项目摘要

DESCRIPTION (provided by applicant): The Effect of Health Insurance on Utilization and Outcomes: The Oregon Lottery. Understanding the consequences of health insurance coverage is central to evaluating proposals to expand or modify health insurance coverage in the U.S. It also has important long-run fiscal implications for Medicare. Yet there is remarkably little convincing evidence on the effect of insuring the uninsured on health care utilization, health outcomes, and overall well-being, because it is difficult to disentangle the effects of health insurance from other factors that differ between the insured and uninsured that also affect health. A remarkable opportunity has presented itself for providing just such evidence. For a limited window in early 2008, Oregon opened a waiting list for enrollment in its previously closed public health insurance program for certain low income adults, and then randomly drew names from the list to determine who would be given the opportunity to enroll. This unique policy environment provides researchers with a rare occasion to bring the strengths of random assignment - the standard in medical trials - to address a critical social policy question. We have already begun surveying those selected and not selected in the lottery, and propose to use NIA funding to greatly extend the reach of our data collection and analysis, including over-sampling of the near-elderly (those aged 50-64) whose health risks are in many ways similar to those aged 65 and up and who will soon age onto Medicare themselves. We propose to capitalize on this extraordinary and unique opportunity to address questions in three different areas: First, how does insurance affect health care utilization? Second, what are the effects of insurance on health? Third, how do the effects of health insurance differ for different groups? We will answer these questions by drawing on three data sources: semi-annual mail surveys, an in-person data collection effort including measurement of physiological markers of health, and administrative records on hospital and emergency department use. PUBLIC HEALTH RELEVANCE: Understanding the consequences of gaining access to health insurance is central to evaluating proposals to expand or modify health insurance coverage in the U.S. The proposed research will take advantage of a unique health insurance lottery currently underway in Oregon to evaluate the causal effects of insurance on health care utilization and health outcomes. The project will powerfully leverage existing resources to allow us to explore the effects of insurance expansions for those groups of particular policy importance.

描述（由申请人提供）：健康保险对使用和结果的影响：俄勒冈州彩票。了解医疗保险覆盖范围的后果是评估扩大或修改美国医疗保险覆盖范围的建议的核心，它也对医疗保险具有重要的长期财政影响。然而，很少有令人信服的证据表明，为未投保的人投保对医疗保健利用率、健康结果和整体幸福感的影响，因为很难将医疗保险的影响与其他因素分开，这些因素在投保人和未投保人之间也会影响健康。提供这种证据的绝佳机会已经出现。在2008年初的一个有限的窗口，俄勒冈州为某些低收入成年人开放了一个先前关闭的公共医疗保险计划的等候名单，然后从名单中随机抽取名字，以确定谁将有机会参加。这种独特的政策环境为研究人员提供了一个难得的机会，使随机分配的优势-在医学试验中的标准-来解决一个关键的社会政策问题。我们已经开始调查那些在彩票中被选中和未被选中的人，并建议使用NIA资金来大大扩展我们的数据收集和分析范围，包括对近老年人（50-64岁）的过度抽样，他们的健康风险在许多方面与65岁及以上的人相似，他们很快就会进入医疗保险。我们建议利用这一非凡而独特的机会，解决三个不同领域的问题：第一，保险如何影响医疗保健利用？二、保险对健康有哪些影响？第三，健康保险对不同群体的影响有何不同？我们将通过利用三个数据源来回答这些问题：每半年一次的邮件调查、面对面的数据收集工作（包括健康生理标志物的测量）以及医院和急诊室使用的行政记录。公共卫生相关性：了解获得医疗保险的后果是中央评估建议，以扩大或修改医疗保险覆盖范围在美国拟议的研究将利用一个独特的健康保险彩票目前正在进行中的俄勒冈州，以评估医疗保健利用和健康结果的保险的因果关系。该项目将有力地利用现有资源，使我们能够探讨保险扩张对那些具有特殊政策重要性的群体的影响。
