Abstract
Objective
To determine when infants in the neonatal intensive care unit (NICU) have the first hearing screen performed, and thus inform targeted testing for cytomegalovirus (CMV)-related hearing loss.
Study design
Retrospective review of electronic health records of infants admitted to a Level 4 outborn NICU and had a first hearing screen performed from 8/2016–8/2018.
Result
Among 1498 infants, 546 (36%) had a first hearing screen performed at age >21 days when a positive CMV PCR test cannot distinguish congenital from postnatal CMV acquisition. While most infants tested at >21 days of age were <34 weeks’ gestational age (71%), 18% (n = 100) and 11% (n = 59) were ≥34 and ≥37 weeks’ gestation, respectively.
Conclusion
Targeted CMV testing for failed hearing screen in the NICU is problematic as 36% of infants did not have a hearing screen performed before 21 days of age, supporting the need for CMV screening at NICU admission.
