微生物标本类型的实验室信息系统设置研究

Study on laboratory information system setting of microbiology specimen types

目的在实验室信息系统(LIS)上建立微生物检验主要标本类型的体系,减少微生物标本送检类型与申请类型的不一致,实现微生物分析前质量控制的管理目标。方法收集2015年1月1日至1月31日的3 304份微生物送检标本,在LIS系统中设置主要标本类型微生物项目申请程序后,统计6月20-24日1 532份微生物送检标本,比较设置前后的标本类型错误率,后于7月9-13日,8月10-15日分别再次收集微生物送检标本1 635份和1 340份;持续观察错误率的变化,比较设置前后错误率是否有统计学差异,比较设置前后LIS系统特点。结果设置前微生物送检标本标本类型错误率为的4.6%(152/3 304)。设置后,微生物送检标本类型错误率为1.3%(20/1532),与设置前校差异有统计学意义(χ~2=31.224,P<0.05),持续观察阶段微生物送检标本类型错误率保持在较低水平,分别为1.04%(17/1635)和0.9%(13/1340),与设置前比较差异均有统计学意义(P<0.05)。结论重新设置的LIS系统,降低了微生物标本类型的错误率,有效地提高了工作效率,达到微生物分析前质量控制的指标。

Objective The microbiology specimen types were various and complex,the system of main specimen types in microbiological detection was established under the laboratory information system（LIS）for realizing the management target of quality control before microbiological analysis.Methods A total of 3 304 submitted microbiological samples were collected from January 1to 31 in 2015.After setting the microbiological item application procedure of main specimen types in LIS,1 532 submitted microbiological specimens from June 20 to 24were performed the statistics.The error rates of specimen types were compared before and after setting.Then 1 635 and 1 340 submitted microbiological specimens were re-collected form July 9to 13 and August 10 to 15;the change of error rates was continuously observed for comparing whether the statistical difference of error rates existing between before and after setting.Results The error rate of submitted microbiological specimens before setting was 4.6%（152/3 304）,which after setting was 1.3%（20/1 532）（χ~2=31.224,P〈0.001）,which during the continuous observation period maintained the lower level of 1.04%（17/1 635）,χ~2=39.658,P〈0.001）and 0.9%（13/1 340,χ~2=34.673,P〈0.001）.Conclusion Re-setting the LIS reduces the error rate of microbiological specimen type,effectively increase the working efficiency and reaches the quality control index before microbiological analysis.
