Reveles Traces Rate of Hospital Infections

Dr. Kelly Reveles, assistant professor of pharmacotherapy, is primary author of a study which found that the incidence of Clostridium difficile infection (CDI), a highly contagious gastrointestinal disease often linked to the overprescribing of antibiotics, nearly doubled between 2001 and 2010. It also determined there were no improvements in patient health outcomes, including mortality or hospital length of stay, over the study period.
