The dangerous precedent of censoring scientific dissemination.

The American Transplant Congress (ATC) is the largest national transplant meeting in the United States jointly sponsored by the American Society of Transplantation and the American Society of Transplant Surgeons. The 2024 ATC was held in Philadelphia, Pennsylvania during which a number of peer-reviewed scientific abstracts were censored from the program by the Health Resources and Services Administration. These abstract presentations were redacted from the program for perceived conflict with current government policy effectively restricting dissemination of highly rated findings and discussion in a scientific forum. In this viewpoint, we describe the content of the abstracts that were withdrawn from the annual ATC meeting and the implications of this censorship by the Health Resources and Services Administration. We further consider the ramifications of this action for the prospective evaluation of government policy and the relationship of the contract agency with the transplant community in the context of ongoing discussions of modernizing the transplant system which has previously been critiqued for lack of transparency.
