The main goal of interprofessional education (IPE) is to improve services and the quality of care for patients, their families, and communities. Enabling different professional learners, or others with relevant care roles, to learn together, is expected to advance care delivery. For both pre and post-registration learning, it therefore follows that listening to and working with service users is essential to underpin interprofessional learning. We completed a scoping review to identify how service users were involved in the design, delivery, and management of IPE. We searched the literature from the rise of curriculum alignment for IPE in 2000 to 2023, we identified 13 papers. Our analysis of these 13 papers showed that pre-registration students appreciated learning from service users’ experiences of care but often the user input was not combined with a deeper appreciation for what this means for effective interprofessional practice. Post-qualified clinical teams involved service users in the design and development of services, often with care and support. Theoretical understandings about service user involvement in IPE for how learning took place or to explain the concepts involved, were limited. Where service users were involved in IPE, there was often little support with little attention to the skills of interprofessional facilitation. Theoretically informed research on the involvement of the service users voice in IPE requires further consideration.
