Outcomes research (a subset of health services research) is undertaken to document the quality and effectiveness of health care and nursing services. Process analyses describe the process by which a program gets implemented and how it functions in practice. Impact analyses test whether an intervention caused any net impacts relative to the counterfactual. In methodologic research, the investigator is concerned with the development, validation, and assessment of methodologic tools or strategies.
