建立基于能力指数的实验室质量控制数据室间比对系统。
室内质控系统配置比对项目和规则，录入质控数据后系统自动计算能力指数，每隔10天各实验室同一项目最小能力指数传输至室间比对系统，分别与绝对标准、相对标准及历史结果的比较，得到各实验室比对结果，帮助实验室进行质量控制改善。
建立室内质控数据室间比对系统，根据WS/T403-2012标准，97%比对批次显示精密度处于良好及以上，总胆固醇和血糖共计5个批次提示精密度一般，需个别改善；95.8%比对批次显示准确度良好及以上，系统误差是导致酶类项目性能降低的主要因素。
基于能力指数的临床实验室室内质量控制数据室间比对系统，可从精密度和正确度两个方面帮助管理者发现质控隐患，并依据当前技术水平提供各项目的性能改进建议，确保患者结果安全。
To establish laboratory quality control comparison system based on capability index.
The quality control system is configured with comparison groups and selected rules. The capacity index is calculated after the quality control data is entered. The minimum capacity index of the same project of each laboratory is transmitted to the comparison system every ten days, and then compared with the absolute standard, the relative standard and the historical results respectively. The comparison results of each laboratory are gained to help the laboratory improve the quality control.
The quality control comparison system is established. According to the WS/T403-2012 standard, 97% of the compared batches show a good or or above precision. However, five batches of total cholesterol and glucose show a general precision, which needs to be improved individually. Moreover, 95.8% of the compared batches show good or above accuracy and the system error is the main factor leading to the degradation of enzyme project performance.
The comparison system based on capability index can helps managers to identify potential quality control hidden dangers in terms of precision and accuracy, and provide performance improvement suggestions for various testing items according to the current technical level, and ensure the safety of patients’ results.
