The aims of this study were to describe the practice patterns for early screening and evaluation for ASD diagnosis in Bulgaria, as well as to identify potential barriers and facilitators in this process. We surveyed a sample of pediatricians and pediatric psychiatrists to analyze the use of standardized instruments, application of biomarkers, parental collaboration and future policy prospects. We found a significant support for the idea of a national program for ASD in Bulgaria. These insights provide an evidence-based analysis that could help improve services, guide research and inform policies in regard to ASD. Further work is necessary to better understand other stakeholders' opinions and perspectives, especially those of patients and their families.
