The objective of this survey was to investigate the incidence of respiratory symptoms reported by emergency department patients during the Christmas 2001–2002 Sydney bushfire disaster. Two hundred and thirty patients attending two Sydney emergency departments for any reason completed questionnaires regarding respiratory symptoms. The symptoms investigated were cough, shortness of breath, chest tightness and wheeze. The same questionnaire was subsequently administered to a similar control group who were not exposed to bushfire smoke. 51% of those surveyed during the bushfires reported one or more of the respiratory symptoms investigated compared to 31% of the control group. This difference was statistically significant (p < 0.01). A significantly higher proportion of respiratory patients in the study group reported an exacerbation of their condition and increased medication use during the bushfires (p < 0.01). The results are consistent with other research on the subject and suggest that exposure to bushfire smoke causes an increased incidence of respiratory pathology.
