The MIMIC-II research database (Multiparameter Intelligent Monitoring in Intensive Care) is notable for three factors:  it is publicly and freely available; it encompasses a diverse and very large population of ICU patients; and it contains high temporal resolution data including lab results, electronic documentation, and bedside monitor trends and waveforms.  The database can support a diverse range of analytic studies spanning epidemiology, clinical decision-rule improvement, and electronic tool development.

How to get access

The MIMIC-II database is available under terms of a data use agreement (DUA). Investigators who wish to obtain access to the database are invited to review the DUA and submit an application to PhysioNet.

Applications may require several days for review; please be patient. If your application is approved, we will contact you with instructions for database access.

If you are having problems with the process, please contact us.

Using the database

Once you have received the proper credentials to access our site, you will also gain access to our Mimic Explorer, a collection of online search and query tools. In addition, you will gain access to the project repository where you can see examples of projects which have been carried out using the database. These case-studies will provide an introduction to the types of research which can be performed and contain details pertaining to the project's aims and links to source code.

Documentation for the types of data we have in the database, and how to access and interpret them is available in both HTML and PDF [3MB] formats.

Please note that we will add data to the database, correct mistakes, and update the documentation over the next years. Please check PhysioNet for announcements concerning these updates. We also encourage users to report bugs, provide feedback, feature suggestions and annotations for the data, to help us constantly improve our resource. Our Bug Tracker (use your MIMIC username and password) allows users to provide suggestions, report problems and track progress.
