Aims and Objectives

Intra-abdominal infections (IAI) are common. National and international databases show that one in four cases of severe sepsis or septic shock is caused by IAI. It is the second most common focus of septic shock. Almost 90% of all intra-abdominal infections are so-called secondary peritoneal infections and primarily require a surgical approach. However, primary inadequate and inappropriate antibiotic regimens have a substantially worse prognostic outcome for patients with IAI and cause substantial increase in health care costs. In recent years the share of resistant species have increased worldwide. Especially in postoperative and tertiary peritonitis as well as with antibiotics pretreated necrotising pancreatitis, one has to assume an involvement of resistant or difficult to treat bacteria (MRSA, VRE, ESBL-producer, Pseudomonas spp. Acinetobacter spp. and Carbapenemase-producing organisms) and fungi. A multidisciplinary approach including surgeons, intensivists, clinical microbiologists and infectious disease specialists is necessary in order to save the lives of critically ill patients.

This Working Group aims to:

  • Develop commonly accepted, unified definitions of intra-abdominal infections
  • Harmonize different international and national guidelines for the antimicrobial treatment of complicated (c) IAI
  • Develop recommendations and decision-making processes for the diagnosis and treatment of cIAI due to resistant organisms
  • Support education and international collaboration in the field of cIAA

Our Work Plan is as follows:

  • Organise a constitutional meeting to establish the foundation of the Working Group (completed 2012)
  • Clearly define the aims of the Working Group (completed 2012)
  • Establish recommendations for the diagnosis and treatment of invasive intra-abdominal candidiasis (completed 2013)
  • Organise a symposium during ICC congress 2013 in Yokohama (completed 2013)
  • Develop practice guidelines for the antimicrobial treatment of cIAI (together with ESCIP of ESCMID, 2015 and 2016)
  • Promote an international network for interested colleagues (continuing process)
