Child Health Alliance & Mobilization Partnership 419 (CHAMP 419) - Child Health Alliance & Mobilization Partnership 419 (CHAMP 419) is a coordinated, community-driven initiative led by the Health Council of Northwest Ohio (HCNO) and designed to reduce childhood chronic illness in two Ohio demonstration communities: Toledo Metro (Lucas County) and Sandusky (Erie County). The project addresses rising rates of asthma, obesity, metabolic disease, and related preventable conditions by integrating clinical care, environmental health, nutrition access, and family centered supports across high burden census tracts. CHAMP 419 advances the Great Health for America vision by aligning local partners, federal collaborators, and community residents around shared governance, evidence-based interventions, and transparent data systems. Children in both communities face layered risks: aging housing with lead and mold hazards, poor air quality, limited access to nutritious foods, and high Medicaid insured populations experiencing preventable emergency department use. CHAMP 419 responds to these conditions through a comprehensive approach grounded in community engagement, data integration, and multi domain intervention planning. The project establishes Executive and Practitioner Coalitions in each community to guide strategic direction, interpret Community Health Assessment (CHA) findings, select the anchor chronic condition, and ensure interventions are rooted in local context. Coalitions include families, schools, health systems, public health agencies, social service providers, and neighborhood organizations, with emphasis on representation from high burden tracts. CHAMP 419 strengthens regional cohesion by creating structured opportunities for Toledo and Sandusky partners to learn from one another, align approaches, and elevate shared priorities while honoring the distinct assets and needs of each community. CHAMP 419 conducts a robust CHA using clinical data, Medicaid claims, environmental surveillance, school indicators, and social service utilization to identify root causes and geographic patterns of childhood chronic illness. Findings inform selection of the anchor condition—anticipated to be asthma in Toledo and obesity in Sandusky—and guide tract level intervention planning. Baseline measures feed directly into a rigorous Evaluation and Performance Measurement Plan. A secure, integrated data infrastructure and dashboard supports near real-time monitoring a broad set of data elements, cross sector coordination, and continuous quality improvement by unifying clinical, Medicaid, environmental, school, and social service datasets. Interventions span five domains: access to care, nutrition, physical activity and healthy environments, family and community engagement, and policy/systems change. Examples of possible interventions include mobile pediatric care, Food is Medicine programs, expanded nutrition education, school-based asthma management, Healthy Homes environmental mitigation, farm to school initiatives, and Community Health Worker support through the evidence-based Pathways HUB model. All interventions are evidence based or paired with prospective evaluation protocols and approved by HHS/CDC. CHAMP419 will leverage HCNO’s 50 years’ experience bringing multi-sector partners together to strengthen local capacity, reduce preventable hospitalizations and Medicaid costs, and improve childhood health outcomes through coordinated, community rooted action. By integrating data, aligning partners, and addressing environmental and social drivers of chronic illness, the project builds a sustainable regional model for improving child health that can be replicated beyond the demonstration communities.
