This reflects the portion of LEND training grant devoted to support Improving Early Screening and Diagnosis of Autism in Underserved Populations. The purpose of this project is to determine if providing training and technical assistance on developmental delay and autism screening improves the overall timeliness of the American Academy of Pediatrics (AAP) recommended well-child visit screenings and referrals in rural communities. In an effort to improve the timing of screening diagnosis for children aged birth to 36 months from underserved populations, specifically minorities, low income, and rural families, who are at-risk for developmental delays and autism spectrum disorders, AZLEND trainees provide training and collect data at rural community health centers. Currently, six clinics in Santa Cruz and Yuma counties participate in this project. Interdisciplinary teams conducted in-depth interviews with each clinic to discuss process flows and determine the most feasible and least intrusive method for incorporating developmental screening into standard operating practice. Teams also trained all clinical staff to use the PEDS, PEDS-DM, and M-CHAT. Prior to training, baseline referral and diagnostic evaluation information was collected for all patients that were birth through 24 months of age. These data are part of traditional reports generated by the early intervention program and can be tracked by the diagnosing physician. In March and April 2013, the same data will be collected to determine if providing technical assistance and training improves timely developmental screening and referral. Assisting already overextended rural clinics integrate screening and referral practices into daily operations will ensure children from underserved populations receive timely diagnosis and intervention and reduce disparities typical for these groups. This project also supports physicians to follow the AAP recommendation of early screening and referral.
