Using online analytical processing to manage emergency department operations.
The emergency department (ED) is a unique setting in which to explore and evaluate the utility of information technology to improve health care operations. A potentially useful software tool in managing this complex environment is online analytical processing (OLAP). An OLAP system has the ability to provide managers, providers, and researchers with the necessary information to make decisions quickly and effectively by allowing them to examine patterns and trends in operations and patient flow. ⋯ It allows the user to form a comprehensive picture of the ED from both system-wide and patient-specific perspectives and to interactively view the data using an approach that meets his or her needs. This article describes OLAP software tools and provides examples of potential OLAP applications for care improvement projects, primarily from the perspective of the ED. While OLAP is clearly a helpful tool in the ED, it is far more useful when integrated into the larger continuum of health information systems across a hospital or health care delivery system.

Review Comparative Study
Disparate systems, disparate data: integration, interfaces, and standards in emergency medicine information technology.
As part of the broader informatics consensus initiative sponsored by Academic Emergency Medicine, this report addresses the issues of integration, interfaces, and data standards and how they are relevant to information management in emergency medicine. The purpose of this report, and the workgroup that contributed to its content, is to provide emergency physicians and other stakeholders in the emergency informatics community a sense of direction as they design, build, and/or choose systems. Problems are identified, strategies to address these problems are discussed, and consensus recommendations are provided.

Information technology and emergency medical care during disasters.
Disaster response to mass-casualty incidents represents one of the greatest challenges to a community's emergency response system. Rescuers, field medical personnel, and regional emergency departments and hospitals must often provide care to large numbers of casualties in a setting of limited resources, inadequate communication, misinformation, damaged infrastructure, and great personal risk. ⋯ In particular, next-generation wireless Internet and geopositioning technologies may have the greatest impact on improving communications, information management, and overall disaster response and emergency medical care. These technologies have applications in terms of enhancing mass-casualty field care, provider safety, field incident command, resource management, informatics support, and regional emergency department and hospital care of disaster victims.

Discrete event simulation of emergency department activity: a platform for system-level operations research.
This article explores the potential of discrete event simulation (DES) methods to advance system-level investigation of emergency department (ED) operations. To this end, the authors describe the development and operation of Emergency Department SIMulation (EDSIM), a new platform for computer simulation of ED activity at a Level 1 trauma center. The authors also demonstrate one potential application of EDSIM by using simulated ED activity to compare two patient triage methods. ⋯ The EDSIM model provides a flexible platform for studying ED operations as they relate to average treatment times for ED patients, but the model will require further refinement to predict individual patient times. A comparative study of triage methods suggests that ART provides a mix of benefits and drawbacks, but further investigation will be required to substantiate these preliminary findings.
