On January 11, 2009, a comprehensive smoking ban was implemented in Taiwan. The aim of this study was to evaluate the effect of this ban on hospital admissions for ischemic heart disease (IHD). Trends in the country-level monthly hospital admission rates for IHD were determined and frequency compared to other conditions such as control conditions cholecystitis, bowel obstruction, and appendicitis from January 1997 (1 year before the first phase of smoke-free laws was implemented) to December 2012 (3 years after the second phase of the ban). Poisson regression with a monthly time-series model was used to determine alterations in the trend of admission rates for IHD with comparison to rates of other disorders after the ban. Hospital admissions for IHD decreased by 0.8% (incidence rate ratio [RR]: 0.992; 95% confidence interval [CI] = 0.991-0.994) and 1.1% (incidence RR: 0.989; 95% CI = 0.988-0.991) following the first (September 19, 1997 to January 10, 2009) and second (January 11, 2009 to December 31, 2012) phases of the ban, respectively, compared with those prior to the pre-ban period, the corresponding values for the control conditions were 0.6% (95% CI = 0.5%-0.7%) and 0.7% (95% CI = 0.6%-0.9%). The admission rates significantly fell for both men and women and for all examined age categories after both first and second phases of the ban. The present findings provide evidence of a significant reduction in hospital admissions for IHD in Taiwan following smoking bans.
