gather. And they have not been able to demonstrate better patient outcomes from using that information.
A new concept, “precision medicine,” was recently featured in UW Medicine, the alumni magazine of my alma mater, the University of Washington School of Medicine. Precision medicine strives to provide truly individualized care based on good science. It identifies the individual variations in people that make a difference in our ability to diagnose and treat accurately. Peter Byers, MD, director of the new Center for Precision Diagnostics at the University of Washington, calls it “the coolest part of medicine.” (more…)
