Abstract
Title. The use of theory in qualitative approaches to research: application in end-of-life studies. Aim.

Within the reviewed end-of-life studies, the use of theory included theory creation or provision of a comparative framework for data analysis and interpretation. Implications for nursing. Nurses who
