BackgroundIn Australia, university clinical programs rely heavily on external healthcare professionals to provide a range of authentic clinical training and professional development opportunities for students. There is, however, a limited understanding of the factors that motivate these professionals to be educators and whether this varies across different healthcare disciplines within Australia. As the demand for clinical placements continues to increase, it is critical for the ongoing success of these programs that universities identify both the barriers associated with teaching and the benefits that enhance job satisfaction.MethodsA two-part questionnaire was emailed to 849 external healthcare educators teaching predominantly in Medicine, Medical Imaging, and Optometry programs at Deakin University. Part-one surveyed the socio-demographics, perceived benefits, and barriers to teaching, plus the utilisation of entitlements offered by the university. Part-two was modelled on Dybowski and Harendza’s validated Physician Teaching Motivation Questionnaire (PTMQ) and adapted to an Australian audience.ResultsOverall, 776 out of the 849 questionnaires were considered in the final participant pool. The response rate for part-one was 19.7% (n = 153/776) and 18.3% (n = 142/776) for part-two. Across all professions, altruism was the primary source of motivation for teaching in Deakin University’s healthcare programs. Medical Imaging educators placed a higher value on career-related teaching aspects compared to those in Medicine and Optometry (p < 0.003). The resources and benefits associated with teaching were generally perceived to be of minimal importance. External healthcare educators most commonly reported that there were no barriers to teaching (41.3%, n = 78) however, increased workloads and time constraints were the next most likely factors to affect teaching participation (31.8%, n = 60).ConclusionOur validated adaptation of the PTMQ successfully targeted healthcare professions not focussed on by Dybowski and Harendza. Altruistic motivation was the overarching theme for why Australian external healthcare educators contribute to teaching with some differences in career-driven motivation additionally acknowledged. Despite there being no key benefits or barriers to teaching participation, universities must remain cognisant of the factors that influence the recruitment and retention of external healthcare educators and how to optimise these for the ongoing success and sustainability of their teaching programs.
