Factors impacting outcomes of cochlear implantation in children at two University centres in China: Multi-year analysis from the Paediatric Implanted Recipient Observational Study (P-IROS).

All participants demonstrated significant improvements in auditory performance and QoL over time. Younger age at CI, and bilateral/bimodal device fitting contributed to earlier improvements. Other potential factors that could help inform families, professionals, and health authorities about choice of hearing device and educational supports required included aetiology of hearing loss and level of maternal education.
