Perceived hearing aid benefit in relation to perceived needs

Area of Science:

• Audiology
• Hearing Healthcare
• Medical Devices

Background:

• Assessing patient needs and expectations is crucial for managing outcomes with hearing aid fittings.
• Existing tools may not fully capture the nuances of perceived communication challenges.
• Understanding the gap between expectation and benefit is key to patient satisfaction.

Purpose of the Study:

• To introduce and validate the Hearing Aid Needs Assessment (HANA) scale.
• To investigate the relationship between pre-fitting perceived communication needs and post-fitting hearing aid benefit.
• To determine if patient expectations predict actual hearing aid performance.

Main Methods:

• Development and administration of the HANA scale to 82 patients before hearing aid consultation.
• Follow-up assessment using the Hearing Aid Performance Inventory for a subgroup of 42 patients after 2-3 months of hearing aid use.
• Analysis of the correlation between HANA scores and hearing aid benefit.

Main Results:

• Patients seeking hearing aids generally expect greater benefits than they typically experience.
• This expectation-benefit gap is more pronounced in difficult listening environments, such as speech in noise or with absent visual cues.
• Perceived needs and expectations, as measured by HANA, were largely unreliable predictors of the actual hearing aid benefit achieved.

Conclusions:

• The Hearing Aid Needs Assessment (HANA) provides insights into patient expectations for hearing aid users.
• A significant discrepancy exists between the anticipated benefits of hearing aids and the realized outcomes.
• Current measures of perceived need and expectation have limited ability to forecast the success of hearing aid interventions.
