Overarching aim The aim was to improve delivery of prehospital cardiovascular care through collaboration with frontline clinicians, by ensuring all patients presenting with a heart attack (i.e. Acute Myocardial Infarction (AMI)) or stroke receive critical-to-quality care.
Objectives  Our objectives were to improve the delivery of care bundles for AMI to at least 70% and more than 90% for stroke by April 2012.
Methods
  • We aimed to improve reliability of pre-hospital care processes for these conditions 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 and the QIC provided an environment to share successful strategies within and across services to improve care bundles for AMI and stroke.
  • We analysed change over time using logistic regression to measure the effect of the national QIC on delivery of pre-hospital care bundles for AMI and stroke.
  • We undertook a questionnaire survey investigating the use of QI methods and its relationship with leadership behaviour and culture.
  • We conducted a multiple case study to understand how and why change occurred in those services where care bundles improved.
Outcomes 
  • ASCQI members were significantly more likely to use QI methods.  The intended aim of the QIC was to educate staff in the use of such methods, but overall uptake of QI methods was low.
  • The use of QI methods was also significantly associated with leadership behaviour and service tenure.
  • Overall performance for the care bundle for AMI increased nationally in England from 43 to 79 percent and for stroke from 83 to 96 percent.
  • Implementing care bundles as part of a national QIC led to significant improvements care for AMI and stroke provided by English ambulance services.

Impact  Our work has contributed to improving the delivery of critical-to-quality pre-hospital care nationwide.Nationally, the delivery of the AMI care bundle increased from 43% to 79% (ranging from 54.5% to 100% across trusts) and for stroke, delivery has increased from 83% to 96% (range 92% to 100%). To illustrate the benefits, 1,065 more AMI patients are now being given aspirin. The ‘International Study of Infarct Survival’ (ISIS-2) found patients who received aspirin within the first five hours of onset of cardiac chest pain had a 13% reduced risk of mortality, compared to those who were given aspirin between 5-12 hours after onset. We estimate an additional 138 patients’ lives per year are being saved following the improvements achieved through ASCQI by just increasing the administration of aspirin.We calculated 4,266 more stroke patients are having their blood glucose levels assessed by ambulance clinicians before arrival at hospital. Through ASCQI we have successfully created an environment which facilitates on-going shared learning and cross-fertilisation of ideas between ambulance trusts. QI methodologies have been received enthusiastically by frontline clinicians. The introduction to, and sustained usage of, QI tools and SPC charts have proved effective in identifying gaps, developing solutions and measuring effects.Their usage has spread to improve other areas of clinical care, such as asthma, hypoglycaemia and cardiac arrest. Similar methods are now being applied to improve other areas such as reducing on-scene times and usage of e-PRFs.
