Older age at the time of autism spectrum disorder diagnosis was associated with a higher likelihood of psychotropic medication in children aged 6-11, according to Katharine Zuckerman, MD, and her associates.
The mean age at diagnosis for the 722 children included in the study was 4.4 years, with a mean diagnostic delay of 2.2 years. The adjusted odds ratio for psychotropic drug use in children who were diagnosed with autism spectrum disorder (ASD) after the age of 4 was 3.09, compared with children diagnosed before the age of 4. Children diagnosed at a later age were less likely to receive behavioral intervention (BI) therapy (adjusted odds ratio = 0.44), complementary and alternative medicine (aOR = 0.63), and school-based therapy (aOR = 0.38).

Children who experienced at least 2 years of delay before diagnosis were also significantly more likely to use psychotropic drugs (aOR = 1.77), and less likely to receive BI therapy (aOR = 0.54) and school-based therapy (aOR = 0.59). However, a delay of at least 2 years was associated with a greater chance of receiving complementary and alternative medicine (aOR = 2.81).
“Results suggest that if long-term ASD therapy use is a priority, payers and policymakers may need to proactively accelerate diagnosis by incentivizing screening or enhancing case management of children at high risk of diagnostic delays. From a population standpoint, as children receive earlier ASD diagnoses, payers may expect changes in service use patterns toward more therapy use and less pharmacology,” the investigators wrote.
