Recent expansions in health insurance coverage have raised concerns about health care providers' capacity to supply additional services and how that may have affected access to care for people who were already insured. When we examined data for the period 2008-14 from the Medical Expenditure Panel Survey, we found no consistent evidence that increases in the proportions of adults with insurance at the local-area level affected access to care for adults residing in the same areas who already had, and continued to have, insurance. This lack of an apparent relationship held true across eight measures of access, which included receipt of preventive care. It also held true among two adult subpopulations that may have been at greater risk for compromised access: people residing in health care professional shortage areas and Medicaid beneficiaries.
最近医疗保险覆盖范围的扩大引起了人们对医疗服务提供者提供额外服务的能力的担忧，以及这可能如何影响已经参保的人获得医疗服务的问题。当我们研究 2008-14 年期间来自医疗支出调查的数据分析时，我们没有发现任何一致的证据表明，当地成年人保险比例的增加会影响居住在同一地区并已参保且继续参保的成年人获得医疗服务的机会。这种没有明显关系的情况在八项获得医疗服务的衡量标准中都是成立的，其中包括接受预防保健的情况。在两个可能面临更严重获得服务机会受损风险的成年人亚群中，这种情况也是成立的：居住在医疗保健专业人员短缺地区的人和医疗补助受益人。
