  Objectives/Hypothesis
Previous research has shown hearing handicap to be reduced following hearing aid use or cochlear implantation in short-to-medium follow-up periods, yet the impact of interventions for hearing loss on hearing handicap in the long term remains understudied. This article reports hearing handicap at 6 months, 12 months, and 5 years after either hearing aid provision or cochlear implantation.

Study Design
Observational study.

Methods
A study of 115 participants from the Studying Multiple Outcomes after Aural Rehabilitative Treatment (SMART) study cohort assessed self-reported hearing handicap using the Hearing Handicap Inventory for the Elderly Screening version (HHIE-S) at baseline, 6 months, 12 months, and 5 years. Generalized estimating equations (GEE) were used to estimate the population mean HHIE-S score over time, accounting for the correlated nature of repeated measures data, and multiple imputation with chained equations was performed to impute missing data.

Results
Compared to baseline, mean HHIE-S scores after hearing aid provision were significantly reduced at 6 months (mean = −7.96, 95% confidence interval [CI]: −10.40, −5.53), 12 months (mean = −6.58, 95% CI: −9.26, −3.90), and 5 years (mean = −4.58, 95% CI: −7.87, −1.30). After cochlear implantation, mean hearing handicap scores were also significantly lower compared to baseline at 6 months (mean = −8.18, 95% CI: −11.07, −5.30), 12 months (mean = −10.04, 95% CI: −12.92, −7.16), and 5 years (mean = −8.97, 95% CI: −12.92, −7.16).

Conclusions
This study found short-term benefits from hearing aids and cochlear implantation on hearing handicap were maintained over 5 years.
