LOINC description : 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.
