The way emergency calls are responded to is set to be overhauled across the Isle of Man in early 2024, Manx Care has said.
Clinical navigators will assess calls to see whether patients needed an ambulance or could be treated at home.
The triaging system is currently being piloted during daytime hours in the emergency services joint control room.
Manx Care CEO Teresa Cope said the system of deploying ambulances had not changed in 30 years.
She said currently 90% of those calling 999 were taken to hospital, which was “no longer contemporary or relevant or cost effective”.
