The Children's Hospital of Philadelphia, or CHOP, case study is intended to offer providers, health insurers, public health departments and community-based organizations an overview of an asthma in-home intervention. Community Asthma Prevention Program, or CAPP, services primarily low-income, urban communities by providing community-based education, training, and environmental interventions. The goal of CAPP is to decrease asthma-related hospitalizations and emergency room visits by educating children and their families about asthma and about methods of identifying and mitigating environmental asthma triggers in the home.
