An observational study in Hearing Loss, Noise-Induced, sponsored by Assuta Medical Center. Completed at 1 site in Israel. Per ClinicalTrials.gov, last updated 2026-09-02.
Sponsored by Assuta Medical Center · Observational
Hearing loss and tinnitus can affect communication, employment, daily functioning, and long-term disability. This study will examine hearing-related disability claims recorded by the National Insurance Institute of Israel between 2018 and 2025. The study will evaluate changes over time in the number and proportion of hearing-related claims and will compare patterns between general disability and work-injury claims. It will also describe the main hearing-related diagnoses, including hearing impairment, tinnitus, sensorineural hearing loss, noise-induced hearing loss, and acoustic trauma, as well as the levels of disability assigned according to national disability regulations. The study uses existing administrative records and does not involve any intervention or change in patient care. The aim is to improve understanding of the national burden and long-term consequences of hearing-related disorders and to identify trends that may support prevention, occupational health, and disability-policy planning.

Counted across the registry records on this site, refreshed daily.
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.

Exclusion Criteria:
Individuals with hearing-related claims recorded by the National Insurance Institute of Israel between 2018 and 2025 will constitute the study cohort. The cohort will include persons with diagnoses such as hearing loss, tinnitus, sensorineural hearing loss, noise-induced hearing loss, and acoustic trauma. Claims will be analyzed according to benefit stream, including general disability and work-injury claims. Demographic, diagnostic, temporal, and disability-related characteristics will be evaluated where available. No intervention or treatment is assigned as part of this retrospective observational study.
Proportion of Hearing-Related Claims Among All Disability Claims
The proportion of hearing-related claims will be calculated as the number of claims associated with hearing loss, tinnitus, or other hearing-related diagnoses divided by the total number of claims within each benefit stream. Annual trends will be evaluated separately for general disability and work-injury claims.
Time frame: 2018-2025
Plan to share: No — Individual participant data will not be shared because the study is based on confidential administrative records held by the National Insurance Institute of Israel. The investigators do not have authorization to distribute individual-level data outside the approved research framework. Aggregated, de-identified study results may be reported in publications and presentations.
