July 3, 2014 | Once
every month, a few dozen teenagers in the Boston area all receive the same
Facebook notification. The message is fed to Facebook by a local healthcare
provider, Massachusetts General Hospital (MGH), but it’s not an ad or a public
service announcement. It’s a link to a five-item test that asks questions like:
“During the past four weeks, how often did your asthma symptoms wake you up at
night?”
Teenage asthma is a persistent problem for MGH, with sufferers
repeatedly ending up in the emergency room for life-threatening events
associated with this manageable condition. These events are preventable, but
not without the involvement of the patients. Despite the serious risks of
poorly controlled asthma, teenagers in the MGH pediatric asthma clinic keep
their follow-up appointments less than a fifth of the time.
“On average, they land back in the ER about four times a
year, because of exacerbated asthma,” says Kamal Jethwani, the principal
investigator for the study MGH is conducting through Facebook. “Ninety percent
of the time the cause is that they —haven’t been able to take their medication
correctly, or they forgot to refill it… Adherence to appointments became such a
big issue that we had to figure out a way to make this easier for teenagers,
and go where they are.”
For Jethwani and his colleagues, going where the patients
are has become a guiding principle. Jethwani is the Corporate Manager for
Research and Innovation at the Partners HealthCare Center for Connected Health,
which experiments with technology-driven programs for tackling stubborn health
problems on behalf of the Partners HealthCare network in Massachusetts.
The philosophy at the Center for Connected Health is that if
a program can engage patients in their own care, positive clinical outcomes
will inevitably follow. Research at the Center does look at the standard
metrics hospitals worry about — in the case of the Facebook study, it’s
tracking hospital admissions — but it also wants to know whether patients enjoy
using the programs, and their rate of participation. “We always measure
engagement, and if we have good engagement, we consider that successful,” says
Jethwani. “It improves clinical outcomes, it improves conversations and
communication with physicians, and engagement also improves… your own ability
to take care of yourself over time. We’ve shown that time and again.”
That theory has been borne out in the group of teenagers
with asthma. One year into the program, four-fifths of these patients were
still taking their monthly asthma control tests online, allowing their doctors
to see immediately if their scores were falling below a dangerous threshold.
That’s led to a thirty percent reduction in hospital readmissions among the
Facebook group.
“It’s something really simple, just making them answer a
survey every month,” says Jethwani. “But doing it on Facebook, because they’re
already there, they’re already engaging with it every day and they see it as
part of their daily newsfeed, made it so much easier to get follow-up from
these kids.”
Marketing Health
This April, the Director of the Center for Connected Health,
Joseph Kvedar, appeared
at the Medical Informatics World Conference to explain the Center’s vision
for boosting patients’ personal involvement in their healthcare. With new
technologies like mobile phones and social networking, he told attendees, “we
can make health addictive.”
Kvedar wants healthcare providers to learn a few tricks from
the advertising industry, an idea that can be a hard sell. “Healthcare people
think of that as soft science and manipulative,” he told Clinical Informatics News, but in many regards, the ad industry
respects how people live their lives in a way that the health system rarely
has. “We think there’s a lot of good evidence that the way we approach illness
and prevention is quite broken,” he continues. “We’re constantly telling you
the bad things you’re trying to avoid, reminding you that you’re overweight, or
your blood pressure’s high, and for God’s sake get that under control. And then
if you don’t, we call you non-compliant.”
In contrast, ad agencies try to seamlessly work their
messages into people’s daily routines; and if the message doesn’t take, the
responsibility lies with the messenger, not the recipient. That’s a much more
constructive attitude to take toward the recurring problems in American
healthcare, almost all of which can only be addressed with sustained changes in
behavior. “There are six or seven use cases that keep coming back,” says
Jethwani, including diabetes, heart failure, asthma, cancer care, and smoking.
None of them can be effectively tackled during short, infrequent visits to the
clinic.
“If you think about things like chronic illness, coming in
for an office visit twice a year to get your blood pressure checked doesn’t
make sense at all,” adds Khinlei Myint-U, the Center’s Corporate Manager for
Product Development and Communications. Before coming to Partners, Myint-U
worked in online retail and online banking, a background that helps her put
programs in the context of patients’ needs.
“The consumers for banking and for other media are the same
people in healthcare,” she says. “Unfortunately, sometimes I think in
healthcare we’ve looked at patients differently, but really they’re the same
people. They want to do things that they’ll find of value, they want to do
things that are going to be easy to use… It’s about creating products and
programs that feel relevant and personal to a person.”
