To investigate the nature of public preferences in the allocation of donor
liver grafts for transplantation a social conjoint analysis (CA) technique
was developed for a questionnaire survey. A convenience sample of academic
and non-academic employees of a British University were invited to particip
ate in the survey. Respondents were presented with eight choice situations
in which they were asked to allocate 100 donor liver grafts between two gro
ups of 100 individuals in urgent need of a transplant. The groups of indivi
duals differed in terms of the length of time spent waiting, the life years
gained following transplantation, age, personal responsibility for their i
llness and whether they were primary or re-transplant candidates. Only two
respondents (0.7%) consistently chose to give all of the donor organs to th
e group of individuals with the highest expected length of survival whilst
seven respondents (2%) exhibited strict egalitarian preferences, allocating
equal numbers of donor organs to both groups irrespective of their charact
eristics. The vast majority of respondents indicated that they would be pre
pared to sacrifice some gain in the efficiency of the transplantation progr
amme for an increase in equity or fairness in the allocation of donor liver
s. Using social CA it was possible to establish the relative weight attache
d to each characteristic in determining individual's allocation decisions.
