2018-2023年重庆市肌钙蛋白POCT室间质量评价结果分析

Analysis of external quality assessment for cardiac troponin POCT in Chongqing from 2018 to 2023

目的分析2018-2023年重庆市肌钙蛋白即时检测(POCT)室间质量评价(EQA)结果,了解重庆市肌钙蛋白POCT检测现状,为提高重庆市肌钙蛋白POCT检测能力提供依据。方法收集2018-2023年参加重庆市临床检验中心肌钙蛋白POCT EQA实验室结果,并进行统计分析。结果2018-2023年参加重庆市肌钙蛋白POCT EQA的实验室数从36家增加至88家,所使用的仪器品牌分组数从无增加至8个,每批次实验室合格率从最低26.32%增加至最高89.77%,但仍存在各仪器品牌分组靶值差异较大的现象,2023年各批号分组靶值的变异系数为44.72%~105.69%。结论重庆市肌钙蛋白POCT EQA参加率和检测水平尚有待提高,需持续将肌钙蛋白POCT纳入EQA计划,以定期监测全市范围内该项目的检测质量,为临床诊疗提供快速、可靠的保障。

Objective To improve the detection ability and to know the current situation of Chongqing point of care testing(POCT)of cardiac troponin by analyzing the external quality assessment(EQA)of cardiac troponin POCT from 2018 to 2023 in Chongqing.Methods The results of troponin POCT EQA laboratory in Chongqing Center for Clinical Laboratory from 2018 to 2023 were collected and statistically analyzed.Results From 2018 to 2023,the number of laboratories participating in Chongqing′s troponin POCT EQA increased from 36 to 88,the number of instrument brand groupings used increased from none to 8,and the qualified rate of each batch of laboratories increased from the lowest 26.32%to the highest 89.77%.However,there was still a large difference in the target values of each instrument brand grouping.The variable coefficients of grouped target value for each batch varied from 44.72%to 105.69%in 2023.Conclusion The participation rate and detection level of Chongqing cardiac troponin POCT EQA needs to be improved,and troponin POCT should be continuously included in EQA plan to regularly monitor the detection quality of this project in the whole city,so as to provide rapid and reliable guarantee for clinical diagnosis and treatment.
