National Analysis of Recent Trends in Organ Donation and Transplantation in the United States: Toward Optimizing Care Delivery and Patient Outcomes

Abstract

Introduction: In 2021, over 100 000 people were awaiting solid organ transplantation, yet only 44 634 transplants were performed. The aim of this study is to evaluate trends in donor availability, waitlist additions, and transplants performed in the United States from 2001 to 2021.

Methods: This was a retrospective analysis to evaluate trends in donor availability, waitlist additions, and solid organ transplants for the 4 most common organs requiring transplants (kidney, liver, heart, and lung) between 2001 and 2021 according to OPTN data.

Results: Between 2001 and 2021, the overall number of transplants performed, donors available, and waitlist additions increased by 71%, 61%, and 54%, respectively. The number of kidney transplant waitlist additions significantly increased compared to other organs (P < .001). For each kidney transplant performed, there was a 2.25 increase in waitlist additions throughout the study period (P < .001). For each liver and heart transplant performed, there was a .92 and .80 increase in waitlist additions, respectively (P < .001). Lung transplants increased the most by 138% and there was an increase in waitlist additions for every transplant by 1.0 (P < .001).

Conclusion: There was an absolute increase in the annual number of transplants, donor recruitment, and patients added to the waitlist between 2001 and 2021. Kidney transplant waitlist additions are increasing at a rate outpacing the rates of donor recruitment and transplantation.
