Specifications include, but are not limited to: The Maricopa County Department of Public Health (MCDPH) is requesting letters of interest from community-based organizations (CBO) that would be interested in collaborating on a grant application issued by the Centers for Disease Control (CDC). MCDPH is seeking partners to assist the public health department to build an infrastructure of overdose surveillance, harm reduction, recovery, and care in communities most impacted by the overdose crisis. The evolving drug problem is complex and dynamic, requiring locally tailored and culturally relevant solutions. A strong foundation of cooperation and partnership across public health, behavioral health, health systems, community organizations, and public safety is necessary to build overdose infrastructure and cohesive programs that have multiple access points and address health inequities in overdose cases. The OD2A: LOCAL grant is a five (5) year grant that aims to use data to drive action steps that reduce overdose morbidity and mortality in communities quickly, while addressing health disparities. The grant is primarily focused on opioid, stimulant, and polysubstance. Data generated from surveillance, the evaluation of prevention programs, and by community partners will be used to inform the implementation and improvement of overdose prevention activities.
