Inpatient Children and Adolescent Mental Health Services (CAMHS): outcomes of young people with and without intellectual disability

Abstract

Background: Little is known about the effectiveness of inpatient care for young people with co-morbid mental illness and intellectual disability (ID). This study aims to compare the demographics and outcome of young people with mental illness with or without ID admitted to psychiatric hospital. A secondary aim is to look into the outcome of those with ID admitted to general mental health young people's units.

Method: Data were collected on the outcome of young people's admissions to specialist ID and general adolescent mental health units as part of a larger quality improvement project run by the College Centre for Quality Improvement. Health of the Nation Outcome Scales for Children and Adolescents (HoNOSCA) scores were completed by local clinical staff at admission and discharge on 38 young people with and 113 people without ID from 14 units.

Results: Young people with mental disorders significantly improved clinically over the admission whether or not they had ID. There were no differences between the groups in age or use of the Mental Health Act but people admitted with ID were more likely to be male and had longer lengths of stay. Admission to a general adolescent unit was associated with clinical improvement for people with ID.

Conclusions: This study needs replication because of the small sample and incomplete data but it suggests that young people with ID and mental disorders significantly improve clinically when admitted to hospital as do their non-disabled peers.
