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:
