Clinical impact of the combination of rapid species identification and antifungal stewardship intervention in adults with candidemia

Background: Candidemia is associated with a high mortality rate. This study aimed to evaluate the clinical impact of a diagnostic intervention and antifungal stewardship in adults with candidemia, including effectiveness in facilitating appropriate antifungals and improving patient outcomes. Methods: A pre-post quasi-experimental study was conducted to analyze the impact of the integrated workflow of rapid species identification and antifungal stewardship intervention provided by infectious disease specialists for adults with candidemia at a medical center in southern Taiwan from March 1st, 2014 to February 29th, 2016. The primary endpoint was 30-day crude mortality, and secondary outcomes included the time to species identification, time to initial antifungal modification, and length of hospital stay. Results: Total 303 patients with candidemia were included, including 152 adults in the pre-intervention period (Mar. 1st, 2014–Feb. 28th, 2015; control group) and 151 in the intervention period (Mar. 1st, 2015–Feb. 29th, 2016; case group). Demographic and clinical characteristics of patients in two groups were similar. The case group had a shorter time to species identification (72 vs. 96 h, P