Moving Information
The Center didn’t always have the technology to live up to
its ambitions. When Kvedar founded the Center in the mid-1990’s, it was called
Partners Telemedicine, and its methods of bringing healthcare into patients’
homes could be byzantine and unwieldy.
“It was a different world,” says Kvedar. “We didn’t have
Netscape Navigator yet, so no form of web browser was around or at least
popular. I think people hadn’t envisioned the Internet as a place to actually
do transactions and work yet, so we thought about moving information over
private networks like ISDM lines.”
The first programs focused on heart disease, a good model
for conditions that need to be addressed at home and on a daily basis. “We had
a Windows CE clamshell device, and we hooked some sensors up to it like a
weight scale and a blood pressure cuff, and created a little home monitoring
ensemble,” Kvedar remembers. “We were able to show that patients would interact
with it, could upload their vital signs, and we could collect their vital
signs.” It was an interesting proof of concept, but far from a scalable program
for delivering system-wide improvements in cardiac health.
Ultimately, the big changes to the Center’s capabilities
were driven by even bigger changes in the country at large. The skyrocketing
market for cell phones, smart devices, and web conferencing has meant that
connected health programs no longer need to jury-rig hardware to get a new
platform off the ground. “Now, the technology exists and people already own it,”
says Myint-U. “And that’s huge, because we’re not talking about deploying
technology.” In a newer heart failure monitoring program, she recalls sending care
workers to elderly patients’ homes to distribute tablets. “What we found when
we went out there was, these grandmas were showing us their iPads, and saying
why can’t I use this instead?”
Texting was the first mobile technology to take off at the
Center, and it’s now become a staple of behavior-changing programs, for
everything from helping patients quit smoking to reminding them to use
sunscreen. Kvedar calls it the lingua franca of eHealth, a medium virtually
everyone today can engage with. Often, a program doesn’t need any more complex
interaction than text messaging to make a difference.
A good ongoing example is a text-based campaign to send
information and support to pregnant teens, which began at Lynn Community Health
Center in a small city south of Salem. “They said, our teens don’t want to read
pamphlets, they don’t answer their phones, they don’t often come in for their
prenatal visits, and we want to be able to reach them,” says Myint-U. “We
created a very simple campaign that was personalized to each patient, based on
their due date and delivery date and who they were getting care from, and there
was a series of messages that would go out to them proactively.”
Messages, which go out one to three times a week, let the
participants know what to expect at each stage of their pregnancy, remind them
to stay on top of important preparations like practice runs to the hospital,
and offer them chances to connect to their obstetrics teams. Different clinics can
also add twists to address local priorities — say, post-partum depression, or
breastfeeding.
“The great thing about texting is that you’re forced to
create these bite-sized pieces of information,” says Myint-U, which is an
important motivator for physicians who are often tempted to over-explain or use
inaccessible language. A message on a cell phone that can be read and
understood in seconds can get the essentials across where a detailed pamphlet in
a doctor’s office will almost always go unread.
The Personal Touch
The other advantage of a text campaign is that it can be
shaped to fit each individual patient’s circumstances. For the pregnancy
program, the Center can send messages based on the location of a patient’s care
center, and how they’ll need to plan a route to get there for delivery. It can
also respond to users’ interest levels — a patient who rarely reaches out the
clinic may start ignoring texts if they come too frequently, whereas on who
engages frequently might like to hear more about the support services
available.
In recent studies, the Center has been learning to take this
flexibility to a new level. “The advertising industry has done a lot of work
being able to segment people, and understand how to target products to certain
groups,” says Jethwani. “We’re trying to really get into that psyche, and think
of patients as consumers, and appeal to them in the way the advertising
industry has been able to do.”
In a fitness program for patients with diabetes, the Center
is experimenting with ways that the detailed patient information tracked
through Partners HealthCare’s electronic medical records can enhance mobile
messaging. This program, called Diabetes Connect, starts with a questionnaire
for patients, which tries to gauge their baseline level of engagement in managing
their diabetes through physical activity. At the lowest level, a patient is
considered in “pre-contemplation,” not even aware that being active could help
with their condition. At the highest level, a patient is in “maintenance,”
making changes to their lifestyle and sustaining them over time.
It may seem obvious that patients at opposite ends of this
scale will need to be engaged in different ways, but in practice these
questions are too rarely asked. Through the Diabetes Connect pilot, which
monitors patients’ activity levels over time using freely-distributed Fitbits,
the Center for Connected Health can speak to each patient’s current needs. For
a pre-contemplation patient, says Kvedar, “you’re going to get a lot of
educational messages about ways that you can add to your step count without
rearranging your life. It might mean parking your car farther away from the
restaurant, or taking the stairs in a building.” Meanwhile, for a patient in
maintenance, “your messaging will be more congratulatory – keep up the good
work – but also ways you can extend your enthusiasm: challenge yourself, set a
new goal.”
