After the introduction of modern laboratory instruments and information systems, preanalytic phase is the new field of battle. Errors in preanalytical phase account for approximately half of total errors in clinical laboratory. The objective of this study was to share an experience of an education program that was believed to be successful in decreasing the number of rejected samples received from the Emergency Department (ED).
An education program about laboratory procedures, quality requirements in the laboratory, patient and health-care worker safety was planned by the quality team to be performed on 36 people who were responsible for sample collection in the ED. A questionary which included 11 questions about the preanalytic phase was applied to all the attendees before and after training. The number of rejected samples per million was discovered with right proportion account over the number of accepted and rejected samples to laboratory after and before the training period.
Most of the attendees were nurses (n: 22/55%), with over 12 years of experience in general and 2-4 years experience in the ED. Knowledge level of the attendees was calculated before training as 58.9% and after training as 91.8%. While the total rate of sample rejection before training was 2.35% (sigma value 3.37-3.50), the rate after training was 1.56% (sigma value 3.62-3.75).
Increasing the knowledge of staff has a direct positive impact on the preanalytic phase. The application of a pre-test was observed to be a feasible tool to shape group specific education programs.
在引入现代实验室仪器和信息系统之后，分析前阶段成为了新的“战场”。分析前阶段的误差约占临床实验室总误差的一半。本研究的目的是分享一项教育计划的经验，该计划被认为在减少从急诊科（ED）接收的不合格样本数量方面取得了成功。
质量团队制定了一项关于实验室程序、实验室质量要求、患者和医护人员安全的教育计划，计划对36名负责在急诊科采集样本的人员进行培训。在培训前后，对所有参与者进行了一份包含11个关于分析前阶段问题的问卷调查。通过正确计算培训前后送到实验室的合格和不合格样本数量的比例，得出每百万样本中的不合格样本数量。
大多数参与者是护士（n = 22/55%），一般有超过12年的工作经验，在急诊科有2 - 4年的工作经验。参与者的知识水平在培训前计算为58.9%，培训后为91.8%。培训前样本拒收的总率为2.35%（西格玛值3.37 - 3.50），培训后为`1.56%（西格玛值3.62 - 3.75）。
提高工作人员的知识水平对分析前阶段有直接的积极影响。预测试的应用被认为是制定针对特定群体的教育计划的可行工具。
