Many labs have not yet selected the most appropriate Westgard Quality Control (QC) rule for each test. This is mainly due to the apparent complexity of the matter.
From the Westgard OPSpecs Charts QC planning tool and the Sigma Metrics formula's it was deduced that every Westgard rule has its own Sigma value. This was converted to an easy three-step road map to optimal Westgard QC rules.
The road map provided is based on Sigma Metrics that hold a definition of "world class quality", at which no further effort to increase quality needs to be taken. Furthermore, it is shown that clinical chemical tests can be classified as "good": quality at or above world class, "bad": quality below world class but controllable with Westgard QC rules and "ugly": quality not controllable with Westgard QC rules alone. Finally, practical tips of how to deal with this and related aspects are given.
The use of the road map based on Sigma Metrics leads to fast and easy implementation of optimal Westgard QC rules.
许多实验室尚未为每个检测项目选择最合适的 Westgard 质量控制 (QC) 规则。这主要是因为这件事看起来很复杂。
从 Westgard OPSpecs Charts QC 规划工具和 Sigma Metrics 公式中推断出，每个 Westgard 规则都有自己的 Sigma 值。这被转化为一个简单的三步路线图，以找到最佳的 Westgard QC 规则。
所提供的路线图基于 Sigma Metrics，其定义为“世界级质量”，在这种质量水平下，无需再进一步努力提高质量。此外，结果表明临床化学检测可以分为“良好”：质量达到或高于世界级，“不良”：质量低于世界级，但可以通过 Westgard QC 规则控制，以及“丑陋”：质量不能仅通过 Westgard QC 规则控制。最后，给出了如何处理这方面和相关方面的实用技巧。
使用基于 Sigma Metrics 的路线图可快速、轻松地实施最佳 Westgard QC 规则。
