摘要
目的调查陕西省临床实验室检验标本周转时间(TAT),为实验室质量改进提供依据。方法实验室在线填报4个专业(生化、免疫、血尿粪常规、凝血)急诊和住院标本的检验前和实验室内TAT的第90百分位数;用Excel 2007和SPSS 17.0软件对回报数据进行统计分析;两组数据比较用Mann-Whitney U检验,多组数据比较用Kruskal-Wallis H检验。结果共发放调查表267份,实验室填报率91.0%;其中,完整填写标本TAT的实验室138家。4个专业急诊标本检验前TAT差异无统计学意义(P>0.05),大于85%实验室集中在45 min内;4个专业住院标本检验前TAT差异有统计学意义(P<0.05),80%实验室集中在120 min内,血尿粪常规标本的TAT较免疫稍短;无论急诊还是住院标本,二级医院实验室的4个专业检验前TAT均小于三级医院(P<0.05)。无论是急诊还是住院标本,4个专业的实验室内TAT差异均有统计学意义(P<0.05);血尿粪常规标本最短,其次是凝血,生化和免疫标本最长;80%实验室的生化、免疫、血尿粪常规、凝血的急诊标本实验室内TAT依次集中在30～120 min、30～180 min、<60 min、15～120 min;80%实验室的血尿粪常规和凝血的住院标本实验室内TAT分别集中在120 min和180 min内,而20%实验室的生化和免疫的住院标本实验室内TAT分别≥240 min和≥300 min;无论急诊还是住院标本,两个等级医院实验室内标本TAT之间差异均无统计学意义(P>0.05)。结论陕西省临床实验室检验标本TAT差异较大,部分实验室需要优化标本周转环节,缩短标本TAT。
Objective To investigate the turnaround time (TAT) of clinical laboratory specimens in Shaanxi Province, and provide evidence for improving quality of laboratories. Methods The 90th percentiles of pre-analytical TAT and intra-laboratory TAT of emergency and inpatient specimens from four majors, such as biochemistry, immunology, blood-urine-faces routines and blood coagulation, were filled in by laboratories on-line, and the returned data were analyzed by Excel 2007 and SPSS 17.0 software. The comparison of the data between two groups was performed with Mann-Whitney U test, and that from multiple groups by Kruskal-Wallis H test. Results A total of 267 questionnaires were issued, and 91.0% of laboratories finished the fill-in. Among them, 138 laboratories filled in the specimens′ TAT completely. There was no statistical difference in pre-analytical TAT of emergency specimens from four majors ( P > 0.05 ), and the pre-analytical TAT was within 45 minutes in more than 85% of laboratories. There was significant difference in pre-analytical TAT of inpatient specimens from four majors ( P <0.05), and the pre-analytical TAT was within 120 minutes in 80% of laboratories. The specimens′ TAT of blood-urine-faces routines was slightly shorter than that of immunology. No matter emergency or inpatient specimens, the pre-analytical TAT of four majors in the laboratories of the second-level hospitals was less than that in the third-level hospitals ( P <0.05). Whether emergency or inpatient specimens, there were significant differences in the intra-laboratory TAT of four majors ( P <0.05). The intra-laboratory TAT of blood-urine-faces routines was the shortest, followed by that of blood coagulation and biochemistry, and that of immunology was the longest. The intra-laboratory TATs of emergency specimens for biochemistry, immunology, blood-urine-faces routines and blood coagulation were 30-120 minutes, 30-180 minutes, within 60 minutes and 15-120 minutes respectively, in 80% of laboratories. The intra-laboratory TATs of inpati
