"Minnesota Medicaid enrollee files matched to self-report information from a telephone/mail survey of 4,902 enrollees conducted in 2003. Measures of agreement between the two measures of race/ethnicity are computed. Using logistic regression, we also assess whether misclassification of race/ethnicity on administrative files is associated with demographic factors, health status, health care utilization, or ratings of quality of health care. Race/ethnicity fields from administrative Medicaid files were extracted and merged with self-report data. The administrative data correctly classified 94 percent of cases on race/ethnicity. Persons who self-identified as Hispanic and those whose home language was English had the greater odds (compared with persons who self-identified as white and those whose home language was not English) of being misclassified in administrative data. Persons classified as unknown/other on administrative data were more likely to self-identify as white. In this case study in Minnesota, researchers can be reasonably confident that the racial designations on Medicaid administrative data comport with how enrollees self-identify. Moreover, misclassification is not associated with common measures of health status, utilization, and ratings of quality of care," wrote D.D. Mcalpine and colleagues, University of Minnesota.

The researchers concluded: "Further replication is recommended given variation in how race information is collected and coded by Medicaid agencies in different states."

Mcalpine and colleagues published their study in Health Services Research (Agreement between self-reported and administrative race and ethnicity data among Medicaid enrollees in Minnesota. Health Services Research, 2007;42(6 Part 2):2373-2388).
