Bridging the Gap in Autism Diagnosis: An Evaluation of a Novel Primary Care Training Model

The current study assesses the impact of an educational program designed to train primary care clinicians (PCCs) to diagnose children between age 18 and 36 months at high risk for autism spectrum disorder (ASD).

Two cohorts of PCCs completed an 8-session training over a 9-month period. Clinicians were surveyed at baseline and 3 months after training completion. Information was collected regarding PCCs knowledge of ASD, their diagnostic beliefs, and perceived comfort and competence regarding all aspects of an ASD diagnostic evaluation.

A total of 35 participants completed training, and 29 (82%) completed presurvey and postsurvey. At baseline, 89% of PCCs reported no additional training in developmental behavioral pediatrics or diagnosing children with ASD, although 31% had diagnosed a child with ASD in the past year. After training, PCCs reported significantly greater comfort diagnosing ASD in children between age 18 and 36 months with mild ASD (2.31 vs 3.02, p < 0.0001), moderate ASD (3.03 vs 3.83, p < 0.001), and severe ASD (3.45 vs 4.34, p < 0.0001). PCCs also reported a significant increase in their knowledge and perceived competence in completing an autism evaluation, including taking an autism history, completing a structured observation, scoring the Childhood Autism Rating Scale-Second Edition, writing a letter of medical necessity, and discussing findings with families.

After training, PCCs reported a significant improvement in their knowledge, comfort, and competence regarding all aspects of diagnosing young children 18 to 36 months of age at high risk of ASD. PCCs can help to improve access to services for young children at risk for ASD.
