The market penetration of eHealth interventions is substantially lower than investors anticipated due to their low acceptance. Main causes include the use of top-down approaches and the tendency for research to concentrate on technology rather than service delivery from users’ perspective. Healthcare professionals have exclusive expert knowledge of evidence-based practice in a specific area, which may explain why many eHealth intervention development projects continue to use top-down approaches. It is therefore crucial to empower healthcare professionals with design skills and mindset. On the otherhand, the roles and responsibilities of designers in the twenty-first century have been controversial. Many farsighted designers assert that we are at a turning point of transforming design from an expert driven process focused on objects and services within a taken-for-granted social and economic order towards design practices that advocates design-led societal transition toward more sustainable futures. To foster the transformation, design education should cater to all abilities. Health CASCADE is a MarieSklodowska-Curie Innovative Training Network to consolidate co-creation as an effective tool to fight public health problems. Imparting the knowledge of co-creation in public health to healthcare professionals has the potential to alleviate the gap between design and healthcare, meanwhile provides opportunities for stakeholder participation in the development process to increase trust. This paper illustrates a curriculum development process partnered with a healthcare professional aiming for delivering knowledge of co-creation in public health to healthcare professionals working on designing eHealth programmes on the national healthcare support platform, 1177.se – Support and Treatment in Sweden.
