The purpose of hearing aid prescription is to improve the patient’s functioning and quality of life. This post has some resources for assessing the effect of hearing aid prescription on those metrics.
“A variety of tools exists to assess communication needs and function, as well as
assisting in evaluating patient expectations of hearing aid use. These include, but are not limited to, the Client Oriented Scale of Improvement (COSI) (1),
Abbreviated Profile of Hearing Aid Benefit (APHAB) (2), Hearing Handicap Inventory for the Elderly (HHIE) (3), and Expected Consequences of Hearing Aid Ownership (ECHO) (4). Lifestyle questionnaires are also available from specific hearing aid manufacturers and network providers. Most of these tools can be administered quickly so that goals can be outlined in a pragmatic and timely fashion. Use of these assessment tools can assist in the selection of particular amplification features such as directional microphones, direct audio input, environmental noise management, frequency modulated (FM) systems, and so on.”
“Following the fitting, these same measurement tools can be used to help quantify the patient’s functional benefits/satisfaction with amplification. Following the administration of the above-mentioned tools, a list of realistic patient goals can be developed. It is important to include both “cognitive” and “affective” goals. For example, a “cognitive goal” may be “improved conversation with a spouse in a quiet environment” or “improved communication with unfamiliar speakers on the telephone without removal of thehearing aid.” An “affective goal” could be “feeling less embarrassment or distress during
communication.” These goals can be evaluated as to the amount of change with the use of
amplification. The statements or questions in the HHIE, COSI, and ECHO contain both cognitive and affective characteristics.”
“The importance of specifying patient goals continues to be a challenge with the
introduction of new hearing aid features. Patient demands and expectations increase due to the commercial promotion of certain hearing aid features such as adaptive directional microphones, environmental noise reduction, and automatic telecoils.”
