ABSTRACT
Introduction: Improving public awareness about the opportunity to become a vascularized composite allograft (VCA) donor is crucial to increasing access to organs. Prior research identified a need for comprehensive and comprehensible public education materials. A 2-round Delphi panel was conducted to garner US expert consensus on the topics and language to include in public education materials via an organ procurement organization-hosted website. Methods: The round 1 survey assessed the importance of educational topics and statements (n = 19) using 5-point Likert scales. The round 2 survey asked experts to rate new and repeated educational topics (n = 27). Open-ended comment boxes elicited experts' feedback and language revisions for educational statements. Responses were analyzed using descriptive statistics and rapid qualitative analysis. Findings: Eighteen experts responded to the round 1 survey and 15 to round 2. After round 2, 20 topics had mean (M) importance greater than neutral (M > 3.00) and were retained in the educational materials. The 5 most important topics by mean Likert ratings were: consent process for donation (M = 4.73), potential recipients (M = 4.73), most common vascularized composite organs transplanted (M = 4.47), purpose (M = 4.47), and definition (M = 4.47). Seven themes emerged from experts' open-ended comments about the importance and language of educational statements. Conclusions: Delphi panel findings identified expert-endorsed topics and educational statements for public education about vascularized composite organ donation via an educational website. Future research should assess the website's impact on public knowledge of VCA donation.
ABSTRACT
Background: Organ transplantation from donors with hepatitis C viremia (HCV) to recipients without HCV (HCV D+/R-) has excellent medical outcomes. Less is known about the psychosocial impact and experiences of HCV D+/R- recipients, particularly outside of clinical trials. Methods: We conducted in-depth, semistructured interviews with 24 HCV D+/R- recipients (kidney, n = 8; lung, n = 7; liver, n = 5; heart, n = 3; simultaneous heart and kidney, n = 1) who received transplants outside of clinical trials and were treated for HCV after transplant to assess their experiences and perspectives. We used thematic analysis to analyze the interviews. Results: Interviewees' reasons for accepting an HCV D + organ were based on perceived benefits and confidence in the effectiveness of HCV treatment. The majority (62%) received HCV treatment within 1 month after transplant (range, 1 day-2 months). Most interviewees reported positive transplant outcomes, including reduced wait times and improved survival, health, physical activity, and quality of life. Overall, themes and experiences did not differ significantly between different organ transplant types. Generally, interviewees did not perceive stigma from those aware of the HCV D+ transplant; yet, disclosure was selective and a few recipients reported concerns from family members about posttransplant HCV transmission risk. Other common concerns included treatment costs and delays, which were not always anticipated by recipients. Conclusions: Our findings suggest that HCV D+/R- kidney, liver, and heart and lung transplant recipients outside of clinical trials had overall positive experiences. However, HCV transmission risk, treatments costs, and treatment delays were a source of concern that might be mitigated with targeted pretransplant education.
ABSTRACT
Rationale & Objective: Understanding national attitudes about living kidney donation will enable us to identify and address existing disincentives to living kidney donation. We performed a national survey to describe living kidney donation perceptions, perceived factors that affect the willingness to donate, and analyzed differences by demographic subgroups. Study Design: The survey items captured living kidney donation awareness, living kidney donation knowledge, willingness to donate, and barriers and facilitators to living kidney donation. Setting & Population: We surveyed 802 US adults (aged 25-65 years) in June 2021, randomly selected from an online platform with diverse representation. Analytical Approach: We developed summed, scaled indices to assess the association between the living kidney donation knowledge (9 items) and the willingness to donate (8 items) to self-reported demographic characteristics and other variables of interest using analysis of variance. All other associations for categorical questions were calculated using Pearson's χ2 and Fisher exact tests. We inductively evaluated free-text responses to identify additional barriers and facilitators to living kidney donation. Results: Most (86.6%) of the respondents reported that they might or would definitely consider donating a kidney while they were still living. Barriers to living kidney donation included concerns about the risk of the surgery, paying for medical expenses, and potential health effects. Facilitators to living kidney donation included having information on the donation surgery's safety, knowing that the donor would not have to pay for medical expenses related to the donation, and hearing living kidney donation success stories. Awareness of the ability to participate in kidney-paired donation was associated with a higher willingness to donate. Limitations: Potential for selection bias resulting from the use of survey panels and varied incentive amounts, and measurement error related to respondents' attention level. Conclusions: Most people would consider becoming a living kidney donor. Increased rates of living kidney donation may be possible with investment in culturally competent educational interventions that address risks associated with donating, policies that reduce financial disincentives, and communication campaigns that raise awareness of kidney-paired donation and living kidney donation.
