Monash University
Summary
This multicentre, adaptive, pragmatic, double-blind, three-arm, placebo-controlled, randomised, non-inferiority clinical trial will compare the incidence of surgical site infection and other healthcare associated infections, health economic and microbiological impact after intraoperative only (Arm A), to 24 hours (Arm B) and, to 48 hours (Arm C) of IV cefazolin and placebo postoperative surgical antimicrobial prophylaxis in patients undergoing cardiac surgery
Description
This trial will evaluate the clinical effectiveness, health-economic outcomes and microbiological impact of intraoperative (only) compared with intraoperative plus postoperative prophylaxis durations in patients undergoing cardiac surgery. CALIPSO, a multicentre, adaptive, double-blind, three-arm, placebo-controlled, phase IV, noninferiority trial will examine the incidence proportion of SSI following cardiac surgery. Our three-intervention trial will compare: Arm A Administration of prophylaxis in intraoperative period only Arm B Administration of prophylaxis in intraoperative plus for 24 h…
