BACKGROUND: Millions of people can potentially be exposed to smoke from forest
fires, making this an important public health problem in many countries.
OBJECTIVE: In this study we aimed to measure the association between
out-of-hospital cardiac arrest (OHCA) and forest fire smoke exposures in a large
city during a severe forest fire season, and estimate the number of excess OHCAs
due to the fire smoke. METHODS: We investigated the association between
particulate matter (PM) and other air pollutants and OHCA using a case-crossover
study of adults (? 35 years of age) in Melbourne, Australia. Conditional logistic
regression models were used to derive estimates of the percent change in the rate
of OHCA associated with an interquartile range (IQR) increase in exposure. From
July 2006 through June 2007, OHCA data were collected from the Victorian
Ambulance Cardiac Arrest Registry. Hourly air pollution concentrations and
meteorological data were obtained from a central monitoring site. RESULTS: There
were 2,046 OHCAs with presumed cardiac etiology during our study period. Among
men during the fire season, greater increases in OHCA were observed with IQR
increases in the 48-hr lagged PM with diameter ? 2.5 ?m (PM2.5) (8.05%; 95% CI:
2.30, 14.13%; IQR = 6.1 ?g/m(3)) or ? 10 ?m (PM10) (11.1%; 95% CI: 1.55, 21.48%;
IQR = 13.7 ?g/m(3)) and carbon monoxide (35.7%; 95% CI: 8.98, 68.92%; IQR = 0.3
ppm). There was no significant association between the rate of OHCA and air
pollutants among women. One hundred seventy-four "fire-hours" (i.e., hours in
which Melbourne's air quality was affected by forest fire smoke) were identified
during 12 days of the 2006/2007 fire season, and 23.9 (95% CI: 3.1, 40.2) excess
OHCAs were estimated to occur due to elevations in PM2.5 during these fire-hours.
CONCLUSIONS: This study found an association between exposure to forest fire
smoke and an increase in the rate of OHCA. These findings have implications for
public health messages to raise community awareness and for planning of emergency
services during forest fire seasons.
