Patient willingness to pay for a kidney for transplantation.

While kidney transplantation is the most cost-effective treatment available for end-stage renal disease (ESRD) and affords patients with the best quality of life, the current supply of kidneys does not meet the demand. A potential solution to increasing the supply is to compensate living donors for a kidney. The purpose of this study was to describe ESRD patient willingness to pay for a kidney. Using a self-administered survey, 107 patients in 31 U.S. states completed the survey. The quantitative method and descriptive survey design employed descriptive, correlational, nonparametric and multivariate statistical tests to evaluate the data. Of participants, 78.5% were willing to pay for a kidney; there were significant correlations between gender, health status, household income, preferred source of a kidney and willingness to pay. Men, patients with poor and fair health status and those with household incomes > or =$50,000 were more willing to pay. Step-wise regression analysis found price and doctor's influence accounting for 52% of variance in willingness to pay. As price increased and doctor's opinion mattered, willingness to pay increased. This study supports development of additional studies with larger sample sizes and patients on kidney transplant waiting lists.
