Complementing the inflammatory work in chronic disease patients is the work carried out in heart surgery patients receiving cardiopulmonary bypass (CPB). These patients are prone to systemic intravascular haemolysis and an acute systemic inflammatory response to bypass. Prof. Landis has a longstanding interest in defining the molecular mechanisms of the systemic inflammatory response and has led international efforts to evaluate the evidence base of antiinflammatory interventions. One of the problems in assessing the evidence base is the lack of consensus on which inflammatory markers and clinical outcomes should be reported. The 2010 Outcomes Consensus Statement was authored by leading inflammation experts in the field, including Stephen Westaby who described the condition in 1993, attending the Outcomes heart


The consensus panel was tasked with the second step of a process begun at the previous year’s Outcomes conference, also held in Barbados. The panel considered the list of proposed inflammatory markers and clinical outcomes from the previous consensus panel and consolidated these into three recommendations ‐ linked to three tables ‐ for investigators to report on the systemic inflammatory response.

Main Results:

The recommendations state the following: 1) measure at least one inflammatory marker, using a broad definition of the term, 2) measure at least one clinical end‐point, drawing from a list of practical yet clinically meaningful endpoints suggested by the consensus panel, and 3) report a core set of CPB and perfusion criteria that may be linked to outcomes.

Expected Impact:

It is our collective belief that adhering to these simple consensus recommendations will help define the influence of CPB practice on the systemic inflammatory response, advance our understanding of causal inflammatory mechanisms, and standardize the reporting of research findings in the peer‐reviewed literature. The Outcomes Consensus Statement may also be used to define inclusion criteria for systematic reviews of the literature.

Next Steps / Future Plans:

To use the 2010 Outcomes criteria as inclusion criteria by the STS/SCA Perfusion Guidelines Writing Group in order to evaluate the evidence base for anti‐inflammatory interventions in cardiopulmonary bypass.
