Is hearing loss becoming a bigger cause of disability? a national study digs into the data
NCT ID NCT07798687
First seen Sep 01, 2026 · Last updated Sep 03, 2026 · Updated 2 times
Summary
This study looks at disability claims in Israel from 2018 to 2025 to see if hearing-related disabilities are becoming more common. Researchers will compare general disability claims with work-injury claims and describe the main diagnoses, such as hearing loss, tinnitus, and noise-induced hearing damage. The study uses existing records and does not involve any treatment. The goal is to understand the national burden of hearing problems and support better prevention and policy planning.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If the trends are clear, this could guide prevention efforts and disability policy to reduce the burden of hearing loss.
- What could go wrong
- This is an observational study using existing records, so it cannot prove causes. Trends may reflect changes in reporting or regulations rather than actual hearing loss rates.

Who is studied
Individuals whose administrative records were included in the National Insurance Institute of Israel database between January 1, 2018 and December 31, 2025. The study population includes persons with hearing-related diagnoses or disability determinations, including hearing loss, tinnitus, sensorineural hearing loss, noise-induced hearing loss, and acoustic trauma. Analyses will focus primarily on general-disability and work-injury benefit streams. Because this is a retrospective study of existing administrative records, no participants will be prospectively enrolled and no study intervention will be performed.
