摘要
为高通量连续工作分析仪建立限定区间统计质量控制计划时,分析批长度(或质量控制频率)的优化是一项重要内容。合理的分析批长度有助于及时检出误差,降低系统误差所致的不可接受患者结果数,从而最小化患者风险。但目前缺乏简单实用的工具帮助实验室优化分析批长度,导致实验室的质控实践与理论间存在明显的差异。对此,Westgard以不可接受患者结果最大预期数目[MaxE(Nuf)]为基础,将Sigma度量分析批长度列线图与Westgard西格玛规则流程图相结合,建立了分析批长度Westgard西格玛规则流程图。该工具图简单直观,实验室根据检测方法的Sigma度量值即可选择适当的质控规则、每次质控测定数量以及分析批长度,以此为连续工作分析仪建立科学客观的限定区间质控策略,达到患者风险最小化的目标。
For the bracketed statistical quality control(SQC)of high-volume continuous production analyzers,it is important to optimize the run size or the freque-ncy of QC.The run size appropriate for the different SQC procedures can detect error condition timely,which will reduce the number of unacceptable patient results during the existene of an undetected error condition and minimize the patient risk〉However,the lack of simple and practical tools to optimize run size makes it difficult for laboratory practice〉Based on the maximum expected number of unacceptable final patient results[MaxE(Nuf)],Westgard created a diagram called Westgard Sigma Rules with Run Size,which combines Sigma-Metric Run Size Nomogram and Westgard Sigma Rules.Once the sigma quality of the tests and methods in laboratories were calculated.The simple practical tools can help laboratory to select the right control rules,the right number of control measurements and the right run size for bracketed SQC of continuous production analyzers so as to realize the patient risk minimization.
