This article presents an overview of a literature review on how prone positioning can alleviate pathophysiological changes in ARDS and improve ventilation and perfusion. Improvement of gas exchange, efficiency of oxygenation and lung function are emphasized. Literature on the pathophysiology of ARDS, and the physiological effects of prone positioning on haemodynamics and lung function is examined. ⋯ There are also contraindications in rotating between the supine and prone positions. Nevertheless, by rotating patients with ARDS, it is possible to achieve a significant improvement in A-aDO2, decrease shunting, and therefore improve oxygenation without use of expensive, invasive and experimental procedures. Placing patients with ARDS in the prone position can reduce inspiratory oxygen concentrations and peak inspiratory pressures, which minimizes the chance for barotrauma and the iatrogenic effects of hyperventilation oxygen toxicity.

This is the first of two linked papers exploring decision making in nursing which integrate research evidence from different clinical and academic disciplines. Currently there are many decision-making theories, each with their own distinctive concepts and terminology, and there is a tendency for separate disciplines to view their own decision-making processes as unique. Identifying good nursing decisions and where improvements can be made is therefore problematic, and this can undermine clinical and organizational effectiveness, as well as nurses' professional status. ⋯ An alternative approach based on a general model of classification is then presented in detail to introduce its terminology and the unifying framework for interpreting all types of decisions. The classification model is used to provide the context for relating alternative philosophical approaches and to define decision-making activities common to all clinical domains. This may benefit nurses by improving multidisciplinary collaboration and weakening clinical elitism.

Grade mix within the district nursing team in the United Kingdom has changed markedly over the last 10 years but the relationship between grade mix and skill mix has received only intermittent research attention. This study adopted an ethnographic approach and aimed to explore the way in which grade and skill are taken into account in the delegation of nursing care. ⋯ The developing role of nursing auxiliaries is discussed in relation to the role of the G grade sister, resource constraints and the standards of patient care. The paper concludes by arguing that the supervision and leadership role provided by the G grade sister should be fully recognized and safeguarded.

The purpose of this investigation was to compare anxiety and depression in Taiwanese cancer patients with and without pain. In 1998, a convenience sample of 203 hospitalized cancer patients, 77 with pain and 126 without pain, were assessed for anxiety and depression using the Hospital Anxiety and Depression Scale (HADS). Disease-related factors such as performance status, disease stage and perceived treatment effect were also assessed and controlled for their effect on anxiety and depression. ⋯ Patients with pain had more depressive symptoms than patients without pain. Cancer patients' anxiety can be predicted significantly by functional status and perceived treatment effect. In addition to pain status, cancer patients' depression can be predicted by their functional status.
