Questions
and Answers about the U.S. Preventive Services Task Force’s (USPSTF)
Recommendations for Newborn Hearing Screening
What is the
updated USPSTF recommendation for universal newborn hearing
screening?
In July 2008,
the USPSTF recommended screening for hearing loss in all newborn
infants. (Grade B recommendation). The USPSTF’s recommendation for
universal newborn hearing screening (UNHS) can be found at:
http://www.ahrq.gov/clinic/uspstf/uspsnbhr.htm.
What was
the previous USPSTF recommendation for universal newborn hearing
screening?
In 2001, the
USPSTF found good evidence that newborn hearing screening leads to
earlier identification and treatment of infants with hearing loss.
However, they concluded that there was not yet sufficient evidence
to determine whether earlier treatment resulting from screening led
to clinically important improvement in speech and language skills at
age three years or beyond for children with hearing loss that was
moderate to severe, permanent, bilateral and congenital. Therefore,
the USPSTF issued an “I” recommendation for UNHS.
Why did the
USPSTF change its recommendation from an “I” recommendation
(Insufficient evidence to recommend for or against screening) to a
“B” recommendation?
The USPSTF
updates its recommendations every five years or sooner if new
evidence becomes available that could substantially change a
recommendation. As new evidence became available for UNHS, the task
force reviewed that evidence and changed the recommendation to
reflect the improved health outcomes that had been demonstrated in
good-quality studies.
What does
this updated USPSTF recommendation mean for early hearing detection
and intervention (EHDI)?
Universal
newborn hearing screening, the first step in the EHDI process, is
regarded as the standard of care in the U.S., a standard backed by
other committees and policy making bodies such as the Joint
Committee on Infant Hearing (JCIH), the American Academy of
Pediatrics (AAP) and Healthy People 2010. In the past, critics of
UNHS had raised concern that there was not enough objective,
population-based scientific evidence showing the benefits of EHDI.
However, since the USPSTF bases its recommendations on such
evidence, this recent “B” recommendation could answer those concerns
and help further strengthen the rationale for EHDI among a broader
spectrum of pediatric clinical providers and policy makers.
What key
questions did the USPSTF address when making its 2008
recommendations?
Key Question
1. Among infants identified by universal screening that would not
be identified by targeted screening, does initiating treatment
before 6 months of age improve language and communication outcomes?
A good-quality
retrospective population-based study of children with hearing loss
indicated that children whose hearing loss was detected early as a
result of being born in hospitals with UNHS had better receptive
language at eight years of age than those who were born in hospitals
without UNHS. There was no significant difference in expressive
language or speech.
Key Question
2: Compared with targeted screening, does universal screening
increase the chance that treatment will be initiated by 6 months of
age for infants at average risk or for those at high risk?
A good-quality
nonrandomized controlled trial of a large birth cohort indicates
that infants identified with hearing loss through universal newborn
screening have earlier referral, diagnosis, and treatment than those
not screened. These findings are corroborated by multiple
descriptive studies of ages of referral, diagnosis, and treatment.
Key Question
3: What are the adverse effects of screening and early treatment?
When a child
fails a hearing screen, parent reactions may include worry,
uncertainty and distress, but these resolve for most parents. In
addition, one of the treatment options families can choose, cochlear
implants, has been associated with higher risks for bacterial
meningitis in young children. The cochlear implant model with the
highest risk of bacterial meningitis is no longer manufactured.
Questions
and Answers about the U.S. Preventive Services Task Force (USPSTF)
What is the
U.S. Preventive Services Task Force (USPSTF)?
The USPSTF is
the leading independent panel of experts in prevention and primary
care in the United States. It was convened by the U.S. Public
Health Service in 1984 and has been sponsored by the Agency for
Healthcare Research and Quality (AHRQ) since 1998.
What is the
role of the USPSTF?
The USPSTF
conducts rigorous, impartial assessments of the scientific evidence
for the effectiveness of a broad range of clinical preventive
services, including screening, counseling, and preventive
medications. Its recommendations are a primary, national reference
used by clinical care providers as they design their preventive
services.
Who are the
members of the U.S. Preventive Services Task Force (USPSTF)?
The USPSTF
consists of non-Federal experts in primary care, epidemiology, and
prevention. Throughout its existence, the task force has had at
least two pediatricians, as well as other pediatric health care
providers, among its members. At the time it issued its 2008
recommendation on universal newborn hearing screening, three of its
16 members were pediatricians, and a fourth was a pediatric nurse
practitioner
What are
the recommendations used by the USPSTF?
The USPSTF
considers both the potential net benefit of a particular service and
the degree of certainty that scientific evidence supports the
conclusion.
“A” – The
USPSTF recommends this service. There is high certainty the net
benefit of this service is substantial.
“B: - The
USPSTF recommends this service. There is high certainty that the
net benefit is moderate or there is moderate certainty that the net
benefit is moderate to substantial.
“C” - The USPSTF
recommends against routinely providing the service. There may be
considerations that support providing the service in an individual
patient. There is moderate or high certainty that the net benefit is
small.
“D” - The
USPSTF recommends against the service. There is moderate or high
certainty that the service has no net benefit or that the harms
outweigh the benefits.
“I” - The
USPSTF concludes that the current evidence is insufficient to assess
the balance of benefits and harms of the service. Evidence is
lacking, of poor quality, or conflicting, and the balance of
benefits and harms cannot be determined.
Who uses
U.S. Preventive Services Task Force (USPSTF) recommendations?
Primary care
clinicians are the principal audience for USPSTF recommendations.
Task Force recommendations have also influenced recommendations
developed by professional societies and have figured prominently in
the development of health care quality measures and national health
objectives.
