- Design
- Implementation study with retrospective outcome review
- Population
- 50,438 live births in one US health system; 7,491 screened
- Primary outcome
- Detection of congenital CMV and follow-up
- Effect
- 34 cases (0.45%); ~2.5-fold rise in detection; targeted 0.74% vs universal 0.33%
A Pediatrics report (21 September) describes Cleveland Clinic's hybrid congenital CMV screening programme: universal screening in neonatal intensive care, targeted screening in newborn nurseries (for example after a failed hearing screen). Between 2022 and 2025, 7,491 of 50,438 infants (14.9%) were tested, up from about 150 a year to more than 2,000.
Thirty-four infants (0.45%) had confirmed congenital CMV, about 2.5 times the previous detection. Targeted screening had a higher yield than universal NICU screening (0.74% vs 0.33%). Abnormal neuroimaging (32.3%) and small for gestational age (26.5%) were the commonest findings. Audiology follow-up was limited by logistics, family resources and understanding.
The timing matters: antiviral treatment for symptomatic congenital CMV is started within the first month, so a diagnosis has to be made early. A screen without follow-up does not deliver the benefit.
- Test for CMV (saliva or urine PCR) within 21 days in any baby failing the newborn hearing screen
- Consider testing small-for-gestational-age babies and those with microcephaly or unexplained jaundice
- Refer confirmed cases promptly for assessment and discussion of antiviral treatment
- Arrange audiology follow-up before discharge and confirm the family can attend
Why it matters
Congenital CMV is the commonest non-genetic cause of childhood deafness and is found only if it is looked for early.
Don't overread it
This is a single-system implementation report, not a trial of outcomes after screening.
The statistics, in plain English
Detection of 0.45% among those tested reflects who was selected for testing, not population prevalence. The difference between targeted and universal groups (P = .01) shows that selecting on risk finds more cases per test.
