ECHO Autism Washington: Autism Diagnostic Evaluations in Primary Care.

ECHO ( Extensions for Community Healthcare Outcomes ) Autism is a telementoring learning model to increase community capacity for autism-related health care. Seventy-seven pediatric providers (mostly primary care, seeing exclusively Medicaid patient populations) enrolled in 1 year of ECHO Autism Washington . Analysis of self-report surveys showed a significant increase in autism diagnoses made by ECHO providers after 1 year, F (1, 65) = 7.52, P = .008. Providers who attended more sessions reported making more diagnoses, F (2, 613.26), P = .045. Of note, autism diagnoses were not externally validated. The total number of reported barriers reduced, F (2, 61) = 13.5), P < .001, and confidence ratings increased F (2, 60) = 24.21, P < .001. The average number of diagnostic referrals from ECHO providers to the state's largest autism specialty clinic significantly reduced, t (43) = 4.23, P < .001, with significantly fewer diagnostic referrals made during and after ECHO training compared with a comparison group of 28 non-ECHO providers, t (58.77) = -3.36, P < .001. Overall, 1 year of ECHO Autism Washington participation led to significant changes in autism diagnostic practices.
