Clinical Characteristics of Youth with Autism or Developmental Disability during Inpatient Psychiatric Admission

Children with autism spectrum disorder and developmental disabilities (ASD/DD) often experience severe co-occurring psychological and behavioral challenges, which can warrant inpatient psychiatric care. However, very little is known about the characteristics and clinical care of children with ASD/DD within the context of inpatient psychiatric settings. In this paper, we describe factors unique to inpatients with ASD or DD, by drawing on electronic health records from over 2300 children and adolescents ages 4-17 years admitted to a pediatric psychiatric inpatient unit over a 3-year period. Patients with ASD/DD accounted for approximately 16% of inpatients and 21% of admissions, were younger, more likely to be readmitted, more likely to be male, and more likely to have Medicaid insurance, as compared to patients without ASD/DD. Clinically, those with ASD/DD more frequently had externalizing concerns documented in their records, in contrast to more frequent internalizing concerns among other patients. Within the ASD/DD group, we identified effects of patient age, sex, and race/ethnicity on multiple dimensions of clinical care, including length of stay, use of physical restraint, and patterns of medication use. Results suggest the need for psychiatric screening tools that are appropriate for ASD/DD populations, and intentional integration of anti-racist practices into inpatient care, particularly with regard to use of physical restraint among youth.
