Description of intervention(s) / exposure
Prehospital patients with major trauma induced shock treated by specialist prehospital medical teams (critical care physician and paramedic) will undergo usual (contemporary) treatment as directed by the treating physician.

There is no direct involvement for patients in this study as the entirety of their clinical care (and short term outcomes) are being directly observed. Clinical data (routinely collected data via medical records) will be collected over the first 30-days following injury

Statistical methods / analysis
Descriptive statistics will be used to describe the dataset. Normally distributed outcomes will be reported as mean plus or minus standard deviation, whilst non-normal data will be reported as median and interquartile range. Categorical data will be reported as counts and proportions. Ninety-five per cent confidence intervals will be constructed around all point estimates.

Exploratory multivariable regression and prediction modelling will be utilised to investigate which prehospital or early, in-hospital variables may be associated with early mortality in this cohort.
