Study summary

Age-related hearing loss is highly prevalent and hearing health care is underutilized. The primary objective of the proposed randomized controlled trial is to investigate the efficacy of a community health worker (CHW)-delivered hearing loss intervention program. A preceding pilot study demonstrated preliminary effectiveness of the intervention program in reducing self-reported hearing handicap, and highlighted its acceptability among the target demographic. The proposed trial will now expand upon lessons learned through previous pilot studies and expand to other affordable residences for low-to-moderate income older adults in Baltimore. Primary outcome measurements will investigate intervention effects on hearing handicap, with secondary measurements investigating effects on domains such as social isolation and quality of life. This trial is a first-in-kind investigation of a novel community-based intervention that addresses hearing loss in a vulnerable, urban population.

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What researchers measure

Primary outcomes

  1. Change From Baseline in Hearing Handicap Inventory for the Elderly (HHIE-S)

    Measure was collected through a one-on-one interview with a trained data collector. Higher scores indicate increased hearing handicap. Scoring: 0-8 suggests no hearing handicap 10-24 suggests mild-moderate hearing handicap 26-40 suggests significant hearing handicap Change from baseline is reported. An increase in the score from baseline (a positive number) indicates a worsening in hearing handicap.

This 5 question survey measures listening self efficacy on a 0-10 scale in different situations such as being able to understand a conversation in a quiet room to a crowded restaurant. Participants answer with a higher number the more confident they are in the presented situation. Maximum possible score is 50. Change from baseline score is reported. An increase in the score from baseline (a positive number) indicates a higher self-efficacy.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Apr 2018 to primary completion in Jun 2020, 25 months.

Results were first posted in Oct 2021, 1 year 3 months after primary completion.

Of 390 non-industry interventional studies with no phase under Communication, half reached primary completion within 18 months of starting (the median), counting those still running; a quarter within 6 and three quarters within 36. This study's 25 months is above that.

Counting every sponsor, half of 394 studies reached it within 18 months; a quarter within 6 and three quarters within 36.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Oct 4, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
