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.

快速医疗保健互操作性资源（Fast Healthcare Interoperability Resources，FHIR）已成为医疗数据交换领域成熟可靠的标准。为探索FHIR在数据协调流程中的应用，我们将重症监护医学信息库IV（Medical Information Mart for Intensive Care IV，MIMIC-IV）与MIMIC-IV急诊数据库（MIMIC-IV Emergency Department，MIMIC-IV-ED）转换为FHIR格式。我们对基础FHIR进行扩展，以对MIMIC-IV中的信息进行编码，并尽可能遵循US Core v4.0.0标准，以最少的额外处理量保留FHIR格式的数据。针对MIMIC-IV数据集，共创建了24个FHIR配置文件；针对MIMIC-IV-ED数据集，则额外创建了6个FHIR配置文件。必要时，所有MIMIC术语均被转换为代码系统与值集。我们期望，转换为FHIR格式的MIMIC-IV能够实现数据的有效重构，为数据协调、互操作性及其他研究领域的应用提供支撑。
