initialpopulation  Initial Population 
The
initial
population
refers
to
all
patients
or
events
to
be
evaluated
by
a
quality
measure
involving
patients
who
share
a
common
set
of
specified
characterstics.
All
patients
or
events
counted
(for
example,
as
numerator,
as
denominator)
are
drawn
from
the
initial

numerator  Numerator 
The
upper
portion
of
a
fraction
used
to
calculate
a
rate,
proportion,
or
ratio.
Also
called
the
measure
focus,
it
is
the
target
process,
condition,
event,
or
outcome.
Numerator
criteria
are
the
processes
or
outcomes
expected
for
each
patient,
or
event
defined
in
the
denominator.
A
numerator
statement
describes
the
clinical
action
that
satisfies
the
conditions
of
the

numeratorexclusion  Numerator Exclusion 
Numerator
exclusion
criteria
define
patients
or
events
to
be
removed
from
the
numerator.
Numerator
exclusions
are
used
in
proportion
and
ratio
measures
to
help
narrow
the
numerator
(for
inverted

denominator  Denominator 
The
lower
portion
of
a
fraction
used
to
calculate
a
rate,
proportion,
or
ratio.
The
denominator
can
be
the
same
as
the
initial
population,
or
a
subset
of
the
initial
population
to
further
constrain
the
population
for
the
purpose
of
the

denominatorexclusion  Denominator Exclusion 
Denominator
exclusion
criteria
define
patients
or
events
that
should
be
removed
from
the
denominator
before
determining
if
numerator
criteria
are
met.
Denominator
exclusions
are
used
in
proportion
and
ratio
measures
to
help
narrow
the
denominator.
For
example,
patients
with
bilateral
lower
extremity
amputations
would
be
listed
as
a
denominator
exclusion
for
a
measure
requiring

denominatorexception  Denominator Exception 
Denominator
exceptions
are
conditions
that
should
remove
a
patient
or
event
from
the
denominator
of
a
measure
only
if
the
numerator
criteria
are
not
met.
Denominator
exception
allows
for
adjustment
of
the
calculated
score
for
those
providers
with
higher
risk
populations.
Denominator
exception
criteria
are
only
used
in
proportion

measurepopulation  Measure Population 
Measure
population
criteria
define
the
patients
or
events
for
which
the
individual
observation
for
the
measure
should
be
taken.
Measure
populations
are
used
for
continuous
variable
measures
rather
than
numerator
and
denominator

before
determining
the
outcome
of
