Researchers

The SRTR works to support and collaborate with the community of researchers interested in transplantation issues. Typically, the research audience of the SRTR includes public health services researchers, biostatisticians, and transplant clinicians.

The following SRTR resources may be of value to transplant researchers:

  • Articles on research methods describing the statistical and data methodologies used in various SRTR reports.
  • Data release guidelines that review how to request information and data from the SRTR. SRTR Standard Analysis Files (SSAFs) are available to researchers wishing to perform their own data analyses. These files, which are accompanied by an electronic data dictionary and a limited amount of technical support from SRTR staff, include data elements collected by the OPTN and supplemented with other sources. Calculated analytical variables are also available.
  • Simulation Allocation Models (SAMs) contain information and documentation about a family of computer programs developed by the SRTR to simulate organ allocation under varying circumstances and forecast outcomes for candidates on the waiting list and following transplant. The SAM family consists of the Liver Simulated Allocation Model (LSAM), the Thoracic Simulated Allocation Model (TSAM), and the Kidney-Pancreas Simulated Allocation Model (KPSAM).
  • The SRTR Publications Database provides slides and abstracts that can be downloaded for use, as well as information about how to obtain other related material.
  • Annual Reports provide a yearly look at important issues and outcomes within the national transplant community. These reports offer more than 250 tables of comprehensive transplant data, showing both recent activity and 10-year trends. Analyses of outcome predictors are also included.
  • Annual Report chapters, also published in the American Journal of Transplantation as the SRTR Report on the State of Transplantation, are prepared by transplant experts from across the country. These articles focus on current issues for specific organs. Other chapters discuss issues important across all organs, such as immunosuppression, transplant tourism, and performance measures.
  • The SRTR has created a limited dataset for instructional use to help university professors and other higher education instructors develop data management and analytic skills in their students. These data should not be used to conduct research or to address clinical or scientific questions. For information on how to obtain actual clinical data from the SRTR, go here.
