Data analysis with popular statistical toolchains like R usually needs to be performed on "flat tables" (so-called dataframes). However, data exchange is often done with FHIR, a format that is based on a hierarchical data model. In this paper, we want to present our tool FhirExtinguisher, which tackles the problems of loading FHIR data into statistical tools by extending the FHIRSearch API with an additional projection layer using FHIRPath. This projection layer can be used to select the data elements of interest and create a CSV file, which can be easily read as dataframe by almost any statistical toolchain.
使用诸如R等流行统计工具链进行数据分析通常需要在“扁平表”（即所谓的数据框）上执行。然而，数据交换通常使用FHIR进行，FHIR是一种基于分层数据模型的格式。在本文中，我们想介绍我们的工具FhirExtinguisher，它通过使用FHIRPath扩展FHIRSearch API并添加一个投影层来解决将FHIR数据加载到统计工具中的问题。这个投影层可用于选择感兴趣的数据元素并创建一个CSV文件，几乎任何统计工具链都可以轻松地将其读取为数据框。
