OBJECTIVE: The aim of this study was to determine whether universal newborn hearing screening (UNHS) is effective in increasing the number of children whose hearing impairment is detected early, i.e. within the first 6 months of life. It also investigated whether UNHS contributes most to the early detection of moderately and severely hearing-impaired newborns, as suggested by a recently published report. METHODS: The study consisted of a retrospective analysis of the data of all children born in Tyrol between 1980 and 1999 and having an at least moderate permanent hearing loss in the better ear. RESULTS: The findings are that since UNHS was introduced in some newborn nurseries in 1995, a substantially higher number of hearing-impaired children has been detected early. For the whole sample, the increase of the early detection rate is 39.9%, with a 95% confidence interval of 33.2-46.8% (P<0.0001). For moderate hearing loss the increase is 49.2 with a 95% confidence intervall of 39.6-58.8% (P=0.000). CONCLUSIONS: On the whole, our findings lend support to the view that UNHS is effective in early detection of congenital hearing impairment. We conclude that UNHS provides the greatest benefit for moderately hearing-impaired children who, otherwise, would have been detected last.
