Barriers to Genetic Testing Faced by Pediatric Subspecialists in Autism Spectrum Disorders
Objectives While national medical guidelines recommend genetic testing for all individuals with non-syndromic autism spectrum disorder (ASD), there is underutilization of genetic testing. This study aims to define the perspectives and approaches to initial genetic testing of ASD diagnosticians in order to improve utilization. Methods A prospective cross-sectional study was conducted using an anonymous online survey distributed to 59 staff neurologists, developmental-behavioral pediatricians, psychologists, post-graduate physician fellows, and nurse practitioners from a single academic medical center. Questions explored knowledge, attitudes, and practices of initial genetic testing for ASD among diagnosticians. Results Among the 30 respondents (51% response rate), a lack of comprehensive pre-test genetic counseling was identified and forgetfulness was the most prevalent reason for not recommending genetic testing (n = 7/23, 30%). Insurance prior authorization (PA) for genetic testing was a major barrier for clinicians. More than half of respondents (n = 13/25, 52%) reported being uncomfortable with the PA process. Conclusions Variability in knowledge and practices among ASD diagnosticians regarding genetic testing was identified. Therefore, potential interventions like clinician and administrative staff education, as well as genetic counselor integration into ASD clinics, may be useful to improve genetic testing utilization..
