Autism Diagnosis

Autism Spectrum Disorder - An Overview

Autism spectrum disorder (ASD) is a brain-based disorder characterized by social-communication challenges, and restricted and repetitive behaviors, activities, and interests.  In the most recent data from 2018 from the Centers for Disease Control’s (CDC) Autism and Developmental Disabilities Monitoring (ADDM) Network, it is estimated that 1 in 59 children has been identified with ASD.  Ten years prior (in 2008), the prevalence of ASD was estimated at 1 in 88 by the CDC ADDM Network.
 
ASD is diagnosed more than 4 times as frequently in boys than in girls, and occurs across all racial, ethnic, and socioeconomic groups.  More white children are identified with ASD than black and Latinx children.  Some barriers to identification have been cited as lack of access to healthcare due to lower socioeconomic status or citizenship status, language, and stigma.  Although prevalence ratios comparing different racial and ethnic groups were lower in the most recent ADDM report than in previous reports, black and Latinx children still continue to be screened and referred to services less frequently than white children.
 
Despite the growing prevalence of ASD, fewer than half of children with ASD receive their first developmental evaluation by 3 years of age and, subsequently, more than half receive a diagnosis after 4 years of age.  Primary care providers (PCP) are uniquely positioned to screen and help identify children with ASD. The American Academy of Pediatrics (AAP) recently published a new clinical care guideline “Identification, Evaluation, and Management of Children With Autism Spectrum Disorder” in January 2020.  There is also a complementary online course by the AAP entitled “Identifying and Caring for Children with Autism Spectrum Disorder: A Course for Pediatric Clinicians” which is offered at no cost until 4/19/2023.  Participants can earn up to 6.5 AMA PRA Category 1 Credits, 6.50 NAPNAP contact hours, and 6 MOC Part 2 credits for free.

DSM-V ASD Criteria

Deficits in social communication and interaction, Restricted repetitive behavior or interests
DSM-5 2013 Book

Additional DSM-V Requirements:

  • Symptoms present in early development.
  • Symptoms cause clinically significant impairment in functioning:
Level 3: requiring very substantial support
Level 2: requiring substantial support
Level 1: requiring support
  • Disturbances are not better explained by a diagnosis of intellectual disability or global developmental delay

It all begins with surveillance and screening

The AAP recommends that developmental surveillance be conducted at every well-child visit.  Developmental screenings should be administered whenever there is a developmental concern (e.g. parent/teacher/clinician concern, child showing unusual behaviors consistent with ASD, delays in social-emotional milestones, etc.).  They should also be administered at the time intervals captured in the table below.

AAP Recommendations for Developmental Screening

Developmental screening with a standardized tool is more effective than surveillance alone

Developmental Delays:

Without screening: 30% identified
With screening:70-89% identified


Mental health problems:

Without screening: 20% identified
With screening: 80-90% identified

Places to find surveillance and screening tools:

CDC Developmental Monitoring and Screening for Health Professionals

Considerations for Busy Practices and Diverse Families

  • Many general developmental and autism specific screens only take 5-10 minute to administer.
  • Most screens are parent questionnaires and written at a 5th grade level or below.
  • Some screens are available in Spanish and other languages.
  • Some parents may need help answering questions—consider creating a protocol for oral administration for families with low literacy.
  • Reimbursement for screening can be received by using CPT code 96110.

When to Refer

  • Refer if there is a positive screen or clinical concern.
  • Refer immediately to early intervention services if child is under 3 years old, or to special education if child is 3 years and older.  Do not delay these referrals.  An ASD diagnosis is not required to receive these services.
  • Refer for audiology evaluation.
  • Refer to ASD specialist which may include a Centers of Excellence (COE) in autism, clinical psychologist, or developmental specialty diagnostic center such as the UW Center on Human Development and Disability, Seattle Children’s Autism Center, the UW Autism Center, Providence Boyden Family Autism Center, or the Mary Bridge Developmental Behavioral Pediatrics department.
  • Consider referral for other rehabilitative treatment such as occupational therapy or speech therapy.
  • Directly refer to program if possible as referrals are more likely to be completed if you have the program reach out to the family.
