The Indian Health Service is an agency of the Department of Health and Human Services responsible for health care for about 2.8 million American Indians and Alaska Natives who are members of 574 federally recognized tribes. In parts of Alaska, Arizona, New Mexico, Montana, the Dakotas and Oklahoma it is the health system, not one option within it.
Nurses are the largest clinical group in it, and the terms of employment differ enough from ordinary hospital work to be worth setting out.
Three kinds of facility
The system is usually described by three letters, for the three sorts of organization that run its facilities.
Federal. Hospitals and clinics operated directly by the Indian Health Service, staffed by federal employees, either civil service or officers of the Public Health Service Commissioned Corps.
Tribal. Facilities that a tribe has taken over and now runs itself, using federal funds transferred under the self-determination and self-governance laws that began in 1975. The staff are tribal employees, not federal ones, and the tribe sets pay and conditions. Most of the system now works this way; the Alaska Native Tribal Health Consortium and the health systems of the Cherokee, Chickasaw and Choctaw Nations are large examples.
Urban. Programs serving American Indian and Alaska Native people living in cities, which is where the majority of the population now lives.
The distinction matters to a nurse taking a job. Two hospitals a hundred miles apart may look identical and have entirely different employers, benefits, pay scales and hiring processes.
Licensing is different at a federal facility
A nurse working at a federally operated facility may hold a current, unrestricted license from any state. It does not have to be the state the facility sits in.
That rule comes from federal employment rather than from the state, and it is why a nurse licensed in Ohio can work at a federal facility in Arizona without applying to the Arizona board. It applies to Indian Health Service hospitals, Veterans Affairs facilities and military treatment facilities alike, and it does not apply to tribally operated facilities, which generally require a license in the state where they are.
The same principle covers advanced practice. Practice authority at a federal facility follows federal policy, so a nurse practitioner may work to the full extent of their training at a federal site inside a state that would otherwise require a physician agreement. See nurse practitioner practice authority.
The work
Facilities range from hospitals with surgical and obstetric services to clinics with a handful of exam rooms, and many are a long way from anything larger. Nursing there is generalist work with long transfers, described under rural and frontier nursing and critical access hospitals.
The clinical picture is distinctive. Diabetes and its complications, chronic kidney disease, injury and behavioral health carry far more weight than in the general population, and the service's diabetes program has been one of the more successful public health efforts in the country. Public health nursing and community outreach are a larger part of the job than in most hospital systems.
The service also runs its own loan repayment program, which pays down qualifying student debt for a two year service commitment and is extendable. For a new graduate carrying nursing school debt it is among the more substantial repayment options available anywhere.
Vacancies
The system's persistent problem is that it cannot fill its posts. Federal oversight reporting has documented nursing vacancy rates across Indian Health Service facilities running far above what hospitals elsewhere consider a crisis, sustained over years rather than as a spike.
The causes are the ones that affect any remote hospital, compounded by funding. The service is discretionary spending appropriated annually rather than an entitlement like Medicare, so per person spending has run well below other federally funded health programs, and pay has not kept pace with the travel and staffing agency rates that facilities then have to pay to cover the gaps. See the nursing shortage.
