Summary: | Abstract Background During the past 3 decades, numerous cities and states have adopted laws that ban smoking in public indoor spaces. The rationale for these policies has been to protect nonsmokers from the adverse health effects of secondhand smoke. Objective To determine whether the implementation of indoor smoking legislation is associated with a decrease in emergency department visits for asthma in children. Methods This retrospective analysis used a natural experiment to estimate the impact of clean indoor air legislation on the rate of emergency department admissions for asthma exacerbation in children. Data were obtained from the Pediatric Health Information System. A Poisson regression was used for analyses and controlled for age, sex, race, payer source, seasonality, and secular trends. Results Asthma emergency department visits were captured from 20 hospitals in 14 different states plus the District of Columbia from July 2000 to January 2014 (n = 335,588). Indoor smoking legislation, pooled across all cities, was associated with a decreased rate of severe asthma exacerbation (adjusted rate ratio 0.83, 95% confidence interval 0.82–0.85, P < .0001). Conclusion Indoor tobacco legislation is associated with a decrease in emergency department visits for asthma exacerbation. Such legislation should be considered in localities that remain without this legislation to protect the respiratory health of their children. |
