The effect of the Cornwall and Isles of Scilly helicopter ambulance unit on the ambulance services' ability to deliver acutely traumatized patients to hospital.
OBJECTIVE
to determine whether the use of a helicopter ambulance unit enabled an ambulance service to deliver acutely traumatized patients to hospital more quickly.


METHODS
retrospectively collected ambulance service and hospital records data analysed longitudinally.


METHODS
The ambulance service and the major casualty department in Cornwall.


METHODS
the provision of a helicopter ambulance unit to a county ambulance service.


METHODS
patients with compound lower limb fractures carried as emergencies by an ambulance service. Principle outcome measure: ambulance 'mission times'.


RESULTS
the ambulance services' ability to deliver emergency patients to hospital more quickly when the helicopter unit was available was not demonstrated. In some instances availability of the helicopter unit probably delayed the timely delivery of emergency patients to the casualty department.


CONCLUSIONS
until a more effective helicopter deployment strategy is in operation it is unlikely that mission time savings will occur.
