Clinical Decision Support System

A system (computer or otherwise) intended to provider CDS to clinicians, caregivers and healthcare consumers. Automated CDSS are usually just-in-time, point-of-care messages in the form of an alert, reminder, recommendation, or informational notification regarding a patient. Automated CDS systems typically include a knowledge base (which contains stored facts and some method of algorithmic logic), and event monitor (to detect data entry or the storage of data from a laboratory or other system), and a communication system to the end user (unidirectional or bidirectional).
