Intensive Care Service Research

The RPA Intensive Care Service (ICS) conducts and participates in research activities at a local, national, and international level. Our participation in clinical research exerts a positive influence on the quality of care for all the critically ill adults that we care for. The ICS has an active local research program and makes a prolific contribution to investigator-initiated randomised clinical trials in intensive care medicine via its membership of the Australian and New Zealand Intensive Care Society Clinical Trials Group (ANZICS CTG). 

RPA is one of the few hospitals in Australia which provides an Extracorporeal Membrane Oxygenation (ECMO) service. The Intensive Care Service, in collaboration with the Cardiology, Anaesthetics and Cardiothoracic Surgery Departments, has established an ECMO research program to further refine this advanced form of life support.
