Analysis of external quality assessment for cardiac troponin POCT in Chongqing from 2018 to 2023
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 cardi-ac 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.Re-sults From 2018 to 2023,the number of laboratories participating in Chongqing's troponin POCT EQA in-creased from 36 to 88,the number of instrument brand groupings used increased from none to 8,and the quali-fied 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 coeffi-cients of grouped target value for each batch varied from 44.72%to 105.69%in 2023.Conclusion The par-ticipation rate and detection level of Chongqing cardiac troponin POCT EQA needs to be improved,and tropo-nin POCT should be continuously included in EQA plan to regularly monitor the detection quality of this pro-ject in the whole city,so as to provide rapid and reliable guarantee for clinical diagnosis and treatment.
