In the UK the role of the nurse practitioner (NP) has been slower to develop than in the USA (Tye 1997). However, since its inception, studies of the role have found positive results in areas of patient satisfaction (Touche Ross 1994). James and Pyrgos (1989) reported 94% of patients suitable to seen by a NP would use a NP if introduced. A study by Freij et al. (1996) concluded that emergency NPs were as competent at interpreting X-rays as casualty officers. Despite such evidence, Meek et al. (1995) noted opposition to this new advanced practice from other disciplines who wished to maintain the ‘status quo’. In light of these findings, a study was undertaken to examine the new NP Service at Antrim Hospital, Northern Ireland. A patient satisfaction survey, a retrospective X-ray audit and a subjective assessment by other disciplines, were carried out in order to evaluate the service.
