Brief Summary

The adverse effects of sleep related fatigue are significant, impacting on doctors' health, wellbeing, performance and ultimately their safety and that of their patients'. Trainees are at an increased risk of fatigue because they routinely, and are increasingly, working long hours, and exposed to excessive and high intensity workloads. With increasing numbers of patient consultations, there is a higher risk of making poorer quality clinical decisions (i.e. decision fatigue). The excessive workloads experienced by doctors can cause fatigue through the requirement for sustained attention over long periods of time, particularly when performing complex and mentally demanding tasks. Our main objective is to study the difference between the fatigued and non-fatigued state of anaesthetists and on their ability to perform an ultrasound-guided peripheral nerve blockade task. We hypothesise that fatigue will result in a clinically significant reduction in the objective structured assessment scores of anaesthetists who are performing an ultrasound-guided peripheral nerve blockade task compared to their scores when they are non-fatigued.

Outcome Measures

Primary Outcomes (1)

  • composite error scoring within a regional anaesthesia performance task

    establish a comparison of mean composite error scores (CES) between participants in group F (fatigued state) and Group A (non-fatigued state) when performing a standardised ultrasound guided regional anaesthesia task. CES can range from 0 to 100. the higher the score the more negative the performance of the candidate.

    6 months

Secondary Outcomes (4)

  • Global rating score (GRS)

    6 months

  • Task completion time

    6 months

  • Reliability of the composite error score (CES) and global rating scale (GRS)

    6 months

  • Eye tracking metrics

Study Arms (2)

Fatigue Group

EXPERIMENTAL

The trial will recruit trainee anaesthetists of ST3 grade or higher who take part in a resident night-shift rota at Nottingham University Hospitals NHS Trust. Participants will undergo baseline psychometric testing to measure baseline mood. There will be a series of questions to ascertain levels of fatigue. All participants will then be asked to perform a standardised ultrasound-guided peripheral nerve blockade task using a high fidelity bench-top phantom model. Performance in this task will be independently assessed using a previously-validated scoring tool by two raters blinded to participant group allocation.

Behavioral: Fatigue

Non Fatigued group

ACTIVE COMPARATOR

The non fatigued group will be asked to perform the same series of questions and tasks after a night at home with no work duties or commitments

Behavioral: Fatigue

Interventions

FatigueBEHAVIORAL

The intervention will be assessing the participant in a fatigued state compared to a non fatigued state

Fatigue GroupNon Fatigued group
