Impact of Infectious Diseases Consultation in Patients With Candidemia at a Multisite Health Care System With Established Antimicrobial Stewardship and Telemedicine Services.

Abstract

Infectious diseases consultation improves outcomes in patients with candidemia, although some facilities lack access to consultation. This multisite health care system study compared in-hospital mortality in patients with candidemia across 3 groups-those who received on-site consultation, telemedicine consultation, or no consultation. All patients were reviewed by an antimicrobial stewardship pharmacist. A retrospective observational cohort study was performed of adult hospitalized patients with candidemia from January 2018 to October 2021. The primary outcome was in-hospital mortality. Secondary outcomes included receipt and duration of antifungals, removal of central venous lines if present, ophthalmologic examination, echocardiography, and determination of infection source. A total of 265 patients were evaluated: 187 in the on-site consultation group, 49 in the telemedicine consultation group, and 29 in the nonconsultation group. Although in-hospital mortality did not differ significantly between the on-site and nonconsultation groups, it was significantly lower in the telemedicine group when compared with the nonconsultation group (10.2% vs 34.5%, P = .009). Patients who received on-site or telemedicine consultation had significantly more antifungal therapy initiated, appropriate therapy duration, central lines removed, and echocardiography performed, as well as fewer unknown candidemia sources, vs those in the nonconsultation group. This is the first study of a multisite health care system providing telemedicine services to evaluate the impact of infectious diseases consultation on candidemia mortality. These findings suggest that when on-site consultation is unavailable, infectious diseases telemedicine consultation and antimicrobial stewardship can improve outcomes and should be considered for all patients with candidemia at resource-limited sites.
