Palliative care research: methodological and ethical challenges.
Nursing research in palliative care has, to date, been limited. As palliative care is increasingly recognized as a nursing specialty area, it requires the scientific foundation that research provides. Palliative care clients are particularly vulnerable because of the intensity of their illnesses and the emotional impact of impending death. This article identifies and discusses ethical and methodological challenges faced by those conducting research with this population. Suggestions for strategies that may help researchers meet these challenges are included.
