INTRODUCTION Interprofessional education (IPE) aims to prepare learners to work in collaborative health-care teams. The University of Otago, Wellington has piloted, developed and expanded an IPE programme since 2011. An interprofessional teaching team has developed alongside this programme. AIMS This study aimed to understand the development of a university-based interprofessional teaching team over a 4-year period and generate insights to aid the development of such teams elsewhere. METHODS Two semi-structured audio-recorded educator focus groups were conducted at key times in the development of the IPE programme in 2011 and 2014. The programme focused on long-term condition management and involved students from dietetics, medicine, physiotherapy and radiation therapy. Focus group transcripts were independently analysed by two researchers using Thematic Analysis to identify broad themes. Initial themes were compared, discussed and combined to form a thematic framework. The thematic framework was verified by the education team and subsequently updated and reorganised. RESULTS Three key themes emerged: (i) development as an interprofessional educator; (ii) developing a team; and (iii) risk and reward. Teaching in an interprofessional environment was initially daunting but confidence increased with experience. Team teaching highlighted educators' disciplinary roles and skill sets and exposed educators to different teaching approaches. Educators perceived they modelled team development processes to students through their own development as a team. Interprofessional teaching was challenging to organise but participation was rewarding. Programme expansion increased the risks and complexity, but also acted as a stimulus for development and energised the teaching team. DISCUSSION Interprofessional teaching is initially challenging but ultimately enriching. Interprofessional teaching skills take time to develop and perspectives of role change over time. Educator team development is aided by commitment, understanding, enthusiasm, leadership and trust.
