Extended systemic antibiotic prophylaxis in ventricular assist device recipients, an infectious disease perspective.

Abstract

OBJECTIVES:

To evaluate whether mediastinitis/deep sternal wound infection (Med/DSWI) is more common in ventricular assist device (VAD) with delayed sternal closure (DSC) compared to VAD with primary sternal closure (PSC).

METHODS:

A literature search was done over the last four decades for studies that addressed this comparison.

RESULTS:

Two studies met our inclusion criteria, and their results are contradictory. The first study compared 184 VAD recipients with PSC to 180 VAD recipients with DSC. There was no difference in VAD-related infections between DSC and PSC (15% vs. 16%, respectively; odds ratio = 0.965, 95% confidence interval [CI] = 0.525-1.635). The second study compared 464 VAD recipients with PSC to 94 VAD recipients with DSC. The rate of surgical site infection was higher in the DSC patients (12.5% vs. 1.4%, respectively; odds ratio = 10.1; 95% CI = 3.8-27.0). DSC was identified as an independent risk factor for postoperative mortality, but no detailed infection information was given.

CONCLUSIONS:

There is no clear evidence of the association between DSC, compared to PSC, and Med/DSWI. Therefore, DSC is not an absolute indication for extended systemic antibiotic prophylaxis. The decision to extend the duration of systemic antibiotic prophylaxis should be made on a case-by-case basis, in collaboration with an infectious disease specialist.
