Objective:
The main objective of the Norwegian air ambulance
service is to provide advanced emergency medicine to critically ill
or severely injured patients. The government has defined a time
frame of 45 minutes as the goal within which 90% of the popula-
tion should be reached. The aims of this study were to document
accurate flying times for rotor wing units to the scene and to
determine the rates of acute primary missions in Norway.
Methods:
We analyzed operational data from every acute primary
mission from all air ambulance bases in Norway in 2011, focusing
on the flying time taken to reach scene, the municipality request-
ing the flight, and the severity score data.
Results:
A total of 5,805 acute primary missions were completed
in Norway in 2011. The median flying time was 19 minutes (25%-
75% percentiles: 13-28). The mean mission rate for the 17 bases
was 7.5 (95% confidence interval, 7.4-7.8 per 10,000 inhabitants).
The overall mean (standard deviation) National Committee on
Aeronautics score for all missions was 4.07 (1.30).
Conclusion:
The government’s expectation of serving the entire
population via HEMS within 45 minutes appears to be achieved on
a national level. However, vast differences remain in the flying
times and rates between bases.
