A Patient’s Choice in Treatment Affects PTSD Outcomes
what treatments is your doctor prescribing? Has your doctor even tested you for PTSD?
Maybe one of these?

There are also some states allowing medical marijuana for PTSD.

Switch your television to virtually any medical drama
and you’ll see the same scenario unfold again and again. After struggling to
diagnose a patient with complex symptoms, a doctor will mandate a particular
treatment—and, lo and behold, the patient recovers. In some ways, it’s no
surprise that this is how patient-doctor interactions are represented in the
media. The healthcare system, both in the United States and Europe, has
operated on a “doctor knows best” mentality for decades. Yet research suggests
that allowing patients to choose their treatment can improve how well they
respond to it. A new randomized control trial out of the University of
Washington and Case Western Reserve University has demonstrated that people
diagnosed with post-traumatic stress disorder (PTSD) show a greater reduction in
symptoms—even, in some cases, no longer qualifying for a PTSD diagnosis—when
they are able to make the decision whether to treat their condition with
medication or prolonged exposure therapy.
The power of
shared decision-making
Jennifer Blumenthal-Barby, associate director of medical
ethics at Baylor’s Center for Medical Ethics and Health Policy, says that with
the healthcare industry moving towards more “patient-centered” and “value-based”
healthcare over the past few years, healthcare systems want to find ways to involve
patients in their own care and reduce healthcare costs. Shared medical
decision-making, a process in which clinicians and patients work together to
make medical decisions, including deciding on treatment plans, using clinical
evidence and the patient’s preferences, is one way to do just that.
“In situations where patients are part of this process,
research indicates that it can improve health outcomes for patients,” she says.
“There are several reasons for this. First, it can improve a patient’s
perceptions of the healthcare experience and their providers, helping the
patient understand they can play an active role in their own care. Second, when
they do feel engaged in this way, patients are much more likely to be compliant
and adhere to a particular treatment regimen.”
Research studies have shown that shared decision-making
has led to better outcomes for people with conditions including diabetes,
cardiovascular disease, and various cancers. But some have questioned whether
it would work as well in behavioral health conditions. Nicola Morant, a
researcher at England’s Cambridge Clinical Research Centre for Affective
Disorders, says that it can work just as well in the psychological and
psychiatric realms—though the empirical research on its efficacy lags behind
that done concerning physical health conditions.
“When it comes to mental health, we are partly behind
because of notions of what it is to be mentally ill,” she says. “Particularly
with conditions that include psychosis, there is the idea that the person
doesn’t have the capacity to make rational decisions about care. But we’re
gradually challenging those ideas and showing that even people in acute mental
health crisis are able to make decisions when supported.”
Making a choice
for PTSD treatment
Lori Zoellner, Ph.D., a psychologist at the University
of Washington, says that there are now several viable, evidence-based options
to treat PTSD, a psychiatric disorder that can occur in people who have
experienced a traumatic event. Yet it’s difficult for psychiatrists and
psychologists to know which treatment to offer.
“Before, we were asking, ‘Does this treatment work?’ Now
we know that quite a few do,” she says. “So then the question becomes, ‘From
whom does a particular treatment work and when?’ There’s some evidence that
patient preference plays a role. And if we’re going to get better at
personalizing treatment options, we need to understand what the role of preference
actually is.”
Zoellner and colleagues recruited 200 people who had
been diagnosed with chronic PTSD. Each was asked state a preference for
treatment: a medication-based approach, the drug Sertaline (better known as
Zoloft), or a behavioral therapy known as prolonged exposure therapy, where
patients are asked to gradually approach traumatic memories in order to better
process them. The participants were then randomly assigned to a group in which
they received their preferred treatment or a group in which they were randomly
assigned to one or the other. The researchers found that the 74 percent of the
patients who chose and then received prolonged exposure therapy had reduced
their symptoms to the point of losing their PTSD diagnosis two years later. Only
37 percent of those who would have preferred therapy but received medication
reached the same status. What’s more, nearly three quarters of patients who
were able to choose their preference completed the full treatment program,
while more than half of those who did not receive their preference did not
complete their treatment. The results
were published October 19, 2018 in the American Journal of Psychiatry.
Zoeller says she and her colleagues are trying to
understand why the effects were so profound—and plan to follow this study with
more research to “unpack” why preference played such a big role in treatment
outcomes.
“Some of the ‘whys’ are evident in this data,” she says.
“One of the ‘whys’ is that preference reduces drop-out. People are more likely
to stick around and finish the treatment if it’s consistent with their
preferences. Second, it clearly has an impact on adherence. People are more
likely to take their medication or do the therapy homework if it’s their
preference. They are showing up, they are doing the work, and that confers the
benefits.”
Moving towards
shared decision-making models of care
Most medical conditions, including psychiatric disorders
like PTSD, anxiety, and depression, can be successfully treated with a variety
of different approaches. While many research programs are looking towards
genetic profiles and other biomarkers to help guide treatment decisions,
Zoellner hopes that both providers and patients will understand that patient
preference is valuable, too.
“We need to be able to better match psychiatric
treatments to the individual in the future,” she says. “The best match is not
only going to include biological characteristics and psychological symptoms,
but also the patient’s wants, desires, and choices.”
Blumenthal-Barby says that many doctors may not be aware
of the importance of shared decision-making for health outcomes—nor might they
understand the best way to include the patient into these important treatment
decisions. But she expects that we will see more shared decision-making, both
in medical and behavioral health spheres, in the future, moving from the
“doctor knows best” model to “the patient and doctor can work together to come
up with the best option.”
“When patients feel more heard, when they understand the
pros and cons of a given treatment, and when they feel like they are playing an
active role in their own care, it really makes a difference,” she says.
