Determining variables to measure the impact of information systems on nursing practice

Evaluations of nursing information systems (NIS) are complex. Current research and evaluative results on the impact of computer technology and information systems (IS) in nursing practice have been mixed. Clear cost and performance benefits have not been documented, because the variables and indicators of these gains are not well identified. The purpose of this discussion is to present a conceptual framework of the nursing practice and to group and organize specific variables, or indicators.
