Victorian Childhood Hearing Longitudinal Databank (VicCHILD)
The Victorian Childhood Hearing Longitudinal Databank (VicCHILD) is a Victorian register and research databank of children born with permanent hearing loss. VicCHILD ultimately aims to help children with permanent hearing loss reach their full developmental potentials.
Over 1200 families have already contributed data to VicCHILD. The information collected and stored will: help researchers and health professionals gain a better understanding of the causes and outcomes of childhood hearing loss; help researchers understand why some children with a hearing loss do well, while others face greater difficulties; and improve intervention and treatment.
The enrolment phase can occur at any age and time. Age-appropriate versions of questionnaires are used, and follow-up questionnaires and assessments are given (where possible) every few years after enrolment.

| Study focus |
To provide a register and population-based longitudinal research databank of Victorian children born with a permanent hearing loss to create a unique resource for advancing research in hearing loss. Specific objectives are to facilitate population-based research (including data linkage) that will describe secular trends in outcomes over time for repeated birth cohorts; support population-based quality improvement activities over time; identify and quantify biological and psychosocial factors that predict outcomes; and facilitate randomised controlled trials of new management and treatment approaches. |
| Sampling frame |
Since 2012, participants have been recruited via the Victorian Infant Hearing Screening Program (VIHSP). Retrospective recruitment was undertaken for babies born in the years 2005 to 2011 and prospective recruitment of babies born from 2012. All families whose child had been diagnosed with a permanent hearing loss were invited. Between 2012 - 2013, families who participated in a previous cohort with congenital hearing loss (SCOUT, born 2003 to 2004) were also invtied to participate. Since 2015, participants have also been recruited via the RCH Clinical Service (Caring for Hearing Impaired Children (CHIC) Clinic). |
