Within the scope of this paper, the Working Group has attempted to place external quality assessment (EQA) within the whole context of quality management in laboratory medicine. First, the objectives of EQA schemes are defined and current EQA schemes evaluated. In most schemes, the objectives are not defined a priori and do not allow the definition of the origin of unacceptable individual results from participants. There is an ongoing trend for making traditional EQA schemes more interesting for the participants. Analysis of the factors involved in analytical quality allow the definition of the essential analytical tasks of educational EQA schemes. Beside these quality control tasks, educational EQA also includes quality assurance elements. EQA today has not only an important role to play in the assessment of each participant's performance but also in the assessment of the method. Efficiency of the schemes and educational impact can be improved by appropriate scheme designs according to objectives. After this theoretical approach, some practical examples of problem related EQA designs are given.
在本文范围内，工作组试图将外部质量评估（EQA）置于检验医学质量管理的整体背景中。首先，明确了EQA计划的目标并对当前的EQA计划进行了评估。在大多数计划中，目标并非预先确定，也无法确定参与者不可接受的个别结果的来源。目前有一种趋势，即让传统的EQA计划对参与者更具吸引力。对分析质量相关因素的分析有助于确定教育性EQA计划的基本分析任务。除了这些质量控制任务外，教育性EQA还包括质量保证要素。如今，EQA不仅在评估每个参与者的表现方面发挥着重要作用，而且在方法评估方面也发挥着重要作用。根据目标进行适当的计划设计可以提高计划的效率和教育影响。在进行了这种理论探讨之后，给出了一些与问题相关的EQA设计的实际例子。
