How to Join

ISAC Working Groups are open to new members with a strong interest and relevant experience in the given field. To join an ISAC Working Group, please contact Fee Johnstone, ISAC Executive Officer with your name and a brief C.V. We welcome new members!

Aims and Objectives

Infections in the intensive care unit (ICU) represent the nosocomial infections of the near future as it is predicted that hospitals of the future will be transformed into massive ICUs and other units providing increased levels of care. Generally, patients who are transferred from the ICU to hospital wards are colonised with antimicrobial-resistant bacteria, providing a focus for spread and colonization of the whole hospital. Thus, today’s ICUs are of major concern regarding both prevention and therapy of the nosocomial infections arising in their environment. Ventilation associated pneumonia (VAP) and central catheter-associated infections represent the majority of ICU infections, with mortality rates exceeding 30%. The principle causes are multi-resistant strains of Pseudomonas aeruginosa, Acinetobacter baumannii, Klebsiella species producing ESBLs, MRSA and VRE strains.

This Working Group aims to:

  • Enhance the epidemiological surveillance of nosocomial ICU infections
  • Promote antibiotic resistant surveillance in ICUs
  • Evaluate therapeutic decisions in the ICU. These include antibiotic rotation, restriction and de-escalation policies, in order to prevent and/or reduce resistance rates by applying well-organised protocols
  • Evaluate the validity of surveillance cultures as a guide to empirical antimicrobial therapy
  • Promote the implementation of “hand-hygiene protocols”.


Hot topics on infections in critical care

The Infections in the ICU and Sepsis Working Group held a webinar in December 2021.:

Infections represent a major cause of morbidity and mortality in the critical care setting, especially in our era of multidrug-resistant pathogens.

During the COVID19 pandemic, on the other hand, a significant increase in the prevalence of ICU infections has been reported. Prompt diagnosis of critical care infections and appropriate treatment in optimised doses, along with antibiotic stewardship, are of outmost importance for improved outcomes and tackling antimicrobial resistance development.

In this online event, internationally leading experts provided short presentations with up-to-date information on trending topics of infection and sepsis in critical care.
