UnlabelledFrom January 1997 until June 1999, the complete durations of stay of 3152 outpatients were entered into a computerized documentation system. The scope of the data entry went from patient admission to patient release. The objective was to determine the usefulness of the anaesthesia information management system (AIMS) in producing complete and high-quality documentation in the field of outpatient operations. Some aspects and results from routine work are presented here.MethodThe system was installed in eight bedside computers, in addition to a further client connected to the existing AIMS via Ethernet. Patient medical courses were documented both preoperatively and postoperatively in outpatient bedsides until their discharge or admission. The online documentation software NarkoData (Version 4, Imeso GmbH, Hüttenberg, Germany) was used to document and store patient data in a database. This program contains all relevant information concerning the course of anaesthesia and outpatient duration of stay, including application of drugs, vital signs, observation times, and medical findings as well as the data sets of the German Society of Anaesthesiology and Intensive Care Medicine (DGAI), ICD, and ICPM. Data was analyzed by exporting from the database into a statistical program using "structured query language."ResultsData sets of 3152 outpatients were entered into the online documentation software. Most (54.2%) of the ambulatory surgical procedures were performed by the Department of Traumatology. General Surgery followed with 16.0%, and Urology managed 9.5% of the cases. The most frequent ambulatory surgical procedures were: diagnostic arthroscopy (923, 31.2%), removal of osteosynthetic material (410, 13.8%), and circumcision (250, 8.4%). Anesthesia procedures consisted of inhalative (38.6%, n = 1218) and intravenous anesthesia (IVA) (29.9%, n = 938). In 22.6% (713) of the cases, regional anaesthesia was performed. The average postoperative observation time was 289.2 +/- 140.1 minutes. One hundred sixty-nine patients (5.4%) were unexpectedly admitted to overnight care. The decision to admit patients to normal wards took place within the first 3 postoperative hours in 51.9% of the cases.ConclusionThe AIMS described above is sufficient in documenting the entire care process of patients in a day care unit. Integration into the existing AIMS was an important prerequisite for the integrity of the documentation chain. This allowed for a sensitive communication with other clinical data processing systems. The quality of documentation and flow of information at the workplaces in the day care unit were increased, similarly to other anaesthesiological workplaces in the hospital. Medical and administrative data and information for analyses of clinical processes are possible with such tools.