Understanding what the general public thinks about living kidney donation will help to develop better education and increase the number of living kidney donors. We surveyed the public to find out: (1) how aware they are about the opportunity to donate a kidney while alive; (2) how much they know about living kidney donation; (3) whether they would be willing to donate; and (4) what would affect their willingness to donate. We found that teaching people about the risks of donating, decreasing costs related to donation, and raising awareness about it could increase the number of people willing to donate.
ABSTRACT
Research involving recently deceased humans that are physiologically maintained following declaration of death by neurologic criteria-or 'research involving the recently deceased'-can fill a translational research gap while reducing harm to animals and living human subjects. It also creates new challenges for honouring the donor's legacy, respecting the rights of donor loved ones, resource allocation and public health. As this research model gains traction, new empirical ethics questions must be answered to preserve public trust in all forms of tissue donation and in the practice of medicine while respecting the legacy of the deceased and the rights of donor loved ones. This article suggests several topics for immediate investigation to understand the attitudes and experiences of researchers, clinical collaborators, donor loved ones and the public to ensure research involving the recently deceased advances ethically.
ABSTRACT
BACKGROUND: The use of large-scale data and artificial intelligence (AI) to support complex transplantation decisions is in its infancy. Transplant candidate decision-making, which relies heavily on subjective assessment (ie, high variability), provides a ripe opportunity for AI-based clinical decision support (CDS). However, AI-CDS for transplant applications must consider important concerns regarding fairness (ie, health equity). The objective of this study was to use human-centered design methods to elicit providers' perceptions of AI-CDS for liver transplant listing decisions. METHODS: In this multicenter qualitative study conducted from December 2020 to July 2021, we performed semistructured interviews with 53 multidisciplinary liver transplant providers from 2 transplant centers. We used inductive coding and constant comparison analysis of interview data. RESULTS: Analysis yielded 6 themes important for the design of fair AI-CDS for liver transplant listing decisions: (1) transparency in the creators behind the AI-CDS and their motivations; (2) understanding how the AI-CDS uses data to support recommendations (ie, interpretability); (3) acknowledgment that AI-CDS could mitigate emotions and biases; (4) AI-CDS as a member of the transplant team, not a replacement; (5) identifying patient resource needs; and (6) including the patient's role in the AI-CDS. CONCLUSIONS: Overall, providers interviewed were cautiously optimistic about the potential for AI-CDS to improve clinical and equitable outcomes for patients. These findings can guide multidisciplinary developers in the design and implementation of AI-CDS that deliberately considers health equity.

Objective: Upper extremity vascularized composite allotransplantation is an innovative treatment option for people with upper extremity amputations. Limited patient-relevant long-term outcomes data about transplant success may impede patients' informed treatment decision-making. We assessed perceptions of what constitutes upper extremity vascularized composite allotransplantation success among individuals with upper extremity amputations. Methods: This multisite study entailed interviews and focus groups with individuals with upper extremity amputations and upper extremity vascularized composite allotransplantation candidates, participants, and recipients. We examined perceptions of transplant success and preferences for five upper extremity vascularized composite allotransplantation outcomes. Qualitative data were analyzed using thematic analysis; and quantitative data were analyzed using descriptive statistics. Results: In all, 50 individuals participated in interviews (61.7% participation rate), and 37 participated in nine focus groups (75.5% participation rate). Most were White (72%, 73%), had a mean age of 45 and 48 years, and had a unilateral amputation (84%, 59%), respectively. Participants conceptualized upper extremity vascularized composite allotransplantation success as transplant outcomes: (1) restoring function and sensation to enable new activities; (2) accepting the transplanted limb into one's identity and appearance; (3) not having transplant rejection; (4) attaining greater quality of life compared to prosthetics; and (5) ensuring benefits outweigh risks. Participants rated their most important upper extremity vascularized composite allotransplantation outcomes as follows: not having transplant rejection, not developing health complications, grasping objects, feeling touch and temperature, and accepting the upper extremity vascularized composite allotransplantation into your identity. Conclusion: Individuals with upper extremity amputations maintain several conceptions of vascularized composite allotransplantation success, spanning functional, psychosocial, clinical, and quality of life outcomes. Providers should address patients' conceptions of success to improve informed consent discussions and outcomes reporting for upper extremity vascularized composite allotransplantation.
