Blood cultures frequently are obtained from patients with cancer who are suspected to have infection. A review of the literature revealed that consistent clinical guidelines or standards for obtaining blood cultures from patients with cancer do not exist. The published literature varies greatly with respect to site selection (peripheral or central), frequency, and timing. In addition, a survey at the researchers' institution revealed that blood culture orders were written and interpreted in various ways. After a multidisciplinary discussion, a review of the literature, and receiving expert advice, an institutional protocol for obtaining blood cultures from patients with cancer was developed. The protocol specifies between peripheral and central line sampling and establishes timing, frequency, and other guidelines so nurses can perform consistent and evidence-based blood culture sampling. Use of the protocol has improved patient care and helped standardize the practice of obtaining blood cultures.
血培养常用于疑似感染的癌症患者。文献综述显示，目前尚无针对癌症患者采集血培养的统一临床指南或标准。已发表的文献在采血部位选择（外周或中心）、频率和时机方面差异很大。此外，研究机构的一项调查显示，血培养医嘱的开具和解读方式各不相同。经过多学科讨论、文献综述并听取专家意见后，制定了一项针对癌症患者采集血培养的机构方案。该方案明确了外周血和中心静脉血采样的相关内容，并确定了采血时机、频率和其他指南，以便护士能够进行规范且基于证据的血培养采样。该方案的使用改善了患者护理，并有助于规范血培养采集操作。
