Towards a reference model for representing nursing information needs.

Information needs studies in clinical settings often face the problem of integrating and analyzing data collected using different study tools. Generally, a coding taxonomy or a model is developed to capture and code the study data. Significant efforts are required to develop a model that not only captures the study data but is also closer to the clinical domain to draw meaningful real world inferences. Further, a study-specific model limits comparative evaluation of studies across different institutions. In this paper, we propose a reference model for representing nursing information needs. We use an iterative and collaborative approach in representing the concepts in the model. The model consists of 33 information (need) concepts, 29 information sources and 7 categories of nursing tasks which were used to code 228 identified information need instances.

Using a context-aware medical application to address information needs for extubation decisions.

Information overload has been one of the causes of preventable medical errors [1] and escalating costs [2]. A context-aware application with embedded clinical knowledge is proposed to provide practitioners with the appropriate amount of information and content. We developed a prototype of a context-aware medical application to address clinicians' information needs that arise in a data intensive unit, the Cardio-Thoracic Intensive Care Unit (CTICU). A major clinical decision supported by the prototype, the extubation decision, is illustrated.
