急诊科与重症医学科急诊样本周转时间的比较分析

Comparative analysis of stat test turnaround times between emergency department and intensive care unit

目的对急诊科与重症医学科(ICU)急诊样本周转时间(TAT)各时间段进行定位比较分析,为合理缩短急诊样本TAT提供客观依据。方法利用实验室信息系统,统计该院2014年1月1日至3月31日急诊科和ICU急诊血细胞分析和急诊生化项目TAT各时间段的数据,并进行两个科室间急诊样本TAT各时间段的定位比较分析。结果急诊科和ICU急诊血细胞分析TAT阈外值率分别为2.4%和15.1%,急诊生化项目TAT阈外值率分别为12.3%和24.5%。急诊科急诊血细胞分析和急诊生化项目从下达医嘱到样本接收的平均时间分别与ICU急诊血细胞分析和急诊生化项目从样本采集到样本接收的平均时间比较,差异均无统计学意义[(11.2±4.0)min vs.(11.2±4.5)min,P>0.05;(13.2±14.1)min vs.(13.8±9.8)min,P>0.05]。急诊科急诊血细胞分析和急诊生化项目从样本接收到结果报告的平均时间均分别较ICU急诊血细胞分析和急诊生化项目从样本接收到结果报告的平均时间短[(5.8±4.4)min vs.(19.3±12.5)min,P<0.01;(34.4±10.9)min vs.(35.5±13.2)min,P<0.01]。急诊科急诊血细胞分析和急诊生化项目TAT平均时间均分别比ICU急诊血细胞分析和急诊生化项目平均时间短[(17.0±6.2)min vs.(30.5±14.9)min,P<0.01;(46.9±17.2)min vs.(49.3±16.5)min,P<0.01]。结论急诊科急诊血细胞分析和急诊生化项目的 TAT阈值设定较合理,且TAT各时间段得到了较好控制。ICU急诊血细胞分析和急诊生化项目的TAT阈值应重新设定,且ICU急诊样本检验流程应得到优化。

Objective To provide the objective evidence for reducing stat test turnaround time（TAT）reasonably through the comparative analysis of different intervals of stat test TAT between emergency department（ED）and intensive care unit（ICU）.Methods Laboratory information system was used to collect data about blood cell analysis and biochemical profiles of department of emergency and ICU from 1st January to 31 th March,2014,then comparatively analyzing different intervals of stat test TAT between two departments.Results TAT outlier rates of stat CBC tests ordered by ED and ICU were 2.4% and 15.1%,and that of stat biochemical profiles ordered by ED and ICU were 12.3%and 24.5%,respectively.there were no significant differences in mean times between order-to-receipt of stat CBC tests and biochemical profiles ordered by ED and collection-to-receipt of stat CBC tests and biochemical profiles ordered by ICU [（11.2±4.0）min vs.（11.2±4.5）min,P〉0.05;（13.2±14.1）min vs.（13.8±9.8）min,P〉0.05].ED had significantly shorter mean time of receipt-to-report than ICU for stat CBC tests and biochemical profile[（5.8±4.4）min vs.（19.3±12.5）min,P〈0.01;（34.4±10.9）min vs.（35.5±13.2）min,P〉0.01].The TAT mean times of stat CBC tests and biochemical profiles ordered by ED were shorter than those ordered by ICU [（17.0±6.2）min vs.（30.5±14.9）min,P〈0.01;（46.9±17.2）min vs.（49.3±16.5）min,P〈0.01].Conclusion The ED TATs for CBC tests and biochemical profiles are reasonably set,and each interval of the ED TATs is well controlled.The ICU TATs for CBCs and biochemical profiles should be reset,and the process of stat test for ICU should be optimized.
