Description
The NAACCR Hispanic Identification Algorithm (NHIA) uses a combination of standard variables to directly or indirectly classify cases as Hispanic for analytic purposes. It is possible to separate Hispanic ancestral subgroups (e.g., Mexican) when indirect assignment results from birthplace information but not from surname match. The algorithm uses the following standard variables: Spanish/Hispanic Origin [190], Name--Last [2230], Name--Maiden [2390], Birthplace [250], Race 1 [160], IHS Link [192], and Sex [220].

Code 7 (Spanish surname only) of the Spanish/Hispanic Origin [190] data item became effective with 1994 diagnoses. It is recommended that NHIA should be run on 1995 and later diagnoses. However, a central registry may run it on their data for prior years. For greater detail, please refer to the technical documentation: http://www.naaccr.org/dat#NHIA.

Rationale
Sometimes despite best efforts to obtain complete information directly from the medical record, information is not available and is reported to the cancer registry as a missing data item. With regard to Hispanic ethnicity, some cancer registries have found it necessary to rely on indirect methods to populate this data element. Registries often have significant numbers or proportions of Hispanic populations in their jurisdiction.
