Health Informatics (also called healthcare informatics, medical informatics, nursing informatics, clinical informatics, or biomedical informatics) is informatics in health care. It is a multidisciplinary field that uses health information technology (HIT) to improve health care via any combination of higher quality, higher efficiency (spurring lower cost and thus greater availability), and new opportunities. The disciplines involved include information science, computer science, social science, behavioral science, management science, and others.
