Technology and Decision Making
Technology, decision-making processes, and data accessibility have changed dramatically in recent years. This paper will discuss systems and informatics theories. The paper will confer on the Data, Information, and Knowledge (DIK) Model. The role of expert system in nursing care and medicine will be provided. Decision aids and decision support systems are used everyday providing focus, leadership and direction within technology and will be examined. The use of technology for patient and client management will be explored. An analysis of the …show more content…

“Information consists of data, but data is not necessarily information. Also, wisdom is knowledge, which in turn is information, which in turn is data, but, for example, knowledge is not necessarily wisdom. So wisdom is a subset of knowledge, which is a subset of information, which is a subset of data” (Steyn, 2001, para. 2). Without an understanding of the source of data and information which is based on activities and situations, the relationship between data, information, and knowledge will not be understood (Liew, 2007).
Expert Systems in Nursing Care and Medicine Medical artificial intelligence is primarily concerned with the structure of Artificial Intelligence (AI) programs that perform diagnosis and make therapy recommendations. ‘Unlike medical applications based on other programming methods, such as purely statistical and probabilistic methods, medical AI programs are based on symbolic models, such as statistical and probabilistic methods, medical AI programs are based on symbolic models of disease entities and their relationship to patient factors and clinical manifestations’ as defined by Clancey and Shortliffe (1984).
Expert systems (ES) in nursing care and medicine fill an appropriate role with intelligent programs offering significant benefits. They hold medical knowledge containing specifically defined tasks and are able to reason with data from
