Conceptual frameworks used in funded nursing health services research projects.

Theories not only suggest ideas for research, but they provide order and logic to an investigation and limit the number and type of variables to be considered to a reasonable few. Although relatively little health services research is done within nursing, there is a growing appreciation of the need for knowledge related to the use, costs, quality, delivery, organization, financing, and outcomes of health care and how nursing practice influences these variables. Conceptual frameworks used by investigators in funded grants from the Agency for Healthcare Research and Quality show that workforce-related health services research of nursing phenomena is based on a wide variety of conceptual models, many of the investigator's own invention. Ultimately, there may emerge new theories or conceptual frameworks that combine clinical, organizational, financial, and outcome variables from the unique perspective of nursing. Such conceptualizations will guide future researchers and add coherence to the body of health services research into nursing issues.
