Analysis of Hearing Screening Results in 1 045 Newborns / 中国医科大学学报

ABSTRACT

Objective To evaluate factors influencing pass rates for newborn hearing screening under the same test conditions and using the same test methods.Methods Newborn hearing screening was carried out in 1 045 randomly selected newborns in Shengjing Hospital from January to June 2014.The newborns were screened at 2 days of age using transient evoked otoacoustic emissions (TEOAE).Related factors,including the number of embryos,birth weight,gestational age,gender,and mode of delivery were recorded.Data were analyzed using SPSS 19.0 software.Results Of 1 045 newborns,860 (82.3％) passed the hearing screening test and 185 failed.The number of embryos,ear-side tested,gestational age,and birth weight significantly influenced the pass rate using TEOAE.Term infants had a higher pass rate than premature ones (P ＜ 0.001).Heavier infants were more likely to pass (P =0.003).Right ears had a higher pass rate than left ears (P ＜ 0.001).Single babies had a higher pass rate than twins (P ＜ 0.001).Gender (P =0.361) and delivery mode (P =0.892) did not affect the pass rate.Conclusion The number of embryos,birth weight,gestational age,and ear-side tested affect newborn hearing screening results,but gender and mode of delivery show no significant effects on screening.
