March 28, 2014 | Browsing through the Phoenix Rising forums – the largest
online meeting place for people living with the mysterious neurological disease
ME/CFS – can feel, to the uninitiated, a little like rifling through the
collected letters of a hundred medieval alchemists, each suspecting he’s just
two or three ingredients away from the exact formulation of an elixir of life.
Members share, scrutinize, and revise the most extraordinary drug regimens
you’re ever likely to find. Some ME/CFS patients post their entire personal
pharmacopeias on the forums, which in extreme cases can run to twenty, thirty
or more items, combining prescription and over-the-counter medications, vitamin
supplements, “alternative” medicines, and dietary injunctions.
Yet despite – or even because of – the dizzying blend of
treatments, the spirit is largely one of rational inquiry and empiricism. Members
drill into the cellular and metabolic activity of each drug they take, with an
eye for conflicts and interactions with other items in their regimens. They add
new treatments in low doses, build them up, and substitute related compounds
over a period of months, tracking how each change affects their symptoms and whether
it leads to side effects. Few aspects of their daily lives escape scrutiny –
they debate ubiquinol vs. ubiquinone, but also tea vs. caffeine pills, meal
schedules, ways to get light exercise.
Their liberal self-medication is not a deliberate thumb in
the eye to the healthcare system, but a result of living with an often
debilitating disease for which there is no standard of care. It is not clear
what causes ME/CFS, or even whether it is a single disorder or a collection of
related diseases. The most common symptoms are constant exhaustion, “brain
fog,” and pain in the limbs and joints, but many patients also suffer from
recurrent cold- or flu-like illnesses, gastrointestinal problems, and a
perception that very slight changes in diet or behavior have large and lasting
impacts on mood, energy levels and cognitive function. The most affected
individuals may have trouble walking more than a few hundred steps a day,
unloading the dishwasher, or concentrating long enough to read a book.
Even the name ME/CFS reflects a basic uncertainty about the
disease. CFS stands for “chronic fatigue syndrome,” which is usefully
descriptive but troubles many patients and patients’ advocates because it may
come across as trivializing. ME stands for “myalgic encephalomyelitis,” which
has a more authoritative air but may not be strictly accurate, implying that
the syndrome is rooted in brain inflammation. Researchers have suggested any
number of causes that might contribute to ME/CFS, including autoimmune
disorders, infectious agents, genetic predispositions, and a number of
psychological factors.
Faced with this level of uncertainty, and a desperate need
to control their symptoms, each member of the Phoenix Rising community is
essentially running an elaborate n-of-one study on the disorder, often with
great diligence in recording the outcomes.
Dr. Andy Kogelnik, and his Open Medicine Institute (OMI),
would like to take “n-of-one” out of that equation.
Outcomes on a
Patient-by-Patient Level
“We’ve built a system
of healthcare that’s great at dealing with acute disease, but it’s really bad
at dealing with chronic disease,” Kogelnik tells Clinical Informatics News. “And over half
of Americans now have a chronic disease… There’s a lot we need to do in terms
of measuring, and tracking, and understanding these diseases from a very
different perspective.”
ME/CFS is far from the only condition in the Open Medicine
Institute’s wheelhouse, but, says Kogelnik, “we view it as a really important
model for chronic disease, and a model of what we need to fix in healthcare.”
He first encountered the disorder as a fellow at Stanford; like most doctors,
he had never heard of it in medical school. “I happened to bump into some of
these patients in clinic,” he remembers. “They didn’t come out and tell me that
they had chronic fatigue. They had actually come in for very high viral numbers
on their labs, and the fatigue part only came out later in the story… It was a
very interesting introduction into a field that has been at the fringe of medicine,
but is affecting larger and larger numbers of people.”
For eight years at Stanford, Kogelnik worked as a
bioinformatician, combining patients’ clinical information with molecular data,
particularly from the genome. His projects were good at profiling patients at
discrete intervals, but he felt that by relying on data that could be gathered
in the clinic, he was missing out on a longitudinal picture, and on health
outcomes important to the patients themselves. By the time Kogelnik founded OMI
in 2009, with a mission to assemble a diverse clinical dataset for new studies
into chronic disease, he had become convinced that allowing patients to
contribute their own data to research was the only way to get a 360° view of a
chronic illness.
Today, OMI maintains a biobank, an informatics facility, and
a CLIA-certified laboratory for both molecular and physiological testing. The
centerpiece of the institute, however, is its online platform, OpenMedNet.
