Methods: EAD codes are assigned at the time of the call to emergency services using standard computer assisted algorithms. We assessed EADs coded as: breathing problems, chest pain, stroke or cerebrovascular accident (stroke), cardiac or respiratory arrest and death (arrest), and heart or defibrillator problems (other heart problems). Using a daily times series study design with a generalized linear Poisson regression model we quantified the association between EAD and daily PM2.5 from all sources (PM2.5,all) and PM2.5 primarily due to LFS (PM2.5,LFS).
Results: Increases of 10μg·m-3 in PM2.5,all were positively associated with same day EAD for breathing problems (RR=1.03, 95% CI 1.02 to 1.04), arrest (RR = 1.03, 95% CI 1.00 to 1.06), and chest pain (RR = 1.01 CI 1.00 to 1.02) but not with other outcomes. Increases of 10μg·m-3 PM2.5,LFS were also positively associated with breathing problems on the same day (RR = 1.04, 95% CI 1.02 to 1.05) and other heart problems at lag of two days (RR = 1.05, 95% CI 1.01 to 1.09).
Conclusions: Emergency dispatches for breathing problems are associated with PM2.5,all and PM2.5,LFS and provide a sensitive end point for continued research and surveillance activities investigating the impacts of daily fluctuations in ambient PM2.5.
