Description of intervention(s) / exposure
All-SPICE will be a prospective parallel-group multi-centre observational substudy of SPICE-III utilising the the SPICE-III study screening. The SPICE-III study (NCT01728558) is a prospective, un-blinded, randomised controlled trial of Early Goal-Directed Sedation compared with Standard care and will recruit 4000 patients worldwide. The SPICE-III study will recruit patients who are intubated and ventilated in a participating ICU, are expected to remain intubated the day after enrolment and need immediate and ongoing sedation.

Following recruitment, patients will be randomised to either the intervention arm, Early Goal-Directed Sedation (EGDS) or the control arm, standard sedation practice (STDS).
Patients in the EGDS arm will receive a dexmedetomidine infusion starting at 1 mcg/kg/hr without loading dose to achieve a target Richmond Agitation Sedation Scale (RASS) [10] -2 to +1 at all times, unless otherwise clinically indicated. If dexmedetomidine alone is insufficient, propofol will be administered, by bolus or infusion (10-70 mg/hr) or both, to achieve the targeted level of sedation.
Patients in the STDS will receive sedative medications (either midazolam or propofol or both), as determined by the treating clinician, to achieve clinically appropriate sedation target as chosen by the treating clinician, although a target of RASS -2 to +1 is encouraged (default) at all times in this arm.

Patients enrolled in the SPICE-III study will be eligible for inclusion in the All-SPICE sub-study. A total of 100 patients from approximately 4 ICUs will be enrolled in All-SPICE. Immediately following randomisation on day 1, patients will have blood samples taken, which will be repeated on days 2, 4 and 6.

Statistical methods / analysis
General principles
All analyses will be based on the intention-to-treat principle. As no sequential or interim analyses are planned, a P-value less than 0.05 will be used as the level of significance throughout.

Trial profile
All patients who provide informed consent will be accounted for in the final statistical report. A CONSORT- style flow diagram will illustrate patient progression through the trial from initial screening for eligibility to completion of the final primary outcome assessment. Number (percentage) by treatment group will be given for patients in the ITT population, reasons for study withdrawal, and major protocol deviations and violations.

Demographic and baseline characteristics
Patient demographics and baseline characteristics will be presented according to treatment group. Discrete (binary and categorical) variables will be summarised as percentages with the denominator stated when data are missing. Continuous variables will be summarised according to their underlying distribution. Normally distributed data will be presented as mean (SD) whilst non-normal data will be presented as median (IQR). Ranges (minimum, maximum) for each variable will be supplied in an appendix to the paper.

Analytical methodology
Data distributions will be checked for normality using a Shapiro-Wilk test.
For demographic and baseline data, differences between groups will be assessed using either a two-tailed t-test for normal data or a Mann-Whitney test for non-normal variables.
The effect of treatment allocation constitutes a repeated measures series and will be analysed as a longitudinal and correlated dataset using a mixed effect general linear model. A mixed effect model is preferred as there are elements of fixed effect (e.g. age, gender, weight) and random effect (e.g. inotrope dose, sedation strategy) in the dataset. Models will examine the effect of treatment allocation on the components of the stressor panel. Survival time will be analysed using Cox regression with the results presented as Kaplan-Meier plots.
Mortality data will be analysed using multivariable logistic regression adjusted for important predictors of outcome (e.g. age, gender, APACHE score, admission source, stress panel components etc.). Significant predictor variables will be identified by sequential elimination with a likelihood-ratio test performed between successive iterations.
Regression results will be presented as the regression slope (beta), the level of significance of that slope (P-value) and the coefficient of determination for the model (R2). A slope significantly different from zero will be interpreted as a significant rise (positive slope) or fall (negative slope) of the variable under consideration over time. The coefficient of determination relates to the proportion of rise or fall in the variable under consideration that is explained by the timebase.

Calculation of numbers required
As there are no data upon which to base a rigorous calculation of the numbers required, a total of 100 was arbitrarily chosen as being likely to be both sufficient and practical in the time permitted for the study.

Data presentation
Data will be presented in both tabular and graphical format with estimates of central tendency, precision and level of significance.

Subgroup analyses
Whilst no subgroup analyses are planned, should they occur they will be treated as supplementary and exploratory with the intention of generating new hypotheses.

Statistical tools
Stata (version 14.1) will be used for all analyses
