The majority of infants diagnosed with a target hearing loss (bilateral, permanent, moderate or greater degree) following newborn hearing screening in Victoria reach the benchmarks of being screened by one month of age, diagnosed by three months of age, and engaged in intervention by six months of age. This project aimed to investigate explanations for why some infants with target hearing loss do not reach these benchmarks.
The VIHSP databases were interrogated to establish the ages at which infants with target hearing loss, completed screening, diagnosis and commencement of intervention. Records of infants who fell outside the benchmarks were reviewed to ascertain contributing factors.
Of the 155,286 babies screened in Victoria born in 2014 and 2015, 1597 were referred to diagnostic audiology, and 129 were diagnosed with a target hearing loss.
Of these 129, twenty three infants had their second screen after one month of age, twenty seven were diagnosed later than three months of age, nineteen were first fitted with hearing aids after they were six months of age, and thirty commenced early intervention after the age of six months.
While prematurity contributed to delays in 54% of babies where the benchmarks were not met, there are a number of other, potentially modifiable, factors leading to delays.
While there is limited capacity to alter some of the baby and family factors that may lead to delays in the detection and intervention pathway, there are opportunities for improvement in systems issues to minimise delays.