Diabetes Connect also layers in medical data from Partners’
records, which is Jethwani’s area of expertise. “Our EMR data allows us to be a
little more clinically accurate, in order to understand or predict how quickly these
patients will move,” he says. “For example, recently diagnosed diabetics
usually take much longer to make changes than people who have internalized
their diagnosis over a number of years. Insulin makes it very real for
patients, because they know they have to take an injection every day… We see a
very big difference.”
Overall, there are twenty-five dynamic categories for
patients in Diabetes Connect, each with its unique system of messages. The live
Fitbit data on activity levels lets the Center shift patients up the scale in
real time, tweaking their messaging to meet them at each new level. The program
even responds to the weather, sending out different messages on rainy days to
help participants get in their daily activity indoors.
While the study is still in its pilot phase, and data on
clinical outcomes are not yet available, Diabetes Connect has been hugely
successful on the metric that matters most to the Center: 80% of patients have
stayed engaged with the program through its duration.
Understanding
Incentives
In many ways, the Center’s work is a study of the incentives
that move people to change their behavior, which are not always as simple as
the vague knowledge that we need to live healthier lives. “The transition from
the hospital to the home is an area we’re really interested in,” says Myint-U. “It’s
a kind of trigger point, where people are really interested in their health, and
open to something that’s new,” and that gives the Center a higher success rate
with appropriate interventions. People with strong social networks, and lots of
social interactions, are also more likely to stick with new behaviors, which
suggests new avenues for the Center to pursue in social media or online support
forums.
There are also strange disincentives at work in healthcare.
The clinicians themselves can be an obstacle to the uptake of new programs, if
tools aren’t designed with the doctors’ ease of use in mind as well as the
patients’. “Doctors don’t want to use a separate website,” says Myint-U. “They
don’t want to start any more log-ins. They just won’t use it. We did a study
early on that showed the engagement of the doctor was directly correlated with
the engagement of the patient.” That has guided the design principles behind
new platforms ever since.
The social barriers between patients and their physicians
can also stand in the way of delivering the best care. The Center has gotten
involved in cancer pain precisely because of this sometimes fraught
relationship, where patients don’t always feel able to be totally honest with
their doctors.
“Eighty percent of cancer pain is either underdiagnosed or
undiagnosed,” explains Jethwani. “Patients have these feelings about cancer
pain, that they need to feel the pain in order to make the cancer go away, or
if they tell the doctor about their pain they’ll stop the chemotherapy.” To
take away the temptation for patients to underplay their pain for their
doctors, the Center introduced a pain-tracking app that prompts regular pain
reports every few days.
Using an app not only leads to better reporting of cancer
pain; it’s also more responsive to how pain can change over time. The app can
tweak medications, ask patients questions about their side effects and
medication adherence, and even be used to order prescription refills in a
fraction of the time it takes the hospital system.
That variety of uses shows how extensible tools developed at
the Center for Connected Health can be, especially when they’re built for smart
devices. “We have all this rich information now being driven from patients into
the app that we’re making available to our clinicians,” says Jethwani. “So I
can easily see this being deployed in oncology centers, and training
physicians, or creating decision support, to improve how we manage cancer pain
overall.” That rich dataset could also be used in the future to target this
kind of program to the patients who most stand to benefit. At present,
oncologists recommend their patients for the cancer pain app, but there’s no
reason that Partners couldn’t use data from medical records to predict which
patients would see the most value from the program.
Not every program started at the Center is a success. They
nearly all begin as small pilot studies, tracking one or two hundred patients
over six months or a year, and often they’re discontinued after that point. But
the most effective tools become implemented system-wide at Partners, or get
spun out into new companies or licensing deals. And each study brings the Center
closer to understanding the incentives that move patients to take better care
of their health, and what kinds of outreach they’re most likely to interact
with.
The rapid uptake of mobile technology is turning the
platforms created at the Center into models for care that could soon be broadly
adopted. Kvedar hopes that the ease with which these campaigns can reach
patients at home, and the evidence his Center is collecting that patients are
interested and willing to participate, will help shift perceptions of how
doctors can connect to their patients.
“As healthcare providers, we manage everything the same way,”
he says. “You come see me in the office, and I take care of you. And if I don’t
see you, I don’t think of you, and you come more often when you’re sick than
when you’re not. That just doesn’t work well for chronic illness management and
prevention.” For the biggest challenges facing the American healthcare system,
care centers will have to learn to reach outside their walls.
