Hearing Loss clinical trials at UC Health
2 in progress, 1 open to new patients
open to eligible people ages 60 years and up
Hearing loss screening rates in for older persons in primary care clinics are very low even though hearing loss is relatively common for older persons. When diagnosed with hearing loss older persons are often reluctant to follow through. This study involves a prospective controlled trial comparing the effectiveness of three primary care based protocols for older adults ≥ 60 who screen positive for possible hearing loss in promoting subsequent access to and use of hearing health care services. The protocols will compare: 1) screening only (standard care control); 2) screening plus an illustrated educational brochure; and 3) screening plus an in-person educational intervention and an illustrated educational brochure. Screening will be done by primary care personnel. Participants will be tracked for 8 months to assess outcomes.

Fifty adults with mild to moderately severe sensorineural hearing loss will be fit with hearing amplification using two adjustment techniques. For the "audiologist fitting" technique, a licensed audiologist will adjust the hearing device using the standard of care procedures which include adjustment and verification of output to match prescribed targets (NAL-NL2) and subsequent fine tuning to optimize adjustments based on participant feedback. The second technique is "user-adjustment" of the device consisting of adjustment to overall level, high-frequency boost, and low-frequency cut by the participant while listening to speech. A cross-over design will be used in which half the participants are initially fit using the audiologist technique and the other half are initially fit using the user self-adjustment technique. Following a seven-day field trial, participants will return to the lab and the aids will be reset use the other technique. Participants will be blinded to the condition. During each seven-day field trial, users will have access to a volume control, Following the end of the two trials, participants will return to the lab for outcome assessment.
