Why do medical doctors usually not follow the scientific research backed guidelines for treating low back pain?

This USA Today article reviews a recent study from JAMA and the American College of Physicians guidelines.

As MDs like to promote themselves as scientific minded, why do you think so many MD's ignore the scientific based guidelines?
