Using expert process to combat Clostridium difficile infections.

In 2008, Clostridium difficile rates were increasing in Ontario, Canada, and in response, hospitals were mandated by the Ontario Ministry of Health to publicly report their C difficile infection (CDI) rates. In order to assist hospitals which had ongoing CDI outbreaks, a process of an external infection control resource team (ICRT) was introduced. This article describes the function and process of the ICRT, managed by Public Health Ontario, and reviews the lessons learned over the first 5 years of operation. These lessons may assist other hospitals in managing their own infection prevention and control outbreak.
