Nursing effectiveness reconsidered: Some fundamental reflections on the nature of nursing

Abstract Despite being considered the proverbial backbone of our healthcare systems, nursing still seems to struggle to scientifically demonstrate its contribution to care experiences and patient outcomes. This leads to erosive tendencies that threaten the development of the profession and its progress as an academic discipline. With this paper, we want to contribute to the theoretical discourse concerning the nature of nursing and the research into its effectiveness. We begin by outlining a set of prevailing paradoxes and their consequences relating to nursing and nursing research: the issue of demonstrating its unique contribution despite a clear societal mandate; a discrepancy between subjectively experienced effectiveness and objectively ascertainable effectiveness; and a mismatch between theoretical premises of nursing and task‐oriented cultures in practice environments. Using an example of a seemingly simple nursing intervention, we intend to demonstrate the qualities and complexities of nursing. We further illustrate this by drawing on several of our research projects using theory‐based evaluation methodologies. From these illustrative examples, we distil two insights relating to nursing interventions that we consider fundamental: the nurse, as a person, is central to its unique effectiveness; and there is always an interplay between context, intervention and its intended effect. We summarise our considerations and argue the case for conceiving research designs in alignment with theoretical premises of nursing.
