Determinants of kidney transplant candidates' decision to accept organ donor intervention transplants and participate in post-transplant research: A conjoint analysis.

Deceased organ donor intervention research aims to increase organ quality and quantity for transplantation. We assessed the proportion of kidney transplant candidates who would accept "intervention organs," participate in organ intervention research, and factors influencing acceptance. Kidney transplant candidates were presented 12 hypothetical scenarios, which varied three attributes, donor age, predicted waiting time to receive another organ offer, and research risk to the organ. Candidates were also randomly assigned to one of two conditions varying recipient risk. For each scenario, candidates agreed to accept the intervention organ or remain waitlisted. We fit a multivariable logit model to determine the association between scenario attributes and the acceptance decision. Of 249 participants, most (96%) accepted intervention organs under some or all conditions. Factors independently associated with candidates' greater likelihood of accepting an intervention organ included: low risk to the kidney from the intervention (OR 20.53 [95% Confidence Interval (CI), 13.91-30.29]); younger donor age (OR 3.72 [95% CI, 2.83-4.89]), longer time until the next organ offer (OR 3.48 [95% CI, 2.65-4.57]), and greater trust in their transplant physician (OR 1.03 [95% CI, 1.00-1.06]). Candidates with a lower likelihood of acceptance had been waitlisted longer (OR 0.97 per month [95% CI, 0.96-0.99]) and were Black (OR 0.21 [95% CI, 0.08-0.55]). Most candidates would accept an intervention organ, which should encourage transplant leaders to conduct deceased donor organ intervention trials.

A Study of Concerns of Families of Potential Donation After Circulatory Death Donors and Recommendations for Raising Donation Rates.

CONTEXT: The request process for donation after circulatory death (DCD) and family concerns about DCD differ in significant ways from the process for, and family concerns about, donation after brain death (DBD). In addition, donation rates for DCDs are typically lower than for DBDs. Although there has been a great deal of research on how the concerns of DBD families impact donation, limited research exists on family concerns and decision-making in the DCD request process. OBJECTIVE: To determine the concerns of families approached for DCD and explore how those might be addressed to increase DCD donation rates. DESIGN, SETTING, AND PARTICIPANTS: Written request response forms were completed by organ procurement and family services coordinators from 4 organ procurement organizations in 4 different states. They were filled out as soon as possible after speaking with families about DCD. MAIN OUTCOME MEASURES: Responses were marked on a 12-item instrument, and anecdotal observations and detailed comments about family concerns, donor registration status, and decisions made were noted. RESULTS: Family concerns that block DCDs differ in many ways from those that block DBDs. These concerns arise from stresses peculiar to the DCD situation and must be addressed for these types of donations to increase. PURPOSE OF THE STUDY: The purposes of the study are to identify family concerns about donating organs that are specific to DCD and that may differ from DBD and to distinguish how those concerns might be addressed in ways that increase the likelihood of donation.

Solid organ donation after death in the United States: Data-driven messaging to encourage potential donors.

US deceased donor solid organ transplantation (dd-SOT) depends upon an individual's/family's altruistic willingness to donate organs after death; however, there is a shortage of deceased organ donors in the United States. Informing individuals of their own lifetime risk of needing dd-SOT could reframe the decision-making around organ donation after death. Using United Network for Organ Sharing (UNOS) data (2007-2016), this cross-sectional study identified (1) deceased organ donors, (2) individuals waitlisted for dd-SOT (liver, kidney, pancreas, heart, lung, intestine), and (3) dd-SOT recipients. Using US population projections, life tables, and mortality estimates, we quantified probabilities (Pr) of (1) becoming deceased organ donors, (2) needing dd-SOT, and (3) receiving dd-SOT. Lifetime Pr (per 100 000 US population) for males and females of becoming deceased organ donors were 212 and 146, respectively, and of needing dd-SOT were 1323 and 803, respectively. Lifetime Pr of receiving dd-SOT was 50% for males, 48% for females. Over a lifetime, males were 6.2 and females 5.5 times more likely to need dd-SOT than to become deceased organ donors. Organ donation is traditionally contextualized in terms of charity toward others. Our analyses yield a new tool, in the form of quantifying an individual's own likelihood of needing dd-SOT, which may assist with reframing motivations toward deceased donor organ donation.

Transplant candidates' perceptions of informed consent for accepting deceased donor organs subjected to intervention research and for participating in posttransplant research.

Deceased donor organ intervention research holds promise for increasing the quantity and quality of organs for transplantation by minimizing organ injury and optimizing function. Such research will not progress until ethical, regulatory, and legal issues are resolved regarding whether and how to obtain informed consent from transplant candidates offered intervention organs given time constraints intrinsic to distribution. This multi-center, mixed-methods study involved semi-structured interviews using open- and closed-ended questions to assess waitlisted candidates' preferences for informed consent processes if offered an organ after undergoing intervention. Data were analyzed thematically. Sixty-one candidates participated (47% participation rate). Most were male (57%), white (61%), with a mean age of 56 years. Most candidates (79%) desired being informed that the organ offered was an intervention organ before accepting it, and were likely to accept an intervention organ if organ quality was good (defined as donor age 30) (81%), but fewer candidates would accept an intervention organ if quality was moderate (ie, donor age 50) (26%). Most perceived informed consent important for decision-making, while others considered it unnecessary given medical necessity to accept an organ and trust in their physician. Our findings suggest that most candidates desire an informed consent process before accepting an intervention organ and posttransplant data collection.
