The SRTR Standard Analysis File (SAF) includes many of the data elements collected
by OPTN on all solid organ transplant candidates, donors, and recipients in the
United States from 1989 to the present. These data are supplemented by data from
the Social Security Death Master File (SSDMF). The SRTR SAF provides data on solid
organ transplantation, including heart, lung, kidney, pancreas, liver, and intestine
transplants and combinations thereof.
The SAF is released quarterly (March, June,
September, and December of each year) and is available only in SAS.
This Data Dictionary
is intended as a guide to the contents of the SAF. The SAF includes encrypted patient
identifiers, encrypted transplant center codes, and encrypted organ procurement
organization codes. These codes allow for the various files to be linked. In general,
the SAF does not include geographic data or text fields. Some data elements that
are not part of the standard files, such as OPTN region, may be included upon request.
These supplementary files may incur additional cost and require approval.
