ABSTRACT
Introduction
Family carers have a key role in supporting malnourished older adults; yet, intervention evidence is lacking in the rehabilitation setting. This study aimed to explore the preliminary effects and acceptability of a family-centred, telehealth-enhanced dietary counselling intervention for treating protein-energy malnutrition (PEM) in rural-living older adults transitioning from rehabilitation to home, compared with usual care, in matched patient-carer dyads.
Methods
A pragmatic, historically controlled, prospective, two-arm non-randomised controlled trial was conducted as a pilot study. Fifteen malnourished older adults admitted to rural rehabilitation units in New South Wales, Australia, and their family carers, were recruited and matched to 15 historical controls. The Patient-Generated Subjective Global Assessment (PG-SGA) was the primary outcome for nutrition status assessed at rehabilitation admission, discharge, and 3 months post-discharge. Quality of life, physical function, length of stay, discharge location, institutionalisation, mortality, carer burden, and service satisfaction were secondary outcomes. The historical control group received usual care. The intervention group received a telehealth-enhanced dietary counselling intervention developed with co-design principles, which engaged the family carer as a partner in the nutrition care team, delivered during the rehabilitation admission and for 3 months post-discharge.
Results
The difference in PG-SGA score from baseline to 3 months post-discharge between the two groups was 3.46 (95%CI: −2.07, 9.01; p = 0.238). The intervention group had a higher proportion of patients who were well-nourished at 3 months post-discharge compared to controls (60% vs 13%). At 3 months post-discharge, the intervention group had lower odds of being rated malnourished or with more severe malnutrition (i.e., moderate vs. well-nourished, severe vs. moderate) on the PG-SGA (OR 0.01, 95%CI: 0.00, 0.27; p = 0.005). There was a trend towards the intervention group having reduced odds of being discharged to a location other than home (OR 0.18, 95%CI: 0.03, 1.07; p = 0.06). The intervention was perceived as acceptable to patients and family carers. There were no differences between groups in other outcomes.
Conclusion
Compared with usual care, the family-centred telehealth-enhanced dietary counselling intervention for the treatment of PEM in rural-living older adults transitioning from rehabilitation to home demonstrated preliminary efficacy and was acceptable to both patients and family carers. Future research aiming to improve PEM should meaningfully engage family carers as partners in the nutrition care team.
