This article reflects on how patient education tool design can benefit from a co-creation process with patients and key stakeholders involved, using a case study in chronic obstructive pulmonary disease (COPD) care. Unfavourable hospitalisation experiences for COPD patients are often linked to organisational issues and health literacy challenges. This study presents insights from a year-long co-creation practice involving COPD patients, a family member, healthcare practitioners, and hospital managers, aimed at developing patient education tools to enhance health literacy concerning the hospitalisation process. The primary outcome is a set of patient education infographics that can be integrated into digital platforms or printed formats. For such co-creation practice, we found that setting clear creativity expectations and using methods such as user journey maps empower participants. Balancing the power dynamics between patients and healthcare practitioners enables culturally relevant and patient-centred tools. In addition, family members play a crucial role in both co-creation process and care journey, while hospital managers ensure tools align with clinical practices. We also advocate for an ecological perspective towards intervention development, acknowledging diverse needs emerged from the co-creation process. Future research should implement strategies in further individualising infographics to improve their effectiveness.
