The STS Participant User File (PUF) Research Program allows analysis of national-scale de-identified data from the Database at investigators’ institutions. The PUF Program is unique in many respects and was designed primarily as an option for investigators to pose research questions, quickly obtain quality data, analyze these data themselves, receive feedback, and develop their efforts into abstracts and manuscripts. Read more about the PUF Program.
PUF applications are being accepted for data in the Adult Cardiac Surgery Database, General Thoracic Surgery Database, Congenital Heart Surgery Database, and the Intermacs Database.

To avoid issues with scientific overlap, we highly encourage investigators to share their proposed topic of study with Research Center staff in advance of submitting a formal PUF application, particularly if you are submitting an Intermacs application.
If you have questions about the PUF Program, contact Robert H. Habib, Research Center Director, at Robert Habib.
Watch the video below, in which Drs. David M. Shahian and Felix G. Fernandez talk with STS Research Center Director Robert H. Habib about how the PUF Program differs from the STS Access & Publications Program, as well as explain the proposal submission process.
