BACKGROUND: Dietitians are increasingly working in residential aged care facilities (RACF). As such, supporting the RACF dietetic workforce is imperative. This qualitative study explored dietitians' experiences and preparedness for working in RACFs. METHODS: A qualitative descriptive approach from a non-singular reality relational position was used. Recruitment occurred through convenience and snowball sampling, including contacting a list of dietitians who had previously consented to be contacted for research. The interviews included a semi-structured approach. Data were analysed using constant comparison and reflexive thematic analysis. RESULTS: Thirty-one dietitians (n = 29 female; median age, 39 years) with a range of career experience participated in an interview. Interviews ranged from 25 to 68 min (mean duration, 41 min). Five themes and 13 subthemes were identified. Themes were: (1) joining the aged care workforce was not initially considered a career option, (2) difficulty sustaining satisfaction working in aged care, (3) navigating practical challenges working with residents while prioritising quality care, (4) poor acknowledgement of the dietitian role by staff and (5) grappling with a moral desire to improve the aged care sector. CONCLUSION: Dietitians face many challenges in fulfilling their role in RACFs, including RACF staff's poor understanding of dietitians' scope and a lack of procedural support for their daily activities. Dietitians report that genuine improvements in their job satisfaction and experiences of older adults require structural reform within the government, beyond their locus of control.
