Number Data variable name Type of data Data variable categories or values
Choose only one option unless otherwise stated.
Definition of data variable
33 Established airway management procedure (SOP) Ordinal 1 = Yes, SOP with Checklist
2 = Yes, SOP only
3 = No SOP
SOP including algorithm for difficult intubation (expected/unexpected) available in EMS service.
34 Type of airway currency training in service Nominal 1 = Clinical rotation with regular airway management practise (e.g. anaesthesia)
2 = Regular airway management currency assessments (e.g. RSI simulation)
3 = Regular mannequin training
4 = Regular cadaver training
5 = Other, describe
Clinical rotation: describes system with regular airway management currency (e.g. anaesthesia practise).
Regular airway management currency assessment (e.g. RSI simulation) describes systems with simulation or virtual training for airway management currency.
Cadaver and mannequin describes systems with regular airway management skill training.
Select all that apply.
