A conceptual framework is outlined as the basis for analysis and evaluation of laboratory test-ordering patterns. This framework highlights the input, process, and output phases of the laboratory inquiry system. Data are presented from a contemporary Canadian study to show that the cost of laboratory testing is escalating and represents a sizable proportion of hospital costs. Practical policy interventions intent on reducing the costs in this complex system will require thorough analysis within a conceptual framework such as is outlined here and will require ultimately sophisticated control programs at various levels in the laboratory inquiry system.
本文概述了一个概念框架，作为分析和评估实验室检验医嘱模式的基础。该框架突出了实验室问询系统的输入、过程和输出阶段。文中呈现了一项当代加拿大研究的数据，以表明实验室检测成本正在不断攀升，且在医院成本中占相当大的比例。旨在降低这个复杂系统成本的实际政策干预措施，需要在这样一个此处概述的概念框架内进行全面分析，并且最终需要在实验室问询系统的各个层面制定完善的控制方案。
