Bushfire smoke (PM2.5) and asthma hospitalisations in Australia WA 2015-2017
A population-based study in WA analysing hospital admissions in Perth in 2015-2017 and smoke exposure using a model tracking PM2.5 levels during 1700 bushfires and burn offs found that following exposure to high PM2.5 (12.60 mcg/m3 or higher) there was:
– 16% (RR 1.16, 95% CI 1.00 to 1.35) increase in hospital admissions on the same day as exposure
– 93% increase in asthma hospitalisations the next day (lag of 1 day) for children
– 52% increase in asthma hospitalisations on a lag of 3 days in low socio-economic groups.
