An urgent notice generated by a computerized clinical decision support system (CDSS). These are usually in the form of a just-in-time, patient-specific message directed to one or more clinicians. It may be a warning regarding a clinician’s documented action (or lack thereof) or a documented decision. Or it may be an urgent informational notification of a new clinical condition, circumstance, or change in patient status that requires immediate attention. Some alerts require a response before the clinician can continue.
