00:01
Now, there's also an
important thing to recognize that
other influences on patients ability
to make decisions for themselves.
00:10
So it may be
developmental stage.
00:12
So we've generally
been talking about adults
where we're presuming
that they have capacity.
00:16
While a patient that has
developmental intellectual disability,
they might have only
achieved a certain level of
intellectual understanding
or cognitive function.
00:25
So are they going to
actually be able to manipulate
the information and give
reasons for the decision.
00:31
And again, you have to
base it on the decision at hand,
it's not a global assessment,
it's for the particular
medical decision you're
asking them to make and
then see if they can do that.
00:43
Other chronic
influences on capacity
could be coming from
a particular culture,
you know, so are they used to
making decisions on their own
or is their cultural background
where they defer to a family member
to make decisions for them,
so they're not used to being
the one making decisions,
again, goes to capability.
01:04
Chronic Illness in and of itself,
could also affect capacity,
can go both ways,
it could mean that they're more
experienced of, you know,
making medical decisions.
01:13
But it also could mean well,
maybe their chronic illnesses
is further, you know,
debilitating them.
01:19
And they don't have
the cognitive wherewithal
to process information as well.
01:26
Any prior experience,
so either individually that,
you know, again, maybe they've
made medical decisions in the past,
maybe you're asking them
to make a medical decision
that they've already
made in the past,
like another surgical procedure
that they've been through before,
or maybe they've
had family members
that have gone
through similar things.
01:41
The patient that has
prior experience may have
a better capacity
to make decisions.
01:46
They have a better
understanding, perhaps,
they can reason through it,
they've done it before,
either for themselves or,
or with a family member,
that prior experience
might aid in their capacity.
01:57
Things that might affect
them negatively in terms
of an influence on capacity,
things like fear.
02:03
Well, maybe they're so
overwhelmed by their disease process,
they're just so fearful of
what might happen with that,
that they can't actually
do the reasoning ability
and process the information
to come to a decision.
02:18
There may be patients that
have mental health issues,
so patients that are
in major depression,
you know,
their judgment may be impaired,
maybe they have suicidal ideation,
maybe they have, you know,
decreased ability to
reason through things
and you know,
a judgment of how to make the decision.
02:35
So you might need to address
their mental health issues first,
and then determine if
they have the capacity
to make other medical decisions.
02:45
And then there may also be patients
that have cognitive decline over time.
02:49
So patients with
developing dementia,
maybe in the early
phases of dementia,
they have the ability to
make their own decisions.
02:57
But as the dementia progresses,
they may lose that ability
that lose that capacity.
03:02
So again, it has to be made
on the individual decision
you're asking them to
make or whether they
still retain the capacity
to make that decision.
03:12
So those are some more global or
chronic issues that might be considered,
they're also temporary
influences on capacity.
03:19
The first and foremost
that you're sure to encounter
when you're in the
hospital is delirium.
03:24
So a patient comes in with
a medical condition, maybe,
you know, they're so sick,
they have hypoxia,
or, you know, just so ill that
they've developed a delirium,
and you know, they're not able
to process information coherently.
03:40
Maybe a patient is
coming in intoxicated,
either under the influence of
alcohol or other substances.
03:46
And that is going to
affect their brain function,
and ability to, again,
understand and process information.
03:53
Maybe it's something
that we've done to them,
we've prescribed sedatives
or opioid analgesics
to try to help them with,
you know, some symptoms,
but those have side effects on
affecting their cognitive function.
04:06
So again, you may need to assess
whether they still have capacity,
even if they receive
medication or in some instances,
you delay giving
them the medication,
have them make the decision and
then can manage their symptoms.
04:20
There may be other
neurologic consequences,
people have head injuries
or strokes or meningitis,
you know, anything that can affect
brain function can affect capacity.
04:32
Patient patients that
are extremely fatigued.
04:34
As I mentioned, if they have hypoxia,
low oxygen to the brain,
the brain is not
going to work well.
04:39
They have low blood pressure,
they're in shock.
04:42
All those things can
be temporary influences,
once you correct those
particular problems,
maybe they regained capacity,
but certainly in the in the moment,
they might affect their
ability to make decisions.
04:54
So what do you do as a
clinician to figure out when you
might need to do a more
formal assessment of capacity?
So we're still going
to rely on those
4 criteria in
determining capacity.
05:06
But maybe they are
clues that this patient
needs a greater in
depth assessment.
05:12
So patients, it's been
demonstrated that have a mini-mental
state exam score of less
than or equal to 18 out of 30
really made have the cognitive function,
cognitive ability,
to either remember the
information or be able to process it.
05:27
So, if you have a patient
that has dementia,
where you get a mini mental
state exam score that's less than 18,
you might start by questioning
whether they have capacity.
05:41
Any patient that has waxing or
waning alertness or cognition,
they're falling asleep on us,
you're talking to them,
again, the signs of delirium, you're going
to want to do a more formal assessment.
05:53
Maybe it's a patient that makes
inconsistent decisions over time.
05:57
As I said, you want some consistency
in decisions that are being made.
06:00
If they are changing
their mind frequently,
or going back and forth,
maybe you need to, you know,
actually go through the
four steps in the assessment
to determine whether
they have the capacity.
06:14
Maybe they're making decisions,
as I said before,
that are incongruent with
their values or the goals
that they've espoused to you
of what's important to them.
06:22
If this decision
seems out of line
with what they've
told you is important.
06:26
Maybe you need to,
you know, explore further,
go more in depth and
ask more questions.
06:33
It could be the case that a
family member raises concerns
like they've seen, you know,
an adult child sees that their parent
is slowing down or
having cognitive decline,
they may raise concerns
about the patient's
ability to make
their own decisions.
06:48
We also see in
the medical context,
that there are patients,
you know,
if they've lost
capacity in the past,
maybe they've had delirium
with a previous hospitalization.
06:57
It's more likely
that they could lose
decision-making
capacity in the future.
07:01
So that's a red flag that
may require you to, you know,
do more in depth formal
assessment of their capacity.
07:09
And then you also have to
be thinking of patients that just
are not engaged in the
decision-making process.
07:15
They, you know, seem totally
unreceptive to hearing the information.
07:21
They, you know,
just say whatever you think and,
you know,
don't want to be bothered,
really want to make sure that they
are understanding the information
and coming to a decision
that's working for them.
07:32
Again, we're trying to think
about respecting autonomy.
07:35
Part of being autonomous is
making your own decisions.
07:38
So if they're limited
engagement could be a sign
that maybe something's going
on with their cognitive function.
07:46
As I said, this is a place where,
you know,
especially for patients
that have dementia,
you might need to think about,
have they regained it
because they lost it in the past?
Maybe they had delirium
on top of their dementia,
is the dementia progressing
to the point where
they're not going to be
able to make the decisions?
All of these things may need to
be factored in assessing capacity.
08:10
So it's ultimately going
to be up to the clinician
to make that determination
and then figure out what
needs to be done for
that patient in the future.
