    to Participants

6
Hospice
Hospice care is a compassionate method of caring
for terminally ill people. Hospice is a medically
directed, interdisciplinary team-managed program
of services that focuses on the patient/family as
the unit of care. Hospice care is palliative
rather than curative, with an emphasis on pain
and symptom control, so that a person may live
the last days of life fully, with dignity and
comfort, at home or in a home-like setting.
- National Hospice and Palliative Care
Organization
7
Palliative Care
The active total care of patients whose disease
is not responsive to curative treatment. Control
of pain, other symptoms, and of psychological,
social, and spiritual problems, is paramount.
The goal of palliative care is achievement of the
best quality of life for patients and their
families. - World Health
Organization, 1990
8
Identity CrisisHospice vs. Palliative Care
  • Hospice
  • A movement or a reimbursement mechanism?
  • Medical counterculture adopted by the mainstream?
  • Too exclusively focused on dying?
  • Palliative Care (Palliative Medicine)
  • A part of mainstream medicine? A specialty?
  • More academic, research oriented? At the expense
    of focus on patients and families?
  • Too afraid of being identified with care for the
    dying?

9
UK Model vs. US Model
  • UK
  • Hospice is a place, a facility with beds
  • Home care is an outreach service
  • Supported largely (primarily?) by philanthropy
  • US
  • Hospice is a philosophy of care
  • Most hospice care is delivered in the home
  • Supported through 3rd-party reimbursement

10
Dying in the United States
  • Good news Americans are living longer with more
    of our years spent in good health and quality of
    life.
  • Bad news is twofold
  • We now tend to die of chronic illness over time
    (with chronic symptoms and suffering).
  • The US healthcare system is ill prepared to
    manage a large cohort of aging people dying
    slowly with chronic illnesses.

11
Expanding the Range of Services
  • Home hospice care
  • Day hospice (Day respite) care
  • Palliative care consultation services
  • Outpatient palliative care clinics
  • Inpatient palliative care units
  • Collaborative LTC/Palliative care programs
  • Bereavement care programs

12
Goals of Palliative Care

13
Goals of Palliative Care
  • Non-abandonment
  • Among the things patients and families fear most
    is being alone
  • Assuring non-abandonment is one of the most
    healing things a palliative care program can do

14
Goals of Palliative Care
  • Symptom Control
  • Pain
  • Depression/Anxiety
  • Fatigue/Weakness
  • Nausea/Vomiting/Diarrhea/Constipation
  • Respiratory distress
  • Proactive assessment patients unlikely to
    voluntarily report symptoms accurately
  • Multiple symptoms are the rule

15
Goals of Palliative Care
  • Assistance with Specific Life Goals
  • Important upcoming events
  • Meaningful projects
  • Preparatory tasks (Getting affairs in order)
  • Saying the Five Things (Byock)
  • Please forgive me I forgive you Thank
    you I love you Goodbye

16
Goals of Palliative Care
  • Integration of the experience of lifes end
  • Attending to suffering in all domains
  • Biological and Physical
  • Psychological and Emotional
  • Social and Interpersonal
  • Spiritual and Religious
  • Intellectual and Professional
  • Reviewing ones life narrative
  • Focusing on meaning

17
Goals of Palliative Care
  • Help with bereavement, grief, and loss
  • Patient and family
  • Anticipatory and reactive

18
Goals of Palliative Care
  • Maintaining hope
  • A confident expectation that good will come to
    one in the future
  • Preserving dignity
  • Value, esteem, lovability
  • Healing vs. cure
  • It is possible to die healed
  • Wholeness vs. Eradication of disease

19
Who Are Our Patients?

20
Who are our patients?
  • Is palliative care best viewed as holistic,
    person-centered care for persons with chronic
    illness that begins at the time of diagnosis?
  • Medical turf as a political problem
  • Is palliative care essentially focused on care at
    the end of life?
  • The stench of death as a PR problem

21
Medicare Hospice Benefit
  • To be eligible, a patient must
  • Receive services from a Medicare-certified
    hospice
  • Have a prognosis of six months or less
  • If the disease runs its normal course
  • In the opinion of two physicians
  • Be willing to forego life-extending therapy
  • Sign an election form to this effect

22
NHPCO Guidelines
  • Designed to help with estimating hospice
    eligibility (i.e., a high probability of
    six-month mortality) in patients with non-cancer
    diagnoses
  • In wide clinical use (as modified by Medicare
    fiscal intermediaries)
  • Require substantial clinical judgment
  • Relatively poor predictive value

23
The Course of End-Stage Dementia
  • Interval between diagnosis and death in
    Alzheimers Disease may be 10 years
  • The end stage of the illness may last as long as
    2-3 years
  • End-stage dementia is a poor fit for the standard
    hospice benefit (6-month prognosis)

24
Determining Hospice Eligibility in Dementia
  • No cure for dementia - treatment is essentially
    palliative from the time of diagnosis
  • Published guidelines were developed for
    Alzheimers
  • Guidelines describe clinical predictors of
    six-month mortality in dementia

25
Determining Hospice Eligibility in Dementia
  • Patient must be at or beyond Stage 7 on the
    Functional Assessment Staging (FAST) Scale
  • Unable to ambulate
  • Unable to bathe, dress, or feed independently
  • Incontinent of bowel and bladder
  • Unable to communicate meaningfully
  • (Presence of medical complications)

