The purposes of this national study were to determine: (a) a definition of nursing administration research and (b) priority nursing administration research questions. Brainstorming was used initially with Council on Graduate Education for Administration in Nursing (CGEAN) members in 1984, to delineate concepts for definitions. Definitions and research questions were generated and rated in a three-round Delphi survey by 129 experts from nursing and health administration. According to the most widely supported definition, nursing administration research is concerned with establishing costs of nursing care, examining the relationships between nursing services and quality patient care, and viewing problems of nursing service delivery within the broader context of policy analysis and delivery of health services. The research question of most importance was: What are the cost-effective components of clinical nursing care that yield high patient satisfaction, decrease the number of complications, and shorten hospital stay for identified groups of patients? In a scenario exercise at the 1985 CGEAN meeting, additional priorities identified were vulnerable populations and equity.
