Sampling practices determine the accuracy of blood culture in diagnosing bloodstream infection. The main acute hospital in this study introduced aerobic-only routine blood cultures aiming to increase the volume and number of aerobic samples. At the smaller acute site, aerobic-anaerobic pairs were sent routinely. Culture yield and sampling practices were compared at these two sites and it was found that anaerobic cultures increased the yield of pathogens including facultative anaerobes. Volume cultured and number of samples sent fell short of national recommendations. The aerobic-only policy did not result in more blood being cultured. Based on these findings, the main acute hospital is reintroducing aerobic-anaerobic pairs for routine culture.

对仅需氧培养的血液进行十二年分析，以常规检测菌血症。

采样方法决定了血液培养在诊断血流感染中的准确性。在这项研究中，主要的急性医院引入了仅需氧的常规血液培养，旨在增加需氧样品的数量和数量。在较小的急性部位，常规发送有氧-无氧对。在这两个地点对培养物的产量和取样方法进行了比较，发现厌氧培养物增加了包括兼性厌氧菌在内的病原体的产量。培养的体积和送出的样品数量均未达到国家建议。仅需氧运动的政策并未导致培养更多的血液。基于这些发现，主要的急性医院正在重新引入有氧-无氧对以进行常规培养。
