Objective to analyze the impact of the application ofLaboratory Information Management System (LIMS) in laboratory testquality management on the existence of test return pass rate. Methods328 specimens were selected from the specimens tested in our laboratoryfrom January 2022 to December 2023, and were divided into routine team(January 2022-December 2022, routine quality management of tests) andsurvey team (January 2023-December 2023, quality management of testscompleted by LIMS system) according to the time, with 164 specimens ineach team. Comparison of specimen test reporting, adverse events andlaboratory staff satisfaction among the two teams. Results Comparing thetest reporting of specimens in the two teams, the critical value returnrate (95.73%), the timely rate of critical value reporting (96.95%), andthe qualified rate of test return (97.56%) were higher in the surveyteam $\left({{\chi }^{2}={6.821},{4.525},{5.878}, P <{0.05}}\right)$ ; and in thecomparison of the incidence rate of adverse events among the teams, thesurvey team (3.05%) was lower $\left({{\chi}^{2}= {4.525}}\right.$ , $P<{0.05}$ ); compared with before the implementation of LIMSsystem, the scores of laboratory staff efficiency $\lbrack \left({{9.12}\pm {0.55}}\right)$ points], management effectiveness [(9.16±0.57) points], and risk control[(9.27±0.54) points] were higher after the implementation $\left({t ={2.369},{2.270},{2.291}, P<{0.05}}\right)$ . Conclusion Laboratory test qualitymanagement under LIMS can improve test return pass rate, critical valuereturn rate and critical value return timely rate, reduce the risk ofadverse events, and improve the satisfaction of laboratory staffmanagement, with significant practical value.
