While an estimated one in 160 children globally suffers from Autism Spectrum Disorder (ASD), and 15% of children in the United States have Developmental Delays (DD), only half of pediatricians report the use of appropriate screening tools during Well Child Checks (WCC). Because referring patients to Early Intervention (EI) has a significant effect on patient outcomes, the American Academy of Pediatrics (AAP) has formulated general guidelines regarding screening for DD and ASD during WCC to improve timely diagnosis and appropriate referral. This project aims to determine the effectiveness of implementing screenings for DD and ASD during WCCs.
