OBJECTIVE
To describe how frequently blood cultures (BCs) are obtained in the ED and to describe the incidence of true- and false-positive BC results.
METHODS
Retrospective descriptive study of all patients presenting to a tertiary-level, mixed Australian ED over a 15 month period.
RESULTS
A total of 3617 (3.67%) patients had BCs collected. Around one (12.1%) in eight of these BCs were positive; nearly half (45.2%) of which were identified as a false positive.
CONCLUSIONS
BCs are a common investigation in the ED with a high false-positive rate. Strategies are required to reduce false positives, including reducing inappropriate collection and improving collection techniques.
目的
描述在急诊科进行血培养（BC）的频率，并描述血培养结果真阳性和假阳性的发生率。
方法
对在15个月期间就诊于澳大利亚一家三级综合性急诊科的所有患者进行回顾性描述性研究。
结果
共有3617例（3.67%）患者进行了血培养。其中约八分之一（12.1%）的血培养结果为阳性；其中近一半（45.2%）被判定为假阳性。
结论
血培养在急诊科是一项常见检查，但假阳性率很高。需要采取策略来减少假阳性，包括减少不适当的采血以及改进采血技术。
