This article explores the application of Lipsky's (1980) notion of street-level bureaucracy for nursing staff. This article aims to demonstrate the importance of discretion within the day-to-day work of front-line nursing staff, which is similar to that of other public-sector workers. The findings are from an exploratory case study based within a Scottish inner-city hospital. It specifically focuses on how nurses can be seen to be street-level bureaucrats and how front-line nursing staff interpret policy. Discretion can be seen to be a significant feature within the front-line practice of nursing staff and this may have implications for the implementation of health policy.
