Concordance between admission and discharge diagnosis of a child and adolescent psychiatry inpatient unit.

Abstract

Psychiatry is arguably the most medical practice that is affected by culture. The pediatric literature is sparse with respect to the differences between child psychiatric units in different cultures and different countries. In this study, we aim to investigate the discordance between admission diagnosis and discharge diagnosis for child psychiatric disorders. A retrospective analysis was conducted on 206 patients admitted to a university hospital inpatient child and adolescent psychiatry unit in Ontario, Canada. The data extracted from electronic charts were age, gender, DSM-IV-based diagnosis at admission, living arrangement before admission, length of stay (minimum one day), post-discharge diagnosis, and post-discharge outcomes. There was 75% agreement with the discharge diagnosis. We found strong negative and positive associations between conduct disorder at discharge and the prescription of antipsychotics (+), antidepressants (-), and stimulants (-), and there was a strong association between a conduct disorder (CD) diagnosis and medication-free status. The powerful effect size of stimulant medication was specific to the association between a primary diagnosis of ADHD (vs. not-ADHD) and stimulant medication (c2=127.5, df=1, phi=0.79, P<0.0001). We have found a significant agreement between admission and discharge diagnosis. It is suggested that the inpatient stay helped to refine the formulation and to improve the child's well-being.
