- Design
- Cross-sectional comparison of two national surveys
- Population
- 12,756 US adults aged 55 and over screened; 2,552 with audiometry
- Primary outcome
- Prevalence of hearing loss in the better ear
- Effect
- 54.8% (95% CI 53.7 to 56.0) by screener vs 54.5% (51.1 to 57.8) by audiometry
A cross-sectional analysis in Otolaryngology–Head and Neck Surgery (published 29 September) used a handheld hearing screener in 12,756 US adults aged 55 and over from a national ageing study, and compared the results with pure-tone audiometry in a separate national survey.
Hearing loss in the better ear was present in 54.8% by the screener, almost identical to the 54.5% found by audiometry at a 20 dB threshold. Mild difficulty affected about 49%, and moderate to severe difficulty about 6%, again closely matching audiometric categories.
Two practical points follow. Hearing loss in older adults is the norm rather than the exception, and it is linked to social isolation and cognitive decline, yet is often not asked about. And a simple screening device gave population estimates that agreed with formal audiometry, which supports its use where an audiologist is not at hand. Audiometry remains the standard for diagnosis and fitting.
- Ask adults aged 55 and over about hearing difficulty at routine reviews.
- Consider a simple screening tool in clinic where audiometry is not immediately available.
- Refer people who screen positive for formal audiometry before hearing aid fitting.
- Treat moderate or worse hearing loss as a priority for rehabilitation, given its link with isolation and cognitive decline.
Why it matters
A condition affecting over half of older adults is still rarely asked about in routine care.
Don't overread it
The screener's agreement was shown at population level, not for diagnosing individual patients.
The statistics, in plain English
The prevalence estimates from the two surveys differed by less than half a percentage point, and the p-values above 0.7 mean no detectable difference between methods. That agreement is between populations, not a measure of how accurate the screener is for one person.
