As superbug outbreaks raised alarm across the country last year, a prominent doctor at a Philadelphia cancer center wrote in a leading medical journal about how to reduce the risk of these often-deadly patient infections. Dr. Jeffrey Tokar, director of gastrointestinal endoscopy at Fox Chase Cancer Center, pointed to recent outbreaks from contaminated medical scopes and discussed steps doctors and hospitals should take to ensure patient safety in his Sept. 22 article in the Annals of Internal Medicine. "Health care facilities and providers should strive to establish an environment of open information exchange with patients about what is being done to maximize their safety," Tokar and his two co-authors wrote.
