Evaluation of decision criteria of CI candidates for implant system selection

Cochlear implants (CIs) are a common therapy for severe to profound hearing loss. In the absence of additional medical requirements, patients may choose freely between different implant systems. Therefore, a detailed and best possible counselling is required. The aim of the study was the evaluation of decision criteria of CI patients that are rated as relevant during the selection of the CI device. The evaluation was carried out via questionnaires at different time points: 1) before implantation, 2) after completion of the first fitting and 3) after 6 months CI experience. Among others, the questionnaires for decision criteria included characteristics of the implant, sound processor, accessories and different hearing program parameters. The relevance of the particular aspects for choosing an implant system was assessed using Likert scaling with four levels (very important to unimportant). The results showed that the reliability of the implant and the wearing comfort of the sound processor were rated as “very important” (98.3 %  /97.5 % ). The possibility of noise reduction was also considered as “very important” (95.2 % ). Also high priority with rating as “important” was observed for MRI safety (58.5 % ) and directional microphone technology (65.8 % ). The availability of processor buttons was reviewed as being “rather unimportant” (19.5 % ) as well as swimming protection (41.5 % ). Furthermore, the data showed that the patients’ assessment criteria almost stayed the same after 6 months of CI usage. With the findings of the study, the counselling process shall be optimized. Therefore, aspects that appear most important for the device selection will be considered more intensive. However, the content of patient counselling needs to respect individual requirements.
