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.

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.

Summary
Brief summary
The main aim of this study program will be to develop the current understanding of the chronic stress response to a non-severe burn injury (less than or equal to 20% total body surface area (TBSA)) in adult patients, with the addition of the novel approach of metabolic flexibility assessment to better characterise this response. Specifically, we aim to determine the interaction of the systemic metabolic, inflammatory, musculoskeletal and cardiovascular responses, aiming to present a compete image of the chronic response post non-severe burn injury, as well as the effects of common treatments in the form of surgery and nutritional support.

The primary objective of this study will be to determine the state of metabolic flexibility in acute non-severe burned patients (less than or equal to 20% TBSA) across a 12-month period of analysis of recovery at four time points.
Secondary objectives of this study will be to analyse the acute stress response of non-severely burned patients across the same 12 month period post injury, looking specifically at metabolic, inflammatory, musculoskeletal and cardiovascular responses, as well as to examine the acute effects of surgical intervention on metabolic rate in non-severely burned patients.

We hypothesise that non-severely burned patients will experience a state of metabolic inflexibility throughout their post injury recovery, while also displaying a similar physiological stress response to what is seen in larger burns injuries.
