How do I get access to MIMIC?

Getting access to MIMIC data requires completing human subjects training and signing a data use agreement. Here is the step-by-step process:

Step 1: Complete PhysioNet Credentialing

  1. Create a PhysioNet account at physionet.org
  2. Complete the credentialing process:
    • Take the required training course in human subjects research
    • Provide your institutional affiliation
    • Submit reference information (required for students/postdocs)
  3. Wait for approval. Please be patient, we try to process applications within 1-2 weeks.

Students and Postdocs: You must provide your supervisor’s contact information as a reference. Do not list yourself as a reference.

Step 2: Sign the Data Use Agreement

Once credentialed:

  1. Log in to your PhysioNet account
  2. Navigate to the dataset page you need:
  3. Review and sign the Data Use Agreement (DUA)
  4. Download or access data through cloud platforms

Step 3: Choose Your Access Method

  • Google Cloud (BigQuery): Easiest for SQL queries
  • AWS: Available for MIMIC-III
  • Google Cloud Storage: Direct access to data within GCP

Local Download

  • Download individual CSV files
  • Set up a local PostgreSQL database
  • Requires more setup but provides full control

Common Questions

How long does credentialing take?

Typically 1-2 weeks if all information is complete. Incomplete applications may be delayed or rejected.

Can I access data immediately after signing the DUA?

Yes, for cloud platforms. Local download may take additional time depending on file sizes.

Do I need separate access for each dataset?

Yes, you need to sign separate DUAs for MIMIC-III, MIMIC-IV, MIMIC-CXR, MIMIC-IV-Note, MIMIC-IV-ED, and MIMIC-IV-ECG.

Troubleshooting

Application Rejected

  • Ensure all required fields are completed
  • Provide a valid institutional email address (not required, but helpful)
  • Include the correct CITI training: make sure it is “Data or Specimens Only Research”
  • Include the CITI Completion Report, not just the certificate
  • Include proper reference information
  • Contact credentialing at PhysioNet if issues persist

Can’t Find Reference Information

  • Use your supervisor or department head
  • Must be someone who can verify your affiliation
  • Should not be yourself or a peer student
