The influence of socio-demographic factors, treatment perceptions and attitudes to living donation on willingness to consider living kidney donor among kidney transplant candidates

Abstract

Background. Living donor, compared with cadaveric donor kidney transplantation, is associated with prolonged graft survival and increased life expectancy for patients with end-stage renal disease (ESRD). However, access to living donor transplantation remains variable. Our objective was to further our understanding of the factors associated with the willingness to consider living donor kidney transplant (LDKTx). Methods. All patients from two tertiary care hospitals being assessed for a LDKTx (n=81), and a random sample of patients on the waiting list for a cadaveric kidney transplant (CDKTx, n = 133) were invited to participate. A mail survey assessed participants' socio-demographic characteristics, and perceptions of dialysis, CDKTx and LDKTx. Multivariable logistic regression was used to assess the influence of these factors on willingness to consider LDKTx. Results. Adjusting for patient age, employment status and number of close relatives, willingness to consider an LDKTx was independently associated with a lower perceived risk of peri-operative complications to the donor (adjusted OR 3.59, P = 0.02), the perception that the recipient would live longer following living donor transplantation (adjusted OR 4.34, P = 0.003) and greater perceived appropriateness of asking a family member to donate a kidney (adjusted OR 5.06, P = 0.007). Conclusion. Among the ESRD patients studied, adjusting for key factors that may be associated with access to LDKTx, perceptions about risks to the donor and benefits to the recipient were independently associated with a willingness to consider LDKTx as a treatment option. Provision of standardized comprehensible information about all treatment options to patients with ESRD may improve acceptance rates for living donor transplantation. © 2006 Oxford University Press.
