Patterns of nursing: a review of nursing in a large metropolitan hospital.

In this Clinical Practice Development (CPD) project we set out to identify and describe current approaches to the management and delivery of nursing care in an Australian Metropolitan Teaching Hospital. Using a simple descriptive design, data were collected to elicit patterns of care provided by nursing teams. We sought to demonstrate patterns described by nursing teams (interviews) and actual patterns of care (observation). As expected there was a degree of incongruence between the espoused and actual patterns of care. Interview data revealed that most study wards had a view of nursing that emphasizes meeting the total care needs of patients and their families through offering biopsychosocial and educative care. The observational data revealed that a relatively large proportion of time was expended on activities that were not regarded as important by staff when interviewed (e.g. documentation) while relatively small amounts of time were observed to be spent educating patients or communicating with relatives of patients. The identification of this type of gap creates a dissonance in clinicians that can be used to stimulate change through CPD. Clinicians used the information to stimulate discussion and to rewrite team value statements.

Multidisciplinary nursing: re-thinking role boundaries.

The ambiguous role of nurses within the health care team has been a subject of much debate, evident in current practice and the study of the early development of nursing in Australia. Early nursing work was broad and uncontested. Debates about nursing and 'non-nursing' tasks are thought to have emerged after the establishment of 'Nightingale reforms' in the 1870s. Nursing role conflicts may be due in part to the rise in technology and medical intervention, the demise of 'generalist' doctors, nurses and patient-centred care, the creation of nursing specialists who moved to other community care positions and nursing's drive for professionalization. Nurses' role in mealtimes provides one example of the ambiguous and contentious issue of nursing and non-nursing work. Health services need a generic worker who is client-focused, possesses multidisciplinary skills, manages the care environment, humanizes the system at the point of contact and acts therapeutically. This broad and flexible role ascribed to nurses is threatened by cost containment and the scramble for new occupations within the broad field of health services, which is plagued with increasingly rigid role boundaries. The examination of nursing workforce planning arrangements is needed to ensure greater coherence and clearer lines of nurses' roles and responsibilities.

Mealtimes in nursing homes. The role of nursing staff.

The literature suggests that food service largely has become identified as a non-nursing duty and as a task that should be completed as quickly as possible. This conflicts with the evidence that social interaction at mealtimes has the potential to promote well being. Using observational and interview techniques, the social and functional context of meal service in 10 nursing homes was examined in this study. The findings from the observation of and interviews with staff are reported in this article. Three broad themes describing the cultural practices of nursing home staff during mealtimes are identified as follows: maintaining personal identity, assisting individuals to eat, and maintaining interaction. Alongside residents' general outward acquiescence to the service, nurses did not see problems and deficiencies with the service observed by the researchers or reported by the residents. Recommendations to improve mealtime service in nursing homes have been put forward in an effort to enlighten staff.

Functional genomic analysis of phagocytosis and identification of a Drosophila receptor for E. coli.

The recognition and phagocytosis of microbes by macrophages is a principal aspect of innate immunity that is conserved from insects to humans. Drosophila melanogaster has circulating macrophages that phagocytose microbes similarly to mammalian macrophages, suggesting that insect macrophages can be used as a model to study cell-mediated innate immunity. We devised a double-stranded RNA interference-based screen in macrophage-like Drosophila S2 cells, and have defined 34 gene products involved in phagocytosis. These include proteins that participate in haemocyte development, vesicle transport, actin cytoskeleton regulation and a cell surface receptor. This receptor, Peptidoglycan recognition protein LC (PGRP-LC), is involved in phagocytosis of Gram-negative but not Gram-positive bacteria. Drosophila humoral immunity also distinguishes between Gram-negative and Gram-positive bacteria through the Imd and Toll pathways, respectively; however, a receptor for the Imd pathway has not been identified. Here we show that PGRP-LC is important for antibacterial peptide synthesis induced by Escherichia coli both in vitro and in vivo. Furthermore, totem mutants, which fail to express PGRP-LC, are susceptible to Gram-negative (E. coli), but not Gram-positive, bacterial infection. Our results demonstrate that PGRP-LC is an essential component for recognition and signalling of Gram-negative bacteria. Furthermore, this functional genomic approach is likely to have applications beyond phagocytosis.

Nurses' views on competency indicators for Australian nursing.

This paper reports on a project commissioned by the Australian Nursing Council Inc that sought to develop an approach to the maintenance of continuing competence in nursing broadly acceptable to nurses in all states and territories. This project involved extensive consultation with nurses, consumers and key stakeholders on appropriate competence indicators. Findings suggest that a majority of nurses support the development of competence indicators but most are confused about the nature of competence.

Continuing competence and the regulation of nursing practice.

A study commissioned by the Australian Nursing Council Inc. sought to develop an approach to the maintenance of continuing competence in nursing that is broadly acceptable to nurses in all States and Territories. The study involved a comprehensive review of the international literature and this paper provides an overview of statutory regulation of professions with particular reference to regulation of the nursing profession. A definition of competence and competencies and a discussion of beginning and continuing professional competence are presented, followed by a review of current indicators of continuing professional competence used by a variety of professions in Australia.
