Background The participation and success of university health students in rural areas is critical in addressing the maldistribution of the rural health workforces internationally. Particular attention to the experiences of mature-aged health students is needed to build a sustainable rural health workforce, given the higher proportions of mature-aged university students in rural, regional and remote areas compared with metropolitan areas and rural mature-aged students wanting to stay in their communities. However, little is known about the kinds of supports rural mature-aged students require to succeed with their studies.Methods Drawing on rural standpoint theory and using structural inequality as a retention lens, we explored the current and potential supports that rural mature-aged nursing and allied health students require to successfully participate and complete their pre-professional university course. A Stakian multicase study was undertaken with cases at three rural university campuses in Australia. The data collection was primarily qualitative, with semi-structured interviews, campus surveys and focus groups involving 36 participants (including students, academic and professional staff, and placement supervisors).ResultsThis study found supports were provided formally and informally by the university, by the community and manifested by students. Several support gaps as well as potential supports to alleviate them were identified. These include formally acknowledging the mature-aged cohort and their diverse experiences and non-university commitments; fostering connections between mature-aged students; making university affordable; preparing mature-aged students for university; adapting course content and delivery; and restructuring placements for mature-aged students.ConclusionsWe argue that rural mature-aged nursing and allied health students require supports that are age-specific, appropriate to the community context, and harness existing relational processes of rural university campus activity. Rural university campuses need to involve rural mature-aged students and other stakeholders relevant to each context in the process of identifying and implementing student supports for this cohort.
