# Evaluation of a digital health decision intervention to support management decision-making for adults with hearing loss: protocol for the HearChoice randomised controlled trial

## TL;DR

This study tests an online tool called HearChoice to help adults with hearing loss make informed decisions about their healthcare options.

## Contribution

The HearChoice intervention is a novel digital decision support tool co-developed to address barriers in hearing healthcare decision-making.

## Key findings

- The trial will assess HearChoice's effectiveness in reducing decisional conflict and improving hearing-related quality of life.
- Outcomes will be compared against an active control group using a Hearing Option Grid.
- Feasibility and health economics of the intervention will also be evaluated.

## Abstract

Hearing loss is highly prevalent and impacts many aspects of a person’s life, including communication, social engagement, employment, general health and well-being. Yet, many people do not access hearing healthcare and are unaware of the range of hearing healthcare options available. Barriers to hearing healthcare include poor understanding of hearing loss and its impact; poor knowledge of help-seeking for hearing healthcare options; minimal support to help decide which option is best; and stigma related to hearing loss. These barriers lead to many people not receiving the hearing healthcare they need. Guided by theories of behaviour change and implementation science, HearChoice, an online tailored decision support intervention, has been co-developed to empower adults with hearing difficulties by offering them choice and control over their own hearing healthcare. HearChoice aims to facilitate informed decisions, accessibility and uptake of hearing healthcare, including a wide range of interventions, for adults with hearing difficulties. The objectives of the trial are to evaluate the effectiveness, health economics and feasibility of HearChoice.

This online randomised controlled trial will recruit participants with hearing difficulties across Australia, with an anticipated sample size of 640. Participants will be randomised to either HearChoice (treatment) or an Australia-specific Hearing Option Grid (active control), both delivered online. Outcomes will be assessed at baseline when the interventions will be offered, at 7 days post-intervention (primary endpoint) and at 3 months post-intervention. An email reminder will be sent at 1-month post-intervention. The primary outcome is decisional conflict. Secondary outcomes include measures of readiness and self-efficacy to take action, hearing-related quality of life and empowerment, assessment of the value and impact of HearChoice, work performance and health, and feasibility measures. Primary analysis will compare outcomes between HearChoice and the active control at the primary endpoint.

The study was approved by the Curtin University Human Ethics Committee (HRE2023-0024). All participants will provide written informed consent prior to participation. A broad dissemination plan of the study findings includes peer-reviewed publications, scientific conference presentations, articles and presentations for the wider community and public written in lay and accessible language, and social media.
