背景：医疗补助是美国低收入个人的主要公共健康保险计划。一些州的医疗补助计划包括预防性眼科护理服务和视力矫正，而另一些则只包括紧急眼科护理。与其他可选福利类似，各州可能会随着时间的推移增加或减少成人视力福利。研究目的：本文探讨提供成人视力福利是否与视力检查期间测得的适当矫正远视力的低收入人群比例增加相关。方法：我们使用2001年至2010年的检查数据，估计医疗补助视力覆盖范围对适当矫正远视力的可能性的影响。2008年全国健康与营养检查调查。我们比较视力的医疗补助受益人（n = 712）和其他低收入的成年人没有参加医疗补助（n = 4786）之前和之后的变化，以国家视力coverage policy.Findings：29和33个国家之间提供医疗补助成人视力福利在2001年至2008年，取决于一年。我们的研究结果意味着，医疗补助成人视力覆盖范围与医疗补助受益人的百分比显着增加，适当纠正远视力高达10个百分点。结论：提供视力覆盖到医疗补助的成年人显着增加适当纠正远视力的可能性。关于视力覆盖对相关功能结果的影响以及医疗补助覆盖对其他服务的影响的进一步研究可能是适当的。(C)2015爱思唯尔有限公司版权所有。
Background: Medicaid is the main public health insurance program for individuals with low income in the United States. Some state Medicaid programs cover preventive eye care services and vision correction, while others cover emergency eye care only. Similar to other optional benefits, states may add and drop adult vision benefits over time.Research objective: This article examines whether providing adult vision benefits is associated with an increase in the percentage of low-income individuals with appropriately corrected distance vision as measured during an eye exam.Methodology: We estimate the effect of Medicaid vision coverage on the likelihood of having appropriately corrected distance vision using examination data from the 2001-2008 National Health and Nutrition Examination Survey. We compare vision outcomes for Medicaid beneficiaries (n = 712) and other low income adults not enrolled in Medicaid (n = 4786) before and after changes to state vision coverage policies.Findings: Between 29 and 33 states provided Medicaid adult vision benefits during 2001-2008, depending on the year. Our findings imply that Medicaid adult vision coverage is associated with a significant increase in the percentage of Medicaid beneficiaries with appropriately corrected distance vision of up to 10 percentage points.Conclusion: Providing vision coverage to adults on Medicaid significantly increases the likelihood of appropriate correction of distance vision. Further research on the impact of vision coverage on related functional outcomes and the effects of Medicaid coverage of other services may be appropriate. (C) 2015 Elsevier Ltd. All rights reserved.
