Research In Profile

The research in the Pediatric Audiology Strategies and Systems Laboratory focuses on policy and practice integration for infant and child hearing. Evidence-based clinical protocol development and implementation for infants and children who have permanent hearing loss are key activities. Standardization of universal newborn hearing screening, audiological surveillance of children with hearing loss risk factors, pediatric audiology assessment and hearing aid fitting as well as outcome measures and language development services guide the implementation of infant hearing health care services. Through these activities, professor Bagatto consults for various provincial early hearing loss detection and intervention programs in Canada to develop and implement clinical protocols and program policies. She is also the Chair of the Canadian Infant Hearing Task Force that advocates for infant hearing health care across the country.
