Trial Outcomes & Findings for Cochlear Implantation in Pediatric Cases of Unilateral Hearing Loss (NCT NCT02963974)

NCT ID: NCT02963974

Last Updated: 2021-08-06

Results Overview

Recorded, open set word recognition presented pre-operatively in the soundfield when using a traditional hearing aid (contralateral ear masked) and at 3-, 6-, 9-, 12-, 18-, and 24-month post-activation intervals by direct input to the speech processor using the Consonant-Nucleus-Consonant (CNC) words. Scores are reported as percent words correct and a higher score is better. Change is measured from the pre-operative to the 3-month post-activation interval, and from the 3-month post-activation interval to each subsequent interval.

Timeframe: 3 months post-activation

Soundfield localization of 200-ms speech-shaped noise, presented from 11 speakers at 70 decibel (dB) sound pressure level (SPL) in a sound treated room. Error measures are made device on and device off after 3 months of device use. Overall root-mean-square (RMS) error is the difference between the sound source azimuth and the response azimuth and a lower score indicates more accurate localization of the sound source. Random error is the average of the standard deviation of the responses for each source and a lower score reflects a more consistently accurate response. Constant error is a measure of side bias, and a lower score indicates less response bias to either side. Adjusted constant error is a measure of reliability in the response taking side bias into account, and a lower score indicates a more reliable response.

The Speech Spatial Qualities Questionnaire requires participants to rate their perceived hearing ability for 49 scenarios using a 10-point scale, ranging from 0 (Not at all) to 10 (Perfectly). A score higher than 0 for each listening scenario shows some benefit of the device, while a score of 10 indicates the device was extremely beneficial. The SSQ questionnaire assesses performance in 3 domains, hearing speech in quiet and noise environments (9 items), spatial or directional hearing (5 items) and sound qualities (8 items). Domain scores represent an average of item ratings, therefore each domain score ranges from 0 to 10 with a higher score indicating a better outcome. The pediatric version of this test was used and parents reported as proxy pre-operatively and at at 3-, 6-, 9-, 12-, 18-, and 24-month post-activation intervals. Change is measured from the pre-operative to the 3-month post-activation interval and between the 3-month interval to all subsequent intervals.

Bern SSD Questionnaire is a 10-item questionnaire used for rating perceived benefit of a hearing technology designed to be used for persons with Unilateral Hearing Loss (UHL). A positive score indicates greater perceived ability with the device and a negative score indicates greater perceived ability without the device. Scores range from -5 meaning much easier listening without the hearing device to +5 indicating much easier listening with the device. Scores across all 10 items are averaged for a single score. A modified version of this test that can be completed by a parent was used pre-operatively and at 3-, 6-, 9-, 12-, 18-, and 24-month post-activation intervals. Change is measured from the pre-operative to the 3-month post-activation interval and from the 3-month interval to each subsequent interval.

PedsQL Multidimensional fatigue scale is a validated scale for determining fatigue in young children, including general fatigue, sleep/rest fatigue and cognitive fatigue. Scores from this test have been previously demonstrated to be substantially affected by hearing loss in children. A parent report version was used pre-operatively and at 3-, 6-, 9-, 12-, 18-, and 24-month post-activation intervals. Items are scored on a 5-point Likert scale and are then reversed scored and linearly transformed to a 0-100 scale where 100 would indicate no fatigue and 0 would indicate near constant fatigue.
