Find out more about the EAAA Research, Audit, Innovation and Development (RAID) group and read our research publications below.

East Anglian Air Ambulance (EAAA) aims to provide the best possible care to our patients. Our Research Audit Innovation & Development (RAID) group supports us to monitor and continually improve the service we provide and use the latest evidence behind cutting edge pre-hospital care to develop new treatments, equipment, and skills.

We carry out original research and evaluation studies and collaborate across our network of other air ambulances, the NHS and universities to share knowledge. Our ultimate aim is to improve emergency care for all patients.

Below is a selection of recent publications by EAAA staff or using EAAA data. 

East Anglian Air Ambulance's
Pre-hospital Research Conference

On Friday 19 November East Anglian Air Ambulance held its first dedicated pre-hospital emergency medicine (PHEM) research and development conference, 'Breaking Barriers: national data sets improving collaboration and outcomes in PHEM.'

A hybrid event, sponsored by Zoll, this was the first conference held by the charity’s research, audit, innovation and development group (RAID) and focused on how collaborative working and data sharing across the sector could improve research and development opportunities and patient outcomes.

EAAA has long been interested in the benefits of clinical research to improve patient outcomes and has done a lot of service evaluation and analysis in recent years, which has led to clinicians publishing papers. When developing the EAAA 2020-2025 strategy, research and development was an important theme.

The RAID group was set up, with EAAA Dr Rob Major as Chair, to have a group of interested clinicians oversee this area, and make sure all research had value in improving the service.

The group is made up of EAAA doctors and critical care paramedics, some of whom have senior academic qualifications and appointments, and Kate Lachowycz, EAAA’s data analyst and subject matter expert.

Rob and Kate work together to refine the research strategy and how it meets the charity’s values. There are also guest members on the group for certain projects or reasons – such as the clinical director of neuro critical care at Addenbrooke’s. 

Out of hospital cardiac arrest (OHCA) - EAAA attend about 350 OHCAs a year. We're keen to investigate our data to identify things which could improve these patient's outcomes, and ultimately save more lives.

Traumatic brain injury - we’re currently looking at our data to identify how we could improve the care of patients with traumatic brain injury. This includes the care we provide at the roadside and also, in partnership with Essex and Herts Air Ambulance and the East of England Ambulance Service Trust, the recovery and aftercare of these patients.

Blood - now we’ve finished the national RePhill blood trial we are undertaking some audit work to support EAAA in developing its own system of providing blood to injured patients.

Aftercare - we’re really lucky to have such a well-developed aftercare team. We know how important their work is and are keen to do qualitative research to prove how much this helps patients and their families following an incident we attended.
