Nurse advice line coverage in the Oklahoma City Area.
The Oklahoma City Area covers Oklahoma, Kansas, and parts of Texas. TULQ provides 24/7 telephone nurse triage for the IHS service units, 638 tribal health programs, and Urban Indian Organizations that serve it.
The Oklahoma City Area serves the largest AI/AN service population of any IHS Area, across dozens of nations. Many of the largest tribal health systems in the country operate here under self-governance compacts, procuring independently and at meaningful scale.
Facilities and programs in this Area
The Oklahoma City Area includes IHS-operated service units alongside tribally operated 638 programs and compacts. Illustrative facilities:
- W.W. Hastings Hospital, Tahlequah
- Claremore Indian Hospital
- Lawton Indian Hospital
- Large tribally operated health systems statewide
This is not a complete list. The Indian Health Service maintains the authoritative directory of Area facilities and service units, and tribally operated programs change hands between IHS and tribal operation over time.
What coverage looks like here
The service is the same everywhere: one number, answered any hour by a U.S. state-licensed registered nurse working Schmitt-Thompson telephone triage protocols, with the encounter documented and returned to the facility. What changes by Area is the context around it, how far the nearest emergency department is, what the winter looks like, whether the caller has reliable cellular service, and how the program is funded.
For IHS-operated service units, after-hours coverage is typically procured through the Area office and appears publicly on SAM.gov. For 638 programs and compacts, it is procured directly by the tribe or tribal organization, with no IHS solicitation required. Both paths are covered on our tribal health page.
