Mental health admissions in paediatric populations in North Wales: two cohorts compared 1875–1924 and 1994–2008

OBJECTIVES To investigate frequency of under-18s admitted to mental health services (MHS) in North West Wales (NWW) between 1875 and 2008. There are claims that 1 in 10 children have a mental illness, but there are little data on their inpatient MHS utilisation. SETTING Looking at admissions at the secondary care level, three data samples were included; the first comprises historical asylum admissions, the second comprises contemporary admissions to acute psychiatric beds, and the third comprises admissions to district general hospital (DGH) beds that resulted in a mental health coding. PARTICIPANTS All were under 18. There were 65 historical patients, 41 contemporary mental illness admissions and 943 DGH admissions. PRIMARY AND SECONDARY OUTCOME MEASURES The primary outcome measures were diagnoses based on case notes of the historical cohort between 1875 and 1924, as well as details of paediatric admissions to MHS from 1994 to 2008 and paediatric admissions with a mental health component to the DGH in NWW. RESULTS The incidence of admission to a mental health bed was 1.55 per year in the historical cohort compared with 2.9 in the contemporary. The overall incidence of admission to any bed in the contemporary cohort was 129 patients per year. There has been a twofold increase in the incidence of admissions for schizophrenia and related psychosis, but this most likely stems from an earlier age of admission rather than a true increase. CONCLUSIONS There is a greater frequency of hospital admissions for youth under the age of 18 in NWW for mental health today than previously. The rates reported in the DGH sample are consistent with data from community surveys of patients meeting criteria for mental disorders and complement such data when it comes to planning for paediatric MHS. However, they also raise questions about the boundaries between disease and distress.
