Clinical workflow and its effect on data recorded for each alert. Orders are typically placed in batches and signed in one operation. Alerts fire at the time of signing. This diagram indicates how user actions are reflected in the data about the alert. Alert status is recorded as one of five categories in the system; (1) filtered (user is not automatically shown the alert), (2) removed, (3) cancelled, (4) overridden, or (5) viewed (typically a nursing action and not part of the prescribing process).
