Impact and cost-effectiveness evaluation of a community-based rehabilitation intervention on quality of life among Chinese adults with hearing loss: study protocol for a randomized controlled trial.

Background: Hearing loss is quite prevalent and can be related to people's quality of life. To our knowledge, there are limited studies assessing the efficacy of hearing interventions on quality of life in adults. Therefore, we aim to conduct a randomized controlled trial (RCT) to determine the impact and cost-effectiveness of community-based hearing rehabilitation on quality of life among Chinese adults with hearing loss.
