Rates of hospitalisations and mortality of older adults admitted with burn injuries in Western Australian from 1983 to 2008

Aim: To estimate temporal trends in burn injury hospitalisations, mortality and hospital stay, for older adults with a burn-related hospitalisation. Methods: De-identified data of all incident burn hospitalisations for adults 60 years and older in Western Australia from 19832008 were analysed. Poisson regression analyses were used to estimate temporal trends in hospital admissions and mortality. Zero truncated negative binomial regression analysis was used to identify factors associated with hospital stay. Results: Between 1983 and 2008, hospitalisation rates increased for scalds (incident rate ratio (IRR) 1.01, 95% CI: 1.001.02) and contact burns (IRR 1.05, 95% CI: 1.031.07) while a significant reduction in flame hospitalisation rates (IRR 0.93, 95% CI: 0.920.94) was estimated. No significant changes in length of stay or burn-related mortality were estimated. Conclusions: Burn safety and prevention strategies that include first aid education need to be developed that target older adults living in their homes, to decrease their risk of sustaining burn injuries.
