Association Between Socioeconomic Status and Asthma-Related Emergency Department Visits Among World Trade Center Rescue and Recovery Workers and Survi

The authors sought to examine the relationship between barriers to care (in this case, race, education, and income) and asthma-related emergency department visits among responders and survivors of the 9/11 World Trade Center bombing. Of the 448 subjects who had at least one ED visit during the study period, 28% (p < .001). The authors highlight other associations and suggest there may be additional variables (e.g., lower health literacy and gaps in asthma-specific knowledge) at play.
