Staff availability and team dynamics influence recruitment and intervention delivery (TDF environmental context and resources; social influences)
RECRUITMENT
Participants described the challenges of working in a pre-hospital setting with reference to the lack of available staff with the required technical skills to support trial recruitment and intervention delivery during some shifts. Staff rotation schedules also meant that staff would be unlikely to work with the same team during each shift (also raising issues related to trial training) and team dynamics impacted on study delivery in terms of communication and managing roles. Some participants emphasised that trials evaluating pre-hospital REBOA may require additional personnel to facilitate randomisation. A lack of staff available to support pre-hospital activities and recruitment could potentially limit the conduct of a trial in this setting.… I think three or four [staff members] is a really nice number because there’s quite a lot going on, and I suppose some of it may be equally the HEMS team delivering the procedure … what’s the number to facilitate the randomisation of the patient group, is it two or is it three, because at some point to randomise you’re going to have to… facilitate the randomisation.
