RESUMO
CONCLUSIONS: The results show that the fitting of a contralateral hearing aid (HA) in the non-implanted ear of cochlear implant (CI) recipients is now well established as standard clinical practice. However, there is a lack of experience in HA fitting within the CI centres and the use of published bimodal fitting procedures is poor. The HA is often not refitted after CI switch-on and this may contribute to rejection. Including a bimodal fitting prescription and process in the CI fitting software would make applying a balancing procedure easier and may increase its implementation in routine clinical practice. OBJECTIVE: This survey was designed to investigate and understand the current approach to bimodal fitting of HAs and CIs across different countries and the recommendations made to recipients. METHODS: Clinicians working with HAs and/or CIs were invited to participate in an international multicentre clinical survey, designed to obtain information on the various approaches towards bimodal hearing and CI and HA device fitting. Forty-one questions were presented to clinicians in experienced CI centres across a range of countries and answers were collected via an online survey. RESULTS: In all, 65 responses were obtained from 12 different countries. All clinicians said they would advise a CI user to wear a contralateral HA if indicated. However, a significant number (45%) had either never fitted HAs before or had less than 1 year of experience. In general, there were no specific criteria for selecting candidates to fit with an HA. A strategy to balance the HA with the CI was not used as a standard practice for any of the adults and was used in only 12% of the children. Only half the respondents were aware of the bimodal literature. The majority of professionals (18/30) did not refit the HA after CI switch-on. However, if users complained of sound quality or loudness issues or had poor test results, a follow-up session was provided. The main benefit reported by recipients was improvement in overall sound quality.
