STRICT identification procedures will ensure the teenager caught impersonating doctors at Adelaide's hospitals does not come in direct contact with patients.

SA Health chief executive David Swan told The Advertiser yesterday he was very confident the teen had been identified and removed every time he had entered a hospital ward dressed as a doctor.

As revealed on adelaidenow on Thursday, the 17-year-old teen has been seen in Royal Adelaide Hospital wards, wearing a name badge and stethoscope, and even reading patient notes, on three occasions since October.

There have been numerous sightings of the teen on the grounds of Flinders Medical Centre wearing scrubs, an FMC lanyard and stethoscope. He has also been seen in the city posing as a doctor/clinician and offering first aid to the general public.

Mr Swan said the teen had been swiftly identified and removed from hospital premises on each occasion he had entered an RAH ward.

Mr Swan said: "What we've done is issue our staff with a photograph of the individual, we've heightened security in relation to being aware of this individual and reinforced with our staff the policies and protocols with regards to identification."

While police have spoken to the teen he has not actually committed an offence.
