Kirby K, et al. - EMS experiences of engaging in a large trial of airway management during out-of-hospital cardiac arrest (AIRWAYS-2) were examined, particularly to determine: the changes in views and practice as a result of trial participation; experiences of trial training; experiences of recruiting critically unwell patients without consent; barriers and facilitators for out-of-hospital trial participation. Researchers administered an online questionnaire to 1,523 EMS providers who engaged in the trial and conducted in-depth telephone interviews for the responses to the online questionnaire. Thirty-three percent of the EMS providers responded, and 19 providers were interviewed. The experience of participation was reported as enjoyable and the study training and support were described as valuable by EMS providers. Participation in the trial led to an enhancement in the confidence in airway management. As stated by EMS providers, training, experience, and confidence in tracheal intubation are variable and the method of airway management to which they had been randomized is preferable. The stepwise approach to airway management is supported in this work, however, there is also concern about the possible loss of tracheal intubation from ‘standard’ EMS practice.
