When infants are born with hearing loss, significant problems in infant and child development can occur if the loss is not detected and treated.
While there are many known risk factors for hearing loss, approximately 50% of infants with hearing loss have no known risk factors.1, 2, 3
Infants who are diagnosed early and receive appropriate interventions tend to have better language skills, social adjustment and behaviour scores, compared with children who receive services late.2
When population-based infant hearing screening is not in place, the average age of diagnosis for hearing loss is 24 months.
The evidence shows that screening all newborn infants for hearing loss is very effective.5,6,7 Based on this research, the U.S. Preventive Care Task Force has recommended that all newborn infants be screened for hearing loss.4 As a result of this, universal newborn hearing screening programs are widely implemented in the U.S., Europe and elsewhere. The U.S. recommendation is endorsed by many professional groups including the Canadian Paediatric Society.1
