HL7
(Health
Level
7)
is
an
ANSI
standard
for
healthcare
specific
data
exchange
between
computer
applications.
It
is
widely
accepted
and
used
around
the
world
with
minor
modifications.
Need
of
HL7:
All
hospitals,
doctors,
and
other
healthcare
centres
around
the
world
require
the
ability
to
send
and
receive
healthcare
data,
including
patient
information
and
various
lab
reports.
As
a
result,
vast
amounts
of
healthcare
information
are
exchanged
on
a
daily
basis.
However,
medical
data
can
be
extremely
complicated
due
to
the
abundance
of
clinical
terminology,
as
well
as
the
structural
complexity
in
the
formation
of
the
presented
information.
Thus,
this
information
must
be
presented
in
a
standardized
format
in
order
to
ensure
that
the
data
is
universally
understood
and
organized.
The
language
that
has
been
developed
to
overcome
these
obstacles
is
HL7.
HL7
consists
of
grammar
and
vocabulary
that
is
standardized
so
that
clinical
data
can
be
shared
amongst
all
healthcare
systems,
and
easily
understood
by
all.
By
using
HL7
specifications
are
able
to
communicate
easily
with
one
another,
without
the
need
for
information
conversion.
Potential
Problems
with
existing
HL7
There
could
be
problems
with
HL7
if
vendors
do
not
strictly
adhere
to
the
HL7
standards.
There
could
be
more
problems
if
the
messages
are
not
constructed
properly
or
if
there
is
lack
of
specific
segments,
required
fields,
or
if
system
contains
unexpected
segments.
In
addition
to
this,
there
are
many
different
flavours
of
HL7,
which,
along
with
inconsistent
implementations,
result
in
complications
during
the
communications
process.
Systems
that
were
designed
to
handle
standard
HL7
messages
may
no
longer
be
able
to
do
so,
due
to
the
variations
in
message
formatting.
Our
services:
At
Cogniz
we
design
and
implement
HL7
from
scratch
according
to
your
specific
needs
and
if
one
system
is
already
there
we
can
help
it
run
smoothly
by
providing
proper
support,
maintenance
and
training.
We
use
messaging
tools
for
enabling
applications
to
communicate
and
bridge
the
gap
between
health
care
systems,
and
with
integration
services
we
can
optimise
message
routing
and
transformation
between
information
systems.
