Design outcomes

Primary

Measure	Time frame
Observational Study of OHCA Survival: Survival to hospital discharge is measured by reviewing ambulance notes (in case of prehospital death) at the time of data submission by the attending prehospital provider, or through review of hospital notes of receiving hospitals (in case of survival to hospital admission) at 3 months. Cost Analysis: Cost of prehospital care (advanced life support and critical care) in pound sterling. Costs will be measured through review of ambulance and charity financial records. Qualitative Work On Research Attitudes: Themes of views about prehosptial research are assessed using information collected at focus groups.	—
