In this study Dr. Sood and colleagues explore if the risk of a patient getting Clostridioides difficile Infection (CDI) is higher if the room was previously occupied by a C. diff patient. Previous single-center studies suggest that exposure to a room previously occupied by a patient with C. diff infection (CDI) may increase the risk of C. diff infection in subsequent patients. Dr. Sood and colleagues evaluated the risk of previous room occupant on CDI risk across 5 adult hospitals.
