It is unknown whether infectious diseases consultation improves outcomes for enterococcal bacteraemia in a multicentre healthcare system.This retrospective multicentre observational cohort study included 250 adult patients with enterococcal bacteraemia between July 2016 and December 2020. The primary endpoint was a composite of clinical failure, including persistent bacteraemia, persistent fever, and in-hospital mortality. Secondary endpoints included adherence to a treatment bundle (appropriate empiric and definitive antibiotics, appropriate planned treatment duration, obtaining repeat blood cultures and an echocardiogram).Clinical failure occurred in 35 of 155 patients (22.6%) with an infectious diseases consultation and 16 of 95 patients (16.8%) without an infectious diseases consultation (P = 0.274). Multivariate analysis identified vasopressors as the only independent predictor of the primary outcome. Infectious diseases consultation resulted in higher adherence to a treatment bundle, including echocardiogram (75.5% vs. 34.7%; P0.0001), repeat blood cultures (85.2% vs. 68.4%; P = 0.002), appropriate definitive antibiotics (70.5% vs. 91.6%; P0.0001) and appropriate planned durations of therapy (81.1% vs. 94.2%; P = 0.001). More patients in the consult group were treated with ampicillin (47.1% vs. 22.1%; P0.0001) and fewer were treated with vancomycin (17.4% vs. 24.2%; P = 0.068).Despite finding no difference in clinical failure between groups, this study highlights important benefits of infectious diseases consultation in enterococcal bacteraemia. |
