Data Request

If you are at an OPTN Member transplant center, OPO or histocompatibility lab, and have access to UNetSM, please log in to Secure Enterprise and submit your data request using the UNOS Service Portal.

All fields below are required.










STAR (Standard Transplant Analysis and Research) files are DVDs with datasets that contain de-identified patient-level information for transplant recipients and waiting list candidates back to 10/1/1987. Use of a STAR file requires knowledge of database software capable of manipulating files with thousands of records and hundreds of variables, such as SAS or SPSS. Please note that the size of the STAR files precludes the use of software such as Microsoft Excel and Access.

Be as specific as possible about your request. Elaborate on the organ, time period, donor types and transplant types for which you are requesting data. UNOS members looking for center-specific data should indicate that information as well.
