Part 1: Diagnosis and initial assessment <strong>of</strong> ASD<br />

1.1 Identification and diagnosis<br />

Part 1<br />

Summary <strong>of</strong> recommendations<br />

Recommendations:<br />

Grade<br />

1.1.1 Early identification <strong>of</strong> children with autism spectrum disorder is essential. Early<br />

identification enables early intervention and is likely to lead to better function in<br />

later life.<br />

B<br />

1.1.2 A formal whole population screening programme for the identification <strong>of</strong> ASD<br />

is not recommended.<br />

B<br />

1.1.3 <strong>Health</strong> and education pr<strong>of</strong>essionals should take regular opportunities (at least<br />

at 8–12 months, 2–3 years and 4–5 years) to discuss the child’s development<br />

with parents as part <strong>of</strong> ‘surveillance’ to detect and respond rapidly to any<br />

developmental concerns.<br />

C<br />

1.1.4 Age <strong>of</strong> detection/diagnosis <strong>of</strong> all developmental problems, including ASD as a<br />

specified disorder, should be audited.<br />

C<br />

1.1.5 Parental inquiries regarding developmental concerns about their child must be<br />

taken seriously and addressed appropriately.<br />

B<br />

Good Practice Points:<br />

1.1.6 At each health or educational pr<strong>of</strong>essional encounter, concerns should be elicited<br />

regarding child development.<br />

1.1.7 All health and education pr<strong>of</strong>essionals involved in care <strong>of</strong> children should know<br />

referral pathways for those children about whom concerns are raised.<br />

The benefits <strong>of</strong> the early identification <strong>of</strong> children with ASD are well recognised by parents and<br />

pr<strong>of</strong>essionals (Recommendation 1.1.1). Identification <strong>of</strong> some health conditions is undertaken by<br />

‘screening’, which is defined as the formal identification <strong>of</strong> a previously unrecognised disease or<br />

condition by the application <strong>of</strong> tests, examinations or other procedures that can be applied to a whole<br />

population. However, the United Kingdom National <strong>Autism</strong> Plan for Children (NAPC) review <strong>of</strong><br />

the literature found no supporting evidence for implementation <strong>of</strong> a population-screening tool for<br />

identification <strong>of</strong> people with ASD 11 (Recommendation 1.1.2). Their findings supported the consensus<br />

that parents or pr<strong>of</strong>essionals with knowledge <strong>of</strong> normal development can identify ASD. Early<br />

identification <strong>of</strong> ASD can only take place with regular developmental surveillance by parents and/or<br />

health and early education pr<strong>of</strong>essionals.<br />
