INTRODUCTION The definition of nursing informatics outlined by Staggers & Thompson in 2002 defines nursing informatics as a combination of informatics, information science and design science nursing to assist in the management and processing of nursing data information and knowledge to support nursing practice and patient care delivery. This combination helps bring system information, nursing knowledge, clinical decision making, support and data to the nursing field, whereby patient needs are translated into IT programs so that all members of the healthcare team have access to the necessary information when it is It is necessary, in this way, to make the healthcare system more effective, efficient and less time-consuming and to improve the productivity of nursing care. HISTORY Before the intervention of the modern computerized technological system, access to information was through books, telephone, field trips and person to person. requests. This information has been stored through the filling system which is time consuming and can be easily lost. The information was then made available to other healthcare providers through search and find in the filler cabinet coded by individual identification numbers and/or color. There was a big drawback to this system, people who did not have the right to access these files sometimes accessed them for personal reasons and then the same files were lost. CHANGE IN THE SYSTEM Due to the introduction of science, the healthcare system has changed from manual to computerized system. Technology has become such an integrated artifact of patient care that current patient care literature often highlights computers and other modern devices as nursing tools, which are used and controlled by healthcare providers for the sole purpose of providing care. more effective for patients. our patients. Manual procedures are replaced by the use of computerized devices. DEVELOPMENTS Since the development of the computer system and the Internet, there has been a great improvement in the accessibility of data and the security, availability and accessibility of patient information. It is no longer necessary to carry around large stacks of files to obtain the patient's medical history, it can be easily obtained on the patient's medical record on the computer minimizing the paper files available to work with, another advantage is that the research can be performed in the comfort of your home because almost every home and every individual has a computer and because it is so easy and convenient to use, many people, such as nurses and the public, surf the Internet to obtain information, to improve their knowledge.
