On-demand" information has been chosen by clinicians as one of their preferred modes of interaction with computers when in need of information about evidence-based practices. However, most of the clinicians' information needs remain unmet, especially due to a lack of easy access to resources that are able to satisfy these needs in a timely manner. We present three scenarios indicating opportunities for a clinical information system to present interdisciplinary standards at the point-of-care. In each scenario, we highlight the importance of context of use and the opportunities offered by the clinical workflow for providing access to relevant "on-demand" information. We also present an XML model for structuring non-physician interdisciplinary standards, in an effort to fulfill the requirements exposed by the three scenarios.
