title: An evaluator's perspective.
abstract: The importance of differentiating between evaluation (an overview of nursing care) and research (a biopsy of nursing care) is stressed. Evaluations are designed to influence nursing care; research is not. In evaluations, feedback is ongoing and dynamic; in research, variables are controlled for change. Magnitude of occurrence and amenability should determine priority of problem selection.
