Abstract

Background: Sternal wound infections continue to be a major source of morbidity and mortality after cardiac surgery. We undertook a multinational study to determine whether a detailed infection prevention protocol using a specific pre-, intra- and postoperative strategy including topical application of antibiotics would reduce the incidence of sternal infections.
Design: Quasi-Experimental Observation. Setting: Four heart centres in three different countries. Patients: 8,168 consecutive patients undergoing cardiac surgery from February 2006 to June 2015.
Method: In both groups, a second-generation cephalosporin was given prior to surgery and repeated if surgery exceeded six hours. Group A, but not Group B patients, received additional three doses of antibiotics after surgery while group B received intraoperative topical antibiotics and a special sternal closure protocol. Welch’s t-tests and χ2 analyses were used to test statistical significance. Additionally, logistic regression analyses were applied separated into Group A and B in order to examine the potential impact of established risk factors for sternal wound infections.
Results: There was a significant difference of major outcome parameters in favour of Group B vs. Group A: incidence of superficial wound infection: 0.4% vs. 2.9% (p<0.001); deep sternal wound infection: 0.6% vs. 2.2% (p<0.001); number of infection related reoperations: 81 vs. 241 (p<0.001) and number of muscle flap reconstruction in patients with sternal destruction: 0.2% vs. 1.1% (p<0.001).
Conclusion: The presented infection prevention protocol reduces postoperative sternal wound infections and limits the use of systemic postoperative antibiotics.
