Long waits for autism diagnosis are a big problem in many parts of the United States. In Missouri many families wait nearly a year and must travel far to reach specialty centres. Researchers at the University of Missouri School of Medicine worked with the company Cognoa to test an FDA-approved device called CanvasDx. The device uses AI and patient information to predict a positive or negative autism diagnosis. If the information is not clear, it returns an "indeterminate" result.
The study used the ECHO Autism community to work with primary care clinicians. Keeping care local helped families get a diagnosis several months sooner. In the sample of 80 children the device gave determinate results for about half and did not produce false positives or false negatives, and it never contradicted a clinician's diagnosis.
