Evaluating the Quality and Readability of Online Resources on Unspecified Kidney Donation.

BACKGROUND

Unspecified kidney donation (UKD) refers to transplantation from donors unrelated and unknown to the recipient. UKD has contributed to the expansion of the live donor pool in several countries. The United Kingdom Transplant Community has set maximizing UKDs as a priority. The Internet raises awareness and potentially influences the decision-making regarding UKD. This is the first study assessing the quality and readability of online material on UKD.

MATERIALS AND METHODS

Google was searched for the terms "kidney donation" and one of "unspecified," "altruistic," "non-directed," "anonymous," or "good Samaritan," as well as "giving or donating a kidney to a stranger." Two independent assessors reviewed the top 100 websites. Quality was assessed using the Journal of the American Medical Association criteria, the DISCERN instrument and Health On the Net Code certification. Readability was assessed using the Flesch Reading Ease (FRE), Flesch-Kincaid Grade (FKG), and Simple Measure of Gobbledygook (SMOG) scores.

RESULTS

Only 6% of websites displayed HONcode certification. The mean (± SD) JAMA and DISCERN scores of 1.96 (± 1.00) and 32.34 (± 11.19) indicate poor quality. The mean (± SD) FRE, FKG, and SMOG scores of 52.92 (± 13.62), 10.60 (± 2.72), and 9.64 (± 2.22) reveal poor readability. The difference in JAMA and DISCERN scores according to website classification was significant (P < .001, P = .014) with websites from medical, nonprofit, and governmental organizations scoring amongst the lowest, while comprising most search results (61%).

CONCLUSIONS

Transplant centers and medical organizations should prioritize improving their online resources to lower the risk of individuals pursuing UKD based on unrealistic expectations or being discouraged unjustly.
