Susan Mitchell-Care of the Patient with Advanced Dementia: What Physicians Need to Know
1. Care of the Patient with Advanced
Dementia: What Providers Need to Know
Susan L. Mitchell MD, MPH
2. Goals
• Describe clinical course of advanced
dementia
• Present most common complications
• Outline an approach to decision-making
3. Epidemiology
• Over 5 million Americans have
Alzheimer’s disease, 16 million by
2050.
• 5th leading cause of death in US for
persons > 65 years
• Grossly underestimated on death
certificates

5. Advanced Dementia
Global Deterioration Scale Stage 7
– Do not recognize family
– Loss of all verbal abilities
– Non-ambulatory
– Incontinent
* Reisberg B, J Psychiatry 1982
6. Background
• Palliative care sub-optimal across
care settings:
– Under-recognition as a terminal
condition
– Prognostication
– Lack of high quality research
– Under-utilization of hospice
8. Prognosis

Challenging
Guides decision making and hospice
Very limited empiric work
ADEPT study
• ADEPT:
• Hospice:
AUROC = 0.68
AUROC = 0.55
• Receipt of palliative care should be
based on goals of care
* Mitchell SL, JAMA 2010
9. Clinical Course
• CASCADE study
• Prospective study 323 NH resident
with advanced dementia
• 22 NHs in Boston

14. Decision-Making
• Advance care planning is critical
• Opportunity to discuss early
– Prepare family for what to expect in
advanced stages
– Elicit wishes
– Set the stage for future discussions
16. Steps to Operationalize
Ethical Decision-Making
1.

3.
4.
Clarify clinical situation
Determine primary goal of care
Present treatment options
Weigh options against perceived
values
17. Step 1: Clarify Clinical Situation
• Eating problems
– Very common in end-stage
– Last activity of daily living to be lost
18. Step 2: Goals of Care
• Life prolongation
• Maintain function
• Comfort
Gillick MR, JAMDA 2001
19. Step 3: Present Options
• Supportive care vs. long-term tubefeeding (PEG or J-tube)
20. Ranking the Evidence
1st
2nd
3rd
• Randomized controlled trial
• None!
• Cohort studies
• Few
• Selection bias
• Case series (many)
• Prognostic information
• No control group
21. Options: Hand-Feeding
• Provide food and drink to the extent
that is enjoyable
• Sub-optimal nutrition in favor of
comfort
• Palliative care
– Treatment not stopped
22. Tube-feeding
• Over 30% of nursing home residents with
advanced dementia are tube-fed*
• 68% of feeding-tube insertions occur
during acute hospitalization**
• Wide regional variation
*Mitchell SL et al, JAMA;2004
**Kuo S et al, JAMDA;2009

25. Tube-Feeding: Risks
• Relatively safe procedure
• Special considerations
– Agitation
– Hospital transfer for complications
– Pressure ulcers: increased risk and
poorer healing

– Comfort
– Prolong life

28. Step 4: Weigh Options
• Expert opinion and empiric
data
– tube-feeding has no
demonstrable benefits in
advanced dementia
–tube-feeding should not be
offered

30. Step 1: Clarify Clinical Situation
• Very common in end-stage
dementia: ~ 50% last 90 days
• High mortality
• Discomfort:
symptoms* and treatment
*van der Steen et al, JAGS 2002
31. Step 2: Goals of Care
• Life prolongation
• Maintain function
• Comfort

36. Antimicrobial Resistance
• Nursing home prevalence
study (N=84)
– 64% advanced
dementia colonized
– 3 times higher than
other residents
• Nursing home residents
bring resistant bacteria
into hospitals
• Public health issue

– Prolong life

40. Hospitalization
• Most (> 75%) hospital transfers of NH
advanced dementia are avoidable…
Managed same efficacy in nursing home
OR
Not consistent with goal of care/preferences
41. Decision to Hospitalize
• What is the goal of care?
– Survival
Comfort
– 95% of proxies state comfort
• Does hospitalization meet that goal?
42. Summary
• Dementia is terminal illness
• Feeding problems and infections are
most common complications and
decisions
• Aggressive interventions are less
likely when families have a better
understanding of prognosis and
expected complications
43. Summary
• Ethical decision-making
informed , guided by the goals of care
• Tube-feeding has no demonstrable
benefits and should not be offered
• Antimicrobial treatment of pneumonia may
prolong life but also cause more
discomfort
• Most hospitalizations avoidable
44. Take home points
•
•
•
•
Opportunity for advance care planning
Focus on goals of care
Do not feel compelled to offer everything
Be knowledgeable about the best
evidence
• Use decision support tools/geriatric
consults/team
