Abstract
AbstractObjectiveTo determine the positivity rate of congenital cytomegalovirus (cCMV) testing among universal, hearing‐targeted CMV testing (HT‐cCMV) and delayed targeted dried blood spot (DBS) testing newborn screening programs, and to examine the characteristics of successful HT‐cCMV testing programs.Study DesignProspective survey of birth hospitals performing early CMV testing.SettingMultiple institutions.MethodsBirth hospitals participating in the National Institutes of Health ValEAR clinical trial were surveyed to determine the rates of cCMV positivity associated with 3 different testing approaches: universal testing, HT‐cCMV, and DBS testing. A mixed methods model was created to determine associations between successful HT‐cCMV screening and specific screening protocols.ResultsEighty‐two birth hospitals were surveyed from February 2019 to December 2021. Seven thousand six hundred seventy infants underwent universal screening, 9017 infants HT‐cCMV and 535 infants delayed DBS testing. The rates of cCMV positivity were 0.5%, 1.5%, and 7.3%, respectively. The positivity rate for universal CMV screening was less during the COVID‐19 pandemic than that reported prior to the pandemic. There were no statistically significant drops in positivity for any approach during the pandemic. For HT‐cCMV testing, unique order sets and rigorous posttesting protocols were associated with successful screening programs.ConclusionRates of cCMV positivity differed among the 3 approaches. The rates are comparable to cohort studies reported in the literature. Universal CMV prevalence decreased during the pandemic but not significantly. Institutions with specific order set for CMV testing where the primary care physician orders the test and the nurse facilitates the testing process exhibited higher rates of HT‐cCMV testing.
