项目摘要

DESCRIPTION (provided by applicant): The Medicare Modernization Act of 2003 (MMA) mandated substantial reductions in payment rates for outpatient chemotherapy drugs. The MMA's changes, which took effect on January 1, 2005, capped the margins providers receive on oncology drugs at 6 percent above manufacturers' average (national) sales prices. At the same time, Medicare increased the fees for chemotherapy administration. This study will build on our analysis of the overall effects of the MMA on chemotherapy treatment for Medicare beneficiaries with lung and colorectal cancer. In work we recently submitted for publication, we found that doctors responded to the MMA's payment changes by providing chemotherapy treatment to a greater share of Medicare beneficiaries with lung cancer (Jacobson et al. 2009). The type of agents administered to patients also changed. Previously high margin drugs were used less commonly than prior to the payment reduction and more expensive agents were increasingly, if modestly, favored by the 6 percent margin imposed on all drugs. Our analysis of beneficiaries with colorectal cancer is ongoing, although we suspect we will find similar results. The goal of this study is to understand how the large change in payment rates for cancer drugs has affected disparities in cancer treatment. Using data on the Surveillance Epidemiology and End Results (SEER) Program linked to Medicare claims for beneficiaries diagnosed with lung and colorectal cancer between 2003 and 2006 and all associated claims for these individuals from 2002 to 2008, we plan to extend our recently completed work on lung cancer and ongoing work on colorectal cancer to understand if the MMA-related changes in treatment are concentrated disproportionately in some groups of Medicare beneficiaries rather than others and if, as a result, existing disparities widen as a result of the payment reform. The proposed study aims to analyze: Aim 1) how the MMA's changes in payment rates for cancer drugs has affected disparities in cancer chemotherapy treatment for beneficiaries with colorectal and lung cancer. Aim 2) how the MMA's changes in payment rates has affected disparities in the type of drugs administered to those patients who receive any chemotherapy treatment. Aim 3) how the MMA's changes in payment rates has affected disparities in survival for beneficiaries with colorectal and lung cancer Our proposed work would be among the very few studies of the effects of payment reforms on changes in disparities. Moreover, it would be the first, to our knowledge, that seeks to specifically understand how the MMA differentially affected chemotherapy treatment and outcomes across demographic and geographic groups. PUBLIC HEALTH RELEVANCE: The Medicare Modernization Act of 2003 (MMA) mandated substantial reductions in payment rates for outpatient chemotherapy drugs. In work recently submitted, we find that in response the MMA's payment change, Medicare beneficiaries with lung cancer are more likely to receive chemotherapy treatment and, conditional on such treatment, are more likely to receive expensive agents. The goal of the proposed study is to determine how, if at all, these changes have affected disparities in chemotherapy treatment and outcomes.

描述（由申请人提供）：2003年医疗保险现代化法案（MMA）规定大幅降低门诊化疗药物的支付率。MMA的变化于2005年1月1日生效，将供应商在肿瘤药物上获得的利润率限制在制造商平均（全国）销售价格的6%以上。与此同时，医疗保险增加了化疗管理的费用。这项研究将建立在我们对MMA对肺癌和结直肠癌医疗保险受益人化疗治疗的总体影响的分析基础上。在我们最近提交出版的工作中，我们发现医生对MMA的支付变化做出了反应，为更大比例的肺癌医疗保险受益人提供化疗治疗（Jacobson et al. 2009）。给予患者的药物类型也发生了变化。以前利润高的药物比支付减少之前使用得更少，更昂贵的药物越来越多，如果适度的话，对所有药物征收6%的利润率。我们对结直肠癌受益人的分析正在进行中，尽管我们怀疑我们会发现类似的结果。这项研究的目的是了解癌症药物支付率的巨大变化如何影响癌症治疗的差异。使用2003年至2006年期间诊断为肺癌和结直肠癌的受益人的医疗保险索赔以及2002年至2008年这些人的所有相关索赔的监测流行病学和最终结果（SEER）计划数据，我们计划扩展我们最近完成的肺癌研究和正在进行的结直肠癌研究，以了解MMA-如果支付改革导致现有的差距扩大，那么治疗方面的相关变化不成比例地集中在某些医疗保险受益人群体中，而不是其他群体。拟议的研究旨在分析：目的1）MMA对癌症药物支付率的变化如何影响结直肠癌和肺癌受益人癌症化疗治疗的差异。目标2）MMA的支付率变化如何影响接受任何化疗治疗的患者所用药物类型的差异。目标3）MMA支付率的变化如何影响结直肠癌和肺癌受益人生存的差异我们拟议的工作将是为数不多的关于支付改革对差异变化影响的研究之一。此外，据我们所知，这将是第一个试图具体了解MMA如何在人口和地理群体中差异化地影响化疗治疗和结果的研究。公共卫生相关性：2003年的医疗保险现代化法案（MMA）要求大幅降低门诊化疗药物的支付率。在最近提交的工作中，我们发现，作为对MMA支付变化的回应，患有肺癌的医疗保险受益人更有可能接受化疗治疗，并且在这种治疗的条件下，更有可能接受昂贵的药物。这项研究的目的是确定这些变化是如何影响化疗治疗和结果的差异的。
