Queensland's 24 hour health hotline is receiving over 450 calls every day, according to new government figures on the service.

There have been 320,000 calls for medical advice since the hotline began operating two years ago.

Since February 2006, 20,873 callers have been referred to the ambulance service and over 56,000 have been told to go to their local hospital emergency department.

Others were advised to see their GP - 49,000 within an hour and 38,586 within the next day.

Fever toddler and abdominal pains in adults are the two most common medical symptoms reported by callers.

Releasing the numbers from the first two years of the hotline, health minister Stephen Robertson said it was an invaluable service to many.

“One caller sought advice earlier this year on what she thought was a mosquito bite,” he said.

“On (the hotline's) advice she visited her doctor who diagnosed a white tail spider bite - she was put on antibiotics."

“One caller thought he was suffering indigestion, but thankfully the 13 HEALTH nurse called an ambulance because it was actually a heart attack."

The hotline had a rocky start in 2006 after a child died despite his parent contacting the service.

Rachelle Coggins, 22, contacted the hotline in December after her son developed a 38-degree temperature.

She said the nurse told her he did not need to go to hospital because it was probably an ear infection.

Baby Alexander was later found dead in his cot.
