Evaluation of the Nursing Outcomes Classification (NOC)--from theory to practice in Israel.

A study was undertaken on the use of the Nursing Outcomes Classification (NOC) in different practice settings in Israel that included an analysis of problems that can arise in using NOC and a proposed solution. The results indicated four main problems with using the NOC in nursing practice: It is not possible to build from several indicators a weighted index for estimating patient outcomes; some of the indicators are not identical to the clinical guidelines; the grading scales depend largely on subjective judgment; and we question whether an evaluation scale of 5 grades is necessary for such numerical values as vital signs. We suggest dividing the NOC into three main categories (based on original values, objective values as suggested in the clinical guidelines, and values that require the development of quantitative indices) to enable better implementation.
