Research Background and Aims Patient experience is considered an integral part of high-quality healthcare. The paramedic profession is developing rapidly and understanding how and what patients experience during a paramedic intervention is an essential part of further development of practice. Patient experience of paramedic interventions during a perceived emergency has not previously been described in research. The aim of this research is to explore patients' experience of paramedic interventions and understand published key performance indicators (KPI) considering that experience. Little is known about the patient's perspective of their experience and most research considers satisfaction, or the fulfilment of expectations, synonymous with experience. Despite the limited interpretation, previous research has demonstrated that patients are satisfied with paramedic care and that assistance in negotiating complex care assists in maintaining satisfaction. Furthermore, previous research indicates that clarity and certainty are sought by most patients during an interaction. By utilising a holistic, case study approach, this research provides insight into patient experience of paramedic interventions in southern England in a manner that no other research to date has achieved. This understanding of patient experience is important to the development of the profession as it strives for new and unique contributions to health and emergency care. [...]
