Should nurses be studying bioscience? A discussion paper.

The growth of bioscience knowledge over the last two decades has increased the potential benefits of scientifically based patient care by contributing to the theory of clinical care. However, there is little evidence that knowledge, derived from the human biosciences is being fully incorporated into nursing theory and practice. Nursing has developed its own unique professional body of knowledge, heavily influenced by behavioural science. If nursing theory leans towards behavioural science, but practice is devoted to problems of biological disturbance, nursing may be facing a widening theory-practice gap, greater than other professions. The theory-practice gap in nursing may be widened by the exclusion of bioscience from nursing theory. Nurses' relative disinterest in the natural sciences can be attributed both to sociological reasons and to problems stemming from the symbol-object dichotomy that recur in the teaching of natural sciences. Reflection on practice and examination of education method are suggested as strategies for re-introducing bioscience into nursing theory and practice. A challenge facing nurse educators is the integration of biological science into the nurses' conceptual ecologies. For, if nursing fails to make bioscience its own, much of the clinical welfare of patients will become a medical monopoly.
