A Health Hackathon provides an opportunity for healthcare professionals to collaborate with IT developers and designers to solve health issues using technology and thus serves as a potential venue for interprofessional education. The present paper reports the views and experiences of participants on how the KKU mHealth Hackathon 2017 served as a venue for interprofessional education. A phenomenological approach was used involving semi-structured in-depth interviews of three faculty members and three students who participated in the hackathon. Participants expressed their learning experiences during the event, as well as factors that promoted or hindered learning. Our findings suggest that a health hackathon can serve as a suitable venue for interprofessional education as interviewees reported how they had learnt to successfully collaborate in interprofessional teams, move beyond their prior views and appreciate complementary work from other professions, focus on solving problems practically, and create a collegial, collaborative atmosphere. There were also some potential downsides of the hackathon that could be solved with an improved design in future occasions. A Health Hackathon can be an important opportunity for interprofessional education. Further studies should focus on methods to reproduce these positive learning experiences, mitigate the negative aspects, and investigate their long-term effects.
