Summary
This report analyzes public perceptions of Emergency Medical Services (EMS) and their relationship to motor vehicle crashes (MVCs), drawing data from the 2016 Motor Vehicle Occupant Safety Survey (MVOSS). The study is motivated by the critical role EMS plays in traffic safety; approximately one-third of all injury-related EMS responses in the United States between 2012 and 2016 were MVC-related. Furthermore, two out of five individuals killed in MVCs were alive at the scene, highlighting the potential for EMS intervention to prevent fatalities. The report aims to assess public trust, usage patterns, and willingness to fund EMS, noting that strengthening trauma systems and reducing response times could significantly lower MVC mortality rates. The methodology utilized the seventh iteration of the MVOSS, a periodic national survey administered between June 2016 and February 2017. Researchers recruited a probability-based, nationally representative sample of approximately 12,000 individuals aged 18 or older using address-based sampling across 24,000 households. The final dataset comprised 5,410 completed surveys, with 49% completed online. Respondents received financial incentives for participation. The analysis focuses on 32 questions specifically addressing EMS, with data weighted to yield national estimates. Key findings indicate that 57% of respondents had called 911 or another emergency number at least once. Among those who had made an emergency call, 54% reported their most recent call was for an ambulance or EMS. For individuals calling from a motor vehicle, 62% were reporting a crash. Public sentiment toward EMS was overwhelmingly positive: 92% considered it an essential government service, a figure rising to 94% among those who had previously called 911. Trust in EMS clinicians was exceptionally high, with 99% of respondents expressing confidence that responders would know how to handle emergencies. Additionally, 77% believed communities should fund EMS similarly to police and fire departments, and 72% were willing to pay at least $5 annually in fees or taxes to improve EMS equipment and training. The significance of these findings lies in the stark contrast between public perception and current policy. While the majority view EMS as essential, only four states designated it as such in 2014, and no localities had done so. The report concludes that aligning funding and classification with public values is crucial. It emphasizes the importance of field trauma triage protocols to ensure victims reach appropriate care levels, noting that transport to Level 1 trauma centers reduces mortality risk. Future efforts should focus on linking EMS data via the National Emergency Medical Services Information System (NEMSIS) with fatality and hospital data to better understand outcomes. The report also advocates for bystander training programs to improve pre-EMS care.
