With an ageing population requiring ongoing health care, the frequency of hospital visits continues to rise. Within these settings, malnutrition among the elderly is a well-recognised problem, which requires dietetic intervention. While the importance of addressing malnutrition through dietetic interventions are well recognised, due to lack of timely identification, competing clinical priorities, staffing issues, it is often not addressed. This is especially the case in rural and remote areas where access to care may be limited due to staffing and resource limitations. Dietetic assistants (DAs) could assist in tackling malnutrition and this project tested this new model of care.


A systematic scoping literature search was undertaken to identify the evidence for the role of DAs. A comprehensive change management strategy was adopted. A targeted training package was developed for and delivered to DAs within a large tertiary hospital by a senior dietitian. Qualitative and quantitative data were collected to demonstrate the impact of DAs across a range of measures.


The literature evidence (n=5) highlighted the positive impact on acute patient nutritional intake, anthropometric indices and ability to assist in reducing mortality. Qualitative interviews with DAs (n=3) and dietitians (n=4) revealed support for this role in practice. Quantitative data indicated improved access to dietetic care and timely intervention with patients (n=25) satisfied with the DA interactions.


Despite these positive findings, implementing a new model of care was fraught with challenges. While health reform and innovation continues to be at forefront, effectively translating these into practice continues to face barriers.
