Background
Although health disparities are well documented, the extent to which they affect end of life care is unknown. Limited research funding leads to sparse and often contradictory palliative care literature, with few studies on causal mechanisms.
Purpose
The purpose of this article is to explore the psychosocial, cultural and spiritual health disparities existing in palliative and end of life care with the goal of identifying future research needs.
Method
To determine knowledge gaps related to health disparities in psychosocial, cultural, and spiritual aspects of end of life care we draw upon recent literature from multiple databases.
Discussion
Although there are few data, we do know minorities make little use of hospice, often because of lack of knowledge about hospice or palliative care, family-centered cultures, and preferences for more aggressive end of life care than hospice allows.
Conclusion
Future research should include a search for theoretical and causal mechanisms; prospective longitudinal investigations; diverse patients, conditions, contexts, and settings; methodological diversity and rigor; and interdisciplinary, culturally sensitive interventions.