OpenMedNet is a little like an electronic medical record, in
that it captures and stores a patient’s history of medical problems,
interventions, and outcomes. Unlike an EMR, however, the platform’s primary
administrator is the patient, who can not only access the system at any time
and enter new personal information, but also has final control over who can
access her profile. Familiar clinical data can be included – prescriptions,
test results, vital signs taken at discrete times – and for this data, OMI works
with care providers to interface their EMRs directly into the system. But if
patients want to track their diet, or exercise, or the frequency of their
headaches over the course of a day, they can create fields for that information
as well.

In the ME/CFS community, many patients are fastidious data
trackers, using wearable technology like Fitbits to quantify their movements
and sleep cycles – two metrics that are hugely disrupted by the disease.
OpenMedNet provides a convenient place to store all this information together.
Even for more casual users, OpenMedNet offers valuable resources like
medication reminders.The platform is free to patients, and they can treat it as a
self-enclosed record-keeping environment if they want to. But most active users
grant access to their physicians, seeing OpenMedNet as a way to share
information that’s important to people living with chronic disease, but that
doctors rarely seek out on their own. A patient’s profile is also a portal for
communication, and doctors and patients can leave notes for one another. At the
same time, patients can connect with other patients, to compare treatments and
lifestyle management choices – and physicians can connect with one another as
well. Says Kogelnik, who is still a practicing physician in addition to his
role as Director of OMI, “We wanted a place where doctors would be able to say,
‘I’m seeing this patient, and I’m not sure what to do with him. Has anyone else
seen a patient like this?’”
From the perspective of care providers, he adds, “you can
actually start to track outcomes on a patient-by-patient level. With EMRs, the
encounter ends when the patient leaves the hospital, and we don’t get long-term
tracking data in terms of what actually happened when you gave that antibiotic,
or that heart medicine. That’s a key piece that’s missing from the system.”
The Open Medicine
Principle
While these services are valuable in their own right,
ultimately the patient portal in OpenMedNet is a gateway for research. OMI
forms partnerships with insurers, foundations, government agencies, and
pharmaceutical companies to take advantage of the large population of data in
OpenMedNet for studies of complex chronic diseases. The model is not selling
patients’ data to collaborators, but allowing patients to opt in to research –
whether by taking advantage of prospective new therapies, or just donating
information.
“The patient ultimately is the one who gets to decide how
their data is shared, and with whom, and how they can view and access that,”
Kogelnik emphasizes. Data can be anonymized and stored in dedicated registries
for specific projects, or patients can grant total access to relevant areas of
their profiles – and they can offer different levels of access to different
collaborators.
This principle of data sharing is the defining feature of
OMI. “[The name Open Medicine Institute] really came from the open source
movement,” says Kogelnik. “Not that we’re going to open source everyone’s
medical data, but we give people the option to have whatever level of openness
they want around their data… We have a really high opt-in rate in terms of
community participation.”
With its large core of patient volunteers, OMI serves as a
base for two kinds of research projects. The institute can host clinical
trials, reaching out directly to patients in OpenMedNet to quickly assemble
large disease cohorts. The informatics facility can also retroactively mine the
data shared through OpenMedNet for biomarkers in patients’ genomes, gene
expression levels, or protein levels, which might be predictive of a disease’s
severity or progression.

In either case, a new project will involve recruiting
patients for new tests or therapies. Unlike other research organizations,
however, OMI doesn’t have to assemble a new patient cohort from scratch, and a
great deal of relevant data will already be stored in the system. “Part of what
we do on the collaborative side is create datasets that are larger and larger
interesting groupings of data from patients, and try to profile them in greater
and greater depth,” says Kogelnik. Thanks to key partnerships with VMware, EMC,
and Hewlett Packard, the OpenMedNet cloud can support enormous amounts of data,
up to the level of whole genomes.OMI focuses its research efforts on underserved chronic
diseases, especially those with complex and variable pathologies. Current
priorities, in addition to ME/CFS, include autism and Lyme disease.
“One thing that all these conditions share,” says Kogelnik,
“is a lack of good diagnostic tests, and solid criteria around how you define a
patient or case.” This makes biomarker studies all the more important, to help
clarify the range of disease presentations, and potentially subdivide patients
into meaningful groups of like cases.
These diseases also tend to share tightly-knit patient
communities. While designing meaningful studies might be very difficult,
finding willing volunteers is not. For a new autism initiative, for instance,
OMI is preparing a partnership with Talk About Curing Autism (TACA), an
organization of 40,000 families with children with autism. “They’re all very
invested in finding answers for their kids,” says Kogelnik, “and they’re
already partially online, so we can interact with a larger number of their
membership.” From this population, OMI hopes to recruit 500 families willing to
share samples for genome sequencing, immune system characterization, and
pathogen detection, as well as daily information on diet and activity.
