Comparator / control treatment
Once enrolled and baseline data collection is performed, the participants will be placed on a high energy and high protein diet which includes one 1kcal/ml oral nutrition supplement per day. The high energy high protein diet alters the menu choices for an inpatient to eliminate energy and protein poor options. Participants will only receive individualised medical nutrition therapy by the rehabilitation dietitian if referred by the rehabilitation team as part of usual care. The participant will receive inpatient follow-up and intervention within the time and resource restraints typical to a rural rehabilitation unit in NSW, however will not receive any post-discharge follow-up from the rehabilitation dietitian. The intervention delivered by the rehabilitation dietitian will not typically involve informal carers, but may involve community dietitian referrals and registration for discounted oral nutrition supplements (ONS) once the participant is discharged. Follow-up for older adults once discharged is minimal due to resource restraints and high waiting times for community consultations. The rehabilitation dietitian is not a study investigator and their involvement with study participants will be monitored by the primary researcher in the medical notes.

Eligibility
Key inclusion criteria
Study centres were chosen by convenience sampling based on location. Patients greater than or equal to 65 years admitted to the participating rehabilitation units with a patient-generated subjective global assessment (PG-SGA) rating of B (mild-moderate malnutrition) or C (severe malnutrition), if they were community-dwelling residents prior to admission with the view they would be discharged back to the community and they have an acknowledged informal carer. This includes community-dwelling patients transferred from acute care. An informal carer for this study was considered an adult family member or close friend who a) lives with the older adult or b) does not live with the adult but provides care to the older adult for four days or more each week. The details of the carer will be provided by the participant in the first instance and reaffirmed by the informal carer.
Minimum age

Can healthy volunteers participate?
No
Key exclusion criteria
Well nourished (PG-SGA rating A) patients are excluded. If it becomes apparent that a participant will have their discharge location changed from the community to a residential aged care facility, they will be included with an intention-to-treat approach however will not receive final outcome assessments. Informal carers will be invited to participate in the study in order to complete secondary outcome measures; however their non-participation does not excluded eligible older adults from participating in the study.

Statistical methods / analysis
Sample size: The scored patient generated subjective global assessment (PG-SGA), the primary outcome measure, was considered as a continuous variable with an expected standard deviation in the control group of 6.0. Assuming that the minimum difference of interest across comparison groups is 4, then 48 subjects per group will be required to detect this difference with 90% power and type I error of 5% or less (two-tailed). Assuming an attrition rate of 30% over 90 days, and allowing 15% extra for the application multivariable modelling techniques to adjust for confounding, 96 x 1.3 x 1.15 = 144 subjects need to be approached to retain 110 subjects by the end of the study.
The results will be analysed with an intention to treat approach. Potentially confounding variables to be included in multivariate models include: age (continuous), gender (dichotomous), polypharmacy (Y/N; dichotomous), education level (secondary/tertiary/trade; categorical) and the modified mini-mental state score (continuous). Any confounding variables found to correlate strongly will be combined for use in multivariate models. Descriptive statistics (mean +/- standard deviation, median and interquartile range) will be used to characterise potentially confounding variables not included in multivariate models, the sample population, non-participants, lost-to-follow-up, and to report process evaluation. Normality will be assessed using the Shapiro-Wilk test and homogeneity of variance using a scatterplot. If data is skewed, log transformations and parametric tests will be applied. If the data is unable to be transformed to improve the distribution, the appropriate non-parametric tests will be used.
Outcomes will be compared at three time-points (T1, T2, T3) for nutrition status and, weight. Quality of life and physical function will be compared at discharge and 90 days post-discharge (T2 and T3). One-off measures will be compared between groups at that time point only, for example length of stay (T3).
The Chi-squared test and analysis of variance (ANOVA) will be used to compare categorical and continuous data per group allocation (control and intervention) at each relevant time-point. Nutrition status and weight will also be assessed for within-subject changes over time using mixed linear models. Logistic regression will be used to calculate relative risk ratios for categorical dependent variables (MBI category, discharge location, hospitalisation and institutionalisation post-discharge) and multiple linear regression will be used to assess continuous dependent variables (scored PG-SGA, MNA, weight, AQoL-6D score, length of stay and hospital admissions) for comparison between groups (intervention and control).

Summary
Brief summary
The MARRC Study aims to address the gaps in current evidence for the prevention and treatment of malnutrition in older adults. The project aims to answer: “Among malnourished older adults admitted to rural rehabilitation units in New South Wales (NSW), Australia, does engaging the informal carer as part of nutrition support improve nutrition status, functional status, quality of life, rehabilitation outcome (length of stay and institutionalisation), incidence of hospitalisation and cost-effectiveness of care at discharge and 90 days post-discharge compared with usual care?”
The intervention involves nutrition intervention, which is a one off counselling session involving the patient and their informal carer and post-discharge telephone reviews for the informal carer. The control group receives standard care, which does not involve the informal carer or post-discharge support.
