title: [Four year's experience with quality assurance in anesthesiology in Hamburg].
abstract: OBJECTIVE
  Since 1992 421,851 anaesthesias were documented by 39 institutes with a standard dataset issued by the German Society of Anaesthesiology and Intensive Care (DGAI). The project was run by the Association for Quality Assurance (EQS) in Hamburg. Some results of the evaluation of this datapool are presented questioning the feasibility of the project to support improvement processes within the participating institutions and which adjustments should be done considering these experiences.
  
  
  METHODS
  Data from machine-readable protocols and documentation software representing all anaesthesia cases were recorded since 1992 in a pilot project and since 1994 compulsory with a standard dataset issued by the DGAI. Comparing statistics of these data was produced at the EQS project office. In the steering committee and in meetings of the project participants the contents, policy and results of the project office. In the steering committee and in meetings of the project were critically analysed and adjustments initiated whenever necessary. Validity of data and feasibility of the method used was also questioned on the background of comparable studies.
  
  
  RESULTS
  With an incidence of 14.1% of all anaesthesias with special occurrences (AVB) the results are in the same range if compared with most other studies. However, documentation of data is not complete. This is assumed to be due to the large size of the dataset with 112 items and the additional workload associated with it. Nevertheless the participants mostly consider the project to be a very useful support for internal improvement projects.
  
  
  CONCLUSIONS
  The project method used so far is not mature yet. The data set must be streamlined and rendered more concise, quality indicators should be defined and tested, and the availability of statistically proven limits of tolerance should be the immediate aims in the further development of the project.
