The Incidence of Artifacts in the Anesthesia Information Management System Database.

To Evaluate the Incidence of Artifacts in the Locally Developed AIMS Database.

The purpose of the study is to evaluate the incidence of artifacts in the developed AIMS database

At first, the authors evaluated the accuracy of the traditional, manually completed paper-based documentation, which sets a benchmark for the accuracy that the electronic documentation and database provides.

At the second portion, the investigators used the paper-based documentation as a standard to compare the electronic documentation. The incidence of artifact was double checked by two investigators.

At the third portion, the authors calculated the artifact incidence in the AIMS database, using paper based and electric document anesthesia records as the standard respectively.
