*Purpose: ilearnKAS is a iteratively-designed patient-engaged mobile educational animated video developed with guidance from patients, providers, Self-efficacy and Multimedia Learning Theories designed for African American chronic kidney disease patients to increase knowledge and self-efficacy (capacity) to inform themselves about key concepts of kidney allocation.

*Methods: Kidney transplant candidates undergoing transplant evaluation at Erie County Medical Center between September-November 2018 (n=20) were shown the 2-minute video intervention. Kidney allocation knowledge, self-efficacy, and belief in allocation fairness were assessed immediately before and after the video.

*Results: The cohort was purposively derived to achieve 50% African American participation. Compared to pre-intervention, post-intervention mean scores were significantly higher for kidney allocation knowledge (Pre: 5.7±1.5; Post: 7.4±0.9, mean difference [MD]=1.7±1.5 p<0.001) for the entire cohort and amongst African Americans (MD=2.6±1.3, p=0.002), as well as across different levels of educational attainment, age, dialysis duration, health literacy/numeracy and technology access (Table 1). Perceived allocation fairness significantly increased post intervention (Pre: 2.7±0.7; Post: 3.0±0.5, p=0.03) and there was a trend toward increased self-efficacy (Pre: 5.5±1.2; Post: 5.9±1.0, p=0.06). Upon viewing ilearnKAS, most participants indicated agreement or strong agreement that the video was easy to watch (99%) and understand (95%), interesting or engaging (91%), trustworthy (94%), and that they would personally use (94%) and recommend the video to their social network (90%).

*Conclusions: ilearnKAS significantly improved patient capacity to understand key points about kidney allocation and was highly acceptable.
