Measuring the service system impact of a novel telediagnostic service program for young children with autism spectrum disorder

As prevalence of autism spectrum disorder continues to increase, so too does the need for timely, accessible diagnostic consultation. The present work extends from a previous study which provided preliminary evidence for the feasibility of expert clinicians to utilize telemedicine to triage autism spectrum disorder risk in young children. However, it did not examine whether a telediagnostic model had a demonstrable impact on tertiary care center referrals and usage. We therefore examined whether the introduction of telemedicine-based diagnostic consultation for families served by a rural medical facility affected referrals overall as well as to a metropolitan tertiary care diagnostic center. Results suggest that telemedicine diagnostic consultation in partnership with a referring early intervention system may positively impact referrals for diagnostic evaluation as well as the ability of families to schedule and attend appointments
