The document discusses different methods for querying patients about their race and ethnicity in a respectful and effective way. It tested various question orderings and response options at a hospital. Asking about Hispanic ethnicity first and then race with OMB categories worked best for US-born patients and Hispanic patients. An open-ended question about ethnicity worked better for foreign-born non-Hispanic patients. The document proposes a two-question method asking first how others perceive the patient's race and second how they self-identify.
