Evidence-based guidelines for managing patients with intra-abdominal infection were prepared by an Expert Panel of the Surgical Infection Society and the Infectious Diseases Society of America. These updatedguidelines replace those previously published in 2002 and 2003. The guidelines are intended for treating patients who either have these infections or may be at risk for them. New information, based on publications from the period 2003–2008, is incorporated into this guideline document. The panel has also added recommendations for managing intra-abdominal infection in children, particularly where suchmanagement differs from that of adults; for appendicitis in patients of all ages; and for necrotizing enterocolitis in neonates. EXECUTIVE SUMMARY The 2009 update of the guidelines contains evidencebased recommendations for the initial diagnosis and subsequent management of adult and pediatric patients with complicated and uncomplicated intra-abdominal infection. The multifaceted nature of theseinfections has led to collaboration and endorsement of these recommendations by the following organizations: American Society for Microbiology, American Society of Health-System Pharmacists, Pediatric Infectious Diseases Society, and Society of Infectious Diseases Pharmacists. These guidelines make therapeutic recommendations on the basis of the severity of infection, which is defined for theseguidelines as a composite of patient age, physiologic derangements, and background medical conditions. These values are captured by severity scoring systems, but for the individual patient, clinical judgment is at least as accurate as a numerical score [1–4]. “High risk” is intended to describe patients with a range
