Y1 - 2022 N1 - T2 - Maxcy-Rosenau-Last Public Health & Preventive Medicine, 16e AB - Clostridioides difficile (formerly known as Clostridium difficile) infection (CDI) has emerged as a pathogen of major importance among hospitalized and ambulatory patients. It now rivals methicillin-resistant Staphylococcus aureus (MRSA) as the leading cause of nosocomial infections,1 and is increasingly encountered among ambulatory patients,2 often with little to no prior contact with the healthcare system. Because of increased incidence and severity, and the high likelihood of recurrent disease after initial successful treatment, CDI has imposed a large burden on healthcare systems across the world. This burden is manifested by a high rate of morbidity and mortality, financial costs, and a high consumption of healthcare time and effort devoted to testing, infection control, cleaning, and reporting.3 Because of this substantial impact on the healthcare system, the United States Centers for Diseases Control and Prevention (CDC) designated C. difficile as one of five “urgent” threats in its 2019 Antimicrobial Resistance Threat Report,4 joining drug-resistant Neisseria gonorrhoeae, carbapenem-resistant Enterobacteriaceae, carbapenem-resistant Acinetobacter, and Candida auris in this top tier. Challenges and controversies regarding epidemiology, testing, treatment, prevention, and transmission of C. difficile have emerged (and sometimes re-emerged) over the past two decades, creating difficulties for clinicians and persisting questions for researchers studying CDI.
