The NHSBSP (2008b) guidelines stress that nursing care should be evidence-based and reviewed regularly to ensure that high standards of practice are achieved and maintained. clinical nurse specialists are responsible for evaluating their practice. There is agreement in the literature that the role of the clinical nurse specialists is poorly defined (Joneset al2010). This ambiguity, and the lack of statistical outcome data, make evaluating clinical nurse specialists’ practice difficult.Furthermore, time constraints and lack of staffing contribute to these difficulties.
