Abstract: Methods and systems that facilitate rapid response to critical changes in a patient's condition. The disclosed techniques and structures may facilitate rapid input of data (e.g., observed conditions) by a nurse or other clinician, and may provide clinical decision support information based on the input data. In some cases, a user interface that dynamically updates a list of possible causes (e.g., medical conditions) in response to each received input may be provided. In some cases, a user interface presents input selection controls in a check list-type format, and allows a nurse to answer all, or only a subset, of the input selections, in any order.
