Medicaid enrollment varies considerably among states. This study examined the association of Medicaid enrollment with the use of substance health services in the longitudinal National Epidemiologic Survey on Alcohol and Related Conditions of 2001-2005. Instrumental variable methods were used to assess endogeneity of individual-level Medicaid enrollment using state-level data as instruments. Compared to the uninsured, Medicaid covered adults were more likely to use substance use disorder treatment services over the next three years. States that have opted to expand Medicaid enrollment under the Affordable Care Act will likely experience further increases in the use of these service over the coming years.
医疗补助计划的参与情况在各州之间存在较大差异。本研究通过使用 2001-2005 年纵向全国酒精和相关条件流行病学调查中的州级数据作为工具变量，采用工具变量方法评估了个体层面医疗补助计划参与的内生性。与没有保险的人相比，在接下来的三年里，有医疗补助的成年人更有可能使用药物使用障碍治疗服务。在平价医疗法案下选择扩大医疗补助计划参与的州，在未来几年里，这些服务的使用可能会进一步增加。
