A Swiss study group was formed in summer 1998 with the aim of establishing a universal hearing screening programme in newborns following the recommendations of the "European Consensus Statement on Neonatal Hearing Screening" (Milan 1998). The aim of the group was to standardise and to introduce universal hearing screening in all infants born in Switzerland. Starting in June 1999, several hospitals in Switzerland began the screening programme using commercially available equipment for easy and highly automated measurement of transient evoked otoacoustic emissions. Up to March 2000, 6262 children were born in these hospitals and 5656 (90%) underwent neonatal hearing screening. 88 children of the 5656 did not pass the screening test. The measurement of otoacoustic emissions was repeated in a follow-up examination within 6 weeks. If otoacoustic emissions were again absent, evoked auditory brainstem potentials were measured. 48 children were found to have hearing within normal limits at the follow-up examination, 24 children have not been examined yet, 11 children were examined in other clinics or the follow-up examination was refused by the parents. 5 children were found to have bilateral hearing dysfunction and were referred to rehabilitation within the first 6 months of life.
