项目摘要

Project Summary/ Abstract A growing share of Medicare beneficiaries are enrolled in Medicare Advantage (MA) rather than traditional fee- for-service (TM) Medicare, with the MA share increasing from 13% in 2004 to 39% in 2020. The Centers for Medicare and Medicaid Services (CMS) pay MA plans a monthly capitated rate to cover nearly all health care expenses for plan enrollees. MA plans keep as profits the portion of payments that are not used to cover enrollee expenses. In addition, CMS grants MA plans greater freedom to manage enrollees’ health care use, for example, through tools such as narrow provider networks and broader coverage of delivery innovations such as telemedicine. Proponents argue that these financial incentives and effective tools for MA plans might enable them to provide care more efficiently than TM. On the other hand, these effects could be offset by financial incentives under capitation to limit service provision beyond what is necessary to improve short term health, resulting in adverse impacts on longer-term outcomes. Prior work has primarily estimated cross-sectional comparisons of TM and MA enrollees, which could lead to biased estimates if MA enrollees differ from TM enrollees in other ways that are related to health care use and health outcomes. Our proposed project will study changes in MA enrollment coming from seven states that recently changed public retiree health benefits from supplemental TM coverage to mandatory MA plans (or in one state, from a mandatory MA plan to supplemental TM coverage). We will use these natural experiments, along with comprehensive Medicare data for TM and MA enrollees, to estimate the causal impact of MA enrollment on health care use, quality, and patient outcomes. These results will provide important evidence to policymakers weighing broader expansions of Medicare Advantage.

项目概要/摘要越来越多的 Medicare 受益人加入 Medicare Advantage (MA)，而不是传统的收费计划。服务 (TM) 医疗保险，MA 份额从 2004 年的 13% 增加到 2020 年的 39%。医疗保险和医疗补助服务 (CMS) 支付 MA 计划每月按人头付费，以涵盖几乎所有医疗保健计划参与者的费用。 MA 计划将未用于覆盖参保者的付款部分保留为利润开支。此外，CMS 赋予 MA 计划更大的自由来管理参保者的医疗保健使用，例如，通过狭窄的提供商网络和更广泛的交付创新覆盖范围等工具远程医疗。支持者认为，这些财政激励措施和 MA 计划的有效工具可能使他们比 TM 更有效地提供护理。另一方面，这些影响可能会被财务方面所抵消。按人头付费的激励措施，将提供的服务限制在改善短期健康所需的范围之外，从而对长期结果产生不利影响。先前的工作主要估计了横截面 TM 和 MA 注册者的比较，如果 MA 注册者与 TM 不同，可能会导致估计偏差参与者以与医疗保健使用和健康结果相关的其他方式。我们提出的项目将研究七个州的 MA 入学率发生了变化，这些州最近改变了公共退休人员的健康福利强制性 MA 计划的补充 TM 保险（或在一个州，从强制性 MA 计划到补充 TM 覆盖范围）。我们将使用这些自然实验以及 TM 和 MA 的综合医疗保险数据参与者，以估计 MA 注册对医疗保健使用、质量和患者结果的因果影响。这些结果将为决策者权衡扩大医疗保险范围提供重要证据优势。
