Introduction
The air ambulance system in Norway was established in 1988 and its main purpose was to provide rapid advanced medical care, assist health-care providers in the municipalities in cases of emergency, and provide expedient patient transport to definite care.
During the last decade, local emergency infrastructure has changed, often resulting in centralisation of GP (general practitioner) on-call services.
The aim of the present survey is to describe the involvement of the GP on-call in emergency medical situations attended by the air ambulance in a rural part of Norway.
