Background: The U.S. health system presents formidable challenges to the timely receipt of high quality care, especially for vulnerable children (e.g., those in families of color, lower SES, limited English ability). This population is at greatest risk for poor health outcomes. Children with asthma are an important vulnerable subgroup. Asthma, with an estimated prevalence of 6.9%, is the most common chronic condition in children. It is the most frequent reason for pediatric hospitalization and is a condition with documented disparities in care outcomes.
