End-of-Life Dementia Care: A Palliative Perspective
Psychiatrists need to be aware of aspects of psychiatric and pain management that are unique to end-of-life care for patients with advanced dementia. The palliative care philosophy presents an opportunity to honestly acknowledge the terminal nature of advanced dementia, limit intrusive and unnecessary care, and thoughtfully address pain and suffering.
Studies suggest that nursing home patients with severe dementia have an average life expectancy of 2 years. (1) These patients often have substantial medical comorbidity, frequently with multiple illnesses, each of which has an accepted management that may involve several medications and interventions. Treatment guidelines for individual conditions don't necessarily take into account multiple interacting illnesses in advanced dementia. Applying recommended treatments for multiple conditions simultaneously may entail prescribing many medications and interventions. Often these techniques are designed to prevent or modify disease over long term, which a patient with advanced dementia is not likely to achieve. (2)
Such polypharmacy and intensive intervention are not likely to extend life or improve its quality. In fact, the opposite may occur. Dementia patients react poorly to polypharmacy and may require restraint or sedation to accommodate invasive interventions. Feeding tubes are particularly challenging. Studies have revealed that feeding tubes do not extend life in advanced dementia patients. (3)
Goals for palliative care. The palliative care approach emphasizes relieving suffering in the near term. Applying this philosophy to advanced dementia depends on acknowledging that the patient will not recover from this condition, has a limited life expectancy, and is not likely to benefit from--and in fact may be harmed by--an aggressive approach to comorbid conditions. Instead, these conditions are best managed by controlling pain and suffering in the near term. …
