Canadians' attitudes toward corneal donation: informational-motivational videos increase willingness toward corneal donation

      Abstract

      Objective

      To assess the knowledge of corneal transplantation, willingness toward corneal donation, and the efficacy of a short informational and motivational video in increasing the willingness toward corneal donation among Canadian adults.

      Methods

      Cross-sectional interventional study. A survey targeted Canadian adults, assessing their knowledge and attitude toward corneal donation and the efficacy of a 1-minute-long informative and motivational video on increasing willingness toward corneal donation.

      Results

      The survey was accessed by 1361 individuals and 1013 completed the questionnaire (74% completion rate). The sample consisted of 36% males and 64% females, with an average age of 37.0 ± 15.3 years. The majority (58%) thought to lack basic knowledge about corneal donation. Similarly, objective knowledge of corneal donation was relatively low, with an average score of 7.8 ± 4.5 (out of 20). In our sample, 44% had not opted-in for organ donation, among whom willingness to donate one's own cornea increased from 59% pre-video to 79% post-video (relative increase of 34%; p < 0.001). Lack of awareness about the benefits of corneal donation was the most commonly cited reason for unwillingness to donate.

      Conclusions

      The results demonstrated a general lack of awareness of corneal donation among the Canadian population and highlighted the efficacy of a short informative and motivational video in increasing willingness to donate corneal tissue. With lack of awareness about the benefits of corneal donation being among the primary reasons for the unwillingness to donate, simple but efficacious interventions via informative and motivational videos can increase tissue donors and help reduce corneal tissue shortage.

      Résumé

      Objectif

      Évaluer les connaissances en matière de transplantation cornéenne, l'intérêt envers le don de cornée et l'efficacité d'une courte vidéo instructive et incitative destinée à des Canadiens d’âge adulte en vue d'accroître leur volonté de faire un don de cornée.

      Méthodes

      Étude d'intervention transversale comportant un sondage auprès de Canadiens d’âge adulte visant à évaluer leurs connaissances et leur attitude quant au don de cornée, de même que l'efficacité d'une vidéo instructive et incitative d'une durée de 1 minute visant à stimuler leur intérêt envers un tel don.

      Résultats

      Sur les 1361 personnes qui ont accédé au questionnaire, 1013 personnes y ont répondu (taux de réponse de 74 %). L’échantillon regroupait 36 % d'hommes et 64 % de femmes, et l’âge moyen était de 37,0 ± 15,3 ans. La majorité des répondants (58 %) estimaient ne pas avoir de connaissances générales sur le don de cornée. De fait, les connaissances objectives à cet égard étaient relativement faibles : le score moyen s’élevait à 7,8 ± 4,5 (sur 20). Dans notre échantillon, 44 % des sujets n'avaient pas consenti au don d'organes; de ce nombre, la volonté de procéder à un don de cornée est passée de 59 % avant la vidéo à 79 % après la vidéo (augmentation relative de 34 %; p < 0,001). Le manque de connaissances quant aux bienfaits du don de cornée était la principale cause de réticence des participants à faire un tel don.

      Conclusions

      Les résultats ont mis au jour un manque de connaissances générales en matière de don de cornée chez des Canadiens et ont souligné l'efficacité d'une courte vidéo instructive et incitative en vue d'accroître leur volonté de faire un tel don. Le manque de connaissances quant aux bienfaits du don de cornée compte au nombre des principales raisons expliquant la réticence des participants à faire don de leur cornée. Des interventions simples, mais efficaces, prenant la forme de vidéos instructives et incitatives peuvent accroître le nombre de donneurs et, par conséquent, réduire les pénuries de tissu cornéen.
