Burn epidemiology in the Brisbane and Queensland area.

Aim: The aim was to evaluate changes in patterns of injury and whether mortality rates have decreased.

Method: The database over 20 years from 1982 to 2002 and the 6 years 1997 to 2003 was studied.

Results: 4523 admissions. 73.7% males, 26.3% females. Monthly and seasonal admissions showed little fluctuation. 52.8% in the 21-40 years age group, 19.7% under 20 years, 19.4% in the 41-60 years group and 8.1% over 60 years. TBSA: 80.4% under 20%, 12.6-21% to 40%, 3.3-41% to 60% and 3.4% were over 61%. Causes: flame 56%, scalds 26%, contact 9%, chemical 5%, electrical 2%, friction 1% flash burns 1%. Fifty five percent at home, 20% work, 13% motor vehicles and 11% leisure. Fifteen percent had significant inhalation injuries and 81% required intubation. Mortality rate for 6 years was 2.1%. In 1972-1996 of 4096 burns was 3.6% and 3.4% in 1993-1996.

Conclusion: Little change in patterns of injury. Burns less than 20% predominate. The majority were under 40 years. Inhalation injury, large burns and elderly were major causes of morbidity and mortality. Mortality rate is falling.
