title: Potential benefits of Anaesthesia Information Management Systems for multicentre data evaluation: risk calculation of inotropic support in patients undergoing cardiac surgery.
abstract: OBJECTIVE
  The aim of this study was to test the hypothesis whether it is easily possible to transfer and apply the methods of data extraction and analysis of a performed study to a data pool of a different medical centre using the same type of Anaesthesia Information Management System (AIMS). For this purpose the objective of a study in cardiac anaesthesia, investigated at the University Hospital Giessen, was applied to the data pool of the Heart Centre Siegburg.
  
  
  METHODS
  The Giessen study evaluated factors related to the use of positive inotropic drugs (PIDs) in adults undergoing elective cardiac surgery with cardiopulmonary bypass (CPB). The same objective and methods were applied to data of 1672 patients of the Heart Centre Siegburg. In both centres anaesthetic procedures were recorded with the AIMS NarkoData. Existing database queries were adapted according to the Siegburg database configuration for detection of patients having received PIDs during or after weaning from CPB.
  
  
  RESULTS
  It was revealed that data from the Siegburg database using the same data model and configuration, were identical to the Giessen database except for a few items only. Thus database queries of the Giessen study could be applied to the new data pool requiring no considerable additional input.
  
  
  CONCLUSIONS
  We could demonstrate that multicentre data analysis in anaesthesia using AIM systems can be carried out successfully. Once the methods of data extraction and analysis are established they can be transferred to data pools of different centres without requiring additional time, personnel and material resources.
