Dr. Chuck Denham, once a leading voice for patient safety, will pay $1 million to settle civil allegations that he took kickbacks to promote a drug company's product in national health quality guidelines, the Justice Department announced Monday. Denham, a patient safety consultant from Laguna Beach, Calif., had allegedly solicited and accepted monthly payments from CareFusion Corp., maker of the antiseptic ChloraPrep, while serving as co-chairman of a National Quality Forum committee in 2009 and 2010.
