Saving lives with data by providing regulatory-grade safety and effectiveness data.

The gold-standard open-source framework for reproducible clinical data science and EHR analytics.

The MIMIC Code Repository, managed by the MIT Laboratory for Computational Physiology, is the definitive technical framework for processing and analyzing the Medical Information Mart for Intensive Care (MIMIC) databases. In 2026, it serves as the critical infrastructure for fine-tuning medical Large Language Models (LLMs) and validating clinical AI agents. The repository provides a massive library of SQL scripts (PostgreSQL, BigQuery), Python modules, and R packages designed to transform raw, de-identified electronic health records (EHR) into structured, analysis-ready datasets. Its architecture is built around modularity, allowing researchers to calculate complex clinical scores—such as SOFA, SAPS II, and OASIS—directly within the database layer. By providing standardized scripts for data cleaning, cohort selection, and feature engineering, it ensures that clinical AI benchmarks are reproducible across global research institutions. As the healthcare industry shifts toward evidence-based AI, this repository remains the primary bridge between raw hospital data and production-ready predictive models for mortality, sepsis, and resource allocation.

Register for a PhysioNet account and complete the CITI 'Data or Specimens Only Research' training.
Submit a formal request for access to the MIMIC-IV or MIMIC-III datasets via PhysioNet.
Clone the official mimic-code repository from GitHub to your local or cloud environment.
Set up a relational database instance using PostgreSQL 14+ or Google BigQuery.
Run the schema creation scripts located in the 'mimic-iv/buildrepo' directory.
Import the raw MIMIC CSV files into the newly created database tables using the provided 'load.sql' scripts.
Execute the 'concept' scripts to generate high-level clinical abstractions like ventilation status and vasopressor usage.
Configure the Python or R environment with the necessary database drivers (psycopg2 or bigquery-client).
Run the validation test suite to ensure the data counts match the official documentation.
Utilize the 'notebooks' directory to begin exploratory data analysis or model training.
