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) 2090–2093

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.
