Hospitalisations with a principal diagnosis of chest pain (ICD-10-AM codes R07.1, R07.3, and R07.4) were analysed.
Analyses did not identify a consistent pattern in relation to impacts from bushfires and chest pain hospitalisations.
Nationally, there were increases in the hospitalisation rate for chest pain across most weeks during the 2019–20 bushfire season, particularly in the early season from mid-September to the end of October 2019.

Admitted patient hospitalisation rate, by jurisdiction, chest pain (ICD-10-AM codes R07.1, R07.3, R07.4), weeks in 2019–20 bushfire season relative to previous 5-year average
This combined chart shows the crude rate of admitted patient hospitalisations (per 100,000 persons) for chest pain for the periods 2019–20 and the previous 5-year average, and the percentage change in crude rate between the two periods. Data are presented by jurisdiction and by week, for the period 1 September to 29 February/1 March, which correspond to the bushfire season. The chart shows that nationally, there were increases in the hospitalisation rate across most weeks during the 2019–20 bushfire season, particularly in the early season from mid-September to the end of October 2019. There were also variations at the jurisdictional level.
At the state and territory level, there were no consistent patterns between chest pain hospitalisations coinciding with periods of significant fire activity or air pollution. That is, New South Wales demonstrated lower chest pain hospitalisations each week during the 2019–20 bushfire season, compared with the average of the previous 5-year period, while Victoria and Queensland demonstrated higher chest pain hospitalisations each week during the same period.
Similarly, no consistent relationship between air quality from bushfires and chest pain hospitalisations was observed at the level of Statistical Area Level 4 (SA4).