ABSTRACT
Background: Upper extremity vascularized composite allotransplantation is a life-enhancing reconstructive treatment option that aims to improve recipients' quality of life and maximize function. This study assessed upper extremity vascularized composite allotransplantation patient selection criteria perceptions among individuals with upper extremity limb loss. The perceptions of individuals with upper extremity limb loss on patient selection criteria may enable vascularized composite allotransplantation centers to improve criteria to avoid mismatched expectations about the posttransplant vascularized composite allotransplantation experience and outcomes. Realistic patient expectations may increase patient adherence, improve outcomes, and reduce vascularized composite allotransplantation graft loss. Methods: We conducted in-depth interviews with civilian and military service members with upper extremity limb loss and upper extremity vascularized composite allotransplantation candidates, participants, and recipients from three US institutions. Interviews assessed perceptions of patient selection criteria for suitability as a candidate for upper extremity vascularized composite allotransplantation. Thematic analysis was used to analyze qualitative data. Results: A total of 50 individuals participated (66% participation rate). Most participants were male (78%), White (72%), with a unilateral limb loss (84%), and a mean age of 45 years. Six themes emerged regarding upper extremity vascularized composite allotransplantation patient selection criteria, including support for candidates who: (1) are of younger age, (2) are in good physical health, (3) have mental stability, (4) are willing to "put in the work," (5) have specific amputation characteristics, and (6) have sufficient social support. Patients had preferences about selecting candidates with unilateral versus bilateral limb loss. Conclusions: Our findings suggest that numerous factors, including medical, social, and psychological characteristics, inform patients' perceptions of patient selection criteria for upper extremity vascularized composite allotransplantation. Patient perceptions of patient selection criteria should inform the development of validated screening measures that optimize patient outcomes.
ABSTRACT
BACKGROUND: Medication non-adherence contributes to post-transplant graft rejection and failure; however, limited knowledge about the reasons for non-adherence hinders the development of interventions to improve adherence. We conducted focus groups with solid organ transplant recipients regarding overlooked challenges in the process of transplant medication self-management and examined their adherence strategies and perceptions towards the post-transplant medication regimen. METHODS: We conducted four focus groups with n = 31 total adult transplant recipients. Participants had received kidney, liver, or combined liver/kidney transplant at Johns Hopkins Hospital between 2014 and 2019. Focus groups were audio-recorded and transcribed. Transcripts were analyzed inductively, using the constant comparative method. RESULTS: Responses generally fell into two major categories: (1) barriers to adherence and (2) "adherence landscape". We define the former as factors directly labeled as barriers to adherence by participants and the latter as factors that heavily influence the post-transplant medication self-management process. CONCLUSIONS: We propose a shift in the way healthcare providers and researchers, address the question of medication non-adherence. Rather than asking why patients are non-adherent, we suggest that constructing and understanding patients' "adherence landscape" will provide an optimal way to align the goals of patients and providers and boost health outcomes.

BACKGROUND: The Scientific Registry of Transplant Recipients (SRTR) Living Donor Collective (LDC), the first effort to create a lifetime registry for living donor candidates in the United States, requires transplant programs to register donor candidates while the SRTR conducts follow-up. METHODS: To better understand facilitators and barriers to program participation, we conducted a brief electronic survey of U.S. transplant program staff from October 26, 2021 to December 17, 2021. RESULTS: We received 132 responses, with at least one response from 87 living donor programs (46 kidney programs, 33 kidney and liver programs, and eight liver programs alone). We found 86% of program representatives strongly agreed or agreed that funding adequate to cover the cost of data collection would facilitate LDC participation, 92% agreed or strongly agreed with importance of electronic data submission options, and 74% reported that elimination of requirements to submit duplicative pre-operative information to the Organ Procurement and Transplantation Network (OPTN) would be helpful. Other potentially enabling factors include reduction in duration of OPTN postdonation follow-up requirements, ease-of-use, protection from data use for regulation, adequate data security, and equity in data access. CONCLUSION: This survey identifies potential targets to strengthen participation in the effort to create a national living donor registry in the United States. Collaboration and investment to overcome barriers to LDC participation among transplant programs are vital to generate long-term data on living donation for donor candidates, donors, and patients in need of transplant.

Following the outbreak of coronavirus disease 2019 (COVID-19) in the United States, the number of kidney waitlist additions and living-donor and deceased-donor kidney transplants (LDKT/DDKT) decreased substantially but began recovering within a few months. Since then, there have been several additional waves of infection, most notably, the Delta and Omicron surges beginning in August and December 2021, respectively. Methods: Using SRTR data, we compared observed waitlist registrations, waitlist mortality, waitlist removal due to deteriorating condition, LDKT, and DDKT over 5 distinct pandemic periods to expected events based on calculations from preepidemic data while accounting for seasonality and secular trends. Results: Although the number of daily waitlist additions has been increasing since May 2020, the size of the active waitlist has consistently declined, reaching a minimum of 52 556 on February 27, 2022. The recent Omicron surge knocked LDKT from 25% below baseline (incidence rate ratio [IRR] = 0.690.750.81) during the Delta wave to 38% below baseline (IRR = 0.580.620.67). DDKT, however, was less affected by the Omicron wave (IRR = 0.850.890.93 and 0.880.920.96 during the Delta and Omicron waves, respectively). Waitlist death decreased from 56% above baseline (IRR = 1.431.561.70) during Delta to 41% above baseline during Omicron, whereas waitlist removal due to deteriorating condition remained at baseline/expected levels during the Delta wave (IRR = 0.931.021.12) and the Omicron wave (IRR = 0.991.071.16). Conclusions: Despite exceptionally high COVID-19 incidence during the Omicron wave, the transplant system responded similarly to prior waves that imposed a lesser disease burden, demonstrating the transplant system's growing adaptations and resilience to this now endemic disease.
