Longitudinal Outcomes of Children with Hearing Impairment (LOCHI)

The study aims to examine the effectiveness of early intervention (and other factors) on the developmental outcomes of children with permanent hearing loss at 16-17 years of age and to evaluate the cost-effectiveness of early intervention. LOCHI has published valuable insights since 2009 and is a world-renowned longitudinal project.

The LOCHI study is a population-based longitudinal study that prospectively evaluates the development of a group of Australian children with hearing loss as they grow up. This study is unique in its inclusion of children whose hearing loss was diagnosed through either Universal Newborn Hearing Screening (UNHS), or standard care; and all of whom access the same post-diagnostic services provided by the national audiological service provider, Australian Hearing. This means that their results can be fairly compared, whenever and wherever their hearing loss was discovered.
