||Senior Research Scientist, National Acoustic Laboratories, Australia
Teresa YC Ching, PhD is head of Rehabilitation Procedures research at the National Acoustic Laboratories, Australia. Her current research focuses on investigating efficacy of early intervention for populations of children with bilateral hearing loss or unilateral hearing loss, identifying factors affecting outcomes, evaluation of sound detection and discrimination in infants with hearing loss or auditory neuropathy spectrum disorder using cortical auditory evoked potential (CAEP) measurements and parental reports, and prescription of hearing aids and electric-acoustic stimulation (bimodal fitting) for children and adults. Teresa has published more than 120 peer-reviewed manuscripts. Key contributions from her original research findings include a validated test of functional performance; evidence-based protocols for bimodal fitting, pediatric referral for cochlear-implant-candidacy, CAEP and functional assessments for management of permanent childhood hearing impairment; and methods for predicting language outcomes of infants with hearing loss. She is regularly invited to deliver key note presentations at international conferences. She serves on the editorial boards of three international journals.

Abstract: Permanent childhood hearing loss has a major negative impact on children's developmental outcomes, at high societal costs. Despite the widespread implementation of universal newborn hearing screening (UNHS), there was no high-quality evidence on the effectiveness of early intervention for improving language outcomes, at a population level. To address the evidence gap, we conducted the Longitudinal Outcomes of Children with Hearing Impairment (LOCHI) study (www.outcomes.nal.gov.au).
Methods: The study includes about 450 children born with hearing loss between 2002 and 2007 in New South Wales, Queensland and Victoria in Australia. They were diagnosed through either UNHS or standard care, but received the same post-diagnostic, free, expert audiological services. The children's outcomes were assessed at multiple intervals.
Results and Discussion: The measurements by 5 years of age demonstrated a clear advantage of early intervention for improving language outcomes, at a population level. Early functional performance measured by the PEACH was a significant predictor of language outcomes at 5 years.
Conclusions: By streamlining clinical pathways for children with hearing loss to ensure early fitting and early referrals for cochlear implants, many more children with congenital hearing loss will have access to the same life-opportunities as would be available to typically developing children.

Developing an evidence base for the management of children with unilateral hearing loss: the CUHL study
Saturday 9 July | 9.00am
Despite early detection of congenital unilateral hearing loss (UHL) via universal newborn hearing screening (UNHS), there is a lack of evidence on the efficacy of early intervention (in the form of device fitting) for improving outcomes; and the benefits vs harms of early detection and treatment is uncertain. Consequently, there is clinical equipoise concerning whether children should receive amplification (as well as surveillance).
In this lecture, the current status of evidence will be reviewed, and findings from a survey of clinicians will be presented. Under the HEARing CRC, NAL is conducting a prospective study to investigate the efficacy of early fitting on outcomes of children with unilateral hearing loss (the CUHL study). In parallel, we are also conducting a retrospective study to assess outcomes of children with unilateral hearing loss at school age, and to identify factors influencing their outcomes. We have launched the CUHL website (www.cuhl.nal.gov.au), where we provide resources for families and professionals. The studies will contribute to evidence-based management of childhood unilateral hearing loss in future.
