This Conceptual Model for Nursing Information describes the core activities of nursing, the collection of information about these activities, and argues that these activities must be described using standardized nursing languages. Relevant literature, both national and international, was reviewed and summarized. A maximum data set for nursing was developed. In the United Kingdom, a new and radical approach to the process of nursing is required; one that demonstrates that nursing is the decision-making that takes place in all core activities of nursing. Unless nurses have a clear view of what the profession requires from technological solutions for the recording of nursing activities, less than optimal solutions will be forced upon the profession.
