This Guide is based on Palm Beach County's experiences during the formation and implementation of their tried and tested Healthcare Emergency Response Coalition (HERC)_now a national model_and can serve to direct your community in establishing its own HERC. It provides guidance for developing and sustaining a successful HERC by outlining the steps and activities needed to begin and providing a list of policies and procedures that can be implemented and resources that can be consulted. This information can be applied and customized to any community's specific needs and resources to implement a program that will address any size disaster or healthcare emergency that presents itself.
