What is the recommended evaluation and management for a patient with hearing loss?

Care for Hard of Hearing Patients

All patients aged 50 years and older should be screened for hearing loss at every healthcare encounter, and if screening is positive, they must receive an audiogram, ear examination, and be offered appropriately fitted amplification. 1

Screening Approach

Screen all adults ≥50 years old at healthcare encounters using:

• Audioscope (hand-held combination otoscope/audiometer)
• Hearing Handicap Inventory for the Elderly-Screening version (self-administered questionnaire)
• Single-question screens asking about hearing difficulty 1, 2

The 2024 AAO-HNS guideline emphasizes that despite age being the strongest predictor of hearing loss, only 17% of physicians currently conduct screening, leading to underdiagnosis and increased risks of frailty, depression, cognitive decline, and higher healthcare costs 1.

Initial Evaluation When Screening Suggests Hearing Loss

1. Ear Examination (KAS 2)

Examine the ear canal and tympanic membrane with otoscopy for:

• Cerumen impaction (present in up to 30% of elderly patients with hearing loss - potentially curative if treated) 3, 2
• Infection
• Exostoses
• Other canal/tympanic membrane abnormalities 1

2. Identify Sociodemographic Factors (KAS 3)

Assess factors influencing access to hearing healthcare:

• Financial barriers
• Transportation limitations
• Cultural preferences
• Health literacy 1

3. Obtain Audiogram (KAS 4 - Strong Recommendation)

This is a strong recommendation - obtain or refer for formal audiometry. Pure tone audiometry is essential for:

• Determining type of hearing loss (sensorineural, conductive, or mixed)
• Quantifying severity
• Identifying asymmetry
• Assessing word recognition 1, 3

Red Flags Requiring Urgent/Specialty Referral

Immediate Otolaryngology Referral:

• Sudden sensorineural hearing loss (≥30 dB loss within 72 hours) - requires prompt evaluation 3, 4
• Significant asymmetric hearing loss (suggests acoustic neuroma or other pathology) 1, 3
• Conductive or mixed hearing loss (may require surgical intervention) 1
• Poor word recognition disproportionate to pure tone thresholds 1

Imaging Indications:

Order CT or MRI for:

• Asymmetrical hearing loss
• Sudden sensorineural hearing loss
• Suspected ossicular chain damage
• Progressive hearing loss
• Auditory neuropathy 5, 3

Management Algorithm

For Age-Related Sensorineural Hearing Loss (Most Common):

1. Patient Education and Counseling (KAS 6) Educate patients and family/care partners about hearing loss impact on:

• Communication abilities
• Safety (missing alarms, traffic sounds)
• Cognitive function
• Quality of life
• Social isolation and depression risk 1

2. Communication Strategies and Assistive Devices (KAS 7) Counsel on:

• Face-to-face communication techniques
• Reducing background noise
• Assistive listening devices (amplified telephones, TV listening systems, alerting devices)
• Captioning services 1

3. Amplification (KAS 8 - Strong Recommendation) Offer or refer for appropriately fitted hearing aids. This is a strong recommendation based on randomized trials demonstrating improved outcomes including:

• Reduced disability
• Improved quality of life
• Decreased cognitive impairment
• Reduced psychosocial distress 1, 2, 6

Common Pitfall:

Nonadherence to hearing aid use is high 2. Address this by:

• Setting realistic expectations
• Ensuring proper fitting by audiologist
• Providing adequate training
• Scheduling follow-up to troubleshoot issues

4. Cochlear Implant Evaluation (KAS 9 - Strong Recommendation) Refer for cochlear implant candidacy evaluation when patients have appropriately fitted amplification but persistent hearing difficulty with poor speech understanding. Many patients who could benefit from cochlear implants are not referred - don't miss this opportunity 1, 3.

For Conductive Hearing Loss:

• Treat cerumen impaction with irrigation or curettage (potentially curative) 3
• Refer to otolaryngology for evaluation of middle ear pathology, ossicular chain problems, or surgical candidacy 1, 3

Follow-Up and Monitoring

Assess Treatment Outcomes (KAS 10):

Within 1 year or at subsequent encounter, evaluate:

• Whether communication goals have been met
• Improvement in hearing-related quality of life
• Hearing aid adherence and satisfaction 1

Ongoing Monitoring (KAS 11):

• Reassess hearing at least every 3 years in patients with known hearing loss
• More frequent assessment if patient reports hearing changes
• Consider periodic genetics follow-up every 3 years if genetic evaluation was negative, as syndromic features may emerge over time 5

Special Considerations

Eliminate Ototoxic Medications:

Review and reduce/eliminate when possible:

• Aminoglycosides
• Loop diuretics
• Platinum-based chemotherapy
• High-dose aspirin 3

Multidisciplinary Referral:

For complex cases, refer to multidisciplinary hearing centers including:

• Otolaryngologists
• Audiologists
• Clinical geneticists (especially for unexplained, early-onset, or familial hearing loss)
• Speech-language pathologists
• Aural rehabilitation specialists 5, 6

The key to optimal outcomes is early identification through systematic screening, prompt audiometric evaluation, and aggressive treatment with appropriately fitted amplification, with cochlear implant evaluation for those with persistent difficulty despite hearing aids. 1
