PurposeIn 1994, the Department of Anaesthesiology and Intensive Care Medicine of the Justus Liebig University at Giessen decided to install an Anaesthesia Information Management System (AIMS). Individual aspects and results from routine operation are presented, demonstrating the quality of the documentation and the value of information at the anaesthesiological workstation. The paper discusses which adaptations are necessary according to the experience gathered.MethodsFor the installation of the system Apple Macintosh Clients (Apple Computer, Inc., Cupertino, California) and a File Server were integrated into the partially existing hospital network. The hospital network had to be enlarged during the project according to the Anaesthesiological requirements. The software of the Hospital Information System (HIS) and an HTML browser were installed at individual workstation computers in addition to the Anaesthesia documentation software NarkoData (ProLogic GmbH, Erkrath). The remote control software Timbuktu (Farallon, Alameda, USA) has been added to facilitate remote administration. The file administration programme FileWave (Wave Research, Berkeley, USA) is used for file distribution. Since 1995, all anaesthesia procedures have been documented with the system, either by online or postoperative recording. Since 1997, the recorded information has been stored in a relational Oracle 7 data bank (Oracle Corporation).ResultsFrom 1995 to 1997, 60,405 anaesthesiological procedures have been recorded with the help of this AIMS at 111 decentralised workstations. In 1997, 87.8% of the 21,130 performed anaesthesia procedures have been recorded online with the system and 12.2% postoperatively. From 1995 to 1997, the number of recorded procedures increased by 6.4% from 19,854 to 21,130. Because of lacking interfaces at some patient monitoring stations, the automatic recording of patient data could only be implemented at 69 workstations (62%). With the corresponding access rights, important patient information from the HIS (diagnoses, laboratory results, etc.), records of previous Anaesthesia procedures, numerous statistics, and the whole information from the hospital's intranet (including e-mail) are available at the anaesthesiological workstation at any time.ConclusionThe implementation of the AIMS and an effective user support have been able to increase significantly the quality of documentation, the flow of information at the anaesthesia workplace and the number of recorded Anaesthesia procedures. All recorded data can be analysed immediately The expansion of the automatic data transfer from the patient monitoring, interfaces to other computer subsystems of the hospital and a practicable evaluation programme are necessary for further enhancing the efficiency of the AIMS.
