    Ambulance Service Cardiovascular Quality Initiative (ASCQI) 2009-12
    Funded by the Health Foundation: Closing the Gap in Clinical Communities Award, awarding £475,000. Key contact: Professor Niro Siriwardena
    The aim of ASCQI was to improve delivery of pre-hospital cardiovascular care through collaboration with frontline clinicians. All patients presenting with Acute Myocardial Infarction (AMI or heart attack) or stroke were to receive critical-to-quality care. The objectives were to increase the delivery to at least 70 per cent of AMI patients and more than 90 per cent of stroke patients by April 2012 using a Quality Improvement Collaborative (QIC). The QIC involved educating ambulance staff in Quality Improvement (QI) methods, and the use of plan-do-study-act cycles (PDSA) to implement changes. Ambulance staff were provided with feedback on the effect of the PDSA cycles using control charts and the QIC provided an environment to share successful strategies within and across services to improve care bundles for AMI and stroke. The delivery of the AMI care bundle has increased from 43% to 79% of patients nationally. For stroke, the delivery of the care bundle has increased from 83% to 96% of patients nationally. The main results were published in a highly accessed paper in Implementation Science: Siriwardena AN, Shaw D, Essam N, Togher F, Davy Z, Spaight A, Dewey M. The effect of the Ambulance Services Cardiovascular Quality Initiative on prehospital care for acute myocardial infarction and stroke in England. Implementation Science 2014; 9:17. doi:10.1186/1748-5908-9-17.


     

    Improving Prehospital Ambulance Care and Treatment following the Ambulance Services Cardiovascular Quality Initiative (ImPACT-ASCQI) 2014-15
    Funded by the Health Foundation: Spreading Improvement Award, awarding £29,572. Key contact:  Professor Niro Siriwardena
    The aim of ImPACT-ASCQI  is to widen the impact of the Ambulance Services Cardiovascular Quality Initiative (ASCQI) by providing a sustainable and long-term increase in quality improvement (QI) knowledge and skills to a wider proportion of ambulance staff ((including front-line staff, managers, executives) and to extend this further to other healthcare (medical, nursing and allied health) staff. We will achieve this aim by applying the learning from ASCQI through a variety of educational activities (including local workshops, webinars, E-learning and an electronic toolkit), disseminating knowledge from both ASCQI and ImPACT-ASCQI to a range of key stakeholders, opinion leaders and decision-makers in order to continue to improve outcomes for patients with a broader range of emergency and non-emergency conditions.


     

    The ‘Rapid Intervention with Glyceryl Trinitrate in Hypertensive Stroke Trial’ (RIGHT) 2010-13
    Funded by Nottingham University Hospital Charity, awarding £9,038. Key contact: Professor Niro Siriwardena
    This study had two main aims: to assess the feasibility of using ambulance service practitioners to assess and deliver treatments for stroke in the ultra-acute setting after stroke; and to assess the effect of GTN use in ultra-acute stroke on safety, clinical, functional, and haemo-dynamic outcomes. Its objectives included: reporting the proportion of randomised patients with a final diagnosis of ischaemic stroke, primary intra-cerebral haemorrhage, or transient ischaemic attack; and assessing the proportion of patients randomised and treated according to protocol.  Comparison of systolic blood pressure at two hours post randomisation between GTN and no GTN groups was chosen as a primary outcome since it represented the sum of the trial feasibility and intervention. The RIGHT trial is the world’s first completed ambulance-based, randomised, controlled stroke trial and has tested using GTN patches within four hours of a stroke by recruiting and treating 41 patients in the ambulance. The results of the RIGHT trial were published in Stroke: Ankolekar S, Fuller M, Cross I, Renton C, Cox P, Sprigg N, Siriwardena AN, Bath P. Feasibility of an ambulance-based trial, and safety of glyceryl trinitrate, in patients with ultra-acute stroke: the ‘Rapid Intervention with Glyceryl trinitrate in Hypertensive stroke Trial’ (RIGHT, ISRCTN66434824). Stroke 2013; 44(11): 3120-3128. doi: 10.1161/STROKEAHA.113.001301. An accompanying paper was published in the Annals of Emergency Medicine: Ankolekar S, Parry R, Sprigg N, Siriwardena AN, Bath PMW. Views of paramedics on their role in an out-of-hospital ambulance-based trial in ultra-acute stroke: qualitative data from the Rapid Intervention with Glyceryl Trinitrate in Hypertensive Stroke Trial (RIGHT).

    Interview Study of Patients and Practitioners for Developing PROVE (IS-PROVE) 2009-12
    Funded by the Health Foundation, awarding £475,000 as part of ASCQI. Key contact: Fiona Togher
    Patient Reported Outcome Measures (PROMs) and Patient Reported Experience Measures (PREMs) are questionnaires designed to measure outcomes and experience of care that are important to patients. Their routine use is becoming increasingly important in the evaluation of health care services. The purpose of this study was to undertake the preliminary work which would inform development of a PROM and PREM for patients presenting with stroke or heart attack in the pre-hospital setting that could be routinely used by ambulance clinicians to improve the quality of care provided in the pre-hospital setting. The results were published in the EMJ: Togher F, Davy Z, Siriwardena AN. Patients’ experiences and outcomes for prehospital care of acute myocardial infarction and stroke: qualitative study of patients and ambulance clinicians. Emergency Medical Journal 2013;30(11):942-8. doi: 10.1136/emermed-2012-201507.


     

    Decision-Making and Safety in Emergency Care Transitions 2010-13
    Funded by the National Institute for Health Research, Service Delivery and Organisation (NIHR SDO), awarding £168,690. Key contact: Professor Niro Siriwardena
    This study aims to identify areas of high-risk regarding decision-making about service user options. It has three objectives: to map the emergency care system in a sample of ambulance services; to investigate the factors influencing decision-making by ambulance service staff; and to feedback study findings to participating ambulance services and stakeholders. The study uses a range of qualitative methods to explore influences on safe decision-making during key emergency care transitions. These include: interviews with key members of ambulance service staff; ethnographic methods involving operational ambulance service staff; and focus groups with operational ambulance service staff and service users. It is expected that the findings of the study will be directly relevant to emergency care services in identifying potential influences on decision-making and the delivery of safe care.
