Design outcomes

Primary

Measure	Time frame
Step & error metrics measured using analysis of videos of anaesthetist's performance of interscalene block by independent, trained raters 1 week and 6 weeks after training.	—

Secondary

Measure	Time frame
1. The number of eye gaze fixations and the number of glances are measured using eye tracking glasses at the end of cadaver and training and at the end of clinical testing 1 week and 6 weeks after training 2. A nine-point validated global rating scale (GRS) for summative assessment is measured at the end of clinical testing 1 week and 6 weeks after training 3. Quality of anaesthesia (using preoperative and hourly recovery room pain scores at rest and movement using a 100-mm visual analogue pain scale; onset and distribution of sensory and motor and time to readiness for surgery) is measured during clinical testing 1 week and 6 weeks after training 4. Patient experience using a 100-mm anchored scale for pain and paraesthesia experienced is measured during clinical testing 1 week and 6 weeks after training 5. Technical difficulty measured as the number of multiple needle insertions and skin puncture sites is measured during clinical testing 1 week and 6 weeks after training 6. Trainee self-efficacy and mood is measured using a 100-mm anchored scale before and after training blocks on the soft embalmed cadaver 7. Number of steps and errors metrics is measured on videos of soft cadaver interscalene nerve block by independent, trained raters 1 week and 6 weeks after training 8. Health economic time, cost and manpower implications for training specialists to proficiency benchmarks; and cost of provision of nationwide simulator training against reduced complications is measured at the end of clinical testing	—
