The presence of a large uninsured population may create incentives to providers that affect the care delivered to all individuals in a health care market. Using Current Population Survey data on uninsurance rates and hospital discharge data on Medicare beneficiaries, this study investigates the relationship between the uninsurance rate at the metropolitan statistical area (MSA) level and inpatient quality of care delivered to Medicare beneficiaries, as measured by mortality from eight procedures and conditions. The results do not indicate large or widespread negative effects of the uninsured on Medicare beneficiaries. However, some evidence suggests that the relationship between the local uninsurance rate and Medicare mortality does vary by market size.
大量未参保人群的存在可能会给医疗服务提供者带来影响，进而影响医疗保健市场中所有个体所接受的治疗。本研究利用当前人口调查中关于未参保率的数据以及医疗保险受益人的医院出院数据，调查了大都市统计区（MSA）层面的未参保率与医疗保险受益人所接受的住院治疗质量之间的关系，住院治疗质量通过八项手术和病症的死亡率来衡量。结果并未表明未参保人群对医疗保险受益人有重大或广泛的负面影响。然而，一些证据表明，当地未参保率与医疗保险死亡率之间的关系确实会因市场规模而异。
