Not Native American, but I wanted to note that the IHS has led the way for many of the roles pharmacists play today!
"Indian Health Service (IHS) pharmacists practice in a true pharmaceutical care environment where they fully utilize their knowledge and skills. IHS has pioneered many progressive and innovative advances over the past thirty years. Pharmacists have access to the patient's entire health record including laboratory results, immunization status, and past medical history to assess the appropriateness of drug therapy. Problems are resolved with providers prior to dispensing medications, and all patients are counseled on their medication therapy. In many locations, pharmacists are credentialed to provide primary care and use their prescriptive authority to evaluate and manage the care of certain patients." Also the first to use consultation rooms in the pharmacy.
Learned about it in my healthcare delivery class last semester!
