Development of computer-assisted patient control for use in the hospital setting during mass casualty incidents

Hospital resolution of mass casualty incidents can have difficulties involving "command and control" and information management, ineffective use of triage classes, and missed diagnostic procedures, leading to lower quality of care. A computer system has been developed to supply continuously updated group and patient data. The system uses barcoded identifiers to represent patients, injuries, facilities, and locations, in order to minimize errors and make exchange of data possible. The system communicates with the permanent hospital information system. This article reports the use of this technology during several experiments and real incidents. Computer registration based on bar codes, despite the greater number of items entered, still showed 25% fewer inaccuracies when compared with handwritten medical charts. Extensive training was shown to be unnecessary. Paramedical personnel judged the automated procedures to be an improvement during the admission of 143 evacuated patients.
