The study involved semi-structured interviews with two cohorts of participants: the first cohort were individuals who had been involved in pre-hospital trials (both trauma and non-trauma) in either a strategic or operational capacity (across different roles) within the UK — referred to herein as ‘The second cohort were individuals involved in the recruitment and intervention delivery to the P-PRO studyIn the P-PRO Study, London HEMS teams are tasked with deploying Zone 1 P-REBOA in patients in the pre-hospital setting. The balloon is positioned above the level of suspected haemorrhage and inflated to augment aortic blood pressure above the balloon whilst reducing bleeding below. Once the haemodynamics have stabilised, the balloon is partially deflated to allow some controlled distal blood flow (P-REBOA) and therefore oxygen delivery, to mitigate against the ischaemia that is otherwise created. P-PRO clinical investigators then transport patients to the nearest Major Trauma Centre, whilst managing the balloon in situ.Interviews with the P-PRO clinical investigators were narrower in focus with specific behaviours of interest to be investigated (recruitment and intervention delivery in a future trial). As such data collection and analysis was informed by the Theoretical Domains Framework (TDF). The TDF is an established behavioural framework that integrates 33 theories of behaviour into 14 domains that inhibit or enable behaviour (knowledge, skills; social/professional role and identity; beliefs about capabilities; beliefs about consequences; optimism; reinforcement; intentions; goals; memory/attention/decision processes; environmental context and resources; social influences; emotion; behavioural regulation) [
