摘要目的 探讨实验室信息管理系统(LIS)对输血科工作效率和工作误差的影响,以及输血信息化的建设远景.方法 选择2012年1月1日至2013年12月31日,新疆维吾尔自治区乌鲁木齐市新疆军区总医院输血科通过信息管理系统统计的共计26 294份输血资料为研究对象.按照统计输血资料所采用的信息管理系统不同,将其分为LIS使用前组(n=12 759)及LIS使用后组(n=13 535).LIS使用前组的输血资料统计采用“军卫一号”输血与检验管理系统,统计时间为2012年1月1日至12月31日;LIS使用后组输血资料统计采用LIS,统计时间为2013年1月1日至12月31日.信息管理系统统计的输血资料包括工作效率和工作差错发生率2个部分.工作效率指标包括配发血效率、血型检测效率、传染病检测效率等;工作差错发生率包括标本误差率、漏计费误差率、重复计费率、血液过期率.对2组输血资料上述各个指标之间的差异进行统计学比较.结果 ①LIS使用后组的血型检测效率为(33.9±3.5)份/(人·d),传染病检测效率为(80.3±5.1)份/(人·d),分别高于LIS使用前组的(24.3±3.1)份/(人·d)和(60.2±4.5)份/(人·d),并且差异均有统计学意义(t=-10.52、-19.23,P＜0.001).②LIS使用后组的标本误差率、漏计费误差率、重复计费率及血液过期率分别为(0.0300±0.000 3)％、(0.080 0±0.001 8)％、(0.250 0±0.001 9)％及(0.080 0±0.001 5)％,均低于LIS使用前组的(0.940 0±0.002 4)％、(0.960 0±0.003 8)％、(1.030 0±0.004 8)％及(0.480 0±0.005 0)％,并且差异均亦有统计学意义(t=31.06、11.01、6.76、2.97,P＜0.05).结论 LIS可提高输血科工作效率并减少差错,今后输血信息化工作可针对输血流程管理、大数据分析、扁平化管理、质量控制、信息化标准及信息安全等方面继续加强改进.

abstractsObjective To explore the influence of laboratory information system(LIS) on the work efficiency and incidence of work error in department of transfusion,and discuss the prospect of transfusion information construction.Methods From 1st January 2012 to 31st December 2013,a total of 26 294 blood transfusion data were selected as the research objects,which were collected from the Department of Transfusion,General Hospital of Xinjiang Military Region through information management system.According to the different information management systems,the transfusion data were divided into before LIS using group (n=12 759) and after LIS using group (n=13 535).The transfusion data of before LIS using group were collected through blood transfusion and detection management system of No.1 Military Medical Project from 1st January 2012 to 31st December 2012.The transfusion data of after LIS using group were collected through LIS from 1st January 2013 to 31st December 2013.The transfusion data including work efficiency (efficiency of blood type identification,efficiency of blood type detection,efficiency of infectious disease detection,etc.) and incidence of work error (incidence of sample mismatch,incidence of missing charge,incidence of repeated charge,incidence of blood expiration).The differences of above indexes between the two groups were compared by the statistical methods.Results ① The efficiency of blood type identification [(33.9±3.5) copy/(person · d)] and efficiency of infectious disease detection [(80.3 ± 5.1) copy/(person · d] in after LIS using group were higher than those of (24.3 ±3.1) copy/(person · d) and (60.2±4.5) copy/ (person · d) in before LIS using group,respectively.And the differences were statistically significant (t=-10.52,-19.23;P＜0.001).② The incidence of sample mismatch,incidence of missing charge,incidence of repeated charge,incidence of blood expiration in after LISusing group were(0.030 0 ± 0.000 3)％,(0.080 0± 0.001 8)％,(0.2500± 0.001 9)％ and (0.080 0±0.001 5)％ respectively,which were lower than those of (0.940 0±0.002 4) ％,(0.960 0± 0.003 8)％,(1.030 0±0.004 8)％ and (0.480 0±0.005 0)％ in before LIS using group.And the differences were statistically significant (t=31.06,11.01,6.76,2.97;P＜0.05).Conclusions Application of LIS promoted work efficiency and reduced the level of error risk in department of transfusion.Future direction for transfusion informatization should consist of better workflow,big data,flat organization,continued improvement of quality control,information standardization and security of transfusion information.
