Trial interventions
RECRUITMENT
MT (online Supplementary Fig. S1) was a multi-component intervention that included CAMHS training, systematic identification of YP approaching SB, a structured assessment (TRAM) and feedback of the TRAM findings to the CAMHS clinician (via the TRAM summary report). Prior to opening to recruitment, CAMHS clinicians at the intervention sites were invited to a single standardised training session on good/effective transition and interpretation of the TRAM summary report. Once the TRAM summary report relating to a participant (online Supplementary Fig. S2) was ready, it was sent to the CAMHS clinician along with a letter advising that it should be discussed with the YP and parent/carer and attached to any referral letter to AMHS (online Supplementary Fig. S3). To reinforce the learning undertaken during training, a leaflet reminding the CAMHS clinician why care in transition is important, and what YP say helps them with transition, was also included (online Supplementary Fig. S4). Clinicians in the UC group did not receive the TRAM summary report or any training regarding transition.
