Addressing current barriers to autism diagnoses through a tiered diagnostic approach involving pediatric primary care providers.
Let pediatricians make straightforward autism calls so kids begin ABA months earlier.
01Research in Context
What this study did
Wieckowski et al. (2022) wrote a position paper. They asked: can pediatricians handle the easy autism cases so kids start therapy faster?
The authors mapped a two-step plan. Step one: train primary-care doctors to spot clear-cut ASD. Step two: send only tricky cases to specialists.
What they found
The paper does not give new data. Instead, it lists barriers that slow diagnosis today—long waits, few specialists, and parents left hanging.
How this fits with other research
Howlin et al. (2006) surveyed parents and found the same pain point: families are happier when fewer doctors touch the case and answers come early. Trubanova’s tiered plan answers that call.
Phaneuf et al. (2011) already showed a three-tier model works for parent training—start simple, add layers only when needed. Trubanova extends the same logic to diagnosis.
Guillon et al. (2022) polled European families and confirmed shorter waits and clear guidance drive satisfaction. The new paper turns that evidence into a concrete workflow for U.S. clinics.
Why it matters
If you work with toddlers showing red flags, you can shorten the runway to ABA. Ask the pediatrician to run an M-CHAT and a brief observation visit. If scores are high and signs are classic, urge them to diagnose and refer straight to you while the specialist appointment is still months away. Early start, happier parents, better outcomes.

03Original abstract
Formal autism diagnosis from a specialist trained in autism assessment is customary prior to a child accessing early, intensive autism-specific services. However, long wait lists for diagnostic evaluations and limited specialty workforce have created substantial delays. Additionally, lengthy multidisciplinary evaluations are costly to insurers, inconvenient to families, and disproportionally impact under-resourced families. Diagnostic delays can impede access to intervention services. These barriers, combined with evidence regarding the importance of receiving early, autism-specific treatment, demand new approaches enabling access to autism specific services before comprehensive evaluation. Pediatric primary care providers (PCPs) are often the only health care professionals with whom a family interacts during early childhood and can play a crucial role in helping children with autism symptoms access services. Many strategies for autism diagnosis in primary care are being developed and tested; however, they have yet to be broadly adopted by PCPs, primarily due to critical implementation barriers in primary care settings. There is also not enough evidence on the accuracy of PCPs' diagnostic impressions without extensive specialty support, resulting in PCP hesitancy in diagnosing ASD, as well as family and service provider hesitancy in accepting a PCP autism diagnosis. In this commentary, we explore the acute need for shortening waitlists for autism evaluations through a tiered diagnostic approach, in which PCPs can rule in or rule out autism in children, for whom diagnosis is clear, and refer more complex cases for specialist evaluations, and explore implementation challenges to this approach.
