PHOTON Activity

Active studies


National Institute of Clinical Excellence (NICE) major trauma guidelines state that pre-hospital emergency anaesthesia (PHEA), if indicated, should be performed within 45 minutes of the emergency call for major trauma patients. The Pre-Hospital Trainee Operated Research Network (PHOTON) will retrospectively audit all HEMS services in the UK for time of call, dispatch, arrival and PHEA, comparing performance against the NICE recommendation. The data will be used to anonymously identify examples of excellent practice and areas for service improvement that can be used to improve the quality of care delivered to our major trauma patients nationally.

PHOTON ongoing research

Since the creation of the PHOTON pre-hospital care collaborative research group in November 2017 the group has gone from strength to strength. There are now over 40 members and representation from every Air Ambulance organisation in the country. The first two studies have collected all their data, with all 21 UK Air Ambulance organisations contributing and are undergoing final statistical analysis with an aim to publish this summer. Time to PHEA looks at the time between 999 call and delivery of emergency anaesthesia to trauma patients and Where are we now is a study of what pre-hospital critical care interventions are delivered where in the UK and at what times. Meanwhile PHOTON members are finalising protocols and ethical approval for the next two studies; Elderly Trauma will look at what critical care interventions are delivered to the elderly by pre-hospital critical care teams and HEMS Dispatch will establish the current state of HEMS dispatch nationwide aiming to guide further research into this key area.
