摘要:

药物警戒数据库包括涉及药物和不良事件(AE)的多份病例报告。一些方法始终用于突出显示所有信号,即药物与AE之间的所有统计学显著相关性。这些方法适用于验证涉及一种或多种药物和AE(例如:综合征或相互作用)的更复杂关系,但不解决它们的识别问题。我们提出了一种基于形式概念分析(FCA)的方法,这些关系的提取与非线性措施。该方法可识别作为潜在信号、综合征或相互作用的所有药物和AE。与之前在无FCA的情况下进行重复性分析的经验相比,添加FCA对于识别与合并用药相关的假阳性更有效。

英文摘要:

The pharmacovigilance databases consist of several case reports involving drugs and adverse events (AEs). Some methods are applied consistently to highlight all signals, i.e. all statistically significant associations between a drug and an AE. These methods are appropriate for verification of more complex relationships involving one or several drug(s) and AE(s) (e.g; syndromes or interactions) but do not address the identification of them. We propose a method for the extraction of these relationships based on Formal Concept Analysis (FCA) associated with disproportionality measures. This method identifies all sets of drugs and AEs which are potential signals, syndromes or interactions. Compared to a previous experience of disproportionality analysis without FCA, the addition of FCA was more efficient for identifying false positives related to concomitant drugs.