ABSTRACT
Purpose of Review: Living donor transplantation provides the best possible recipient outcomes in solid organ transplantation. Yet, identifying potential living donors can be a laborious and resource intensive task that heavily relies on the recipient's means and social network. Social media has evolved to become a key tool in helping to bring recipients and potential living donors together given its ease of utilization, widespread access, and improved recipient's comfort with public solicitation. However, in the USA, formal guidelines to direct the use of social media in this context are lacking. Recent Findings: To better inform the landscape and opportunities utilizing social media in living donation, the OPTN Living Donor Committee surveyed US transplant programs to explore programs' experiences and challenges when helping patients use social media to identify potential living donors (September 2019). A large majority of survey participants (N = 125/174, 72%) indicated that their program provided education to use social media to identify potential living donors and most programs tracking referral source confirmed an increase utilization over time. The use of social media was compounded with program and recipient's challenges including concerns about privacy, inadequate technology access, and knowledge gaps. In this review, we discuss the results of this national survey and recent literature, and provide suggestions to inform program practices and guidance provided to patients wishing to use social media to identify potential living donors. Summary: Transplant programs should become competent in the use of social media for potential living donor identification to empower patients interested in using this tool. Social media education should be provided to all patients regardless of voiced interest and, when appropriate, revisited at multiple time points. Programs should consider developing a "team of experts" that can provide focused education and support to patients embarking in social media living donor campaigns. Care should be taken to avoid exacerbating disparities in access to living donor transplantation. Effective and timely guidance to patients in the use of social media could enhance the identification of potential living donors.

ABSTRACT
Vascularized Composite Allotransplantation (VCA) involves transplantation of multiple tissues from a donor to a recipient (e.g., skin, muscle, bone). Little is known about the US public's perceptions of and attitudes toward VCA organ donation. This multi-site, cross-sectional, mixed methods study involved focus groups and surveys to assess members of the general public's attitudes about VCA, and willingness and barriers to donate VCA organs. Qualitative data were analyzed by thematic analysis; quantitative data were analyzed by descriptive statistics. In focus groups (n = 6, 42 participants), most participants were female (57%) and Black (62%) with mean age of 42.6 years. Three main themes emerged: 1) awareness and perceptions of VCA, 2) purpose of VCA donation, 3) and barriers to VCA donation. Participants had heard little about VCA and sought information about VCA donation. Participants perceived VCA as challenging their concepts of "normality" and voiced concerns that VCA would create "Frankenstein[s]." Barriers to VCA donation included disruptions to end-of-life arrangements and information gaps regarding the donation process. Participants reported moderate to high willingness to donate their hands (69%) and face (50%) Public education efforts should address the specific needs and concerns of the public to facilitate VCA donation and family authorization.

In the United States, a small proportion of potential deceased organ donor referrals lead to donation and recovery. Understanding variation in the processes involved between organ procurement organizations (OPOs) may help increase deceased donation and reduce the organ shortage. We studied 103 923 referrals from 10 OPOs from 2018 to 2019, of which 14.4% led to approach for authorization, 8.2% led to authorization, 5.1% led to organ recovery, and 4.8% led to transplantation. First-person authorization (FPA) was associated with threefold higher odds of donation (OR = 2.83 3.02 3.22 , p < .001). Female referrals had 11% lower odds of approach; when approached, Black and Hispanic referrals had 46% and 35% lower odds of authorization, respectively (all p < .001). There was substantial OPO-level variation in rates of approach, authorization, and organ recovery, which persisted after adjusting for age, sex, race, and FPA status. An OPO's relative rate of approach correlated strongly with its relative rate of donation among all referrals (ρ = 0.43). Correlation between an individual OPO's authorization rate among approached families, and overall rate of donation, was negative, suggesting that high authorization rates may be the result of selective approach practices. Therefore, approaching a higher proportion of families for authorization may lead to higher donation rates.
