MIMIC-IV Clinical Database Demo on FHIR

Interoperability of healthcare data has become increasingly important given the increase in deployment of data driven algorithms in clinical settings. The Fast Healthcare Interoperability Resources (FHIR) standard has emerged as a promising mechanism to share healthcare data across vendors in real-time and batch settings. Real-world datasets available in FHIR would accelerate research and development of data-driven algorithms. Existing datasets in FHIR are primarily synthetic, and cover a limited number of resources. To address this gap, we have reformatted the Medical Information Mart for Intensive Care (MIMIC)-IV Clinical Database Demo into FHIR. The MIMIC clinical databases have received wide adoption and the constituent data are understood by the community. As much as possible, we adhered to the base resources with minimal extensions. Alongside the dataset, we publish openly available code allowing researchers to quickly build upon our work. Translating MIMIC-IV into FHIR provides a benchmark dataset for institutions to experiment with FHIR based tools, and we hope this resource supports adoption and use of FHIR.
