MIMIC-IV-Ext-CLIF: MIMIC-IV in the Common Longitudinal ICU data Format (CLIF)

MIMIC-IV-Ext-CLIF is a derived dataset of MIMIC-IV v3.1, transformed into the
Common Longitudinal ICU data Format (CLIF). CLIF is an open-source critical
care data model developed by a consortium of more than 10 US academic medical
centers to standardize intensive care unit (ICU) data for multi-center
research. While CLIF has demonstrated value in federated research settings,
access has been limited to consortium members with institutional electronic
health record (EHR) data. This dataset addresses that gap by providing CLIF-
formatted data derived from the freely accessible de-identified MIMIC-IV
dataset, enabling researchers worldwide to utilize the CLIF format without
requiring institutional EHR access.

MIMIC-IV-Ext-CLIF contains 14 CLIF tables as of the latest CLIF 2.1.0 version,
covering core demographics (patient, hospitalization), clinical monitoring
(vitals, labs), respiratory support, medication administration, and
specialized ICU interventions (e.g., continuous renal replacement therapy).
The transformation employs a reproducible ETL pipeline with transparent
mapping decisions documented in user-friendly spreadsheets.
