Short-term hearing aid benefit in a large group.

Area of Science:

• Audiology
• Rehabilitation medicine
• Medical technology

Background:

• Hearing loss affects millions, impacting communication and quality of life.
• Hearing aids are a common intervention, but objective outcome measures are crucial.
• Assessing patient-perceived benefits effectively guides treatment and device selection.

Purpose of the Study:

• To evaluate the short-term effectiveness of hearing aid treatment using a revised Self-Assessment of Communication (SAC-Hx) questionnaire.
• To assess the impact of hearing aid use on self-perceived communication abilities in a large cohort of veterans.
• To determine if prior hearing aid experience or hearing loss severity influences treatment benefit.

Main Methods:

• A cohort of 4,584 veterans with adult-onset sensorineural hearing loss (mild to severe) were fitted with hearing aids.
• The revised Self-Assessment of Communication (SAC-Hx) was administered before and 6 weeks after hearing aid fitting.
• Benefit was quantified as the change in SAC-Hx scores, analyzed against hearing loss characteristics and user experience.

Main Results:

• Hearing aid treatment yielded statistically significant improvements in all communication categories assessed by the SAC-Hx.
• New hearing aid users experienced the greatest benefit, but previous users also reported significant gains.
• Benefit magnitude was comparable across different durations of hearing aid experience.
• Perceived communication difficulties correlated with hearing impairment severity and poorer word recognition scores.
• Functional benefits were observed across all hearing loss severity levels (normal to profound).

Conclusions:

• The revised Self-Assessment of Communication (SAC-Hx) is a feasible and efficient tool for assessing hearing aid outcomes.
• Hearing aid treatment provides robust, statistically significant benefits for veterans with diverse hearing loss profiles.
• Understanding user experience and hearing loss characteristics can further refine hearing aid fitting and rehabilitation.
