Retrospective observational study identifies hearing thresholds and age affecting speech discrimination in adults, indicating intervention needs.

Evaluate speech discrimination in a primary care otolaryngology population and determine factors related to poor speech discrimination performance.
Retrospective observational study of 503 patients at a primary care otolaryngology clinic.
Pure-tone audiometry (PTA) and word recognition score (WRS) testing conducted.
Multivariable logistic regression analysis performed to identify associations with poor speech discrimination.
Poor speech discrimination found in 43 patients (8.9%).
Higher better ear PTA associated with poorer outcomes (OR 1.12 per dB increase; 95% CI 1.07–1.17; p < 0.001).
Older age also linked to poor speech discrimination (OR 1.09 per year increase; 95% CI 1.03–1.15; p = 0.003).
