Interprofessional relations between doctors and nurses: perspectives from South Wales This paper discusses findings from a study of interprofessional relationships between doctors and nurses in medical wards in three provincial general hospitals in south Wales. The aim of the research was to investigate the changing nature of doctor-nurse relations, and in particular, how far the notion of the doctor-nurse game, as developed by Leonard Stein (Stein 1967, 1990), remains relevant to contemporary hospital work. The present paper concentrates on a subset of the findings concerned with doctors' and nurses' accounts of the hospital division of labour and the extent of any overlap in their work activities. Semi-structured interviews were conducted with 20 doctors and 39 nurses in their places of work over a period of 4 months. Inductive analysis of the data indicated that, whilst doctors and nurses perceived their roles in largely traditional terms, there was some recognition of blurring of occupational boundaries, especially when considering work pressures, working at night and differences in practice in more specialized clinical areas. Although nurses were generally reluctant to challenge doctors' authority, some used the notion of patient 'advocacy' to frame and justify their questioning of particular decisions. Whilst doctors valued 'experience' in nurses and saw experienced nurses as the group who might most legitimately move into doctors' territory, nurses valued formal education and saw advanced nursing qualifications as the route to role expansion.
