Anaesthesia Non-Technical Skills: can anaesthetists be trained to reliably use this behavioural marker system in 1 day?

Anaesthetists could not be trained to reliably use ANTS as a summative assessment tool using our 1 day programme. There was an inadequate correlation of scores between participants and experts. Two major problems contributed to the lack of agreement. Observed behaviours were often misclassified into the incorrect element and safety beliefs varied among anaesthetists. Other reasons for the failure to achieve success and potential future direction are discussed.
