The document discusses a presentation made to the National EMS Scope of Practice Model task force regarding EMS models in the United States from a Western perspective. It notes that many current EMS systems do not fully align with the vision outlined by NHTSA for a more community-based, public health approach. It suggests the Scope of Practice Model should support this vision through competencies that facilitate EMS integration into healthcare systems and address chronic illness, injury prevention, and public health needs.
