Following the trail: understanding information flow in the emergency department

Abstract

A hospital emergency department (ED) is a complex cognitive work system. ED providers routinely create, process and share various kinds of information in their work. They may constantly transform information using technological artifacts such as an electronic patient information system. The functionality in the technology, however, limits their tasks and activities. So, they create their own artifacts (such as handwritten notes on a post-it note), to share and process information. The goal of the paper is to illustrate how health providers in EDs create, process, transform and share information to achieve work goals. We present the information trail model in the ED to illustrate various facets of information creation activity and generate insights for health information technology design.
