  • Effects of the Beijing tobacco control policy on AMI and stroke hospital admissions

  • The MPOWER tobacco control policy package has been implemented in Beijing since June 2015. In an interrupted time series study, researchers sought to assess the impact of the policy on hospital admissions for acute myocardial infarction (AMI) and stroke. The population comprised 31,707 AMI and 128,116 stroke hospital admissions recorded by the Beijing Medical Claim Data for Employees in 17.7 million residents from January 2013 to June 2017.

    Results showed that there was a secular increase trend for the crude hospital admission rates of AMI and stroke during the observational period. After implementation of the policy, immediate reductions were observed in the hospital admissions for both AMI (-5.4%; 95% confidence interval [CI], -10.0% to -0.5%) and stroke (-5.6%; 95% CI, -7.8% to -3.3%), as well as a -15.3% slowdown in the secular increase trend for stroke (95% CI, -16.7% to -13.9%) annually. It was determined that during the 25-month post-policy period, an estimated 18,137 (26.7%) stroke hospital admissions had been prevented, compared with the hypothetical scenario where the policy had not taken place.

    In summary, the results indicated significant health benefits on cardiovascular morbidity after the Beijing tobacco control policy package, and further underlines the importance for a comprehensive tobacco control policy at the national level in China. The researchers added that to maximize public health gains, a similar tobacco control policy consisting of all components of MPOWER, is especially necessary in settings with high tobacco consumption.
