This paper has identified three levels of vocabulary needs for nursing that are required and the technological advances that make integration possible. At the point of care, there will predictably be many nursing vocabularies and classifications used. At the network level of care, there will be several nursing classifications used. Because of technology breakthroughs such as the Web, XML, object-oriented technology, and relational databases, multiple classifications can continue to be used at the site of patient care and within varying health care systems. However, at the universal level, a unicode of a single taxonomy of nursing, with a single classification scheme will make data entry more simple, meaningful, and useful, data retrieval easier, international comparisons possible, and lower costs for data retrieval. In the end, it is anticipated that these efforts will facilitate the measurement and delivery of continuously improving care. Existing nursing structures that are already universally accepted may be the taxonomy to consider adopting at the universal level.
