Description:

IHS Purchased/Referred Care Delivery Areas (PRCDA) consist of counties which include all or part of an American Indian/Alaska Native (AI/AN) reservation and any county or counties which have a common boundary with a reservation. This derived data item facilitates the production of the most accurate and reliable incidence rates for the AI/AN population and was previously known as IHS Contract Health Service Delivery Area (CHSDA). The PRCDA data item is derived using NAACCR*Prep based on state and county at the time of diagnosis, according to the Indian Health Service (IHS) PRCDA definition in the most recent definition in the Federal Register.

Rationale:

Data analyses restricted to areas where the IHS provides health care services improves the accuracy of cancer statistics among American Indian and Alaska Native people.
