急诊生化检验的实验室内标本周转时间影响因素分析

Analysis of influencing factors of intra-laboratory turnaround time in emergency biochemistry tests

目的统计急诊生化标本的实验室内标本周转时间(ILTAT),分析ILTAT的影响因素,采取相应的改进措施,完善服务质量,保障患者医疗安全。方法回顾性统计首都医科大学昌平教学医院2015年6-11月急诊生化标本ILTAT。比较ILTAT≤60min和ILTAT≤120min的检验及时率。着重分析实验室各时间段的ILTAT。结果 ILTAT≤120min(ILTAT1)检验及时率98.8%(8 638/8 743),ILTAT≤60min(ILTAT2)检验及时率为83.7%(7 317/8 743)。ILTAT1不同时间段检验及时率比较,差异无统计学意义(χ~2=3.36,P>0.05)。ILTAT2不同时间段ILTAT比较差异有统计学意义(χ2=134.50,P<0.01)。其中T2(10:01-12:00)检验及时率最高(88.1%),T1(8:01-10:00)检验及时率最低(76.8%),T3(12:01-14:00)、T7(6:01-8:00)这两个时段检验及时率较低,分别为79.4%、80.2%。结论目前本实验室急诊生化ILTAT满足现行的规定要求。通过分析急诊生化ILTAT影响因素,优化工作流程,改善仪器设备及人员配置,提高信息化处理程度,可进一步缩短急诊生化ILTAT,更好地满足临床和患者的需求。

Objective To investigate the intra-laboratory turnaround time（ILTAT）of the emergency biochemistry tests and to analyze the factors influencing ILTAT in order to adopt the corresponding improvement measures for perfecting the service quality and ensuring the patient medical safety.Methods ILTAT of the emergency biochemical specimens in our hospital from June to November 2015 was performed the retrospective statistics for comparing the determination timely rate between ILTAT≤60min and ILTAT2 ≤120min.ILTAT at different time periods in laboratory was emphatically analyzed.Results The determination timely rate of ILTAT ≤120min（ILTAT 1）was 98.8%（8638/8743）,and which of ILTAT ≤60min（ILTAT 2）was 83.7%（7317/8743）.The determination timely rate of ILTAT1 had no statistical difference among different time periods（χ2=3.36,P〉0.05）.The determination timely rate of ILTAT2 had statistical difference among different time periods（χ2=134.5,P〈0.01）.The determination timely rate of T 2（10：01-12：00）was highest（88.1%）,which of T1（8：01-10：00）was lowest（76.8%）,which of T3（12：01-14：00）and T7（6：01-8：00）was lower（79.4% and 80.2% respectively）.Conclusion At present,ILTAT in our laboratory meets the requirements of the current regulations.Analyzing the ILTAT influencing factors in the emergency biochemistry,optimizing the workflow,improving the equipments and staffing allocation and improving the degree of information processing can further shorten the emergency biochemical ILTAT,and better meet the clinical and patient′s needs.
