许多血液样本标签错误的事件没有被发现. 这项研究发现,未识别的样本错误标签的比例高于先前发现的,突出了临床实验室中关键的患者安全问题.
科学领域:
- 临床病理学 临床病理学
- 实验室医学 实验室医学
- 患者安全 患者安全
背景情况:
- 样本错误标记是一个关键的患者安全错误,难以检测.
- 目前用于估计样本错误标记的方法可能无法识别所有错误标记样本的情况.
研究的目的:
- 量化患者样品标签上的差异率.
- 为了估计未识别的 (隐性) 样本错误标签的流行率.
主要方法:
- 在多个完整血清样本上进行了血型鉴定,这些样本共享相同的患者标签,以确定差异.
- 鉴定到的样本错误标签的比率是根据研究期间计算的.
主要成果:
- 观察到的不一致率为每1000个标本3.17个.
- 这种差异率表明有大量未识别的标签错误的样品.
- 鉴定的样本错误标签率为每1000个标本1.15个.
结论:
- 错误标记的标识标识的标本可能只代表所有错误标记的样本的一部分.
- 这些发现表明,在标本识别中的实验室错误比以前认为的更为普遍.
- 这些结果对整个机构的实验室质量控制和患者安全协议有影响.

Errors In Hypothesis Tests
Types of Errors: Detection and Minimization
Absolute error in a measurement is the numerical difference from the true or central value. Relative error is the ratio between absolute error and the true or central value, expressed as a percentage.
Errors can be classified by source, magnitude, and sign. There are three types of errors: systematic, random, and gross.
Systematic or...
Systematic Error: Methodological and Sampling Errors
Sampling errors originate from improper sampling methods or the wrong sample population. These errors can be minimized by refining the sampling strategy. Defective instruments or faulty calibrations are the sources of instrumental...

Accuracy and Errors in Hypothesis Testing
In hypothesis testing, the probability of making a Type I error, denoted as α, is commonly set at 0.05. This significance level indicates a 5%...
