Young people (YP) with attention deficit hyperactivity disorder (ADHD) are recognized to be a group who are particularly vulnerable to falling through the gap regarding transitioning from Child and Adolescent Mental health Services (CAMHS) to Adult Mental Health Services (AMHS). This presentation will combine a systematic review of the literature with some clinical examples of the pathway for a number of YP with ADHD who reach the transition boundary (TB).

(1) Databases (e.g., PubMed, PsycINFO, AMED, CINAHL, EMBASE, Web of Knowledge), and grey literature, were searched systematically with database-specific key words, variants and truncations, to cover six subject areas: ADHD; transition or transfer; age; experiences or views; service development; and policies or protocols. Hand searching of key journals, ancestry and forward searches of references, and expert consultation were conducted. Two reviewers critically evaluated studies using a validated appraisal tool for mixed methodologies and findings were synthesized. (2) Following ethical approval, CAMHS clinicians from 9 clinics in Republic of Ireland identified all cases where a YP with ADHD had reached the TB, and identified referral/service outcomes (n = 20).

The search yielded 27 studies, covering areas of service review and recommendations (7), guidelines (3), medication (5), case note audit (3), professional's views (5), pilot transition clinics (2). A further set of papers covered the perspective of the young person (4) and parent (2). Overall these highlighted the less than optimum experience by both clinicians and service users of the experience with suggestions for future developments. These findings were mirrored in the review of clinical notes and individual interviews of YP identified through their CAMHS. Of the 20 young people identified, only 1 was directly transferred to AMHS. Eight were retained in CAMHS, on average for over a year. A significant number (7) refused onward referral. A perception from CAMHS clinicians, that AMHS did not accept such cases or lacked relevant service/expertise, may have contributed to the low rate of referral.

Both the extant literature and the specific study presented highlight the lack of clear cut consensus about the appropriate management of young people with ADHD have who reach the transition boundary. Low rates of AMHS transfer may come from CAMHS clinicians’ perceptions of AMHS, and preferences of young people and families. Before assuming the very low rate of referral by CAMHS clinicians is poor practice, clinical outcomes need to be identified, young people's reasons for refusing transfer explored and service options identified.
