The definition of Nursing Informatics as outlined by Staggers & Thompson in 2002 defined Nursing Informatics as a combination of computer science, information science and nursing science design to assist in the management and processing of nursing data information and knowledge to support the practice of nursing and the delivery of patient care. This combination helps to bring system information, nursing knowledge, clinical decision making and support and data into the nursing field, whereby the needs of patients are translated into computer programs so that all members of the health care team will have access to the necessary information when it is required thus resulting into a more effective, efficient and less time consuming health care system and enhancing the productivity of nursing care.
Before the intervention of the modern computerized technology system, information was access through books, telephone, field trips and person to person enquiries. These information, were stored through the filling system which takes a long time and can easily be misplaced. The information was then made available to other health care professional through search and find in the filling cabinet coded by individual identification numbers and or by colors. There was a big disadvantage to this system, individuals who did not have the right to access these files sometimes access them for their own personal reasons and then the same files went missing.
