The NAACCR Hispanic Identification Algorithm (NHIA) uses a combination of NAACCR 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 NAACCR standard variables: Spanish/Hispanic Origin [190], Name-Last [2230], Name-Maiden [2390], Birthplace [250], Race 1 [160], and Sex [220]. Code 7 (Spanish surname only) of the Spanish/Hispanic Origin [190] data item became effective with 1994 diagnosis. It is recommended that NHIA should be run on 1995 and forward diagnosis. However, a central registry may run it on their data for prior years. 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. The registries often have significant numbers or proportions of Hispanic populations in their jurisdiction. .. NAACCR Data Standards and Data Dictionary Version 11
