For the first time, clinical microbiologists have the option of purchasing or leasing a variety of automated blood culture systems. Although the performance characteristics of the BACTEC radiometric and nonradiometric blood culture systems are well-documented, we are only beginning to learn the performance characteristics of CMBCS. Well-designed and executed controlled clinical trials are needed to establish performance characteristics and to address issues that are unique to CMBCS. In particular, controlled clinical comparisons of different CMBCS are needed. In terms of the impact on clinical microbiology laboratories, there are no published data to support claims that the use of these systems decreases laboratory workload, staffing, or costs. Although such an impact seems reasonable and even likely, unequivocal documentation of such savings would make it easier for many laboratorians to justify the cost of purchasing or leasing one of these systems. Similarly, there are no published data regarding the long-term reliability of these systems while in clinical use. A documented track record of mechanical and electrical reliability would be useful to clinical microbiologists contemplating the acquisition of a new blood culture system.
临床微生物学家首次可以选择购买或租赁各种自动化血培养系统。尽管BACTEC放射性和非放射性血培养系统的性能特征已有充分记录,但我们才刚刚开始了解连续监测血培养系统(CMBCS)的性能特征。需要精心设计和执行的对照临床试验来确定其性能特征,并解决CMBCS特有的问题。特别是,需要对不同的CMBCS进行对照临床比较。就对临床微生物学实验室的影响而言,没有已发表的数据支持使用这些系统可减少实验室工作量、人员配备或成本的说法。尽管这种影响似乎合理甚至很可能,但明确记录此类节省将使许多实验室工作人员更容易证明购买或租赁其中一种系统的成本是合理的。同样,也没有关于这些系统在临床使用中的长期可靠性的已发表数据。一份记录在案的机械和电气可靠性记录对于考虑购置新血培养系统的临床微生物学家将是有用的。
