Artificial intelligence (AI) is rapidly transforming healthcare, and the field of kidney transplantation (KT) is no exception. While much of the AI-related work has focused on deceased donor KT, there is a growing body of research applying AI tools to living kidney donation (LKD). This review explores AI's current and potential roles in LKD, focusing on predictive and social applications of AI in LKD. Additionally, we discuss the challenges and limitations of implementing AI in clinical settings and highlight emerging research trends. This review consolidates existing research and provides a foundation for both transplant professionals and data scientists seeking to integrate AI responsibly into living donor programs.

INTRODUCTION/BACKGROUND:The United States Organ Procurement and Transplantation Network mandates collection of 6-month, 1-year, and 2-year post-donation follow-up data on living kidney donors (LKDs), but many centers struggle to meet these requirements. This study investigated whether providing a financial incentive (mailed gift card) could increase patient compliance with LKD follow-up. METHODS:A parallel, non-blinded, 1:1 superiority randomized control trial of LKDs was conducted at two centers from March 2017 to February 2021. The control arm received standard of care (SOC): instructions to complete the mandated LKD follow-up consisting of a health questionnaire and laboratory measurements at 6 months, 1 year, and 2 years post-donation. The intervention arm received SOC and was mailed a $25 gift card for each timely completed follow-up. Compliance rates were compared at each timepoint using Poisson regression. RESULTS:at 2 years). Similarly, no differences were observed in compliance with clinical follow-up, laboratory follow-up, or individual questions or lab values. CONCLUSION/CONCLUSIONS:Mailed gift cards did not improve patient compliance with LKD follow-up requirements; such interventions may be counterproductive among LKDs. Further research is needed to investigate and address barriers to completing LKD follow-up. TRIAL REGISTRATION/BACKGROUND:ClinicalTrials.gov identifier: NCT03090646.

BACKGROUND:The HIV (human immunodeficiency virus) Organ Policy Equity (HOPE) Act legalized transplantation from both living and deceased donors with HIV to recipients with HIV (HIV D+/R+). Since its enactment, only a few living organ donations from people with HIV (PWH) have occurred compared to more deceased donations. The study aims to understand the perspectives of infectious disease providers and their awareness of HIV-positive donors with a reactive status (HIV D+/R+) to inform the practice, as kidney and liver transplants from these donors can now be conducted outside of research protocols. METHODS:Semi-structured interviews were conducted with infectious disease providers (n = 18) from October 2023 to March 2024 to assess their perceptions and knowledge of HIV D+/R+ living organ donation. Inductive thematic analysis was conducted to identify major themes. RESULTS:Most providers had a positive view of HIV D+/R+ living donation, noting its potential to expand the donor pool, reduce wait times, and reduce stigma surrounding organ transplantation for PWH. However, they expressed concerns about the long-term outcomes of donors and emphasized the importance of thorough evaluations, including assessments of the disease stage and comorbidities. Additionally, providers mentioned that they had limited knowledge of the HIV D+/R+ donation process and highlighted the need for educational resources and establishing formal relationships with transplant programs. CONCLUSIONS:The study findings highlight the need for evidence-based information resources for healthcare providers on HIV D+/R+ living donations.

Community input enhances the impact of research. Yet, there are challenges when eliciting community perspectives in nephrology/transplant research: recruitment of patients across a wide spectrum of familiarity with kidney disease; a lack of trust from marginalized patients because of health care barriers, institutionalized structural racism, and historical harm; and retention of members facing high burden of care. To address these challenges, we drafted a mission and formed a community advisory board to provide input on nephrology/transplant research. We worked with kidney disease community organizations that prioritize diversity and equity to recruit members with chronic kidney disease, end-stage kidney disease, or a kidney transplant, as well as nephrology/transplant caregivers and kidney donors. We formed a diverse group of 9 members and received feedback on 5 research proposals over 4 quarterly meetings, bridging a communication gap between community perspectives and researchers. The collaborative environment stimulated feedback that improved our nephrology/transplant research to reflect the perspectives of those most affected by research findings. Eight members have remained active for more than 1 year. In this collaborative paper, we describe our process of forming a nephrology/transplant community advisory board, and participants highlight the benefits of sharing their lived experiences to improve and amplify the impact of nephrology/transplant research.

