It has been nearly four decades since nurses began working in informatics, and nursing informatics has been recognized as a specialization in nursing resources since 1984. There have been many additions to the field over the years, including data recovery, ethics, patient care, decision support systems, human-computer interaction, information systems, imaging informatics, computer science, information science, security, electronic patient records, intelligent systems, e-learning, and telenursing.
As defined by Hana in 1985, Nursing Informatics involves the application of information technology to nursing duties such as education, management, and practice. Graves and Corcoran in 1989 defined it as the integration of information science, computer science, and nursing science to support nursing practice and knowledge management. In 1994-1995, the American Nurses Association (ANA) published its aim and standards and introduced Nursing Informatics as a specialty that integrates nursing science, computer and information science to provide data management, knowledge and nursing care.