26
Length of Stay in Hospice
  • Median length of stay for all diagnoses -36 days
    (Christakis and Escarce, NEJM, 1996)
  • Significantly longer for dementia, COPD
  • Dementia seen as a problem diagnosis by hospice
    regulators
  • Median length of stay for dementia patients in
    hospice care was well below six-month limit

27
Estimating Prognosis for Dementia in LTC
  • Mitchell, et al, JAMA, 2004
  • Looked at all patients admitted to NH in New York
    or Michigan over 6 years (Ngt10,000)
  • Only 38.5 of those with FAST gt7 died within six
    months
  • Authors proposed an alternative prognostic
    scoring system based on variables obtained from
    the MDS

28
TVAMC Chart Audit Study
  • Shuster, Rice, Tucker, Allen (Unpublished)
  • All veterans admitted to a Geriatrics and
    Extended Care bed on January 1, 2004 (N 189)
  • Looked at
  • Potentially life-limiting diagnoses
  • Evidence for meeting hospice eligibility
    guidelines
  • Six-month survival

32
The Essential Problem
  • Hospice eligibility focuses on six-month
    mortality.
  • FAST is a poor predictor of mortality.
  • End stage dementia lasts from 2-3 years
  • What fills the gap?
  • The familys perspective Where have you been?
    We needed you two years ago.
  • Critical treatment decisions have often already
    been made.

33
Biases That Want to Become Theories

34
Bias 1
  • Peace is the Word
  • An integrative, overarching concept
  • The most important outcome
  • Associated with suffering and symptom control
  • More closely associated with relationships and
    religious/existential factors

35
Bias 2
  • Effective Palliation is Characteristically
    Proactive
  • Its easier and more effective to stay ahead than
    to play catch up
  • Common problems can be anticipated
  • Proactive intervention is more effective and less
    expensive across care settings

36
Efficacy of Proactive Symptom Management
Strategies
  • Clearly demonstrated for pain
  • By the clock Dame Cecily Saunders
  • Rationale for PCA pumps
  • Multiple studies of prophylactic and preoperative
    analgesia
  • What about anxiety? Dyspnea? Nausea?

37
Bias 3
  • Reactive Intervention is Most Effective When
    Guided by Subjective Priority
  • Multiple symptoms and problems are the rule
  • Symptoms and problems have variable impact on
    suffering among individuals
  • Taking patient priority into account improves
    effectiveness of interventions

38
Prioritizing Symptom Control
  • Mostly a result of clinical observation
  • Validation studies of the Memorial Symptom
    Assessment Scale (MSAS)
  • Advanced cancer Approx. 12 symptoms/patient
  • Advanced AIDS Approx. 18 symptoms/patient
  • Cant intervene on this many symptoms at once
  • Emerging concept of symptom clusters (and
    pro-inflammatory cytokines as mediators)

39
Bias 4
  • Complications of Grief and Loss are Related to
    Trauma
  • A proportion of grief sufferers need formal
    intervention, not just companioning
  • Intervention is feasible, acceptable, and
    effective
  • Complicated bereavement is related to PTSD, other
    anxiety and mood disorders
  • The circumstances of a loved ones death
    influence adaptation to grief both positively
    and negatively
  • Religious faith (peace) buffers against the
    trauma of loss

40
Bias 5
  • End-of-Life Interventions for Dementia Patients
    are not Futile
  • Symptoms can be anticipated and assessed
  • Remediable or treatment-responsive symptoms can
    be detected and outcomes measured, demonstrating
    benefit
  • Effective treatment alleviates suffering and
    improves QOD
  • Effective treatment lessens the burden of family
    bereavement

41
Research Projects and Initiatives
  • Validation of a brief assessment strategy
  • Evaluation of a legacy intervention
  • Developing a clinical measurement for peace
  • Document trajectory of palliative care needs for
    dementia patients, to shape studies of
    interventions

42
Research Projects and Initiatives
  • Observational study of loss and coping in
    patients with known anxiety disorders (PTSD, GAD)
  • Symptom control preliminary studies
  • Rates of delirium in the last week of life
  • Emergency drug kits in home hospice care

43
Palliative Care ResearchBarriers and Benefits
to Participants

44
Barriers
  • Attitudes
  • Leave him alone, for goodness sake, hes dying.
  • Philosophy
  • Hospice as counterculture anecdotal
  • Tolerance for observation?
  • Logistics
  • Most patients are at home
  • Priorities
  • Hospice staff are really busy
  • Hospice patients have limited stamina

45
Survey of Attitudes Toward Research Participation
  • Williams C, Burgio K, ShusterJ (unpublished)
  • Survey results from 142 hospice patients served
    by 21 hospice facilities in AL, FL, LA, and MS
  • 39 response rate
  • Survey focused on attitudes about participation
    in hospice research

52
Benefits of Participation in Palliative Care
Research
  • Compared to their family caregivers, hospice

  • Feeling good about helping others (p0.02)

53
Summary
  • Palliative care is increasingly important in
    geriatrics and geriatric medicine
  • Multiple gaps in the knowledge base
    (opportunities for research)
