Primary Survey Content
NPIRS is the national data repository for IHS statistical health care data on patient registration and visit encounters occurring at either IHS facilities or contracting facilities that provide care. It collects data on members of federally recognized tribes that access IHS services.
Age, gender, Indian status.
1997 to present.
National IHS service area estimates (including Aberdeen, Alaska, Albuquerque, Bemidji, Billings, Nashville, Navajo, Oklahoma, Phoenix, Tucson, excluding Portland and California service areas).
Since no IHS inpatient facilities are located in either the Portland or California Areas, hospitalizations from these regions are not present in the data; the denominator was correspondingly reduced.
