Study type
Interventional
Description of intervention(s) / exposure
Currently, protein prescriptions for critically ill patients range from 0.5-3.8 g/kg/d. There is an insufficient evidentiary basis to establish which level of protein administration is right for which patient population. We will take usual practices (following the current ICU Nutrition guideline of Gold Coast Health) and create two groups randomising eligible patients to a lower prescription (equal to 1.2 g/kg/d) or to a higher prescribed protein intake (equal to 2.2 g/kg/d) for the duration of their ICU admission. Following randomisation, prescription according to group assignment will be undertaken by the ICU dietitian or ICU medical team with the intervention administered by ICU nurses as part of patient care practices. In both groups, targets will be set using pre-ICU dry actual weight. For patients with BMI greater than 30, ideal body weight based on a BMI of 25 will be used. For the higher protein group, we will use Nutrison Protein Intense (Nutricia; 10g protein/100ml) which provides a higher protein to energy ratio in line with current guidelines. The control group will receive Nutrison Protein Plus Multifibre (Nutricia; 6.3g/100ml). Enteral feeding solutions for both groups will be delivered as a continuous infusion. Once on the ward, protein supplementation will continue by providing high protein oral nutrition supplement (Resource 2.0; Nestlé Health Science) which will provide an additional 19.7g of protein in one 237ml supplement (an additional 40g of protein per day). In the event that flavour fatigue occurs, alternative protein supplementation will be prescribed using higher protein food supplements such as Up n Go Protein Energize (Sanitarium; 16.8g per serve), Quest Protein bars (Quest Nutrition; 21g protein), Chobani Fit high protein yoghurt (Chobani; 15 g). Intervention adherence in ICU is monitored as part of the clinical trial by reporting nutritional adequacy (proportion of prescribed nutrition received). When the patient is discharged to the ward, we will monitor (though chart audit and direct observation) the prescription, delivery and consumption of oral nutrition supplements in the intervention group to assess compliance with the study intervention. We will also collect consumption of ONS in the control group (both product and protein consumed) for the control group to assess the degree of treatment differentiation.
Although this trial is not about caloric dose, we want to encourage participating clinicians to be conservative in meeting energy targets and avoid overfeeding. Caloric goals should be the same in both groups. We will endorse the guidelines for energy targets set forth by American Society of Parenteral and Enteral Nutrition/ Society of Critical Care Medicine, especially as it pertains to the obese patient. For non-obese patients, we suggest that their caloric prescription be around 20-25 kcal/kg/day using a simple weight based formula. If the site chooses to use more sophisticated equations or indirect calorimetry, that is permissible. For obese patients, if indirect calorimetry is used, the goal of the nutritional prescription should be to provide energy not to exceed 65%–70% of measured requirements. If indirect calorimetry is unavailable or not used, consistent with the published guidelines, we suggest using the weight-based equation 11–14 kcal/kg actual body weight per day for patients with BMI in the range of 30–50 and 22–25 kcal/kg ideal body weight per day for patients with BMI >50.
In both groups, targets will be achieved through any combination of enteral nutrition (high protein content in high group if available), protein supplements, and parenteral nutrition or amino acids only (as clinically available). The only difference between the two groups is the protein targets that are set. Similar efforts should be used in both groups to achieve at least 80% of these targets. The remainder of care provided to eligible patients will be at the discretion of ICU providers.

Comparator / control treatment
Control patients receive 1.2 gram/kg/day of protein in the ICU and ONS on the ward as prescribed at the discretion of the treating team.
Additional protein supplements will not be given in the context of the study but may be prescribed at the discretion of the treating team. This information is included as part of our data collection strategy. The health service has a range of oral nutrition supplements which typically have approximately 19.7 g of protein per 237 mL.

Statistical methods / analysis
The feasibility outcomes (enrolment and consent rate, and compliance with outcome assessments) will be described by group as rates with 95% confidence intervals. As part of the screening procedures we will collect data on factors influencing recruitment and retention rates.

Intervention compliance (another feasibility outcome) will be determined by calculating the amount of protein consumed by the patient in ICU and again once the patient is on the ward. Prior to analysis, missing values will be described for all variables; all missing data and improbable values checked against source data. Nutritional adequacy at hospital discharge will be compared between the two groups using the rank-based Mann-Whitney U test, as we expect data to not be normally distributed. Secondary continuous outcomes will be analysed as described above. Categorical secondary outcomes will be analysed using Fisher’s exact tests. If >5% of outcome data are missing, multiple imputation will be used for the primary analysis and a ‘missing not at random’ sensitivity analysis will be performed using the tipping point approach of the pattern mixture model with multiple imputation.

Acceptability outcomes will be used to assess intervention acceptability, feasibility and to identify what factors helped or hindered adherence to intervention components. Qualitative data will be analysed using content analysis with an inductive approach.
We will provide secondary outcome data to the EFFORT trial where the data will be analysed following the procedures outlined for the cohort of patients in the EFFORT OUTCOMES substudy (Clinical trials.gov ID #NCT03160547).
Sample size and duration:
Given the main objective of the study related to feasibility, acceptability and intervention compliance we feel a sample size of 40 per group will allow us to assess these endpoints with reasonable precision and is consistent with the sample size of other Phase II studies. Based on the number of critically injured patients admitted to GCUH ICU each year (approx. 180 per year) we anticipate recruitment to take 3 years, with an anticipated consent rate of 50%.

Summary
Brief summary
Aim: To evaluate the feasibility of a randomised controlled trial of critically injured patients with nutrition risk factors where intervention group patients receive a higher dose (equal to 2.2 grams/kg/day) of protein/amino acid administration in ICU and a high protein oral nutrition supplement (ONS) on the ward; control patients receive 1.2 gram/kg/day of protein in the ICU and ONS on the ward as prescribed at the discretion of the treating team.
Secondary aim: To contribute ICU data to the EFFORT trial which, is a large, multicenter, pragmatic, registry-based, patient randomised, clinical trial of 4000 nutritionally high-risk critically ill patients. In this study the administration of lower dose of protein/amino acids (equal to 1.2g/kg/day) will be compared with the administration of a higher dose of protein/amino acids (equal to 2.2g/kg/day) to nutritionally high-risk critically ill patients to determine if higher protein administration is associated with greater muscle mass, improved survival and a quicker rate of recovery.
Hypothesis: We hypothesise that the trial will be feasible as judged by enrolment rates, intervention fidelity and protocol compliance
