Abstract
BACKGROUND: No studies using a valid, standardized method to measure post-donation satisfaction levels among living kidney donors (LKDs) have been published. METHODS: Donor satisfaction levels were measured using the Japanese version of the Client Satisfaction Questionnaire-8 (CSQ-8), a validated, self-report questionnaire. To identify factors related to post-donation satisfaction levels, we compared donors' sociodemographic and psychological characteristics and health-related quality of life (HRQoL), using the Short Form-36 Health Survey (SF-36), as well as recipients' clinical characteristics and SF-36 scores between donors with and without low satisfaction. In addition, donors' perceptions of the donation results and transplant procedure were assessed using measures that we developed. RESULTS: The mean (standard deviation [SD]) CSQ-8 score for the 195 participants was 26.9 (3.4). Twenty-nine (14.9%) respondents with total scores < 1 SD below the mean CSQ-8 score were placed into the low satisfaction group. Multiple logistic regression analysis demonstrated that lower perceptions of receiving adequate information prior to transplantation (odds ratio [OR] = 0.17; 95% confidence interval [CI] = 0.079-0.379; p < 0.001), lower optimism according to the Life Orientation Test (OR = 1.24; 95% CI = 1.045-1.470; p = 0.014), and increased serum creatinine levels in the paired recipient (OR = 0.05; 95% CI = 0.250-1.011; p = 0.054) independently increased the odds of having less satisfaction with donation. CONCLUSIONS: Our findings suggest that careful pre-donation education and more detailed informed consent may be needed, especially in LKDs with low constitutional optimism.
