A Clinical Information System (CIS) is a computer-based system that collects, stores, and provides access to clinical information for healthcare delivery. A CIS includes features like electronic medical records, clinical data repositories, order entry, and decision support. Key stakeholders in selecting and implementing a CIS include clinical staff, administrative staff, and information technology staff. Implementing a CIS requires significant costs for equipment, IT support, training, and maintenance. Ongoing education is also needed to ensure staff can properly use and adapt to changes in the system.
