Equity as the fourth ‘E’ in the ‘3 E’s’ approach to injury prevention

The education, engineering and enforcement (3 E's) approach to injury prevention is grounded in assumptions that it is effective for everyone; however, evidence demonstrates that it fails to consider opportunities for all populations to experience safe and injury-free lives. In this way, the 3 E's approach does not support health equity in the injury prevention field. In this brief report, we argue that a fourth E, equity, must also be used with the 3 E's approach to injury prevention.
