When should I refer a patient with ASD for specialist assessment or intervention?

Refer a patient with autism spectrum disorder for specialist assessment or intervention if there are reported or observed features suggesting possible autism, considering the severity, duration, and impact of these features across different settings, as well as parental or carer concern and the likelihood of an alternative diagnosis ¹.

Specifically, consider referral if there is concern about possible autism based on features such as developmental delays, social communication difficulties, or repetitive behaviors, especially if these features are present across multiple settings and significantly impact the child's functioning ¹.

Refer children and young people to the autism team if you are concerned about possible autism on the basis of reported or observed features suggesting possible autism, taking into account the factors associated with increased prevalence, such as a sibling with autism or neurodevelopmental conditions ¹.

Referral should also be considered if there is regression in language or social skills in children younger than 3 years, or regression in language or motor skills at any age ¹.
