Healthcare service use patterns among autistic adults: A systematic review with narrative synthesis

Autistic adults often have complex healthcare needs due to factors like having other health conditions, sensory sensitivities, and limited access to healthcare providers who are trained to provide care for them. All these factors may influence the healthcare services that autistic adults use. In this review, we searched six electronic research databases to gather the most recent evidence about how often autistic adults use five important healthcare services (the emergency department, hospitalization, outpatient mental health, preventive services, and primary care) compared to populations of non-autistic adults. A total of 16 articles were ultimately included in this review. Most articles found that autistic adults had equal or higher use of healthcare services than non-autistic adults. Autistic adults frequently used the emergency department and hospital. This may indicate that routine outpatient care in the community is not meeting their needs. Our findings show the importance of improving care at this level for autistic adults to reduce overuse of the emergency department (in this article referred to as ED) and hospital.
