The RITA-T (Rapid Interactive Screening Test for Autism in Toddlers) Community Model to Improve Access and Early...

Area of Science:

• Developmental Pediatrics
• Autism Spectrum Disorder Research
• Healthcare Systems Integration

Background:

• Early identification of Autism Spectrum Disorder (ASD) is crucial for timely intervention and improved outcomes.
• Existing referral pathways to specialized autism diagnostic clinics can involve significant wait times.
• Integrating screening tools into primary care and early intervention settings can enhance accessibility.

Purpose of the Study:

• To assess the effectiveness and generalizability of the Rapid Interactive Screening Test for Autism in Toddlers (RITA-T) model.
• To evaluate the impact of partnerships between Primary Care (PC), Early Intervention (EI), and Autism Diagnosticians on ASD identification.
• To compare diagnostic wait times and outcomes for toddlers screened via the RITA-T model versus standard referral.

Main Methods:

• A 3-year project (2018-2021) involving 15 EI centers and 9 PC centers (including MDs and NPs).
• Training of healthcare providers on the RITA-T tool and implementation of screening models.
• Retrospective chart review comparing wait times and diagnoses for 377 toddlers in the RITA-T group versus regular referral.

Main Results:

• The RITA-T model resulted in an average diagnostic wait time of 2.8 months, reducing delays.
• Consistent RITA-T cut-off scores were observed, indicating reliability.
• Participating providers reported increased confidence and ease of integrating the RITA-T model into their practice.

Conclusions:

• The RITA-T screening model is generalizable across different healthcare settings (PC, EI).
• Implementation of this model significantly improves the early identification of ASD in toddlers.
• Community-based screening fosters collaboration among providers, enhancing the diagnostic pathway.
