PurposeOrgan transplantation systems benefit from guidelines that are harmonious with the preferences of the people involved. Discrete choice experiments are useful tools for eliciting preferences.Patients And MethodsThis study evaluated the preferences of patients and their relatives (n=285) to identify their priorities in organ allocation using a discrete choice experiment. In eight hypothetical allocation decisions, the participants were asked to select the candidate they considered the most suitable The candidates differed in years of life gained after transplantation, quality of life after transplantation, waiting time until transplantation, age, compliance and social support.ResultsThe most important aspects for setting priority in organ allocation were lack of compliance (β= -2.5, p<0.001) and good quality of life after transplantation (β = +1.4, p<0.001). The lack of social support (ß = -0.8, p<0.05) and the more years of life gained after transplantation (β = +0.5, p<0.001) had less but still a significant amount of influence on this decision, while the waiting list was not considered significantly important (β = 0.1, p>0.05). The comparison of the different relations to transplantation showed that life years gained after transplantation was of high relevance to posttransplant patients (+10 years: β = +0.709, p<0.001 / +15 years: β = +0.700, p<0.001) and of no importance to waitlisted patients (+10 years: β = +0.345, p>0.05 / + 15 years: β = +0.173, p>0.05) and relatives (+ 10 years: β = +0.063, p>0.05 / +15 years: β = +0.304, p>0.05).ConclusionThis study provides useful insights into the unique perspective of patients and their relatives on priority-setting in the allocation of donor organs that should be reflected in improved donor organ allocation rules.© 2023 Bartling et al.
