Introducing
HL7
FHIR
Introducing HL7 FHIR
FHIR® – Fast Healthcare Interoperability Resources (hl7.org/fhir) – is a next generation standards framework created by HL7. FHIR combines the best features of HL7's
v2
,
HL7
v3
,
HL7 v3
and
CDA
and
CDA
product
lines
while
leveraging
the
latest
web
standards
and
applying
a
tight
focus
on
implementability.
FHIR
solutions
are
built
from
a
set
of
modular
components
called
"Resources".
These
resources
can
easily
be
assembled
into
working
systems
that
solve
real
world
clinical
and
administrative
problems
at
a
fraction
of
the
price
of
existing
alternatives.
FHIR
is
suitable
for
use
in
a
wide
variety
of
contexts
–
mobile
phone
apps,
cloud
communications,
EHR-based
data
sharing,
server
communication
in
large

healthcare
providers,

Why FHIR is better
FHIR
offers
many
improvements
over
existing

Interoperability
out-of-the-box–
base

be
used
as

also
be
adapted

FHIR offers many improvements over existing standards:
-
A strong focus on implementation – fast and easy to implement (multiple developers have had simple interfaces working in a single day)
-
Multiple implementation libraries, many examples available to kick-start development
-
Specification is free for use with no restrictions

A
central
challenge
for
healthcare
standards
is
how
to
handle
variability
caused
by
diverse
healthcare
processes.
Over
time,
more
fields
and
optionality
are
added
to
the
specification,
gradually
adding
cost
and
complexity
to
the
resulting
implementations.
The
alternative
is
relying
on
custom
extensions,
but
these
create
many
implementation
problems
too.
FHIR
solves
this
challenge
by
defining
a
simple
framework
for
extending
and
adapting
the
existing
resources.
All
systems,
no
matter
how
they
are
developed,
can
easily
read
these
extensions
and
extension
definitions
can
be
retrieved
using
the
same
framework
as
retrieving
other
resources.
In
addition,
each
resource
carries
a
human-readable
text
representation
using
html
as
a
fallback
display
option
for
clinical
safety.
This
is
particularly
important
for
complex
clinical
information
where
many
systems
take
a
simple
textual/document
based
approach.

Example
Resource:
Patient
Example Resource: Patient
This
simple
example
shows
the
important
parts
of
a
resource:
a
local
extension,
the
human
readable
HTML
presentation,
and
the
standard
defined
data
content.
FHIR
has
resources
for
administrative
concepts
such
as
patient,
provider,
organization
and
device
as
well
as
a
wide
variety
of
clinical
concepts
covering
problems,
medications,
diagnostics,
care
plans,
financial
concerns
and
more.

The
FHIR
development
process
The FHIR development process
FHIR
is
published
as
a
Draft
Standard
for
Trial
Use.
During
the
Trial
Use
phase,
HL7
actively
monitors
implementations
in
order
to
continue
to
improve
the
specification,
and
is
able
to
be
responsive
to
their
needs.
Due
to
the
many
advantages
FHIR
offers,
trial
use
is
already
beginning
right
now.
