Although there has been research investigating patient mortality as an outcome, there has been little discussion about models or theories of nursing-related determinants of mortality for hospitalized patients. Yet, unnecessary patient mortality is an important patient safety outcome. This article describes development of beginning theory of determinants of patient mortality culminating with a revised mortality model. Conclusions are made related to plans for further testing and refinement of the revised mortality model. Further, the utility of the proposed model in practice is discussed. © 2005 Lippincott Williams & Wilkins, Inc.
