实验室检验质量管理工作中LIMS系统对检验回报合格率的影响

Impact of LIMS on test return pass rates in laboratory test quality management efforts

目的分析实验室检验质量管理工作中应用实验室信息管理系统(Laboratory Information Management System,LIMS)对检验回报合格率存在的影响。方法从本实验室于2022年1月-2023年12月进行检验的标本中选取328份,根据时间分为常规组(2022年1月-2022年12月,常规检验质量管理)、观察组(2023年1月-2023年12月,通过LIMS系统完成检验质量管理),各164份。比较两组标本检验报告情况、不良事件发生情况及实验室工作人员满意度。结果对比两组标本检验报告情况,观察组危急值回报率(95.73%)、危急值报告及时率(96.95%)、检验回报合格率(97.56%)均更高(χ^(2)=6.821,4.525,5.878,P<0.05);组间不良事件发生率对比,观察组(3.05%)更低(χ^(2)=4.525,P<0.05);相较于LIMS系统实施前,实施后实验室工作人员工作效率[(9.12±0.55)分]、管理效果[(9.16±0.57)分]、风险把控[(9.27±0.54)分]评分均更高(t=2.369,2.270,2.291,P<0.05)。结论在LIMS系统下开展实验室检验质量管理工作,可提高检验回报合格率、危急值回报率及危急值回报及时率,降低不良事件发生风险,实验室工作人员管理满意度随之提高,实践价值显著。

Objective to analyze the impact of the application of Laboratory Information Management System(LIMS)in laboratory test quality management on the existence of test return pass rate.Methods 328 specimens were selected from the specimens tested in our laboratory from January 2022 to December 2023,and were divided into routine team(January 2022-December 2022,routine quality management of tests)and survey team(January 2023-December 2023,quality management of tests completed by LIMS system)according to the time,with 164 specimens in each team.Comparison of specimen test reporting,adverse events and laboratory staff satisfaction among the two teams.Results Comparing the test reporting of specimens in the two teams,the critical value return rate(95.73%),the timely rate of critical value reporting(96.95%),and the qualified rate of test return(97.56%)were higher in the survey team(χ^(2)=6.821,4.525,5.878,P<0.05);and in the comparison of the incidence rate of adverse events among the teams,the survey team(3.05%)was lower(χ^(2)=4.525,P<0.05);compared with before the implementation of LIMS system,the scores of laboratory staff efficiency[(9.12±0.55)points],management effectiveness[(9.16±0.57)points],and risk control[(9.27±0.54)points]were higher after the implementation(t=2.369,2.270,2.291,P<0.05).Conclusion Laboratory test quality management under LIMS can improve test return pass rate,critical value return rate and critical value return timely rate,reduce the risk of adverse events,and improve the satisfaction of laboratory staff management,with significant practical value.
