Cyclic variations in demand for out-of-hours services in child and adolescent psychiatry: Implications for service planning

Abstract

Aims and method: We examined peaks and troughs in demand for out-of-hours consultations and assessments in child and adolescent psychiatry and whether these have implications for service development. All out-of-hours referrals in three teaching hospitals providing services to a large and diverse inner-city population were prospectively registered from 1 January 2002 to 31 December 2005. Results: In total, 323 individuals under 18 years were referred; 21.6 (95% CI 19.3-24.0) per 100 000 general population per year. Bedside assessments were required in 37%, the remainder were dealt with by telephone. The work took more than 4 h for 22%; 46% of individuals presenting were aged 16-18 years. Significant diurnal variation was observed with a peak in referrals between 17.00 h and 00.59 h. More referrals were made when daytime liaison services were closed (odds ratio (OR) = 2.46, 95% CI 1.15-1.87), after referral pathways had been clarified (OR = 2.33, 95% CI 1.92-3.23) and during spring (OR = 1.50, 95% CI 1.14-1.98). Other factors analysed showed no association with referral activity. Clinical implications: Cyclic variations in the demand for out-of-hours services in child and adolescent psychiatry should be considered for service planning. Although paediatric psychiatric emergencies are relatively rare, they can take up considerable clinician time. Declaration of interest: None.
