本研究展示了使用实验室信息系统 (LIS) 数据对局部参考区间 (RI) 的长期监测方法. 在±1/2的总允许误差 (TEA) 范围内分析正比率可以确保在系统更改后的RI适用性.
科学领域:
- 临床化学 临床化学
- 实验室医学 实验室医学
- 医疗信息学 医疗信息学
背景情况:
- 在实验室系统过渡后,保持参考区间 (RIs) 的本地适用性至关重要.
- 实验室信息系统 (LIS) 数据为监测RI性能提供了宝贵的资源.
- 对正比率的统计分析可以评估RI的长期有效性.
研究的目的:
- 评估本地参考区间 (RI) 适用性的长期监测可行性.
- 使用实验室信息系统 (LIS) 数据建立评估RI性能的方法.
- 为了验证用于检测RI差异的统计方法,检测后系统过渡.
主要方法:
- 分析了2018-2020年阳性率的变化系数 (CV),使用±1/2总允许误差 (TEA).
- 评估了2022-2024年的阳性率与计算的±1/2 TEA范围相比,以确定偏差.
- 在有不规律月经的患者中研究了益乳素的结果,以排除年龄和样本采集时间对差异的影响.
主要成果:
- 2018-2020年阳性率CV为11.41%,在±1/2 TEA范围内.
- 从2022年至2024年间的积极率最初超过了±1/2 TEA范围,但在新的RI中是可以接受的.
- 年龄和采样时间被排除为不一致的原因;这两个时期的数据显示在±1/2 TEA范围内相互一致.
结论:
- 从LIS数据中得出的±1/2 TEA范围周围的平均阳性率是有效的,用于长期评估局部RI适用性.
- 该方法提供了一种可靠的方法,用于在实验室检测系统过渡后确保RI准确性.
- 对LIS数据的分析提供了一个可行和可靠的战略,用于持续监测RI性能.

Prediction Intervals
However, the point estimate is most likely not the exact value of the population parameter, but close to it. After calculating point estimates, we construct interval estimates, called confidence intervals or prediction intervals. This prediction interval comprises a range of values unlike the point estimate and is a better predictor of the observed sample value, y.
Local Anesthetics: Common Agents and Their Applications
Cocaine is an ester of benzoic acid and methylecgogine. It is used to anesthetize and vasoconstrict locally. Currently, it is used primarily for topical applications. It is beneficial for surgeries on the upper respiratory tract, providing anesthesia and shrinking the mucosa. Cocaine in the form of cocaine hydrochloride is...
