Description of intervention(s) / exposure
Active participants in high fidelity simulation exercises that are a routine component of NSW Aeromedical Operations 6-monthly induction training. These exercises are of 45 to 60 minutes duration. They involve the use of actors as patients, or mannakins if procedures are required to be performed; as well as paramedics or paramedic students as ambulance staff. Real-time patient observations (ECG, HR, SBP, ETCO2) are provided to teams through an i-simulate patient monitor. Scenarios include interhospital transport scenarios such as difficult staff interaction, unanticipated airway problems, as well as prehospital exercises such as severe combative head injuries, trapped patients and traumatic cardiac arrest. Participants are expected to behave as they would in real-time (eg no sudden jumps in time or forced urgency)

Not applicable
Comparator / control treatment
Directed observers in high fidelity simulation exercises that are a routine component of NSW Aeromedical Operations 6-monthly induction training. The directed observers observe the same scenario as the active participants, The 'directed' obersevation means that observers may be given specific areas of feedback to observe, or questions to answer as the scenario progresses.

Active

Outcomes
Primary outcome [1] 318624 0
The perceived performance capacity, measured using the NASA-TLX (task load index), of active participants and directed observers
Timepoint [1] 318624 0
immediately following high-fidelity simulation education activities
Primary outcome [2] 318625 0
The perceived performance capacity, measured using the NASA-TLX (task load index), of active participants and directed observers
Timepoint [2] 318625 0
following three months of clinical experience after training is complete.
Secondary outcome [1] 365533 0
Participants’ perceived self-efficacy . This will be measured using a modification of an established self-efficacy questionnaire obtained from the literature on simulation education (Watters C, Reedy G, Ross A, et al. Does interprofessional simulation increase self-efficacy: a comparative study. BMJ Open 2015;5:e005472. doi:10.1136/ bmjopen-2014-005472 )
Timepoint [1] 365533 0
At baseline (the start of GSA-HEMS induction), completion of GSA-HEMS induction and 3 months post completion of induction.

Statistical methods / analysis
Analysis will be performed using the statistical software package R (R Core Team, Vienna, Austria). 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.
The self-efficacy questionnaire will be analysed using descriptive statistics only.
The NASA-TLX will be analysed first by converting the participant’s selection to a 100-point scale (1 graduation = 0.5 point). To compare directed observers and active participants at induction, a repeated-measures ANOVA will be used with participant as the within-subjects factor and simulation role (observer/participant) as a between-subjects factors. The comparison of induction course and clinical work by a repeated-measures ANOVA, with participants as the within-subjects factor, and phase (induction / clinical work) as between-subjects factors will be performed. Prior to performing this ANOVA, a missing data analysis will be conducted to check compliance with completing the NASA-TLX

Summary
Brief summary
High fidelity simulation education (HFSE) is a commonly employed tool within critical care medicine, however, in practice, simulation education is cost and resource intensive This has resulted in the necessary incorporation of observers in HFSE, and increased interest in whether observers can be expected to benefit from this experience, and what factors might increase the benefit of observer participation. Consequently, this study seeks to answer two questions. First, are the experiences in simulation similar for directed observers and active participants? Second, does the HFSE provide a similar experience to clinical work?
We will asses this using two qualitative measuring tools, the NASA Task Load Index and a self efficacy questionnaire, in a repeated measures design with these instruments used in induction and also after a period of clinical work.
