SIGNIFICANCE: There is evidence that pain is both under recognized and undertreated in long term care settings. This study hoped to make a significant contribution to the evidence base for a common and problematic situation among veterans with advanced dementia. Advances in pain and symptom control are central to the improvement of palliative care intervention for dementia patients. Low-dose opiates are the logical next category of analgesics to consider, but have been rarely studied for this purpose in this population.
