Organ Transplantation
About SRTR
The Scientific Registry of Transplant Recipients (SRTR) was established by the National Organ Transplant Act (NOTA, 1984 Pub.L. 98–507) and supports ongoing evaluation of the status of solid organ transplantation in the United States. It is administered by the Chronic Disease Research Group (CDRG) through contract by the Health Resources and Services Administration (HRSA).
SRTR responsibilities include designing and carrying out rigorous scientific analyses of data and disseminating information to the transplant community, including transplant programs, organ procurement organizations, policy makers, transplant professionals, transplant recipients, organ donors and donor families, and the general public. In addition, SRTR helps facilitate research in the area of solid organ transplantation by providing access to data for qualified researchers interested in studying various aspects of solid organ transplantation.
The U.S. organ transplantation system employs evidence-based allocation policy development through collaborative efforts between the transplant community, SRTR, and the Organ Procurement and Transplantation Network (OPTN). While policy making is OPTN’s responsibility, SRTR plays a critical role in policy development through ongoing data analyses designed to provide policy makers with the information necessary to make informed decisions.
The entire system benefits from transparency, consensus, and cooperation among all interested parties including the public, SRTR, OPTN, HRSA, and the Advisory Committee on Organ Transplantation (ACOT).
CDRG investigators and staff together with SRTR senior staff from around the U.S. have substantial knowledge and experience working on large epidemiologic projects such as this registry. Past projects have provided experience in health outcomes and transplantation research, leading to publications in peer-reviewed journals covering such topics as patient mortality, morbidity, and quality of life; organ allocation, organ transplant waiting lists; organ procurement; and posttransplant outcomes.
More information about SRTR, including ways to contact and obtain data, can be found on the SRTR website. SRTR also publishes information and interactive content (infographics) on social media via their LinkedIn, Twitter, and YouTube pages. Additionally, SRTR distributes its newsletter, The Data Review. The purpose of this newsletter is to inform transplant community members of what SRTR has been working on, and gives subscribers an opportunity to forward and share the content with fellow transplant community members. You can sign up for the newsletter at the bottom of the SRTR website homepage. SRTR also conducts webinars for the transplant community, making the webinars available live (with audience registration) and later available for viewing on its YouTube page. If you have any questions, you can email SRTR at srtr@srtr.org.
