Abstract

Introduction: The aim of the study was to determine the current state of laboratory's extra-analytical phase performance by calculating preanalytical and postanalytical phase quality indicators (QIs) and sigma values and to compare obtained data according to desired quality specifications and sigma values reported by The International Federation of Clinical Chemistry and Laboratory Medicine (IFCC) Working Group - Laboratory errors and Patient Safety.

Materials and methods: Preanalytical and postanalytical phase data were obtained through laboratory information system. Rejected samples in preanalytical phase were grouped according to reasons for rejection and frequencies were calculated both monthly and for 2019. Sigma values were calculated according to "short term sigma" table.

Results: The number of rejected samples in laboratory was 643 out of 191,831 in 2019. Total preanalytical phase rejection frequency was 0.22%. According to the reasons for rejection, QIs and sigma values were: "Samples with excessive transportation time": 0.0036 and 5.47; "Samples collected in wrong container" 0.02 and 5.11. In December, QIs and sigma values were: "Samples with excessive transportation time": 0.01 and 5.34; "Samples collected in wrong container": 0.03 and 4.98. The postanalytical QIs and sigma values were: "Reports delivered outside the specified time": 0.34 and 4.21; "Turn around time of potassium": 56 minute and 3.84, respectively. There were no errors in "Critical values of inpatients and outpatients notified after a consensually agreed time".

Conclusions: Extra-analytical phase was evaluated by comparing it with the latest quality specifications and sigma values which will contribute to improving the quality of laboratory medicine.

根据IFCC实验室错误和患者安全规范对临床生物化学实验室分析前和分析后阶段进行评估。
本研究的目的是通过计算分析前和分析后阶段质量指标(QIs)和sigma值来确定实验室分析外阶段性能的现状,并根据国际临床化学和检验医学联合会(IFCC)实验室错误和患者安全工作组报告的期望质量规范和sigma值来比较获得的数据。材料和方法:通过实验室信息系统获取分析前和分析后的相数据。根据拒收原因对预分析阶段的拒收样本进行分组,并计算每月和2019年的拒收频率。Sigma值根据“短期Sigma”表计算。结果:2019年实验室拒收样品191831份,拒收样品643份。总分析前相抑制频率为0.22%。根据拒收原因,QIs和sigma值分别为:“运输时间过长的样品”分别为0.0036和5.47;“样品装错容器”0.02和5.11。12月的QIs和sigma值分别为:“运输时间过长的样本”分别为0.01和5.34;“样品装错容器”:0.03和4.98。分析后的QIs和sigma值分别为:“在规定时间外提交的报告”:0.34和4.21;“钾的周转时间”分别为56分钟和3.84分钟。在“住院病人和门诊病人在双方同意的时间后通知的临界值”中没有错误。结论:通过与最新质量规范和sigma值的比较,对分析外相进行评价,有助于提高检验医学质量。

期刊介绍: Biochemia Medica is the official peer-reviewed journal of the Croatian Society of Medical Biochemistry and Laboratory Medicine. Journal provides a wide coverage of research in all aspects of clinical chemistry and laboratory medicine. Following categories fit into the scope of the Journal: general clinical chemistry, haematology and haemostasis, molecular diagnostics and endocrinology. Development, validation and verification of analytical techniques and methods applicable to clinical chemistry and laboratory medicine are welcome as well as studies dealing with laboratory organization, automation and quality control. Journal publishes on a regular basis educative preanalytical case reports (Preanalytical mysteries), articles dealing with applied biostatistics (Lessons in biostatistics) and research integrity (Research integrity corner).
