      Background Cardiovascular disease (CVD) affects 1.8% of the population annually, 0.9% with stroke and 0.8% with coronary heart disease. People suffering from CVD often present acutely to ambulance services with symptoms of acute myocardial infarction or stroke. Early and effective treatment prevents death, improves long term health and reduces future disability. Objective Our aim is to develop a rational approach for informing the design and evaluation of a national project for improving prehospital care of myocardial infarction and stroke: the Ambulance Services Cardiovascular Quality Initiative (ASCQI), the first national improvement project for prehospital care. Methods We will use a case study methodology initially utilising an evaluation logic model to define inputs (in terms of resources for planning, implementation and evaluation), outputs (in terms of intended changes in healthcare processes) and longer-term outcomes (in terms of health and wider benefits or harms), whether intended or incidental and in the short, medium or long term. Results We will present an evaluation logic model for the project. This will be expanded to show the analytical techniques which we will use to explain how and why the project achieves its outcomes. This includes times series analyses, pattern matching, cross case syntheses and explanation building to inform an explanatory logic model. We will discuss how this model will be useful in determining the data that will need to be collected during the course of the project to inform the detailed explanation of how and why the project delivered its outcomes. Conclusion The case study approach will enable us to evaluate the impact of this collaborative project in constituent ambulance services as well as the initiative as a whole. It will enable us to show whether and to what extent the project has had an impact, but also how and why this has happened. https://emj.bmj.com/content/emermed/28/11/e2.7.full.pdf This is an Open Access article distributed in accordance with the Creative Commons Attribution Non Commercial (CC BY-NC 4.0) license, which permits others to distribute, remix, adapt, build upon this work non-commercially, and license their derivative works on different terms, provided the original work is properly cited and the use is non-commercial.

    • Patients' and ambulance service clinicians' experiences of prehospital care for acute myocardial infarction and stroke: a qualitative study

      Togher, Fiona Jayne; Davy, Zowie; Siriwardena, Aloysius (2013-11)
      BACKGROUND: Patients with suspected acute myocardial infarction (AMI) and stroke commonly present first to the ambulance service. Little is known about experiences of prehospital care which are important for measuring the quality of services for patients with AMI or stroke. AIM: We explored experiences of patients, who had accessed the ambulance service for AMI or stroke, and clinicians regularly treating patients for these conditions in the prehospital setting. METHOD: A qualitative research design was employed to obtain rich and detailed data to explore and compare participants' experiences of emergency prehospital care for AMI and stroke. RESULTS: We conducted 33 semistructured interviews with service users and clinicians and one focus group with five clinicians. Four main themes emerged: communication, professionalism, treatment of condition and the transition from home to hospital. Patients focused on both personal and technical skills. Technical knowledge and relational skills together contributed to a perception of professionalism in ambulancepersonnel. Patients' experience was enhanced when physical, emotional and social needs were attended to and they emphasised effective communication within the clinician-patient relationship to be the key. However, we found a discrepancy between paramedics' perceptions of patients' expectations and patients' lack of knowledge of the paramedic role. CONCLUSIONS: Factors that contribute to better patient experience are not necessarily understood in the same way by patients and clinicians. Our findings can contribute to the development of patient experience measures for prehospital care. https://emj.bmj.com/content/emermed/30/11/942.full.pdf This is an Open Access article distributed in accordance with the Creative Commons Attribution Non Commercial (CC BY-NC 4.0) license, which permits others to distribute, remix, adapt, build upon this work non-commercially, and license their derivative works on different terms, provided the original work is properly cited and the use is non-commercial.
