Abstract Introduction Patients undergoing GI endoscopy often experience anxiety and due to limited health literacy. Traditional paper-based information leaflets are often not sufficient to accommodate for the diverse way in which people consume information. Public and patient involvement (PPI) and universal design for learning are two well-described pedagogical principles. We wanted to use these principles to design more effective patient education materials. Objectives Given the heterogeneity of resources available to patients, the authors wanted to develop a high-quality and trustable video resources for patients that would be available on our hospital website. These videos would be co-designed by patients and ancillary staff, through the formation of a key stakeholder panel. Results Using PPI principles, we were able to improve the relevance and quality of our content, through the use of storyboards and the expertise of the stakeholder panel. Through the three key UDL principles of multiple means of representation, engagement and action and expression, we were able to ensure that our videos were accessible and appropriate for all of our patients. Initial feedback from stakeholders and patients provided valuable insights, prompting necessary adjustments for accuracy and patient understanding. This comprehensive approach underscores the commitment to enhancing healthcare delivery. Our project is the first guide in combining both pedagogical principles in the development of patient information and education materials. Conclusions The meticulous steps taken, from stakeholder engagement to video production, reflect a commitment to inclusivity and patient-centred care. Ongoing evaluation and feedback mechanisms ensure continuous improvement, contributing to the overall success and sustainability of the digital service. Key messages • This is the first research/patient education piece designed using both PPI and UDL principles. • The importance of patient-centred educational design is key to improving health literacy and education in our patients.
