BACKGROUND Fear of kidney transplant complications and incomplete information can lower transplant acceptance and preparedness. Our group developed 2 patient-centered educational animated videos on common kidney transplant complications to complement a previously developed video-based curriculum intended to promote kidney transplant access. MATERIAL AND METHODS We preliminarily evaluated the 2 animated educational videos at a single center using mixed methods. We conducted a before-and-after single group study with 22 patients after kidney transplantation to measure the videos' acceptability and feasibility to improve patient knowledge, understanding, and concerns of kidney transplant complications. Concurrently, we individually interviewed 12 patients before kidney transplantation about their perceptions of the 2 videos and analyzed the data thematically. RESULTS Knowledge of kidney transplant complications increased 10% (7.82 to 8.59, P=0.002) from before to after video viewing. Large effect size increases for knowledge were found for different strata of age, race, and health literacy. The mean total score for perceived understanding of kidney transplant complications increased after video exposure by 7% (mean 2.48 to 2.66, P=0.184). There was no change in kidney transplant concern scores from before to after video viewing (mean 1.70 to 1.70, P=1.00). After video viewing, all patients reported positive ratings on comfort watching, understanding, and engaging. Three themes of patient perceptions emerged: (1) messages received as intended, (2) felt informed, and (3) scared but not deterred. CONCLUSIONS Two animated educational videos about kidney transplant complications were well received and promise to positively impact individuals' knowledge and understanding, without raising excessive concerns.
