Time to positive culture and identification for Candida blood stream infections

Fernandez, Julianna, Erstad, Brian L., Petty, Wanda, Nix, David E.·2009·Diagnostic Microbiology and Infectious Disease

Abstract

Candidemia and delay to appropriate therapy contribute to increased morbidity and mortality. Current literature addresses the delay between blood culture collection and final identification; however, it fails to delineate differences among species. The purpose of this study was to quantify the time to yeast detection and identification relative to blood culture collection and determine whether differences exist among species. In this retrospective study, all cases of Candida isolation for 2 years were reviewed. The time delays between blood culture and detection of Candida growth were quantified as well as the additional time required for final species identification. Initiation of antifungal therapy was assessed in relation to culture collection, detection of yeast, and final identification. The appropriateness of therapy at each time point was also analyzed. Most Candida infections were caused by either Candida albicans (n = 43) or Candida glabrata (n = 27). Mean time to positive yeast detection for C. albicans was 35.3 +/- 18.1 h, whereas that of C. glabrata was 80.0 +/- 22.4 h (P < 0.0001). Mean time to final identification for C. albicans was 85.8 +/- 30.9, whereas that of C. glabrata was 154 +/- 43.8 h (P < 0.0001). Mean time to appropriate therapy for C. albicans isolates was 43.3 +/- 27.6 h compared with 98.1 +/- 38.3 h (P < 0.0001) for C. glabrata isolates. The time delay between blood culture collection and yeast detection as well as final identification was significantly longer for C. glabrata isolates when compared with C. albicans. As a result, mean time to appropriate antifungal therapy was significantly longer in patients with C. glabrata isolates.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
