In order to best respond to an emergency situation, professionals need to have an understanding about Autism Spectrum Disorder (ASD) and techniques that will ensure proper care. The purpose of this study was to determine the knowledge and confidence of EMS personnel on interacting and treating an individual with ASD. Emergency Medical Technicians (EMT), and Paramedics were surveyed on their knowledge of ASD; familiarity or experience with ASD, and level of comfort responding to emergencies involving an individual with ASD. The results found that autism-specific training and resources were associated with higher comfort levels, but not knowledge. It was also determined that newer and younger professionals had higher knowledge and comfort when compared to the more experienced and older professionals.
