Additional Studies Aim at Streamlining Diagnosis
Two additional studies also evaluated strategies to streamline the diagnosis of ASD. Both were positive. In one, the accuracy and time to diagnosis among pediatricians trained in TAP and CARS were compared with those of ASD specialists in a dedicated autism clinic. Both were located at Nemours Children’s Health Center, Wilmington, Delaware.
In this study, presented by Meghan Harrison, DO, an attending pediatrician at Nemours Children’s Health, time to diagnosis among the 39 patients evaluated by pediatricians relative to the 349 patients evaluated at the dedicated ASD center (2.0 vs 5.1 months; P = .001) was significantly shorter. The age at diagnosis in the pediatrician-assessed population (27.5 vs 36.5 months; P < .001) was also significantly younger.
In another study, led by Ashely L. Early, MSW, a clinical social worker at the Medical University of South Carolina, Charleston, South Carolina, switching to a screening tool called the Rapid Interactive Screening Test for Autism in Toddlers (RITA-1) reduced the wait time to evaluation by approximately 5 months relative to previous practice with a more cumbersome screening method.
An ‘Urgent Need’ to Accelerate Diagnosis
In most places in the United States, children suspected of ASD are referred to specialists for confirmation of the diagnosis, which is needed to quality for ASD services, according to Katherine Zuckerman, MD, a professor of pediatrics the Oregon Health and Science University, Portland, Oregon. Dr. Zuckerman, who was moderator of the session in which all four of these abstracts were presented, explained that there is an urgent need to accelerate the time to diagnosis, which involves long delays for many if not most children with ASD. This is important because treatment and supportive services for ASD are almost always dependent on a diagnosis.
“There are tons of data to show that earlier access to ASD services has important patient benefits, including higher IQs,” she said. Other benefits she listed include a better quality of life for the child and the family.
“It can provide a huge reduction in family stress,” she added, suggesting that early interventions favorably modify the trajectory of the disability over time with accruing benefits.
“The lifetime costs of ASD exceed cancer and most other disease, so there are major implications for the cumulative cost of ASD management,” Dr. Zuckerman said. She suggested that the studies presented at the meeting reflect a likely evolution in who evaluates children for ASD and how quickly the evaluation is performed.
Dr. Rea, Dr. Harrison, Dr. Zuckerman, and Ms. Early reported no potential conflicts of interest. In addition to his executive role in As You Are, Dr. Hicks has financial relationships with Quadrant Biosciences and Spectrum Solutions.
