Implementing an animated geographic information system |
Geographic information system (GIS) technology provides the potential to integrate and analyze multiple data sources in spatial and temporal context and rapidly produce composite images. Although GIS technology continues to grow as an important tool in public health and spatial epidemiologic applications,4-6 few studies have explored the utility of GIS echnology in nosocomial infection outbreak detection and analysis.
We hypothesized that animated GIS technology would be a useful tool to both visualize patterns of nosocomial transmission and potentially determine environmental factors contributing to the spread of resistant organisms in the hospital. In this paper, we describe a prototype system to capture staff movement and nosocomial infection data and present these data in an intuitively visual format to highlight clearly the factors known to contribute to nosocomial infections.
