A novel approach to ICU data visualization and communication integration
The intensive care unit (ICU) is a highly complex environment that houses critically ill patients requiring constant monitoring and care, as well as vast amounts of time-oriented data disseminated through a range of health information technologies (HIT), e.g., bedside and clinical decision support systems. Studies show the occurrence of medical mishaps due to diagnostic errors, impacting patient safety in spite of advances in HIT. Available visual representations of data, although time-oriented and multivariate, lack contextual information for communication among the ICU intensivists. We present a medical data visualization system (MIVA) that delivers multivariate data via a visualization display. The system organizes data into controllable time resolutions, providing contextual knowledge and communication tools at point-of-care. When comparing MIVA to paper charts, findings from two studies suggest that MIVA enabled significantly greater speed and accuracy during an in-lab experime...

A decade of emerging bedside information-visualization devices and clinical decision-support systems has provided intensive care unit (ICU) clinicians with a range of tools that display and intelligently filter data in ways that support patient diagnosis. There is an absence, however, of research that adequately addresses the need for visualization tools (related to context-sensitive information) that can reduce cognitive strain during decision-making. In response to this issue, Medical Information Visualization Assistant (MIVA) was designed to contextually organize patient longitudinal data with visual-enhancing tools for easy, rapid and more accurate analysis/interpretation of real-time patient data. MIVA was envisioned as an electronic medical record (EMR) visualization dashboard to reduce cognitive load and related diagnostic error. The current design phase will include communication tools to enhance MIVA's capacity to support ICU team collaboration. In this paper we describ...
