Description
This variable captures the results of the linkage of the registry database with the Indian Health Service patient registration database.
Rationale
The IHS linkage identifies cancer cases among American Indians who were misclassified as non-Indian in the registry database in order to improve the quality of cancer surveillance data on American Indians in individual registries and in all registries as a whole. The goal is to include cancer incidence data for American Indians in the United States Cancer Statistics by use of this variable as well as the race variable.
