STUDY OBJECTIVE
To assess the clinical value of blood cultures (BCs) in the management of adult patients discharged from the emergency department (ED) with a diagnosis of community acquired pneumonia (CAP).
METHODS
The courses of antibiotic regimens and outcomes of patients with positive BC results were examined to assess their influence on BCs.
RESULTS
BCs were obtained from 289 outpatients. Six clinically significant organisms were identified (a yield of 2.1%). Outpatients with CAP who had blood cultures performed had a 0.69% (2 of 289) chance of having a change of treatment directed by the results of the culture.
CONCLUSION
BCs have little utility in the ambulatory management of CAP.
研究目的
评估血培养（BC）在诊断为社区获得性肺炎（CAP）并从急诊科（ED）出院的成年患者管理中的临床价值。
方法
检查血培养结果为阳性的患者的抗生素治疗疗程和结局，以评估其对血培养的影响。
结果
从289名门诊患者中获取了血培养样本。鉴定出6种具有临床意义的病原体（检出率为2.1%）。进行了血培养的CAP门诊患者因培养结果而改变治疗的几率为0.69%（289例中有2例）。
结论
血培养在CAP门诊管理中的作用不大。
