Exploring Staff Attitudes Towards Unspecified Kidney Donors in the United Kingdom: Results From the BOUnD Study

Outcomes and motivations in unspecified (nondirected altruistic) kidney donation: Results from a United Kingdom prospective cohort study

Unspecified kidney donors (UKDs) increase the number of high-quality kidneys available for transplantation. This study aimed to determine whether the practice was acceptable, based on the noninferiority of donor physical and psychosocial outcomes when compared to specified kidney donors (SKDs). This longitudinal, prospective cohort study investigated potential living kidney donors from across all 23 UK adult kidney transplant centers. Participants completed validated questionnaires at 4 time points (recruitment, 2-4 weeks predonation, 3- and 12-months postdonation). Clinical outcome data were collected from National Health Service Blood and Transplant. Three hundred seventy-three (of 837 recruited; 45.7%) went on to donate (November 2016 to January 2021). There were no differences in donation rates (204 SKDs [54.7%] vs 169 UKDs [45.3%]; P = .944). Both groups reported being motivated by the desire to help someone (P = .157). Tests for noninferiority indicated that UKDs do no worse than SKDs on psychosocial or clinical outcomes over 12 months, and costs are similar (P > .05). This is the world's largest prospective observational study comparing SKDs and UKDs. It demonstrates no differences in primary motivation, donation rates, regret, cost, or psychosocial and physical outcomes. These data should reassure transplant professionals and potential donors and can bolster confidence in the practice around the world.

Assessing Health-Related Quality of Life in Non-Directed Versus Directed Kidney Donors: Implications for the Promotion of Non-Directed Donation

Living kidney donation has increased significantly, but little is known about the post-donation health-related quality of life (HRQoL) of non-directed donors (NDs) vs. directed donors (DDs). We thus examined the outcomes of 112 living kidney donors (82 NDs, 30 DDs). For the primary outcomes-namely, the mean physical component summary (PCS) and mental component summary (MCS) scores of the 12-item Short Form Survey (SF-12) questionnaire-scores were significantly higher for the NDs vs. the DDs (PCS: +2.69, MCS: +4.43). For secondary outcomes, NDs had shorter hospital stays (3.4 vs. 4.4 days), returned to physical activity earlier (45 vs. 60 days), exercised more before and after donation, and continued physical activity post-donation. Regression analyses revealed that donor type and white blood cell count were predictive of the PCS-12 score, and donor type was predictive of the MCS-12 score. Non-directed donation was predictive of a shorter hospital stay (by 0.78 days, p < 0.001) and the odds of having PCS-12 and MCS-12 scores above 50 were almost 10 and 16 times higher for NDs, respectively (p < 0.05). These findings indicate the safety and potential benefits of promoting non-directed donation. However, careful selection processes must be maintained to prevent harm and exploitation.
