NHTSA reassessed Montana's EMS system, fourteen years after the 1991 initial assessment. The Technical Assistance Team found the Section 'unable to address many of the 1991 recommendations' due to chronic underfunding and staffing limitations. Despite trauma enabling legislation passing in 1995, it remained inadequately funded, and no state EMS medical director, statewide protocols, functional data system, or completed statewide EMS plan existed.
Learn moreNHTSA conducted needs assessments in Nebraska and Oregon, examining EMS system capacity in states with significant rural and frontier service areas. The reports documented challenges in workforce recruitment, response times, and system funding.
NHTSA reassessments of Kansas and Michigan evaluated EMS system maturation in both a rural Great Plains state and a large industrial Midwest state, documenting progress and persistent challenges in system coordination and funding.
Colorado received a legislative EMS report and Oklahoma underwent a NHTSA reassessment, both documenting the ongoing evolution of state-level EMS systems. These assessments highlighted workforce sustainability, funding mechanisms, and the integration of EMS into broader healthcare systems.
NHTSA conducted its second reassessment of Nevada's EMS system, following the 1991 initial assessment. The report examined a state of geographic and demographic extremes, where well-resourced urban centers contrasted with rural volunteer agencies struggling to staff two EMT-Basics, and documented OEMS staffing shortfalls, declining volunteerism, and informal hospital relationships.
NHTSA reassessed Missouri's EMS system, following the 1994 initial assessment. The report highlighted the pioneering Time Critical Diagnosis System — a first-in-the-nation law authorizing regionalized systems of care for trauma, stroke, and STEMI. The Technical Assistance Team noted the system was at a crossroads, needing to shift from a local to statewide perspective as regionalization demanded cooperation across diverse communities.
NHTSA reassessed Ohio's EMS system, reviewing progress since the 2001 reassessment. The report noted that 11.5 million Ohioans depended on an EMS system that had evolved over forty years, but the lead agency lacked clear uniform regulatory authority, safety belt fine revenues were declining, and data repositories had not been fully transformed into useful policy information.
NHTSA conducted its third reassessment of Wisconsin's EMS system, following the 1990 initial assessment and 2001 reassessment. The Technical Assistance Team recognized tremendous strides over 22 years while warning that state EMS funding had decreased in absolute terms and EMS had been demoted within the governmental bureaucracy, threatening infrastructural erosion of a system built on volunteerism and community spirit.
National advisory panels met to shape the EMS Compact. Drafting teams wrote the model legislation during meetings in June, August, and October, forming the foundation for future adoption.
The Drafting Team consisted of:

NHTSA conducted reassessments of EMS systems in Connecticut and Florida. The Connecticut assessment found a system advanced in some areas yet undeveloped in others, serving 169 municipalities without county government. The Florida reassessment — initiated after discord drew national attention — found the 4th most populous state's trauma system operating as a 'loose aggregation of trauma centers with little cooperation and almost no central coordination,' with only two ambulance inspectors for over 4,000 permitted vehicles.

In 2012, the U.S. Fire Administration and FEMA released the Handbook for EMS Medical Directors. This foundational document provides guidance for physicians serving in EMS medical oversight roles, emphasizing clinical governance, protocol development, quality assurance, and the evolving role of the EMS Medical Director in modern systems.
The handbook helped professionalize and standardize expectations for physician involvement in EMS operations nationwide.

The Drafting Team consisted of:

NHTSA reassessed Alaska's EMS system, following the 1999 reassessment. The Technical Assistance Team addressed the extraordinary challenges of delivering EMS across 663,000 square miles where communities are often widely dispersed and not connected by roads, highlighting the blending of traditional Inupiat values with modern emergency medicine.
NHTSA reassessed Iowa's EMS system, examining a state with over 3 million residents, 99 counties, and 931 authorized service programs. The Technical Assistance Team documented 'near universal calls for regionalization' from presenters and found no formalized EMS or trauma regions, an outdated 1994 statewide trauma plan, and a Bureau of Emergency and Trauma Services operating on $830,000 after grants were distributed.
