Abstract:
Objective:To explore the application value of intelligent assembly line in emergency examination.Methods:A retrospective study was carried out by collecting the data from emergency examination in Tongji Hospital affiliated to Tongji University from June 24 to 28, 2019, to July 24 to 28, 2023.The changes of sample size before and after intelligent pipeline application (with pneumatic transmission device), and the median and 90th percentile( P90) of pre-test turnaround time (TAT) were compared to collect and analyze the quality control related data of the same batch of quality control products before and after using intelligent assembly line automatic quality control; The median TAT and the 90th percentile in the laboratory were analyzed and compared before and after the application of the intelligent pipeline automatic audit rules Statistical enabling of intelligent pipeline-based real-time quality control (PBRTQC) function for patient samples and quality control-based indoor quality control mode for out-of-control detection efficacy. The normal distribution data were analyzed by two independent samples t-test, and the skew distribution data were analyzed by Mann-whitney U test. Results:After the operation of the intelligent assembly line pneumatic transmission device, TAT decreased from 27.1(18.0, 47.7) min to 24.3(15.2, 34.9) min, with a significant difference ( Z=-9.173, P<0.001); There was no significant difference in the indoor quality control results of potassium (K), sodium (NA), Alanine transaminase (Alt), glucose (Glu), total protein (TP) and UREA before and after the implementation of automatic quality control (P>0.05), the consumption of dry biochemical quality control products was reduced from 750 μl/time to 600 μl/time, and the use amount was reduced by 20%. The operation time of quality control was reduced from 30 min/time to 20 min/time, the time was saved by 33.3%, the number of quality control personnel and the walking distance of personnel were significantly reduced, and the detection rate of out-of-control was increased from 0.82% to 0.98% after the development of PBRTQC function. After using the intelligent pipeline automatic audit system, the TAT in the laboratory decreased from 37.1(21.3, 49.2) min to 34.4(16.5, 46.3) min before using the automatic audit function, with significant difference ( Z=-10.062, P<0.001); The median TOTAT and TAT decreased from 56.7.45.8, 102.5) min, 37.4(21.5, 49.6) min to 53.3(42.1, 98.3) min, 33.2.16.4, 47.9) min respectively, and the difference was significant ( Z=-7.176 and -8.245, P<0.001); The P90 of ToTAT and TAT decreased by 18.1% and 17.0%, respectively, and the percentage of sample timeout decreased by 65.5% and 92.1%, while the rate of timely notification of critical values increased from 82.5% to 99.3%. Conclusion:The application of an intelligent emergency pipeline can significantly shorten the test sample turnaround time, and effectively improve the quality and efficiency of emergency testing.
