Simplifying the complexity surrounding ICU work processes - Identifying the scope for information management in ICU settings

A multi-site study, conducted in two English and two Danish intensive care units, investigates the complexity of work processes in intensive care, and the implications of this complexity for information management with regards to clinical information systems. Data were collected via observations, shadowing of clinical staff, interviews and questionnaires. The construction of role activity diagrams enabled the capture of critical care work processes. Upon analysing these diagrams, it was found that intensive care work processes consist of 'simplified-complexity', these processes are changed with the introduction of information systems for the everyday use and management of all clinical information. The prevailing notion of complexity surrounding critical care clinical work processes was refuted and found to be misleading; in reality, it is not the work processes that cause the complexity, the complexity is rooted in the way in which clinical information is used and managed. This study emphasises that the potential for clinical information systems that consider integrating all clinical information requirements is not only immense but also very plausible.
