RESUMO
BACKGROUND: A nondirected altruistic living kidney donor is a person who wants to donate a kidney to anyone in need. In 2010, the Spanish National Transplant Organization developed a national protocol to make the assessment of every potential nondirected living kidney donor. The aim of this study was to describe the potential donor pool and its characteristics and the overall effect of the program. MATERIAL AND METHODS: A retrospective analysis was performed using data from the Spanish National Registry of Transplant Activity, and the Nondirected Donors National Database, between 2010 and 2017. Data related to sociodemographic characteristics, main motivations toward donation, and causes of dismissal were collected from all potential donors. The assessment of each candidate was carried out in a step-by-step process based on the national protocol. RESULTS: Two hundred seventy-two people contacted us, showing interest in the nondirected kidney donation, only 203 people underwent the early triage, and 16 of them successfully completed the assessment proces s, representing 8% of the total. The main motivation toward anonymous donation (n = 161) was: social awareness (22%) and to improve the quality of life of other people (9%). One hundred eighty-two candidates did not proceed, due to medical and psychological contraindications (42%) or donor refusal after specific information about the donation process (33%). The number of utilized nondirected altruistic living donors was 13 out of 203 (6%) of the candidates who began the early triage. Twelve transplant chains and a direct donation were performed, which made 38 kidney transplants possible (2.9 transplants per nondirected donor). CONCLUSIONS: We have to continue working to optimize our program. Our next steps will be to review the evaluation process, to detect areas for improvement, to understand why we lost many possible donors, and to ascertain if any of the reasons could be avoided.
