Methods for screening for hearing loss in older adults

Area of Science:

• Gerontology
• Audiology
• Primary Care Medicine

Background:

• Hearing loss is a prevalent condition in older adults, impacting quality of life.
• Early detection through screening is crucial for timely intervention.
• The Hearing Handicap Inventory for the Elderly-Screening Version (HHIE-S) and Audioscope are common screening tools.

Purpose of the Study:

• To compare the diagnostic accuracy of the Audioscope and HHIE-S for detecting hearing loss in elderly patients.
• To assess patient preference between the two screening methods.

Main Methods:

• 185 patients over 60 years old underwent screening with both Audioscope and HHIE-S.
• Pure tone audiometry served as the reference standard for hearing loss.
• Three criteria were used to define hearing loss: Speech Frequency PTA > 25 dB, High Frequency PTA > 25 dB, and Ventry & Weinstein criteria.

Main Results:

• Audioscope demonstrated superior performance with higher sensitivities (0.64-0.96 vs. 0.29-0.63) and positive likelihood ratios (4.86-7.52 vs. 2.42-4.27) compared to HHIE-S.
• Specificities were comparable between the two tools (Audioscope: 0.80-0.91; HHIE-S: 0.75-0.93).
• A significant majority of patients preferred Audioscope screening (60%) over HHIE-S (13%).

Conclusions:

• The Audioscope is a more effective and preferred screening tool for hearing loss in primary care settings for older adults.
• Its higher sensitivity and positive likelihood ratios suggest better identification of individuals with hearing impairment.
• The findings support the use of Audioscope as a primary screening method in geriatric audiology.
