Sterile blood culture (BC) collection procedures are important to prevent the consequences of contamination, namely, prolonged patient hospitalisation, unnecessary antimicrobial exposure and an increase in hospital costs. Blood culture contamination rates were determined at different hospitals in the Cape Metropole over a 3-year period. Study findings showed that contaminated BCs have a financial impact on the healthcare system and contamination rates remain above accepted international standards, except in the presence of a phlebotomist team. High BC contamination rates might be reduced by the implementation of cost-effective educational intervention programmes, which reminds healthcare workers to collect BC samples aseptically.
无菌血培养（BC）采集程序对于预防污染后果非常重要，这些后果包括患者住院时间延长、不必要的抗菌药物暴露以及医院成本增加。在三年时间里，对开普敦都会区不同医院的血培养污染率进行了测定。研究结果表明，污染的血培养对医疗系统有经济影响，除了有采血团队的情况外，污染率仍高于国际公认标准。实施具有成本效益的教育干预计划可能会降低较高的血培养污染率，该计划可提醒医护人员无菌采集血培养样本。
