Objective.为了评估西班牙姓氏匹配的有效性，以提高西班牙裔妇女在医疗保险管理数据中的识别，其中西班牙裔在历史上代表性不足。我们收集了自我认定的种族/民族数据（N=2,997），从邮寄的调查发送给老年医疗保险受益人谁居住在11个地理区域组成的8个大都市县和3个非大都市地区（171个县）在2004年秋季。1990年人口普查西班牙姓氏名单被用来确定医疗保险数据中的西班牙裔。此外，我们还使用了美国《金融时报》上发表的数据。S.人口普查局网站，以获得老年拉美裔人的估计。我们使用自我认定的种族/民族作为金标准来检查与医疗保险种族代码单独的协议，以及与医疗保险种族代码+西班牙姓氏匹配。此外，我们仅使用医疗保险种族代码和医疗保险种族代码+西班牙姓氏匹配，估计了调查中11个地理区域中西班牙裔女性和男性的比例，并将这些估计值与来自美国的估计值进行了比较。S. 2000年人口普查数据，主要调查结果。西班牙姓氏匹配显著提高了医疗保险种族代码识别西班牙裔和白色妇女的准确性，产生了与男性相似的改善。我们建议使用西班牙姓氏匹配在Medicare数据中添加代理种族代码，以提高种族/民族代表性的准确性。
Objective. To assess the effectiveness of a Spanish surname match for improving the identification of Hispanic women in Medicare administrative data in which Hispanics are historically underrepresented.Data Sources. We collected self-identified race/ethnicity data (N=2,997) from a mailed survey sent to elderly Medicare beneficiaries who resided in 11 geographic areas consisting of eight metropolitan counties and three nonmetropolitan areas ( 171 counties) in the fall of 2004. The 1990 Census Spanish Surname list was used to identify Hispanics in the Medicare data. In addition, we used data published on the U. S. Census Bureau website to obtain estimates of elderly Hispanics.Study Design. We used self-identified race/ethnicity as the gold standard to examine the agreement with Medicare race code alone, and with Medicare race code+Spanish surname match. Additionally, we estimated the proportions of Hispanic women and men, in each of the 11 geographic areas in our survey, using the Medicare race code alone and the Medicare race code+Spanish surname match, and compared those estimates with estimates derived from U. S. Census 2000 data.Principal Findings. The Spanish surname match dramatically increased the accuracy of the Medicare race code for identifying both Hispanic and white women, producing improvements comparable with those seen for men.Conclusions. We recommend the addition of a proxy race code in the Medicare data using the Spanish surname match to improve the accuracy of racial/ethnic representation.
