We are writing to draw attention to the lack of clarity provided by the Royal College of Psychiatrists regarding the role of the core trainee psychiatrist in assessing child and adolescent psychiatry patients out of hours. We believe it is important this issue is addressed as it confers broad implications for training, recruitment and service delivery. Crises of paediatric mental health tend to present out of hours. Ireland's 4th annual child and adolescent mental health service report details ‘striking patterns in the number of [self-harm] presentations seen’: 51% of presentations were in the 8-hour period of 7pm to 3am. ¹ This finding appears typical for paediatric psychiatry liaison services around the UK.

It is well known that in some trusts core trainees are excluded from child and adolescent mental health services (CAMHS)-led out-of-hours care pathways. This situation seems particularly unsatisfactory given that placements in developmental psychiatry are no longer obligatory. By failing to adequately furnish our future adult psychiatrists with skills in child and adolescent mental health, we are reinforcing a culture whereby young people are potentially falling through the care gap between CAMHS and adult mental health services. ^{Reference Singh2,Reference Singh, Paul, Ford, Kramer and Weaver3} Indeed, this very issue is highlighted in a joint paper from the inter-faculty group of the child and adolescent psychiatry and the general and community psychiatry faculties which presents recommendations for the provision of psychiatric services to adolescents and young adults. ^{Reference Lamb, Hill, Kelvin and Van Beinum4} Furthermore, by restricting the level of exposure to child psychiatry, we are doing little to encourage core trainees to perceive the specialty as a future career option.

As well as having an impact on the quality of training, the issue has far-reaching implications for patient care. The current lack of clarity fosters an atmosphere of uncertainty as situations arise where no one knows who holds responsibility to clerk a young person on arrival, thereby leading to potential delays in the patient being seen. Emergency department delays are a source of great concern to acute care trusts and create negative attitudes to psychiatric services in general. If we cannot manage to work in a safe and effective way, we are further contributing to the hostility not only towards our specialty but also to our patients, who are at their most vulnerable.

It is therefore our view that there should be an explicit expectation for core trainees to have exposure to the full range of acute psychiatric presentations, including child and adolescent patients, out of hours. It is of course essential that this experience would be supported by robust and accessible supervision structures in the form of a second on-call specialty trainee or consultant child psychiatrist. Although we recognise that the College is unable to tell trusts how to deliver their out-of-hours services, it would be helpful if the core psychiatry curriculum contained more robust guidance as to the role of the core trainee in assessing child and adolescent psychiatry cases out of hours. Such a move would help to create clarity as well as holding local education providers to account.
