STUDY OBJECTIVE: We compare reported crash rates for US ambulances responding to or transporting patients from a 911 emergency scene with or without lights and sirens. Our null hypothesis is that there will be no difference in the rate of ambulance crashes whether lights and sirens are used. METHODS: For this retrospective cohort study, we used the 2016 National EMS Information System data set to identify 911 scene responses and subsequent patient transports by transport-capable emergency medical services (EMS) units...

Background: Emergency medical services (EMS) personnel face a disproportionally high risk for fatality and injury due to the nature of their work; and current ambulance and EMS equipment design standards do not adequately safeguard EMS personnel from sacrificing personal safety for patient care, a known human factors and ergonomic (HFE) design challenge. Despite the desire to include HFE interventions or considerations into a standard, the effectiveness of existing HFE interventions for EMS is unclear. Objective: Therefore, this study aimed to synthesize the peer-reviewed literature on the design features of patient compartments and EMS equipment that affect EMS personnel's performance or well-being...

Introduction: Errors are frequent in health care and Emergency Departments are one of the riskiest areas due to frequent changes of team composition, complexity and variety of the cases and difficulties encountered in managing multiple patients. As the majority of clinical errors are the results of human factors and not technical in nature or due to the lack of knowledge, a training focused on these factors appears to be necessary. Crisis resource management (CRM), a tool that was developed initially by the aviation industry and then adopted by different medical specialties as anesthesia and emergency medicine, has been associated with decreased error rates...

Stress is a state of the mind, involving both brain and body as well as their interactions; it differs among individuals and reflects not only major life events but also the conflicts and pressures of daily life that alter physiological systems to produce a chronic stress burden that, in turn, is a factor in the expression of disease. This burden reflects the impact of not only life experiences but also genetic variations and individual health behaviors such as diet, physical activity, sleep, and substance abuse; it also reflects stable epigenetic modifications in development that set lifelong patterns of physiological reactivity and behavior through biological embedding of early environments interacting with cumulative change from experiences over the lifespan...
