RESUMEN
OBJECTIVE: This study interviewed youth with unilateral hearing, utilizing their responses to generate candidate items for a condition-specific patient-reported instrument. STUDY DESIGN: Mixed methods, cross-sectional. SETTING: Tertiary care children's hospital. PARTICIPANTS AND METHODS: Youth with unilateral hearing loss and normal hearing in the contralateral ear were identified and recruited for participation through query of an audiometric database and through hearing loss clinics. Interviews with the youth were qualitatively analyzed to identify common themes and generate items related to functional impact. A multi-institutional expert panel reviewed items with prespecified item selection criteria. Participants rated items for impact on daily life. For preliminary criterion validity assessment, statistical analyses explored correlations between functional scores and type and severity of hearing loss. RESULTS: Thirty-nine youth aged 9 to 18 years with unilateral hearing loss participated; 31% used a hearing device. Fifteen youth participated in interviews; thematic analysis, item crafting, and expert panel item review resulted in 41 items. Twenty-six youth responded to the items, reporting low functional scores in the domains of sound localization, ear positioning, and noise environment. They reported better levels of function in carrying out group conversations, focusing on schoolwork, and feeling safe during activities. Multivariate linear regression found that youth scored 0.4 points (or approximately 8%) lower on the functional impact scale with every 20-dB HL increase in pure tone average in the abnormal ear. CONCLUSION: Youth with unilateral hearing loss report functional impact, particularly related to sound localization, ear positioning, and noise environment; therefore, they may benefit from a condition-specific functional assessment instrument.
RESUMEN
OBJECTIVE: Management of children with unilateral hearing loss is not standardized. The primary goal of this study was to elicit patient- and parent-reported perspectives regarding usage of hearing devices in pediatric UHL and to suggest a basic algorithmic approach to management. METHODS: Our tertiary care center recruited families of youth ages 5-19 years with unilateral hearing loss from January 2014 through October 2015. Parents of all youths completed a 36-item survey, and some youth ages 11-19 years participated in hour-long interviews. We assessed patterns of hearing device usage among participants, and performed qualitative data analysis to understand factors considered by youths when deciding whether or not to use a hearing device. RESULTS: Survey information was collected for 50 patients. Distribution of hearing loss severity in affected ear was mild 14%, moderate 26%, severe 22%, and profound 38%. The majority of children had sensorineural hearing loss (57%), followed by mixed (32%), and then conductive (11%). 34 children (68%) had tried a hearing device; 20 continued to use the device. Retention rates were similar among children with different degrees of hearing loss: mild 66%, moderate 50%, severe 60%, profound 64%. Sixteen children tried a wireless contralateral routing of signal (CROS) device, and 15 tried a behind-the-ear (BTE) hearing aid. Retention rates for CROS and BTE devices were 69% and 47%, respectively. The most common reason for cessation of use was discomfort, followed by lack of benefit. CONCLUSION: A majority of children with unilateral hearing loss who tried a hearing device continued to use it, and retention rates were similar across all degrees of hearing loss. These findings suggest that personal hearing devices should be included in management protocols.
