Description of intervention(s) / exposure
This study will examine individuals presenting to the Fiona Stanley Hospital State Adult Burns Unit with less than or equal to 20% body surface area burn injuries, who are expected to undergo at least one surgery during inpatient admission. Participation will involve attendance at face-to-face in both an inpatient and outpatient capacity. Sessions will last approximately 90 minutes, involving a 1 hour follow-up after consumption of a 300ml glucose drink containing 75g of glucose, with observation of respiratory function post-consumption, as well as collection of a blood sample before and after glucose drink consumption, heart rate measurement via a wearable heart rate monitor, assessment of whole body free fat mass using bioimpedance electrodes, assessment of grip strength, and completion of two questionnaires. Each of these components will take approximately 5 minutes to complete. Assessment of energy expenditure using two devices will occur prior to surgery, which will add approximately 30 minutes to the initial session. The assessments will all be completed by a qualified Exercise Physiologist, except for the blood collection that will be drawn by a resident medical officer or phlebotomy accredited researcher.

These observation sessions will occur four times during participation in the study, spanning across a 12-13 month period. These sessions will take place 24-48 hours prior to surgery, 48-72 hours post surgery, 6 weeks post-surgery and 12 months post-surgery.

Outcomes
Primary outcome [1] 329123 0
Metabolic flexibility - determined by changes observed in respiratory exchange ratio (RER) as measured by sampling of expired gas using indirect calorimetry, post-consumption of the standardized high carbohydrate meal in the form of a 300ml glucose drink containing 75g of glucose.
Timepoint [1] 329123 0
RER will be measured for a continuous 60 minute period following the consumption of the standardised high carbohydrate meal at each assessment.

Baseline assessment: ~48 hours pre surgery
2nd assessment: 48-72 hours post surgery
3rd assessment: 6 weeks post surgery
4th assessment 12 month post surgery
Secondary outcome [1] 401542 0
Inflammatory markers - Interleukin 2 and 6, tumour necrosis factor alpha (TNF-alpha), C serum reactive protein (CRP) will be assessed from blood samples (plasma serum).
Timepoint [1] 401542 0
Baseline: 48 hours pre surgery

Secondary outcome [4] 401545 0
Blood glucose levels pre and post metabolic flexibility assessment (twice per testing session) using a point of care blood glucose monitor that will analyse a blood sample.

The metabolic flexibility assessment will involve the patient completing a 15 minute baseline respiratory assessment from expired gas, followed by the consumption of a 300ml glucose drink, followed by a subsequent 60 minute continuous respiratory analysis where expired gas will be analysed.
Timepoint [4] 401545 0
Blood glucose will be assessed immediately prior to the consumption of the standardised high carbohydrate meal, and will be assessed again 1 hour post-consumption at each assessment.

Statistical methods / analysis
The sample size for this study was calculated using a priori power analysis and identified 82 paired measures will be needed to observe an effect of 0.39 (from a previous study validating the COSMED Quark device) at a power of 80% and an alpha of 0.05. For the longitudinal aspect of the study, this will allow a significant drop off due, as only 45 participants are required for the analysis of the repeated measures across the 4 time points to determine a small change in RER of 0.15 with a power of 80% and an alpha of 0.05. This significant change in the latent sample size is expected and has been accommodated for in the estimation to account for drop off of the rural patients, which account for up to 50% of inpatient admissions, being unable to attend the 1 year follow up.

For statistical analysis of the data, descriptors of the participants will be preferentially presented as mean and standard deviation. The validation component of the study will be analysed using a Bland Altman plot to determine agreement between the two devices, with student paired t-tests being used for resting energy expenditure. For the repeated measures aspect one way repeated measures ANOVA will be used for the primary and secondary outcomes, with a paired sample t test also being used to determine the difference between pre and post surgery resting energy expenditure. All data analysis will be completed using the latest version of SPSS.
