Long-term, self-reported health outcomes in kidney donors

The wide use of healthy persons as kidney donors calls for awareness of risks associated with donation. Live kidney donation may impair quality of life (QOL) and result in fatigue. Long-term data on these issues are generally lacking in the donor population. Thus we aimed to investigate long-term self-reported health outcomes in a nationwide donor cohort.

We assessed self-reported QOL, fatigue and psychosocial issues after donation in 217 donors representing 63 % of those who donated 8-12 years ago. QOL was measured using the generic Short Form-36 Health Survey (SF-36), fatigue using the Multidimensional Fatigue Inventory (MFI) and psychosocial issues using donor specific questions. For each of the 8 domains of SF-36 and the 5 domains of MFI, we performed generalized linear regression.

Donors scored high on QOL with mean scores between 63.9 and 91.4 (scale 1-100) for the 8 subscales. Recognition from family and friends was associated with higher QOL scores in four domains. There were no significant gender differences. Fatigue scores were generally low. Females generally scored higher than males on all five dimensions of fatigue, although significantly only on two. Recipient still alive was associated with lower scores on mental fatigue. Regretting donors scored higher than average on all domains of fatigue. Recipient death, worries about own health and worsened relationship with the recipient influenced willingness to donate in retrospect. Donor age did not affect long-term health outcomes.

Eight till 12 years after donation QOL scores were generally high and improved with recogniton from family and friends. Fatigue was independent of donor age and more pronounced in females and in those who regretted donation.
