Description of intervention(s) / exposure
Permanent childhood hearing loss impacts negatively on the speech, language, communicative, educational, and social developmental outcomes of children. This population-based study compares outcomes of children whose hearing loss was identified soon after birth to those of children identified later in a prospective manner. Children in NSW, Victoria and Queensland who presented for hearing services below 3 years of age at the national hearing service provider, Australian Hearing, were invited to participate in this study. About half of them had access to newborn hearing screening and the remaining did not. After enrollment, their speech, language and functional outcomes are being measured at fixed intervals over their first 10 years of life, and changes in their hearing status are monitored. These outcomes data will be related to a range of family, child and intervention characteristics. The effect of different factors, including age of intervention, on different outcomes will be quantified. The results will be used to guide best-practice intervention and monitoring of children following diagnosis.
