title: [Children and adolescents with hyperkinetic disorder. Frequency of the claims diagnosis in primary care based on the data of a regional Statutory Health Insurance Sample--Versichertenstichprobe AOK Hessen/KV Hessen (1998-2001)].
abstract: OBJECTIVE
  The study aims to estimate the frequency with which doctors of various groups submitted claims for the treatment of hyperkinetic disorder (HD; ICD-10) in children and adolescents in outpatient care in the period 1998-2001.
  
  
  METHODS
  
  
  
  METHODS
  18.75% random sample of a regional Statutory Health Insurance for the years 1998 until 2001 with n = 41,930 children and adolescents (1998: 0 to 15 years old). Children with HD were defined according to the wording of the diagnosis (1998, 1999) and the ICD 10-code: F90.0-F90.9 (2000, 2001).
  
  
  RESULTS
  Between 1998 and 2001 the percentage of children with a claims diagnosis of HD rose from 1.6% to 2.4% (administrative prevalence). The male to female ratio is about four to one (2001, boys: 3.8%; girls: 1.0%). The highest rate is seen in the age group of 7 to 10 years (2001, boys: 5.8%; girls: 1.4%). The diagnosis was documented by pediatricians in 54% of the children with HD, by GPs in 29% and by child and adolescent psychiatrists in 15%. Since 1998 child and adolescent psychiatrists became more important in the treatment of children with HD.
  
  
  CONCLUSIONS
  The data show an increase of the administrative prevalence of hyperkinetic disorder. The estimates are within the lower range of the prevalences gained by representative population-based field studies.
