Current classification systems for nursing were investigated and their specifications were gathered in a questionnaire. The items were prioritized by experts in four degrees. Using statistical analysis items with a priority over 80 percent (average 2.4) were selected.

Results: Findings about nursing diagnosis, intervention and outcomes showed that diagnosis item (average 2.93 out of 3), intervention item (average 2.52 out of 3), and outcome item (average 2.84 out of 3) should be presented in the system.
