Abstract: This paper uses the findings of two studies to explore the nature of nurses' practice when working with vulnerable and marginalised populations, particularly with regard to the attributes of holism and individualised care. The first study was with the elderly with delirium and used a critical gerontological methodology informed by postmodernism and Foucault's understanding of discourse. The other study with indigenous Maori women utilised Glaserian grounded theory informed by a Maori-centred methodology. The findings show that a problem focussed approach to health care is offered to patients that does not incorporate individual health experiences. In addition, the social context integral to people's lives outside of the health care environment is ignored. Consequently, the foundations of nursing practice, that of holism, is found to be merely a rhetorical construct.
