摘　　要：目的比较2019年与2018年检验科标本退检率间的差异,制订检验前标本质量控制的整改措施,加强分析前质量控制。方法从我院LIS系统中导出2018年总送检标本1720847例,其中退检标本1866例;2019年总送检标本1838588例,其中退检标本1234例,按照卫生部要求的监测指标、标本类型、检验项目、月份分组,分别统计各组退检标本例数,计算退检率,卡方比较2019年与2018年各组间退检率差异。结果2019年与2018年比较,总标本退检率显著下降,差异有统计学意义(χ^(2)=174.392,P<0.05);卫生部要求的监测指标组,抗凝标本凝集、标本采集量错误、标本容器错误、标本类型错误和其他类型错误间差异有统计学意义(P<0.05);标本类型组,血标本(抗凝血)、血标本(非抗凝血)、微生物培养间差异有统计学意义(P<0.05);检验项目组,血常规、生化免疫、血气标本退检率位居前三,退检率差异均有统计学意义(P<0.05);月份组,1—6月、11—12月退检率间差异有统计学(P<0.05)。结论增强护士人员的培训工作;加强实习护士的带教工作;增强患者自留标本的宣教工作;完善检验标本采集手册;联合护理部做好整改措施;同时加强检验科与临床科室的有效沟通,检验科适时协助指导临床采集标本等措施对降低标本退检率有极大的帮助。Objective To compare the differences of returned samples in the department of clinic laboratory between 2019 and 2018,formulate the rectification measures for sample quality control before examination,and strengthen the quality control before analysis.Methods A total of 1720847 samples,were extracted from LIS system of our hospital in 2018,including 1866 returned samples.In 2019,1838588 samples were submitted,including 1234 returned samples.The rate of returned samples was calculated according to the monitoring indicators,specimen types,inspection items and months required by the Ministry of Health.Chi-square method was used to compare the difference between in 2019 and 2018.Results The rate of returned samples in 2019 was significantly decreased(χ^(2)=174.392,P<0.05),compared with that in 2018.In the monitoring index group required by the Ministry of Health,there were significant differences in anticoagulant specimen agglutination,wrong sample collection amount,wrong specimen container,wrong specimen type and other types of errors(P<0.05).In Specimen Type group,there were significant differences in blood samples(anticoagulant),blood samples(non anticoagulant)and microbial culture(P<0.05).In the test item group,there were significant differences in routine blood test,biochemical immune test and blood-gas samples which were the top three in all test items(P<0.05).In the month group,there were significant differences in January to June,also November and December(P<0.05).Conclusion Such measures are helpful to reduce the rate of returned samples as training of nurses,teaching practice nurses,educating patients how to take the specimens,improving the manual of laboratory specimens,taking rectification measures combined with nursing department,and communicating with clinical departments.
