DESCRIPTION (provided by applicant): Over one-half of incident breast cancers occur among Medicare-enrolled women, and Medicare enrollees receive approximately one-third of all screening mammograms nationwide (~13 million annual mammograms). Thus, improving the quality of screening mammography received by Medicare enrollees remains a public health priority. In 2001, Congress extended Medicare coverage to digital mammography and the application of computer-aided detection (CAD) during screening mammography. Rigorous evaluation of the clinical and economic impact of dissemination these technologies within the Medicare population have substantial policy significance. Although Medicare claims could be fruitful data source for such evaluations, uncertainty remains about the validity of key data elements. The Program Announcement, "Cancer Surveillance Using Health Claims-based Data System," calls for research to expand the scientific utility of Medicare claims files. In response, this study will use the newly linked Breast Cancer Surveillance Consortium (BCSC)-Medicare data to validate critical data elements of Medicare mammography claims and to evaluate the performance of claims-based algorithms for distinguishing screening from diagnostic mammograms and normal from abnormal radiologist interpretations. Specific aims are: 1) To refine and validate a promising claims-based algorithm to distinguish screening from diagnostic mammograms. 2) To externally validate claims procedure codes for digital mammography and computer-aided detection (CAD). 3) To develop and validate a claims-based algorithm to distinguish whether screening mammograms were interpreted as normal vs. abnormal. Analyses will demonstrate the potential utility of the claims algorithms for comparative effectiveness research or radiologist-level quality assessment in the context of mammography technology diffusion. PUBLIC HEALTH RELEVANCE: This study may provide essential methodological support for subsequent claims-based comparative effectiveness, economic, quality improvement research related to mammography. By elucidating the strengths and weaknesses of the claims data, study findings may also direct programmatic efforts to improve the quality of Medicare claims data.

描述（由申请人提供）：超过一半的乳腺癌事件发生在参加医疗保险的妇女中，医疗保险参加者接受全国约三分之一的筛查乳房X光检查（每年约1300万次乳房X光检查）。因此，提高医疗保险参保者接受的筛查性乳房X光检查的质量仍然是公共卫生的优先事项。2001年，国会将医疗保险的覆盖范围扩大到数字乳房X光检查和计算机辅助检测（CAD）在筛查乳房X光检查期间的应用。严格评估这些技术在医疗保险人群中传播的临床和经济影响具有重大的政策意义。虽然医疗保险索赔可能是这种评估的富有成效的数据来源，但关键数据元素的有效性仍然存在不确定性。 该计划公告，“癌症监测使用健康索赔为基础的数据系统，”呼吁研究，以扩大医疗保险索赔文件的科学效用。作为回应，本研究将使用新链接的乳腺癌监测联盟（BCSC）-医疗保险数据来验证医疗保险乳房X光检查索赔的关键数据元素，并评估基于索赔的算法的性能，以区分筛查和诊断乳房X光检查以及正常和异常放射科医生的解释。具体目标是：1）完善和验证一个有前途的基于索赔的算法，以区分筛查和诊断性乳房X线照片。 2)外部验证数字乳腺X射线摄影和计算机辅助检测（CAD）的索赔程序代码。 3)开发并验证一种基于声明的算法，以区分筛查乳房X线照片是否被解释为正常与异常。 分析将证明索赔算法在乳腺X射线摄影技术扩散背景下用于比较有效性研究或放射科医师水平质量评估的潜在效用。 公共卫生关系：本研究可为后续基于索赔的乳腺X线摄影相关的比较有效性、经济性、质量改进研究提供必要的方法学支持。通过阐明索赔数据的优点和缺点，研究结果也可以指导计划工作，以提高医疗保险索赔数据的质量。
