For 25 years, the American Academy of Pediatrics (AAP) Community Access to Child Health (CATCH) program has supported pediatricians in collaborating within their communities to advance the health of all children. CATCH grants support pediatric residents and pediatricians in planning or implementing community-based child health initiatives. The CATCH program has provided almost 10 million dollars through 842 planning, 585 resident, and 305 implementation grants to >1700 pediatricians. Urban, rural, suburban, and tribal communities in every state as well as the District of Columbia and Puerto Rico have benefited from CATCH-funded projects. Collaborations with community partners such as schools, homeless shelters, and mental health centers have led to programs serving children and families, especially those living in poverty and in minority groups. The most recent program data reveal that 87.5% of the projects are operating 2 years after funding. Many CATCH projects have not only sustained themselves but have grown into larger programs with funding from other sources. CATCH has influenced pediatricians' careers by providing important skills, networking opportunities, career legitimacy, mentoring opportunities, and increased engagement with the AAP. More than 350 pediatricians have served the AAP as CATCH facilitators, the network of physicians that provides technical assistance to applicants and reviews grant applications. Responding to changing trends, CATCH leaders have looked at other funding models and recently launched the CATCH-On initiative. CATCH-On creates and provides templates from successful CATCH projects to busy pediatricians who can then implement the project in their communities with minimal funding.
