Cases: Talking About Prognosis
by Robert Arnold, MD
Case:
Doctors find it hard to talk about prognosis for a variety
of reasons. Sometimes we do not like to talk about it because
we are afraid that if we talk about it, it will happen –a self-fulfilling
prophecy. I think this is often a reason that some
doctors do not like to make patients DNR - they worry that if
we make the patient DNR that we will not try as hard to correct
problems and thus they be more likely to have a cardiac arrest
(the data is controversial and this may be true). Other times, we
do not like to talk about it because it means predicting the
future, and when you predict the future you are often wrong
(what I call “the weatherman phenomenon”). Patients or
families may get mad when our predictions are incorrect which
may lead to difficult conversations in which we feel bad.
Doctors, not wanting to be wrong or feel inadequate, find it
easier to be vague (“He is very sick and may not do well” is
similar to the weatherman saying, “It is going to get brighter as
the day goes along before darkness sets in”).
Discussion:
The problem is that prognostic information, like
the weatherman's predictions, is vital to people's lives. It is
hard to make decisions about medical interventions, about
when families should come to visit their sick loved one, about
when to have serious conversations without some idea of what
the future might bring. For that reason, patients and families
are often frustrated when doctors refuse to make any
predictions about what might happen in the future. Families
understand that the future is unpredictable, and the doctors are
not all knowing and cannot know the future. Yet, they still want
to have some ideas about what we are thinking because like
weathermen, while we are not always right or wrong, we do
have some expertise in prognostication.
For that reason, I have assembled four general hints to improve
your ability to help the family think about prognostic
information. (These recommendations assume that the
patient/family wants to know prognostic data – about 75% do
according to studies.) The purpose of these rules of thumb is to
help the family begin to think about what their loved one would
say about these possible futures.
Now for the four things that you might want to do:
1) Place your information in context. It is ok to admit our
limitations in prognostication (“I do not have a crystal
ball”). Doing this places your prognostication in
context and is honest. However, it needs to be followed
by an offer to provide information based our expertise
and the available data (“I can however give you our
best prediction, based on our experience and expertise,
about what we think the future will look like”)
2) Offer outcomes as best, worst and most-likely. Toby
Campbell at the University of Wisconsin has talked
about the helpfulness of talking to patients and/or
families about the best, the worst and the most likely
outcomes. What I like about this formulation is that I
do not have to be right. I can be hopeful about what
may happen if everything goes well and yet it also
allows me to be realistic about the most likely
outcomes. It also allows space to be pessimistic about
what the alternatives are.
This formulation is helpful to families because it gives
them a range of outcomes to get their head around.
They can think about what it would mean if the “best”
outcome is one which the patient would find
undesirable. If the most likely outcome is the patient is
going to be in a nursing home, they have an incentive
to start talking to the social worker about disposition.
Finally, talking about “worst” outcomes is a chance to
think about what outcomes would be “worse than
death” for their loved one.
3) Include short and long term prognoses. Remember
when we prognosticate to think not only about this
hospitalization but also about the next 30 days, 90
days and year. It is often the case, particularly when
patients are in the hospital, that we prognosticate for
the duration of the stay that we are responsible for and
forget to talk about the bigger picture. For patients
and families the question often is not only what are we
going to think is going to happen in the short term, but
also to give a sense of what we think the longer term
will be like. (Please see e-prognosis.com for what I
think is the best website on this data.)
4) Include functional prediction in addition to mortality
predictions. Finally, when you talk about prognosis,
remember to talk both about mortality and about
function. Most people in America are not vitalists –
that is surviving with no cognitive, physical or social
function – is often not a good outcome. Given that
they are not vitalists, it is important to get again your
sense of what three months from now the best, worst
and most likely outcomes are so that they can begin to
think about what their loved one might think about
those possible realities. Talk both about functional
status expectations and what that means for setting of
care (home independently, home with 24hr care, SNF)
Resolution of the case:
You do not have to be quantitative in
your description of what you think the future is going to be – in
fact, the data suggests that patients' and families' understanding
is just as good when we use qualitative terms as when we try to
give percentages.
It is also important to remember that when you give this
information it is often heard as disturbing news to the patient or
family because by you naming it, you make it more real even if
they were not worrying or thinking about it. Strong emotions
are likely to follow your predictions, and it will take some time
to acknowledge these and ask what questions they have about
your thoughts of the future.
Someone said that 90% of life is just showing up. This saying
might be true of prognostication – you have to show up and
give your most informed views (you do not have to be right).
Beginning to offer your best judgments about the future will go
a long way in helping patients and families understand what
they are facing and hopefully do a better job of preparing for
and making decisions about the future.
