We study the effect of public insurance on smoking cessation medication prescriptions and financing. We leverage variation in insurance coverage generated by recent Affordable Care Act expansions to Medicaid. We estimate differences-in-differences models using administrative data on the universe of Medicaid-financed prescriptions sold in retail and online pharmacies 2011-2017. Our findings suggest that these expansions increased Medicaid-financed smoking cessation prescriptions by 34%. This increase reflects new medication use and a shift in payment from private insurers and self-paying patients to Medicaid. Adjusting our estimate for changes in financing implies that Medicaid expansion lead to a 24% increase in new medication use.
我们研究了公共保险对戒烟药物处方及资金筹集的影响。我们利用了近期《平价医疗法案》(Affordable Care Act)向医疗补助计划(Medicaid)扩展所产生的保险覆盖范围差异。我们使用2011年至2017年零售和网上药店销售的所有医疗补助计划资助处方的行政数据,估计了双重差分模型。我们的研究结果表明,这些扩展使医疗补助计划资助的戒烟处方增加了34%。这一增长反映了新药物的使用以及支付方从私人保险公司和自费患者向医疗补助计划的转变。对资金筹集变化进行调整后的估计表明,医疗补助计划的扩展使新药物的使用增加了24%。
