“…Perkins (1993) suggests that a Spanish surname match is less efficient in areas with low concentrations of Hispanics. However, in this study we found consistent improvement of accuracy in identifying Hispanics using the combined Medicare race code and Spanish surname indicator across areas that vary widely in the concentration of Hispanics for both men and women (Figures 1 and 2), as also shown previously among men (Morgan, Wei, and Virnig 2004). Nevertheless, it is undetermined if our results can be generalized to areas outside of our sampling frame, particularly those areas with extremely low concentrations of Hispanics.…”

“…Further, Hispanics often choose to identify with a country of personal or ancestral origin rather than the general classification of ''Hispanic.'' For example, in our studies, when Hispanics have chosen a response of ''other'' for their race/ethnicity, it has not been unusual for them to write in a designation such as ''Venezuelan'' or ''white Cuban American'' (Morgan, Wei, and Virnig 2004).…”

“…Their study found sensitivities of 85 and 87 percent from male respondents for the census list and GUESS methods, respectively, and slightly lower sensitivities of 79 and 82 percent from female respondents. A more recent publication reported the results of two studies assessing the accuracy of surname matching using the 1990 Census Spanish Surname list for identifying elderly Hispanic males in both regional and national Medicare data (Morgan, Wei, and Virnig 2004). Comparing with self-identified race/ethnicity collected from 1,530 male veterans aged 65 or older, the Spanish surname match augmented Medicare race code substantially improved the identification of Hispanic males.…”

“…However, prior works have documented that Hispanics are substantially underrepresented in Medicare data (Arday et al 2000;Morgan, Wei, and Virnig 2004;Waldo 2004). In brief, the underrepresentation stemmed from the fact that the race code contained in the Medicare Enrollment Database is obtained from the Social Security Administration Master Beneficiary Record (SSA-MBR), which is collected from the SSA application form (SS-5) (Lauderdale and Goldberg 1996).…”

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 5 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 code1Spanish 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 code1Spanish 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.

“…The Generally Useful Ethnic Search System, or GUESS, is a previously validated surname program for identifying Hispanic subpopulations in the southwest [8][9][10][11][12]. The GUESS program was revised and validated using state tumor registry records by the Lovelace Clinic Foundation in Albuquerque, New Mexico [6].…”

This study examines the variation in surname analysis and geocoding, and their association with self-identified Hispanics in an HMO. We collected ethnicity data from three studies, and employed Spanish surname software and census tract level geocoding to create proxies for Hispanic ethnicity. We computed sensitivity, specificity, and estimated multivariate logistic regression models to examine the variation in the likelihood of a match between self-identified Hispanics and surname. Sensitivity and specificity with respect to surname varied across the three studies, ranging from 57%-91% and 89%-96%, respectively. Relative to self-report, the sensitivity of the census tract measure of density of Hispanics, varied from 5%-15%. Multivariate models suggest that the likelihood of a match between self-identified Hispanics and surname was not associated with age or gender. Self-identified Hispanics living in neighborhoods with the highest density of Hispanics were less likely than those in more mixed neighborhoods to have a Spanish surname. Employing the Spanish surname software on only densely populated Hispanic census tracts may not always improve the likelihood of correctly identifying Hispanic subjects.

Medicare is a federal health insurance program for nearly all Americans aged 65 and over, for younger persons entitled to Social Security disability payments for at least 2 years, and for people with end‐stage renal disease (ESRD) or amyotrophic lateral sclerosis (ALS). It is administered by the Centers for Medicare and Medicaid Services (CMS) in the US Department of Health and Human Services. In 2016, persons with entitlement due to these mandates numbered over 48 million, 8.8 million, and 525 000, respectively. Medicare, especially the program's extensive repository of enrollment and administrative claims information, are a unique resource for health services research, owing to the program's size, national representativeness, continuity of enrollment, presence of race and date‐of‐death data, well‐documented history of use in research, and the help available for researchers wishing to use the data for studies of potential benefit to Medicare beneficiaries.
