Background and Aim : Different centers and organizations are involved in providing care to children with autism spectrum disorder (ASD) in Iran. The service delivery system is currently unstructured and fragmented. There is no comprehensive structure that defines the relationships and duties of all organizations and stakeholders in the field of care provision for patients with ASD. The purpose of this study was to identify the structures of health care delivery to children with ASD in other countries through Scoping Review.Methods : The Scoping Review framework developed was used for this study. The Medline, Scopus, SID and Magiran databases, Google Scholar Search engine were searched systematically, as well as manually search for selected journals and selected articles references, reports, government documents, guides, websites and other available information in the period 2000 to 2019. At least 1472 articles were screened step by step using PRISMA flowchart and finally 13 articles and 19 Guidelines related to the objectives were reviewed and synthesized. Data were categorized into data extraction tables in the form of models of care delivery, screening, methods and diagnostic tools, providers, interventions (ASD treatments).Results : The data were summarized in the data extraction tables in the form of models of care, screening, methods and diagnostic tools, providers, interventions (autism treatments). Nine different care models for people with ASD were extracted from the literature. Five Guidelines out of 10 reviewed Guidelines not recommended universal screening of ASD. The extracted diagnostic methods included reviewing child medical information history, interviewing parents, comprehensive medical evaluation, direct observation, cognitive assessment, adaptive performance measurement, use of standard diagnostic tools, alternative diagnoses, and evaluation of sensory integration processes. Direct observation detection was one of the most important diagnostic methods. In addition, among the reviewed Guidelines, all (Case 10) had recommended Physical Therapy. Based on the findings, 7 Guidelines had recommended pharmacological intervention.Conclusion : In designing a service delivery structure for children with ASD in the country, responsibilities of each organization as well as the coordinator and stewardship, care providers, screening and diagnosis process, and services, and rehabilitation and curative services and process, also Insurance coverage, social and economic support must be considered.
