Forty-six subjects received primary medical care within an autism-specific medical home intervention ( www.autismmedicalhome.com ) and 157 controls received standard primary medical care. Subjects and controls had autism spectrum disorder diagnoses. Thirty-four subjects (74%) and 62 controls (40%) completed pre and post surveys. Controlling for pre-survey medical home status, subjects had 250% greater odds of receipt of a medical home at the study end compared to controls (p = 0.021). Compared to controls, subjects receiving the intervention reported significantly more satisfaction (p = 0.0004), greater shared decision making (p = 0.0005) and fewer unmet needs (p = 0.067). However, subjects reported no change in family stress (p = 0.204).
