评估患者数据移动均值法在新生儿遗传代谢病筛查日常室内质量控制中的应用价值。
收集2019年03月至2019年12月镇江市新生儿疾病筛查中心的16 731例新生儿足底血干血片样本,检测促甲状腺激素(Thyroid Stimulating Hormon, TSH)和苯丙氨酸(Phenylalanine, Phe)的浓度,计算每批实验的患者数据均值、SD值和CV值,计算同批次商品质控的、SD值和CV值,绘制Levey-Jennings质控图,以+2SD为警戒限,±3SD为失控限,比较各项质控指标,分析其提示异常的原因。
TSH的42批数据中有8批超过±2SD控制限,提示"警告",其中商品质控异常6批,患者数据均值异常2批,仅有1批同时异常;Phe的42批数据中有3批超过±2SD,提示"警告",其中商品质控异常1批,患者数据均值异常2批。分别根据异常提示分析原因进行纠偏。
建立本实验室的患者数据移动均值室内质控方法,用于TSH和Phe测定的质量控制,有效弥补商品质控的使用局限性,是对常规室内质控方法的优化补充。
To evaluate the application value of patient data in internal quality control (IQC) of newborn screening (NBS).
From March 2019 to December 2019, blood samples of 16 731 newborns from Zhenjiang newborn disease screening center were collected to detect the concentration of thyroid stimulating hormon (TSH) and phenylalanine (Phe). To calculate the patients' index, including data , SD value and CV value, SD value and CV value, each batch of the patient data and the value of commodity quality control product synchronously, and to draw the levey-jennings quality control chart, take ±2SD as the warning limit and ±3SD as the control limit, compare the quality control indicators, and analyze the reasons for their abnormal indications.
Among the 42 batches of TSH data, 8 batches exceeded the control limit of ±2SD, indicating "warning". Among them, 6 batches were abnormal in routine quality control, 2 batches were abnormal in the mean value of patient data, and only 1 batch was abnormal at the same time. Analysis of the reasons for the correction according to the abnormal prompt.
Quality control method was established in accordance with the patient data, so as to analysis and adopt the quality control on TSH and Phe. The quality control of patient data by moving average method is an optimization supplement to the conventional internal quality control.
