For the third time in a 50
years, it’s hip to talk about dying (except, perhaps, if you are in the middle
of dying yourself). Interest seems to come in waves. First there was Elisabeth
Kubler-Ross, whose book On Death and
Dying, published in 1969, opened the curtains on life’s final act. Then
came Sherwin Nuland in 1994, with How We
Die: Reflections on Life’s Final Chapter. And now we have Atul Gawande with
Being Mortal: What Matters in the End,
along with several other important books, ranging from the Institute of
Medicine report, Dying in America and,
most recently, Angelo Volandes’ The
Conversation, with its overstated subtitle, A Revolutionary Plan for End-of-Life Care. It’s good that we are
talking about care near the end of life, and maybe this time the interest won’t
sputter out before we actually do something to assure that all patients die
with a minimum of pain and distress, in their homes if that’s where they want
to be, and without unwanted medical technology. But what of the months and
sometimes years before death, when so many people are neither robust nor dying,
but somewhere in between?
Patients and doctors alike
seem to want a black and white world, where you either focus exclusively on
prolonging life or you focus exclusively on being comfortable. It’s either the
ICU or hospice. Even Susan Jacoby, in her trenchant book Never Say Die, advocates that doctors “do everything possible only
if there is a realistic hope that I can emerge as a functioning, mostly
competent human being. Then stop and let me die.” She moves the bar demarcating
intensive medicine and comfort care—she thinks comfort care should begin before
dying starts rather than after it has begun—but her world is still black and
white. What I am interested in, by contrast, and why I write about people who
are frail and people in the early and middle stages of dementia, is the gray
zone.
In the gray zone, people are
not dying in any conventional sense. They are still living and may continue to
live for some time—in the case of people with Alzheimer’s disease, perhaps even
5 years—but they have begun the final phase of their lives. They are beginning
their final descent, as airline pilots so helpfully tell you a good half hour
before you reach your destination, but won’t actually land for some time, and
even then it will be a while before you arrive at the gate and can take off
your seatbelt.
Who is in the gray zone?
Principally people with either physical frailty or cognitive frailty
(dementia). People who have a serious, ultimately fatal illness such as
congestive heart failure or kidney failure or a progressive neurologic disease
such as Parkinson’s or amyotrophic lateral sclerosis (Lou Gehrig’s disease).
People who have a bad disease that will inevitably get worse and who have
embarked on the spiral of relentless decline that will culminate in their
death.
What approach to medical care
makes sense for people in the gray zone? Not everybody wants the same thing,
but it is my belief based on clinical experience, scientific evidence, and
common sense that most people who are physically or cognitively frail favor
what I call intermediate care. This is care that is focused on maintaining
whatever functions the person still has—activities such as walking, talking,
seeing, hearing, and thinking. Preserving functioning is the primary goal of
care. It may not be the only goal of care: people in the gray zone will often
wish to live longer, but only if the treatments intended to achieve this end do
not further impair their functioning. People in the gray zone usually want to
be comfortable (doesn’t everyone?), but they are willing to undergo some
discomfort in exchange for the strong possibility of holding on to the
functions they have.
What does intermediate care
look like? We tend to talk more about what it excludes than what it includes.
It excludes attempted CPR—because people who are frail almost never survive
attempted CPR and if they do, it is likely to be in a state of far poorer
functioning than before the cardiac arrest. It excludes treatments such as
risky chemotherapy and treatment in the ICU for the same reason: these medical
therapies are seldom effective in prolonging life in patients who are frail and
if they succeed, the price is usually a decline in function. What intermediate
care includes is treatments that are intended to maintain
function, things such as cataract surgery or hip fracture repair. It includes
life-prolonging treatments such as antibiotics for pneumonia or transfusions
for gastrointestinal bleeding if they can be accomplished with only a small
risk of deterioration in the person’s ability to function. That means it may
well include hospital treatment, up to a point. The distinguishing features of
intermediate care are both the benefits it is likely to confer (better
functioning, possibly longer life) and the burdens it is likely to avoid
(decline in precisely those areas that the patient values most, whether
mobility or cognition or some other domain of daily functioning). Intermediate care
can be high tech or low tech: the issue is not the complexity or the cost of
the treatment, but its effects.
We need to let patients know
they have entered the gray zone—if they mistakenly believe they will get better or they fail to realize they are dying, they will be unable to make wise choices
about the kind of medical care that is right for them. We need to
tell patients that there is such a thing as intermediate care and help them
understand what it means in practice.