BACKGROUND:Transplant waitlist registrants in the United States may be delisted because of receipt of a transplant abroad. Although not universally unethical, "travel for transplantation" poses risks to posttransplant care. To better understand this phenomenon, this study identifies temporal trends, geographic patterns, and demographic factors associated with cross-border transplantation. METHODS:Using Scientific Registry of Transplant Recipients data, we identified 818 US waitlist candidates who were removed because of transplantation abroad between 2010 and 2023. We described recipient characteristics overall, by organ, and by top transplant destinations. We used a Cox regression framework to identify characteristics associated with waitlist removal due to transplantation abroad. RESULTS:Transplants abroad averaged 58.4 per year. Incidence peaked at 80 transplants in 2017, with an upward trend after 2021. Kidney transplants made up 92.1% of cases. The most common destinations were the Philippines (19.8%), India (16.5%), Mexico (9.4%), China (8.4%), and Iran (4.4%). India and Mexico experienced the smallest drop-off during the height of the COVID-19 pandemic 2020-2021. Most recipients were US citizens (65.0%) or residents (23.5%). Female (adjusted hazard ratio [aHR], 0.520.610.71; P < 0.001) and Black candidates (aHR, 0.120.180.26; P < 0.001) were less likely to travel abroad compared with Asian candidates (aHR, 5.927.108.52; P < 0.001). Nonresidents (aHR, 6.708.6911.26; P < 0.001) and, among registrations in 2012 or later, nonresidents who traveled to the United States for transplantation (aHR, 27.2738.9155.50; P < 0.001) had a greater chance of undergoing transplantation abroad. CONCLUSIONS:Understanding patterns of international travel for transplantation is key not only for preventing resource drains from destination countries but also for providing adequate posttransplant care for recipients.

Research shows that donor families report feeling abandoned, lacking social support, and receiving insufficient aftercare services. To meet the needs of these families, Taylor's Gift Foundation developed a free, virtual grief support program that pairs participating donor family members with Caring Guides trained in assertive community engagement and offers peer-facilitated support groups. Project Aim: The aim was to assess participant experiences with Taylor's Gift Foundation grief support program to understand its impact on grief symptoms, donor family access to grief support, and perceived social support. Design: Researchers conducted a qualitative evaluation using semi-structured interviews with 21 program participants. Results were analyzed using rapid qualitative analysis and descriptive statistics. Results: Eighteen (86%) participants worked with Caring Guides, 12 (57%) attended an average of 7 support groups, and 8 (39%) worked with Caring Guides and attended support groups. Eleven (52%) program participants reported difficulties accessing mental health services. Most program participants (86%) reported a decrease in grief intensity since enrolling in the program. Conclusion: Effective aftercare services were critical in helping donor families cope with, and adapt to, their loss. The Taylor's Gift Foundation grief support program helped donor family members access otherwise inaccessible grief support services and provided a valuable means of social support.

INTRODUCTION/BACKGROUND:Dialysis social workers (DSWs) educate and advocate for end-stage kidney disease (ESKD) patients during the kidney transplantation (KT) process. However, little is known about the barriers DSWs face as they help patients get waitlisted and how to best support their efforts. We interviewed DSWs across New York (NY) State to examine their experiences, supports, and challenges in helping dialysis patients progress through KT education, referral, and evaluation. METHODS:We conducted semi-structured interviews with DSWs in NY State who had participated or expressed interest in a program designed to educate DSWs about KT and used rapid qualitative analysis to identify themes. FINDINGS/RESULTS:We interviewed 17 DSWs. Seven themes emerged: (1) DSWs report involvement in KT interest assessment, education, referral, and evaluation support, (2) DSWs report varying nephrologist support in helping patients progress to KT, (3) DSWs perceive social support and adherence as key factors in KT centers' eligibility determinations, (4) DSWs have knowledge gaps around living donation and appreciate learning about KT from transplant centers and non-profit organizations, (5) Patients express KT concerns and DSWs counsel them about these concerns, (6) DSWs report solutions to help patients complete KT evaluation appointments, and (7) DSWs report communication deficiencies between dialysis centers and transplant centers, and patients. CONCLUSIONS:Education for DSWs, support from nephrologists, and resources to help patients complete KT evaluation steps facilitated DSW engagement throughout the pre-transplant process, underscoring the need for multi-level, cross-disciplinary programs to support these efforts.
