实验结果回报时间分析

Turnaround time analysis of experimental results

目的:分析血常规五分类标本、生化标本、免疫标本的实验结果回报时间(TAT),探讨影响TAT延长的可能因素。方法:通过实验室信息系统(LIS)分析血常规五分类标本、生化标本、免疫标本的TAT,计算从采集到审核各阶段的时间与ISO15189实验室实验TAT目标值对比,分析各阶段的影响因素。结果:快速急诊标本TAT不符合ISO15189实验室TAT目标值,门诊标本、住院标本均符合ISO15189实验室TAT目标值。影响实验结果 TAT延长的主要因素为快速急诊标本未及时处理、标本量处于高峰期、检测项目或者过程过于复杂繁琐、仪器故障与保养、维护影响标本检测、运送人员和其他人员素质不够,与临床沟通不够等。结论:门诊和住院的标本符合ISO15189实验室TAT目标值,满足了临床和病人的需要。对未符合ISO15189实验室管理采取急诊标本进行优先处理,保证检验质量和临床需求。

Objective：To search the better method and technique to reduce turnaround time（TAT） through analyzing experiment TATs of blood routine specimens in five categories, biochemical specimens and immune specimens. Methods ： TAT of the specimens were analyzed using laboratory information system（LIS） and the results of each stage were compared with those of ISO15189 laboratory, the factors of each stage were discussed. Results： The TATs of emergency blood routine specimens did not meet the target value of TAT of ISO15189 lab,while the outpatient and inpatient specimens were in line with TAT target value. The main factors that caused long experiment TATs were：the delay of processing fast emergency specimens, the peak of specimen volume, the complexity of testing process, and the analyzer maintenance and poor operator training. Conclusions ：The test results of the samples from outpatient and inpatient department were in accordance with TAT target values of ISO15189 laboratory. For the samples from emergency department which were not in accordance with TAT target values ,more attenion should be paid to them and strengthen our clinical laboratory management.
