The development of evidence-based nursing¶ This paper argues that the current conception of evidence-based medicine has its limitations in the promotion of research which effects the quality of service in any health care system. It also poses something of a difficulty for the development of evidence-based nursing in particular. This paper advocates the more broad based concept of evidence-based practice and discusses its potential for addressing theory/practice problems and the uptake of nursing research. The broader conceptualization of evidence-based practice focuses on the integration of available evidence and the tacit knowledge of the investigator. An evidence-based practice project undertaken in Hong Kong is outlined as this provided the basis of many of the conclusions made in this paper. Three vignettes are given in order to demonstrate the nature of the evidence-based practice projects which have been conducted. The critical elements of evidence-based practice projects are outlined. Finally issues concerning the process of generating evidence, the relationship to continuous quality improvement and the cost effectiveness of evidence-based practice are discussed in more detail.
