The investigators hypothesize that children seen in a clinic that uses a compute based system known as CHICA, which reminds pediatricians to screen at defined time point for autism, will be screened more consistently for autism and receive more timely diagnostic a treatment services.

Primary Outcome Measures:
  • Structure autism screening instrument administered [ Time Frame: Up to 4 years ] [ Designated as safety issue: No ]
    Physicians are reminded by the computer system to screen children under 3 years of age for autism with a structured screening instrument. Chart abstraction is used to document whether or not the screening occurred.

Secondary Outcome Measures:
  • Are appropriate diagnostic studies conducted among children who screen positive for autism. [ Time Frame: Up to 4 years ] [ Designated as safety issue: No ]
    Among children who a suspected of having autism, chart abstraction and interviews are done to determine if the child received appropriate diagnostic and studies.

Estimated Enrollment: 124

Arms Assigned Interventions
Experimental: Computer based reminders to MD
Children in this arm attend a clinic that is randomly assigned to receive physician alerts to screen appropriate children for autism.
Other: Computer based care reminders
Physicians in the intervention clinic will receive computer generated reminders to screen for autism among children of appropriate age visiting the clinic.
No Intervention: Usual care arm
Children in this are receive usual care from a clinic randomly chosen to serve as a control.

Detailed Description:

To be eligible for this trial, participants must receive their care at one of four primary care clinics in Indianapolis where the CHICA system is used.
