Abstract
Randomized trials are often considered a poor method for study of cancer nursing issues because of the positivist approach of this method and the size and scale required for experimental studies. However, this method of research is highly valued in health-care evaluations and can provide detailed information on treatment or intervention comparisons. As many cancer nursing interventions are untested it is important that we are able to utilize research methods appropriately to identify care that is of benefit to patients. This article explores some of the advantages and difficulties that can be encountered when undertaking a randomized trial and reflects on the practical implications that such a method can entail. Radiotherapy nursing and interventions for radiotherapy side effects are an area that has been long neglected by researchers. The care of patients and the monitoring for side effects often reflect tradition rather than evidence-based practice. Which health care practitioner should take responsibility for that care or have the necessary skill for managing patient problems is rarely questioned. A randomized trial was used as a method to evaluate the effectiveness of a nursing intervention in comparison to that of conventional medical care. The advantages and disadvantages of this research approach are explored although data are not explored in depth. © 1999 Harcourt Publishers Ltd.
