1. Introduction
Cytomegalovirus
(CMV)
is
the most common
infectious cause of
congenital
sensorineural
hearing
loss
(SNHL)
[1]
. Morton
et
al.,
Grosse et al., and our group have
reported
that 15–30% of pediatric
hearing
loss
can be
attributed
to CMV
[2–4]
.
The
consequences
of
hearing
loss
for
affected
children
include
speech
and
language
delay,
low
education,
and
poor
occupational
performance
in
adulthood
[5]
.
The
lifetime
cost
for
each
child with hearing
loss
is
estimated
to
be
over
three
hundred
thousand
dollars
accounting
for
the
lost productivity,
the need
for
special education, vocational
rehabilitation,
assistive
devices
and medical
costs
[6]
. One
study
estimates
the
total costs associated with congenital CMV
infection
to
be
$4
billion
a
year
[7]
.
Preventing
the
sequelae
of
progressive
hearing
loss would
significantly
reduce
the
personal
and
societal
costs
for
these
children.
Research
has
shown
that
early
identification
and
intervention
before
the
hearing-impaired
infant
reaches
6 months
of
age
are
associated
with
better
language
outcomes
[8,9]
.
A
recent
paper
also
reported
that
early
antiviral
intervention may
improve CMV-
related
hearing
and
neurocognitive
outcomes
[10]
.
The
National
Institute
of
Allergy
and
Infectious Disease
Collaborative
Antiviral
Study Group
(CASG) presented
results comparing 6 weeks versus 6
months
of
oral
valganciclovir
(VGC)
therapy
for
CMV
infected
children
less
than
one
month
of
age.
Specifically,
64%
of
the
children who underwent 6 weeks of VGC
therapy had
improved or
normal hearing
versus 77% who underwent 6 months
of
oral VGC
therapy.
These
better
audiologic
and
neurocognitive
outcomes
apply
to
symptomatic
congenitally
infected
infants, however,
and
may
not
apply
to
the
CMV
infected
hearing
impaired
infants
identified
from
a
hearing
targeted
early
CMV
approach
[10]
.
A
critical
challenge
in
diagnosing
congenital
CMV
is
that most
newborns do not present with any signs of
infection. The diagnosis
requires
laboratory
testing
of
neonatal
samples
within
the
first
three weeks of
life
since postnatal CMV
infection
is not
associated
with
SNHL. Thus,
ideally,
at-risk
infants
should be
identified
early
to
permit
targeted monitoring
and
intervention
so
that
they
can
achieve
normal
speech
and
language
skills. One
testing
approach
utilizes
a
targeted
hearing
loss
driven
screening
method
to
determine
which
infants
should
undergo
CMV
testing.
This
approach became
the basis of a bill Representative Ronda Menlove,
with the support of the Utah CMVworking group,
introduced
to the
International Journal of Pediatric Otorhinolaryngology 79 (2015) 2090–2093A

Objectives:
In
this study, we estimate an
ex ante
cost–benefit analysis of a Utah
law directed at
improving
early
cytomegalovirus
(CMV)
detection.
Study design:
We use
a differential
cost of
treatment
analysis
for publicly
insured CMV-infected
infants
detected
by
a
statewide
hearing-directed
CMV
screening
program.
Methods:
Utah government administrative data and multi-hospital accounting data are used
to estimate
and
compare
costs
and
benefits
for
the Utah
infant
population.
Results:
If
antiviral
treatment
succeeds
in mitigating
hearing
loss
for
one
infant
per
year,
the
public
savings will
offset
the
public
costs
incurred
by
screening
and
treatment.
If
antiviral
treatment
is
not
successful,
the
program
represents
a
net
cost,
but
may
still
have
non-monetary
benefits
such
as
accelerated
achievement
of
diagnostic milestones.
Conclusions:
The
CMV
education
and
treatment
program
costs
are
modest
and
show
potential
for
significant
cost
savings.
