Description of intervention(s) / exposure
Oral nutrition supplements - Fortisip Compact Protein
This is a pilot comparative effectiveness trial of low volume oral nutrition supplements (Fortisip Compact Protein, 2 x 125mL/day) vs standard oral nutrition supplements (Ensure Plus, 2 x 200mL/day).
The dose of the intervention product (Fortisip Compact Protein) is 125mL twice daily. The duration of its administration is 3-4 days (depending on hospital inpatients' length of stay). The mode is oral solution (milky-type drink). A research assistant will monitor adherence by collecting and weighing supplement drink containers after patient consumption. The intervention supplement differs to the standard supplement by volume (125mL vs 200mL) and protein content (18g per serve vs 12.5g per serve). Energy content is the same for both products (1263kJ per serve).

Outcomes
Primary outcome [1] 334647 0
Standard deviation (SD) of the intended primary outcome for a definitive trial (% grams wastage of oral nutrition supplements) to estimate sample size required for a definitive trial. To assess this, supplement bottles will be collected by researchers and weighed using digital scales to calculate the grams consumed / grams wasted.
Timepoint [1] 334647 0
Supplement wastage will be measured twice daily (after patient consumption of each prescribed supplement - 2 per day) by weighing the supplement container. This will occur for three days post-randomisation.
Secondary outcome [1] 421516 0
Oral nutrition supplement wastage (% grams wasted) between groups will be determined by a researcher collecting supplement bottles and weighing them using digital scales to calculate the grams consumed vs grams wasted.
Timepoint [1] 421516 0
Measured daily (by weighing oral nutrition supplement containers) for 3 days post-randomisation
Secondary outcome [2] 421517 0
Patient energy (kJ) intake of oral nutrition supplements between groups. This will be calculated by weighing supplement containers after consumption using digital scales and calculating energy consumed based on the product's nutritional information panel.
Timepoint [2] 421517 0
Daily for 3 days post-randomisation (calculated from data collected for secondary outcome 1)
Secondary outcome [3] 421859 0
Patient protein (grams) intake of oral nutrition supplements between groups. This will be calculated by weighing supplement containers after consumption using digital scales and calculating protein consumed based on the product's nutritional information panel.
Timepoint [3] 421859 0
Daily for 3 days post-randomisation (calculated from data collected for secondary outcome 1)

Efficacy
Statistical methods / analysis
The primary aim of this pilot study is to accurately determine the standard deviation of the primary outcome, % grams of wasted Ensure Plus (control) oral nutrition supplement (ONS), to enable a reliable estimate of the sample size required for a full comparative effectiveness trial (CET). A secondary aim is to gain a clinical understanding of the difference in % grams wasted between Ensure Plus and a smaller volume ONS as an effect such that we can propose a minimum clinically important difference in % grams wasted. However, as the study procedure for the pilot study will be identical to that for the full CET, it is possible to roll the results obtained in the pilot into the subsequent CET. We can also estimate a sample size for the pilot that will optimize the sample size for the complete study by the method described by Whitehead et al. (2016). Based on a two sample t-test, for the main trial to have a power of 90% at a significance level of 0.05 and to detect a standardized effect size that would be considered small, we will need 25 participants in each arm of the pilot trial.
For the pilot’s secondary outcomes (i.e. the primary and secondary outcomes of the larger CET), all quantitative data will be entered into SPSS and a 10% random data check will be done to identify any errors. Demographic data will be presented using descriptive statistics (i.e., number/percent and mean/standard deviation [or median/interquartile range for non-normally distributed data]). ONS wastage (and compliance) and energy and protein provided by ONS will be compared between groups using t-test or non-parametric equivalent. Patient satisfaction, nutritional and hospital outcomes will also be compared between groups using t-test or chi-squared test (or non-parametric equivalents).
