Study type
Interventional
Description of intervention(s) / exposure
In this non-drug trial, we will perform psychometric testing on junior doctors recruited into the study. The testing is paper based and is a battery of norm based, standardised neuro-cognitive tests of innate visuospatial and psychomotor ability and administered by a trained neuropsychologist. Tests include the Mental Rotations A, Block Design, Matrix Reasoning, Zig-Zag, and Trail Making Tests A and B. All tests will take 45-60minutes.
Participants will then be stratified into low ability cohorts (defined as > 1 standard deviation below population mean). The low ability cohort will receive mental imagery training, which is a textually and graphically rich written script with step by step descriptions of the fibreoptic bronchoscopy procedure. Participants will be asked to read through and mentally rehearse each of the steps for 1 week. Training is via a paper booklet sent to participants. Each participant will be asked to perform mental imagery training daily for the 1 week, and should take approximately 15 minutes per rehearsal. Compliance will be audited by researchers at the end of the training week. This week of training will occur 3 weeks after psychometric baseline assessment; ie. 1 week prior to bronchoscopy testing.
All participants will then be asked to perform a fibreoptic bronchoscopy procedure on an anatomically correct bench top manikin. This performance will be timed and a video recorded of the performance for scoring by blinded experts using a validated global rating scale

Efficacy
Statistical methods / analysis
Based on individual scores in the psychometric tests, participants will be stratified by population norms into ‘low’ and ‘high’ ability cohorts. Sample size is based on population norms of psychometric tests used, which are normally distributed. We expect 12-15 participants in each low and high ability cohorts. No formal power calculation has been performed.
The time taken to successfully complete the task, and Global rating scale numerical scores, will be analysed against cohort by t tests or the Mann-Whitney U tests. Dichotomous satisfactory and unsatisfactory performance item in the global rating scale will be analysed against cohort by Fisher's exact test. Rate of improvement from baseline to 1-month performance for each cohort will be analysed by repeated measures ANOVA. Correlation between psychometric scores, time taken to complete the task, and GRS scores, will be analysed by Pearson or Spearman rank correlation. A two tailed, P value < 0.05 will be deemed significant.

Summary
Brief summary
Flexible video fibreoptic bronchoscopy (FOB) is an important component of the airway skills required by doctors in the area of critical care, including anaesthetists, intensive care physicians, and in emergency medicine. Speed and accuracy of performance, as well as causing no trauma to the patient's airway, is essential to secure the airway for adequate oxygenation and ventilation. However, FOB skills are often learnt in an unstructured format by trainees, and clinical exposure is limited by their relative rarity, causing skills decay after initial training.
In this study, we are examining if training in FOB skills can be improved based on the innate visuospatial and psychomotor abilities of doctors. Other procedural tasks in medicine, similar in complexity to FOB, have previously been shown to be associated with these cognitive abilities as they influence hand-eye dexterity and motor skills.
An educational intervention will be provided to those novices identified with lower visuospatial and psychomotor abilities, to determine if these novices can be brought up to the same level of FOB performance as their higher ability colleagues. This training is based on mental rehearsal of the procedure, which has been used by professional athletes, musicians, and by surgeons where they "practice" the performance in their heads before they actually perform it in real life.
This study will recruit doctors rotating into critical care areas where FOB skill is necessary (anaesthesia, intensive care, emergency medicine). Visuospatial and psychomotor ability will be assessed by a standardised test battery. For doctors stratified into the low ability cohort of visuospatial and psychomotor ability, mental imagery training will be provided. FOB performance is measured using an anatomically correct, benchtop manikin of the human airway. Primary endpoint of performance is time taken to successfully perform a FOB task, and secondary endpoint is proficiency as evaluated by blinded assessors using a validated global rating scale.
