title: Textual content, health problems and diagnostic codes in electronic patient records in general practice.
abstract: OBJECTIVE
  To investigate textual content, health problems and diagnostic codes in everyday electronic patient records.
  
  
  METHODS
  Retrospective and observational database study.
  
  
  METHODS
  Primary health care in Stockholm.
  
  
  METHODS
  Twenty randomly selected general practitioners with 20 records each.
  
  
  METHODS
  The frequency of use of problem-oriented medical records. The number of words, problems and diagnostic codes. The completeness and correctness of the diagnostic codes.
  
  
  RESULTS
  About 14.5% of 400 studied records were problem-oriented. The mean number of words per record was 99.4, and the mean number of problems managed per record was 1.2. On average, there were 1.1 diagnostic codes per record and this differed widely among GPs and also among the electronic patient record systems. The mean number of codes per problem was 0.9, and the proportion of correct codes was 97.4%.
  
  
  CONCLUSIONS
  The electronic patient records in general practice in Stockholm have an extensive textual content. A vast majority of the problems are coded and the completeness and correctness of diagnostic codes are high. It seems that problem-oriented electronic patient record systems enforce coding activities. It is feasible to establish a database of diagnostic data for research and health care planning based on electronic patient records.
