Audiologist-Led Tinnitus Care Outcomes in Singapore

Audiologist-led tinnitus management at a public hospital in Singapore led to a significant reduction in distress for 93% of patients who returned for follow-up care. A retrospective study of 201 patients found their average Tinnitus Handicap Inventory (THI) score dropped from 46.9 to 24.3 within three months of starting treatment. This improvement represents a large treatment effect, offering strong support for structured audiological care in an Asian healthcare setting.

## A Closer Look at the Study’s Methodology

Researchers Gary Jek Chong Lee, Jasmine Jek Peng Liew, and Andrew K. Teng conducted a retrospective analysis of patient records from a specialist tinnitus clinic at a Singapore public hospital. They extracted data for all patients seen between 2016 and 2019. The primary measure of success was a change in the Tinnitus Handicap Inventory (THI) score, a validated questionnaire that quantifies the impact of tinnitus on daily life.

Patients completed the THI before starting treatment and again approximately three months later. The study included 201 adults aged 18 to 86 years. This method allowed the team to assess real-world outcomes of the clinic’s standard management protocol, which typically involves detailed assessment, counseling, sound therapy, and hearing aid fitting when appropriate.

## Significant Reductions in Tinnitus Distress and Handicap

The results demonstrate clear benefits from the audiological intervention. For the cohort that returned for their follow-up assessment, an overwhelming 93% recorded a lower THI score after three months of management. The statistical analysis confirmed the drop in average scores—from 46.9 to 24.3—was not due to chance.

A score of 46.9 falls into the “moderate handicap” category, while 24.3 is classified as “mild handicap.” The calculated effect size of 1.16 is considered large in clinical research, indicating the treatment had a substantial practical impact on patients’ lives. Furthermore, the research found that 81% of patients who started with a moderate, severe, or catastrophic THI grade improved by at least one full severity level. This suggests the clinic’s approach is particularly effective for those experiencing higher levels of tinnitus-related distress.

## Implications for Patients and Healthcare Systems

This Singapore-based study adds to a growing body of international evidence that audiologists are well-positioned to provide effective first-line management for troublesome tinnitus. The findings argue for the integration of such specialist services within broader hearing healthcare pathways.

A key practical implication is the role of other health professionals. The authors note that general practitioners and otolaryngologists (ENT doctors) are often the first point of contact for someone distressed by tinnitus. These providers can offer crucial early reassurance, rule out any underlying medical conditions, and make timely referrals to audiologist-led clinics. This early direction to appropriate care can prevent the negative cycle of anxiety and isolation that often worsens tinnitus perception.

The study also highlights a common challenge in real-world clinical research: not all patients return for follow-up. While the outcomes for those who did return were positive, the experience of those lost to follow-up is unknown. This points to a need for continued work on patient engagement and support throughout the management process.

## Future Directions for Tinnitus Care and Research

Lee, Liew, and Teng acknowledge that while their results are encouraging, controlled studies are needed to confirm the specific effectiveness of the audiologist-delivered components. Comparing this structured management to a control group would help isolate the active ingredients of the care provided.

The success in Singapore suggests similar models could be beneficial in other Asian healthcare settings, where cultural perceptions of tinnitus and help-seeking behaviors may differ from Western populations. Furthermore, as awareness grows, there is potential to explore connections with managing other sound tolerance conditions often seen in tinnitus clinics. For instance, the structured counseling and therapeutic sound approaches used in tinnitus management may offer insights for treating misophonia, which involves strong emotional reactions to specific sounds.

The research reinforces that tinnitus is a manageable condition for most people. It shifts the focus from a search for a singular “cure” to the implementation of proven rehabilitative strategies that reduce distress and improve quality of life.
