Construction and improvement of lab automation system in emergency lab / 中华检验医学杂志

ABSTRACT

Objective:By exploring a construction and improvement system for total lab automation in emergency lab, this work aims to improve the success rates of project implementation and the effective utilization of medical resources.Methods:Firstly, clarify the short board of current solution and determine the configuration of the TLA solution which include the number of pre-analytic, post-analytic modules and analyzers by workflow and data analysis which based on the data from 16th to 22nd September 2019. Secondly, define the basic principles and design the optional solutions. Thirdly, determine the final solution based on the simulation results. Fourthly, evaluate the effectiveness of the solution by comparing the turnaroud time (TAT) before and after implementation.Result:We upgrade the system to improve the automation level of the track by add 1 online centrifuge module and upgrade the capacity of online storage module from 9 000 samples to 15 000 samples, and increase the throughput of the clinical chemistry analyzers form 2 500 tests/h to 5 400 tests/h and immunoassay analyzers from 668 tests/h to 1 320 tests/h with no more space. The 95th percentile TAT (from sample check in to validation) have 33% reduction on the premise of 9% increase on the workload of clinical chemistry and immunoassay, and it is highly consistent with the results obtained by data simulation whose 95th percentile TAT is 67 min.Conclusion:Good uasge of workflow and data analysis in the stage of solution design can help to ensure that the result can meet the expectations of the clinicians and effective utilization of medical resources.
