George resides
in Seattle Washington. He suffers from
asthma and high blood pressure, but these conditions are usually controlled with
medication prescribed by his primary care physician. George goes on a business trip across the
country to Boston, Massachusetts. He
develops a pain in his chest and shows up in the emergency room at one of
Boston’s major medical centers in the middle of the night. He has never before been hospitalized and
does not have a personal health record, his health history or a list of his
medications with him. He does not even
remember the phone number for his PCP.
The ER physicians immediately do a cardiogram and see no indication of a
heart attack. They are puzzled and have
no idea how to treat George without access to his medical information,
medications, allergies, etc.
With extensive
specialization in medicine, and continual changes in healthcare insurance
coverage, most Americans receive their medical care from a number of different
providers. In our current healthcare system, these consumers are encouraged to
seek the advice of specialists and obtain second opinions. The different
providers, all keep their own health record. Although those records may be
digital, they typically cannot talk to one another. As a result an individual’s
health information becomes stored in many silos. The solution is to establish
networks of health information exchanges to enable mobilization
of healthcare information
electronically across organizations, within a region or community, and ultimately
across the country. HIEs aggregate a patient’s record in a
single data file that can be viewed by many primary care physicians,
specialists, therapists and staff at diverse doctor’s offices, hospitals,
pharmacies and labs. The advantage to
the patient is that there is continuity of care. The number of redundant tests
is reduced, along with opportunities for medical error and misinterpretation of
data.
Most Health Information Exchanges began as
Regional Heath Information Organizations (RHIOs) that received their initial
funding from grants to states. When the funds ran out, many of the RHIOs failed.
Now, most RHIOS are being consolidated into state-wide networks. The ultimate
goal is to create a national health information network NwHIN. The technology is available, but funding issues and confidentiality of patient information hamper
attempts to get this done. The NwHIN
represents a giant step forward in insuring that patient data is available at
the point of care. It also makes it
possible to aggregate data to improve population health.
