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.
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.
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.
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.
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.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.

评估西班牙姓氏匹配对于改善医疗保险管理数据中西班牙裔女性识别情况的有效性，在这些数据中西班牙裔历史上代表性不足。
我们从2004年秋季寄给居住在11个地理区域（包括8个大都市县和3个非大都市地区（171个县））的老年医疗保险受益人的邮寄调查中收集了自我认定的种族/族裔数据（N = 2997）。1990年人口普查西班牙姓氏列表用于识别医疗保险数据中的西班牙裔。此外，我们使用美国人口普查局网站上公布的数据来获取老年西班牙裔的估计数。
我们将自我认定的种族/族裔作为金标准，以检验仅与医疗保险种族代码以及与医疗保险种族代码+西班牙姓氏匹配的一致性。此外，我们使用仅医疗保险种族代码和医疗保险种族代码+西班牙姓氏匹配来估计我们调查的11个地理区域中每个区域的西班牙裔女性和男性比例，并将这些估计值与2000年美国人口普查数据得出的值进行比较。
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人女性的准确性，产生的改善与男性相当。
我们建议在医疗保险数据中添加使用西班牙姓氏匹配的代理种族代码，以提高种族/族裔代表性的准确性。为了评估西班牙姓氏匹配对于改善医疗保险管理数据中西班牙裔女性识别情况的有效性，在这些数据中西班牙裔历史上代表性不足。我们从2004年秋季寄给居住在11个地理区域（包括8个大都市县和3个非大都市地区（171个县））的老年医疗保险受益人的邮寄调查中收集了自我认定的种族/族裔数据（N = 2997）。1990年人口普查西班牙姓氏列表用于识别医疗保险数据中的西班牙裔。此外，我们使用美国人口普查局网站上公布的数据来获取老年西班牙裔的估计数。我们将自我认定的种族/族裔作为金标准，以检验仅与医疗保险种族代码以及与医疗保险种族代码+西班牙姓氏匹配的一致性。此外，我们使用仅医疗保险种族代码和医疗保险种族代码+西班牙姓氏匹配来估计我们调查的11个地理区域中每个区域的西班牙裔女性和男性比例，并将这些估计值与2000年美国人口普查数据得出的值进行比较。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人女性的准确性，产生的改善与男性相当。我们建议在医疗保险数据中添加使用西班牙姓氏匹配的代理种族代码，以提高种族/族裔代表性的准确性。