In the ME/CFS community, OpenMedNet is already becoming a
popular destination, in part because so few organizations are investing
resources into understanding the disease. A number of research projects are
already ongoing, which Kogelnik is happy to rattle off. “We’re collaborating
with groups like Applied Proteomics, looking at 300,000 different protein features
in patients’ blood. We’re doing some whole genome sequencing with the Genome
Center up at Stanford. We’re doing a couple of gene expression studies looking
at pre- and post-treatment in responders and non-responders to certain
medications.”

The flexibility of OpenMedNet allows some offbeat sources of data to enter the conversation. Partnering with Brain Resource, OMI makes a series of online cognitive tests available to a cohort of around 5,000 ME/CFS patients, asking them to log in periodically to test basic functions like memory and reaction time. This creates a longitudinal measurement of cognitive function that can be referenced against different therapy options.There are also straightforward clinical trials, including of
the autoimmune drug Rituximab and the antiviral drug Valganciclovir, working on
the theory that ME/CFS may involve a hyperactive immune response to a
triggering infection. Because OMI investigates questions of interest to the
patients themselves, trials are also underway on treatments with anecdotal
support, but little theoretical grounding – including vitamin B12, the plant Moringa oleifera, and the antimalarial
drug artemisinin. By scaling up to randomized, placebo-controlled trials, OMI
hopes to steer patients toward therapies with sound scientific support.
Complementing Health IT
Systems
OMI is a community benefits corporation – “halfway between a
full non-profit and a regular corporation,” says Kogelnik. In this capacity,
the institute agrees to added financial transparency, and that its profits
should be driven toward a social good.
Nevertheless, it is a for-profit business, and it has to
find ways to create revenue while offering a free service to patients.
Sometimes, this is tangential to the research goals of OMI. While the institute
built its CLIA lab to draw and analyze samples for its own projects, it also
rents out its laboratory services for contract work.
Clinical studies are a major source of revenue, whether by
seeking funds for original ideas – OMI’s ME/CFS studies have attracted grants
from the Centers for Disease Control as well as private donations – or by acting
as a portal for patient enrollment, for studies created by pharmaceutical and
diagnostic companies or philanthropic organizations.
Most importantly for the institute’s continued growth,
OpenMedNet itself is a commercial product. For a few physician practices,
OpenMedNet has been adopted in place of a traditional EMR. For larger
healthcare providers, the platform can be linked to existing EMRs as an added
point of contact between doctor and patient. OMI also provides these clients
with integrated IT services – for instance, using OpenMedNet’s connection to
wearable devices and other health monitors to alert providers through text or
phone when high-risk events occur.
“That not only is part of our business model, but it is also
a source of more data,” says Kogelnik. As hospitals and insurance providers
connect their patient populations to OpenMedNet, OMI can bring thousands of
patients at a time into the system. Only a fraction of those become active
users, but it raises awareness of the platform, and helps attract healthy
individuals to serve as controls in clinical studies. “We partner with a number
of different insurance payers to provide wellness services to [their
customers],” says Kogelnkik. “We help those people to manage and keep
themselves healthy, and a certain percentage of them are attracted to helping
us with research, and provide samples or data.”

In addition to driving future research, OMI’s work as an IT
provider for healthcare systems can offer some immediate clinical benefits. In
an ongoing project, the institute is using Cepheid’s Xpert rapid tests for
microbial infections, and building medical alert systems that can keep pace
with the diagnostic technology. “Even if a rapid instrument is in a lab,” says
Kogelnik, “the data doesn’t always get back to the physician and the patient to
make a decision and put them on treatment. We take the result directly off the
instrument, and push it out through a system of secure alerts on mobile devices
to the doctor, who could then make an instant recommendation for treatment.”
The system also allows the doctor, after reviewing the diagnosis, to send a
second text alert to both pharmacy and patient. “It alerts the patient that
they have a new diagnosis and a prescription waiting, and by the way, based on
your mobile phone you’re half a mile from a pharmacy so would you like us to
send the prescription there?”
“If you cut down some of the time to treatment, you can have
very large impacts on the diseases you’re trying to treat,” he adds. “There’s a
lot of waste in the system in terms of lost time, which translates into
increased mortality or morbidity.” With programs like this rapid text alert,
OMI hopes to make its IT service more attractive as a complement to a large
EMR, which is rarely flexible enough to serve as a portal for doctor-patient
communication. This in turn generates revenue and introduces OpenMedNet to new
groups of patients, allowing OMI to gradually take on new diseases like multiple
sclerosis and certain cancers.
“We view this as a personalized medicine platform,” says
Kogelnik. “EMRs were built with research and billing in mind. Our system is
built with investigation and collaboration in mind.”
