MIMIC-IV on FHIR

Fast Healthcare Interoperability Resources (FHIR) has emerged as a robust standard for healthcare data exchange. To explore the use of FHIR for the process of data harmonization, we converted the Medical Information Mart for Intensive Care IV (MIMIC-IV) and MIMIC-IV Emergency Department (MIMIC-IV-ED) databases into FHIR. We extended base FHIR to encode information in MIMIC-IV and aimed to retain the data in FHIR with minimal additional processing, aligning to US Core v4.0.0 where possible. A total of 24 profiles were created for MIMIC-IV data, and an additional 6 profiles were created for MIMIC-IV-ED data. All MIMIC terminology was converted into code systems and value sets, as necessary. We hope MIMIC-IV in FHIR provides a useful restructuring of the data to support applications around data harmonization, interoperability, and other areas of research.

快速医疗互操作性资源（Fast Healthcare Interoperability Resources，简称FHIR）已逐渐成为医疗数据交换的稳健标准。为了探究FHIR在数据调和过程中的应用，我们将重症监护信息市场第四版（Medical Information Mart for Intensive Care IV，简称MIMIC-IV）和MIMIC-IV急诊科（MIMIC-IV-Emergency Department，简称MIMIC-IV-ED）数据库转换为FHIR格式。我们对基本的FHIR标准进行了扩展，以编码MIMIC-IV中的信息，并旨在通过最小化的额外处理，尽可能与US Core v4.0.0标准保持一致，从而在FHIR中保留数据。针对MIMIC-IV数据，我们创建了共计24个配置文件，并为MIMIC-IV-ED数据额外创建了6个配置文件。所有MIMIC术语均按需转换为代码系统和值集。我们期望MIMIC-IV在FHIR中的转换能够为数据调和、互操作性以及其他研究领域提供有益的数据重构。
