Screening Strategy and Time Points for Newborn Hearing Re‐screening with High Risk Factors

Objective::To compare and analyze the pass rate and screening strategy of hearing rescreening for newborns with high risk factors.Methods::Retrospective chart review of high-risk newborns who failed their initial newborn hearing screen and subsequently underwent secondary hearing tests from June 2011 to June 2018 in Guangzhou Women and Children's Medical Center were performed.Results::Eight hundred and sixty-eight newborns with high risk factors were included in the study. The 57-70 days (83.5%) and 71-84 days (83.4%) group had the highest pass rate compared with 42-56 days (75.8%) and < 42 days (68.3%) group. As for different screening strategies, the pass rate of OAE(otoacoustic emissions), AABR (auto auditory brainstem response) and OAE + AABR was the highest in 57-70 days group and 71-84 days group, respectively. The OAE + AABR had the lowest pass rate compared to the other two modalities. When the pass rate was compared as different risk factors, the 57-70 days and 71-84 days group also had the highest pass rate compared with 42-56 days and < 42 days group and the pass rate had no significant differences among various risk factors group.Conclusion::Our results showed that all the pass rate of OAE, AABR and OAE+ AABR was the highest in 57-70 days group and 71-84 days group with significant difference, suggesting that the delayed screening time (>57 days) may increase the re-screening pass rate and reduce anxiety of parents, which is of great significance for clinical work.
