SIRS was a multicentre, international, randomized, controlled, double-blind placebo-controlled trial of high-risk adult patients undergoing cardiopulmonary bypass.
Patients were randomly allocated to receive 500 mg of methylprednisolone divided into two intravenous doses of 250 mg each, one during anesthetic induction and the other on CPB initiation, or matching placebo.
1) Total mortality within 30 days post-surgery and;
2) Composite of total mortality, MI, stroke, renal failure, or respiratory failure within 30 days post-surgery.

He values his ongoing collaborations with PJ Devereaux and other leading clinician-scientists at PHRI, which has led to several sub-studies funded by the Canadian Institutes of Health Research which examined the effects of perioperative interventions on the risk of acute kidney injury (off-pump cardiopulmonary bypass surgery) in the CORONARY study, and more. A current interest is in pragmatic randomized trials embedded into routine healthcare delivery.
