Mobile intensive care services in rural South Australia.

In the 12 years from 1984 to 1995, Adelaide-based mobile intensive care teams transported 4443 critically ill patients from rural areas in South Australia and adjacent States to tertiary-level hospitals in Adelaide. The SA Ambulance Service undertook communications, support staffing and deployment of transport. Average radial distances in 819 road missions were 71 km, in 808 helicopter missions 122 km, and in 2777 fixed-wing aircraft missions 398 km. The largest groups of patients were neonates (23%) and those with trauma (25%). Rural hospitals made 96% of the requests for intensive care transport; 4% came from ambulance or other emergency service crews at accident locations. Emergency surgical or operative obstetrical procedures were performed on 2.7% of patients before transport. One hundred and thirteen patients (2.5%) died during resuscitation or transport, with one death deemed to be preventable.
