Introduction: Victims of out-of-hospital cardiac arrests require timely cardiopulmonary

randomisation and the funding of prehospital critical care for OHCA. Method We aimed to answer the following questions: What are stakeholders' priorities for prehospital research? What are stakeholders' views on randomisation of prehospital critical care? How do stakeholders consider allocation of resources in prehospital care? We undertook a qualitative framework analysis of interviews and focus group with five key stakeholder groups: patients and public, air ambulance charities, ambulance service commissioners, prehospital researchers and prehospital critical care providers. Results Despite sharing a common appreciation of the concepts of scientific enquiry, fairness, and beneficence, the five relevant stakeholder groups displayed divergent views of research and funding strategies regarding the intervention of prehospital critical care for the condition of OHCA. The reasons for this divergence could largely be explained through the different personal experiences and situational contexts of each stakeholder group. Many aspects of the strategies suggested by the stakeholder groups only partially aligned with principles of traditional evidence-based medicine, but were held with strong conviction. Conclusion Analysis of the views of five stakeholder groups regarding research and the funding of prehospital critical care for OHCA revealed shared values, but a variety of different strategies to achieve these. This knowledge can help researchers in similar fields in the planning and presentation of their research, to maximise impact on decision making.
