An emerging picture has seen increasing numbers of young people with mental health crisis attend paediatric emergency departments in Ireland. Following paediatric review, many are referred to in-house paediatric liaison psychiatry (PLP) services. This pilot study describes referral patterns and practice over a 1-month period across three Dublin centres.

Case notes of all referrals to PLP were reviewed to extract relevant clinical and administrative data. For those admitted, costs associated with length of stay were estimated. Clinical profile, management and intra-hospital pathway differences were explored.

Fifty-nine young people under 16 years presented to one of the three EDs with an acute MH presentation. The sample consisted of 39 females (66%) with a mean age of 13.7 years. The majority (n = 34, 58%) presented out of hours. A substantial portion of youths presenting (n = 37, 63%) were admitted, and had a mean duration of stay of 4.51 days. There were differences between hospitals in terms of frequency of presentation with self-harm, admission rates and length of stay.

Different PLP service configuration, staffing and funding streams may explain some of the differences observed across centres, although the findings should be interpreted with caution given the limited sample size. Standardisation of service provision and management is needed for PLP services. Additional community CAMHS resourcing is needed to support the development of alternative pathways for youth in need of urgent MH review.
