Abstract

Abstract: Diagnosing autism spectrum disorder (ASD) is challenging, resource-intense and time-consuming due to clinical and etiologic heterogeneity. With the rapid increase in prevalence of ASD, higher demand for diagnostic assessment often means long waitlists for families, and limited access to specialized intervention and support. In 2013, the Alberta Children's Hospital-Autism Spectrum Disorder Diagnostic Clinic (ACH-ASDC) experienced a significant waitlist in the 12 to 36 months' population. A Quality Improvement Project was started in 2014; one program aim was to create an efficient, sustainable and evidence-based ASD diagnostic evaluation process. The redesigned diagnostic process included: 1) pre- and postassessment parent information sessions, 2) a screening appointment and 3) standardized clinical appointment pathways. Within its first year, the new process reduced wait times to under a month without an increase in resources, leading to an efficient diagnostic process being sustained since its implementation.
