Introduction: In the United States, smoking is the leading cause of death-having a mortality rate of approximately 435,000 people in 2000-accounting for 8.1% of all US deaths recorded that year. Methods: This study aimed to analyze the Delaware Hospital Discharge Database and identify state and non-state residents discharged with AMI or asthma for the years 1999 to 2004. Statistical data analysis compared the incidence of AMI or asthma for each group before (1999-2002) and after (2003-2004) the comprehensive amendment of the The Delaware Clean Indoor Air Act of 1994. Results: Pre-ordinance and post-ordinance quarterly rates of AMI for Delaware residents were 451 (se = 21) and 430 (se = 21) respectively, representing a 4.7% reduction. Over the same time period, there was negligible change in the incidence of AMI for non-Delaware residents. After adjusting for population growth, the Risk Ratio (RR) for asthma in Delaware residents post-ordinance was 0.95 (95% CI, 0.90 to 0.999), which represented a significant reduction (p = 0.046). By comparison, non-Delaware residents had an increased RR for asthma post-ordinance of 1.62 (95% CI, 1.46 to 1.86; p < 0.0001). Conclusion: Delaware's comprehensive non-smoking ordinance effectively was associated with a statistically significant decrease in the incidence of AMI and asthma in Delaware residents when compared to non-Delaware residents.

Conclusion: Delaware’s comprehensive non-smoking ordinance effectively was associated with a statistically significant decrease in the incidence of AMI and asthma in Delaware residents when compared to non-Delaware residents. Learning Objectives: 1. Determine the impact of the 2002 Delaware smoking ordinance on heart attack and asthma rate; and 2.Compare the difference between pre-ordinance and post-ordinance quarterly rates on heart attack and asthma.
