The case studies are designed to inform policymakers and government officials; however, they are also meant to be used as a training tool. Each case has suggestions for cross-systems development and includes ideas about natural coalition partners in a specific area of injury or violence, as well as suggestions for other maternal and child health settings where a similar program could be developed. The programs are presented under 14 types of unintentional injury or violence: alcohol, firearms, bicycles, drowning, fires and burns, home safety, motor vehicles, occupational, playgrounds, sports, family violence, homicide/assault, sexual assault, and suicide. Each of the case studies contains the following information: start and end dates; target population; audience reached; program description (objectives, program components, summary of maternal and child health roles, coalition partners in prevention, sustaining the program, and adapting the program to community needs); resources needed; lessons learned; products/publications developed/used; and contact person.
