Introduction

The purpose of this study is to estimate healthcare utilization and healthcare costs due to secondhand smoke exposure at home for children in the U.S.

Methods

Using data from the 2000, 2005, and 2010 U.S. National Health Interview Surveys, the authors analyzed the association between secondhand smoke exposure at home and utilization of three types of healthcare services (hospital nights, emergency room visits, and doctor visits) for children aged 3–14 years (N=16,860). A zero-inflated Poisson regression model was used to control for sociodemographic characteristics and the number of months without health insurance. The authors determined excess healthcare utilization attributable to secondhand smoke exposure at home for children and then estimated annual secondhand smoke–attributable healthcare costs as the product of annual excess healthcare utilization and unit costs obtained from the 2014 Medical Expenditures Panel Survey. This study was conducted from 2016 to 2018.

Results

The prevalence of secondhand smoke exposure at home for children in 2000, 2005, and 2010 was 25.0%, 12.3%, and 9.1%, respectively. Secondhand smoke exposure at home was positively associated with emergency room visits, but was not significantly associated with nights at the hospital or doctor visits for children. Secondhand smoke exposure at home for children resulted in an excess of 347,156 emergency room visits in 2000, 124,412 visits in 2005, and 101,570 visits in 2010, which amounted to $215.1 million, $77.1 million, and $62.9 million in excess annual healthcare costs (2014 dollars) in 2000, 2005, and 2010, respectively.

Conclusions

Although U.S. healthcare costs attributable to secondhand smoke exposure at home for children are declining, interventions to reduce secondhand smoke exposure at home for children are still needed to reduce the economic burden attributable to secondhand smoke exposure.
