PhysioNet
PhysioNet lets users find, share, and reuse health data, with guidance on access to credentialed datasets.
PhysioNetphysionet.orgVisit siteAbout PhysioNet
PhysioNet is a web-based research resource focused on complex physiologic signals, enabling users to find, share, and reuse health datasets, including credentialed restricted collections such as MIMIC-III, MIMIC-IV, and MIMIC-CXR. The platform provides guidance for compliant use of its data, including explicit restrictions on sharing credentialed datasets with third parties via APIs or online services, and recommendations for local LLM deployment or verified zero-data-retention cloud services when using large language models with its data.
Key features
- Find and access credentialed and open health datasets
- Publish and share health research datasets
- Guidance for compliant use of restricted datasets
- Access to MIMIC-III, MIMIC-IV, and MIMIC-CXR datasets
- Support for biomedical and physiological research use cases
Best for: Biomedical and clinical researchers working with physiological or health datasets, including those using large language models for research.
Good for
- Hosts widely used datasets including the MIT-BIH Arrhythmia Database and MIMIC family collections
- Has supported tens of thousands of research papers over 25 years of operation
- Provides clear guidance on compliant data use, including LLM and online service restrictions
Watch out for
- Credentialed restricted datasets cannot be shared with third parties via APIs or online platforms per the Data Use Agreement
- PhysioNet cannot verify external service data handling practices and does not endorse specific platforms
- Many cloud services retain data by default, requiring manual verification of zero-data-retention policies for compliant use

PhysioNet FAQ
Can credentialed MIMIC data be used with third-party LLM APIs or online services?
No, the PhysioNet Credentialed Data Use Agreement explicitly prohibits sharing credentialed data with third parties, including sending it through APIs or using it on online platforms.
What must users verify when using cloud LLM services with MIMIC data?
Users must confirm the service has zero data retention, no use of data for model training, and no human review, as many services retain data by default.
Does PhysioNet endorse specific cloud platforms for use with its data?
No, PhysioNet cannot verify external service data practices and does not endorse or recommend specific platforms.
