Duration of Cardiac Antimicrobial Prophylaxis Outcomes Study

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

Detailed 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 hours postoperatively Arm C Administration of prophylaxis in intraoperative plus for 48 hours postoperatively
