Integrating Human-Animal Care Through a Public Health-Driven One Health Clinic Model in Pima County, Arizona, October...

One Health clinics integrate human, animal, and environmental health to provide interdisciplinary health care and community resources to people experiencing homelessness (PEH). Five mobile, public health-led One Health clinics were newly implemented in Pima County, Arizona, during October 2023-February 2024. Clinic locations included parks, libraries, and homeless shelters to reduce transportation-related barriers and integrate public health, veterinary, and housing services. Originally designed for PEH and their pets, Pima County One Health clinics were open to everyone in neighborhoods where clinics were hosted to promote community engagement with clinics and strengthen relationships with public health. We evaluated the performance of these clinics by describing service patterns, client perceptions, and lessons learned to support development of clinics by other jurisdictions. During clinic visits, basic demographic information was collected for people and pets, along with data on housing status, environmental and resource concerns, use of clinic services, and perceptions of clinics. The first 5 monthly mobile community clinics served 108 clients and 93 pets; 44% of clients were unhoused or unstably housed, 36% of clients were housed, and housing status was unknown for 20% of clients. Clinics facilitated partnership among service providers and with housed and unhoused community members. Clinics supported vaccine uptake among people and their pets and identified 3 cases of sexually transmitted infections that might otherwise have remained undetected. By implementing a One Health Clinic framework, our local health department helped address gaps in human and veterinary health care services. Other public health agencies might consider implementing similar models to enhance public health engagement with local communities.
