The overarching goal of this project is to develop engineering requirements for future information resources in the ICU. We describe a method and related instrumentation for collecting data about information requirements from a clinical team in situ. Video records are collected using three consumer-grade video cameras, augmented by a wireless microphone system. We combine the video/audio recordings into a single, synchronized record. A transcript is prepared, and then coded by a professional medical records coder, using the SNOMED CT coding scheme. The resulting record represents a coded stream of verbal utterances that is sufficiently precise to support systems engineering analysis.
