title: Structured classification for ED presenting complaints - from free text field-based approach to ICPC-2 ED application.
abstract: BACKGROUND
  Although there is a major need to record and analyse presenting complaints in emergency departments (EDs), no international standard exists. The aim of the present study was to produce structured complaint classification suitable for ED use and to implement it in practice. The structured classification evolved from a study of free text fields and ICPC-2 classification.
  
  
  METHODS
  Presenting complaints in a free text field of ED admissions during a one-year period (n=40610) were analyzed and summarized to 70 presenting complaint groups. The results were compared to ICPC-2 based complaints collected in another ED. An expert panel reviewed the results and produced an ED application of ICPC-2 classification. This study implemented the new classification into an ED.
  
  
  RESULTS
  The presenting complaints summarized from free text fields and those from ICPC-2 categories were remarkably similar. However, the ICPC-2 classification was too broad for ED; an adapted version was needed. The newly developed classification includes 89 presenting complaints and ED staff found it easy to use.
  
  
  CONCLUSIONS
  ICPC-2 classification can be adapted for ED use. The authors suggest a list of 89 presenting complaints for use in EDs adult patients.
