Autism spectrum disorder (ASD) presentations among referrals to a child and adolescent mental health service (CAMHS) inpatient unit in Ireland

This retrospective chart review aimed to identify the intersection between young people with Autism Spectrum Disorder (ASD)’s needs and CAMHS inpatient service needs. A retrospective chart review was conducted on all referrals to a CAMHS inpatient unit over three years (n = 352). Referrals which specified a formal diagnosis or suspected diagnosis of ASD were identified (n = 111), and basic demographic data were collected. Young people with either a formal or suspected diagnosis of ASD referred to the unit presented with a wide range of co-occurring conditions. Of these young people, 30 were admitted to the unit and only 6 of them were engaged with an ASD specialist service. Young people with diagnosed or suspected ASD were more likely to be admitted if they presented with suicidality. Males with diagnosed or suspected ASD were more likely to have a diagnosis of OCD while females with diagnosed or suspected ASD were more likely to present with eating and feeding disorders and personality development difficulties. Findings highlight the lack of a clear care pathway for young people with co-occurring autism or suspected autism and complex mental health problems.
