Estimated Median Waiting Time for Organ Procurement and Transplantation Network Human Immunodeficiency Virus Organ Policy Equity Act Variance Kidney Candidates: A Propensity Score Matched Analysis.

Background: Prior to the 2013 HIV Organ Policy Equity (HOPE) Act, which enabled research on the transplantation of solid organs from donors with human immunodeficiency virus (HIV) to candidates living with HIV, it was prohibited for HIV+ individuals to donate organs in the United States. In 2015, alongside the release of HOPE Act research criteria, the Organ Procurement and Transplantation Network (OPTN) made organ allocation policy and system changes to allow HIV+ to HIV+ transplantation.

Methods: The OPTN database was queried for all adult kidney registrations ever waiting from November 23, 2015, to December 31, 2022; the cohort was split into a HOPE cohort (ever willing to accept an HIV+ kidney) and a non-HOPE cohort (all remaining).

Individual-level social determinants of health and disparities in access to kidney transplant and waitlist mortality.

Background: Comprehensive, individual-level social determinants of health (SDOH) are not collected in national transplant registries, limiting research aimed at understanding the relationship between SDOH and waitlist outcomes among kidney transplant candidates.

Methods: We merged Organ Procurement and Transplantation Network data with individual-level SDOH data from LexisNexis, a commercial data vendor, and conducted a competing risk analysis to determine the association between individual-level SDOH and the cumulative incidence of living donor kidney transplant (LDKT), deceased donor kidney transplant (DDKT), and waitlist mortality. We included adult kidney transplant candidates placed on the waiting list in 2020, followed through December 2023.

Augmenting the Unites States transplant registry with external mortality data: A moving target ripe for further improvement.

The Organ Procurement and Transplantation Network conducts a robust death verification process when augmenting the United States transplant registry with external sources of data. Process enhancements added over 35,000 externally verified deaths across waitlist candidates and transplant recipients for all organs beginning in April 2022. Ninety-four percent of added posttransplant deaths occurred beyond 5 years posttransplant, and over 74% occurred beyond 10 years.

Kidney accelerated placement project: Outcomes and lessons learned.

Opportunities continue to be lost with a high rate of kidneys recovered for transplant but not utilized, particularly those considered less than ideal quality. The Organ Procurement and Transplantation Network (OPTN) Organ Center is tasked with allocating arguably the most difficult-to-place kidneys, and we hypothesized an accelerated placement pathway would increase utilization of kidneys placed by the Organ Center. The Kidney Accelerated Placement (KAP) project, implemented by the Organ Center from July 18, 2019 to July 15, 2020, aimed to offer kidneys with a high kidney donor profile index to programs that had a history of accepting such organs.

New-onset Diabetes Mellitus After Adult Heart Transplantation and the Risk of Renal Dysfunction or Mortality.

Background: Diabetes mellitus (DM) may occur either pre-heart transplantation (HT) or as new-onset DM post-HT. We sought to define the contemporary incidence of post-HT DM, evaluate risk factors for post-HT DM, and assess the impact of post-HT DM on major outcomes.

Methods: The cohort included International Society for Heart and Lung Transplantation Thoracic Organ Transplant Registry adult primary HT-alone recipients, transplanted January 1995-June 2017, who survived to 1 y post-HT.

Increase in Alcoholic Hepatitis as an Etiology for Liver Transplantation in the United States: A 2004-2018 Analysis.

Background: Changing opinions on the alcohol abstinence requirement have led to increased liver transplantation (LT) for alcoholic hepatitis (AH). We aimed to determine the trend in LT for AH in the United States and overall and graft survival rates.

Methods: Adult liver-alone and liver-kidney registrations added to the Organ Procurement and Transplantation Network waiting list between 2004 and 2018 were divided into 3 periods (2004-2009, 2010-2013, 2014-2018).

Informed Clustering of Donation Service Areas for Improved Benchmarking.

The donation community continuously strives to collaborate and share effective practices to further the mission of saving and healing lives. Donation service areas in which the Organ Procurement Organizations (OPOs) work are multifaceted in their demographics, inciting the Organ Procurement and Transplantation Network to consider a more holistic and objective measure of similarity rather than the size of population alone or locational proximity alone. This would allow OPOs, as a part of their quality improvement efforts, to learn from and mentor other organizations that are dealing with similar challenges.
