Simulation-Based Bronchoscopy Training (publication featuring Dexter® highlighted favourably in 2013 Mayo Clinic meta-analysis)
‘Inductive analysis to inform instructional design suggested that longer or more structured training is more effective, authentic clinical context adds value, and animal models and plastic part-task models may be superior to more costly virtual reality simulators.’

Duration of distributed practice required by novices to achieve proficiency (96% within 4 hrs of practice) was demonstrated in a study published in the British Journal of Anesthesia in 2010.

Bronchoscopic performance in the medium term reflects the level of skill achieved at initial training rather than the frequency of subsequent exposure to the technique. Abstract presented at Difficult Airway Society Meeting Cardiff 2012.

Bronchoscopy Training Effectiveness
Dexter was more effective than another part-task trainer with trainees preferring it and practicing for longer. Clinical endoscopic effectiveness by novice endoscopists after Dexter training with 93% transference of bench proficiency to the clinical environment on first clinical attempt was published in Anesthesia and Analgesia in 2004

Improvement of bronchoscopy skills after training with Dexter was published in the Canadian Journal of Anesthesia in 2005.
