In its’ efforts to address syphilis, the Pima County Health Department (PCHD) in Arizona collaborated across health department divisions to create a new field-based, trauma-informed service delivery model. PCHD enhanced its traditional outreach efforts by deploying small interdisciplinary teams which operated out of a central van and tent to have regular contacts with individuals living in encampments. Read about how PCHD offered both clinical and non-clinical services to address the basic needs of the community through innovative approaches and regular, respectful engagement. Key lessons include the need for multidisciplinary, trauma-informed approaches, collaboration across the health department and with community partners, and a culture of innovation with leadership support.
