The effects of primary prevention policies on mortality from motor-vehicle crashes among children in the United States.

Introduction: Every year, 4500 children die in motor-vehicle crashes in the United States, with estimated costs of more than $40,000 and $240 billion in productivity losses. The majority of deaths and injuries are associated with improper use of restraint devices, alcohol, high speeds, and built environments.

Out-of-hospital cardiac arrest: first documented experience in a Mexican urban setting.

Objective: Out-of-hospital cardiac arrest is one of the leading causes of death in Mexico, but many survival and prognostic factors are unknown. The aim of this study was to assess out-of-hospital cardiac arrest in a Mexican city.

Methods: This was a prospective, cohort study that evaluated the records of the major ambulance services in the city of Queretaro, Mexico.

The prehospital emergency care system in Mexico City: a system's performance evaluation.

Introduction: Mexico City has one of the highest mortality rates in Mexico, with non-intentional injuries as a leading cause of death among persons 1-44 years of age. Emergency medical services (EMS) in Mexico can achieve high levels of efficiency by offering high quality medical care at a low cost through adequate system design.

Objective: The objective of this study was to determine whether the prehospital EMS system in Mexico City meets the criteria standards established by the American Ambulance Association Guide for Contracting Emergency Medical Services (AAA Guide) for highly efficient EMS systems.
