Tinnitus Management Outcomes in Singapore Public Health

93% of patients showed a measurable reduction in tinnitus-related distress three months after receiving structured management from an audiologist. This finding comes from a retrospective study at a public hospital in Singapore, one of the first to report outcomes for an audiologist-led tinnitus service in Asia. The research, led by Gary Jek Chong Lee, Jasmine Jek Peng Liew, and Andrew K. Teng, provides strong preliminary evidence for the effectiveness of this clinical model.

Evaluating a Specialized Tinnitus Clinic Model

The study aimed to evaluate the real-world outcomes of an audiologist-delivered tinnitus management service at Singapore General Hospital. With tinnitus known to adversely affect daily functioning for many, and specialized audiologists increasingly providing this rehabilitation, the researchers sought to measure its impact. They conducted a retrospective analysis, extracting data from the hospital’s electronic medical records for patients seen between 2016 and 2019.

The core method was a comparison of standardized self-report scores. All patients referred to the audiologist-led clinic completed the Tinnitus Handicap Inventory (THI) before starting treatment. The THI quantifies the perceived impact of tinnitus on life, with scores categorized as slight (0-16), mild (18-36), moderate (38-56), severe (58-76), or catastrophic (78-100). Patients then received individualized management from audiologists, which could include counseling, sound therapy fitting and verification, and hearing aid provision if needed. Their THI scores were reassessed approximately three months after treatment began.

Significant Reductions in Tinnitus Handicap

The analysis included 201 patients aged 18 to 86 years. The most compelling result was the high rate of improvement. Among patients who returned for their follow-up appointment, 93% showed a decrease in their THI score.

The quantitative changes were substantial. The mean THI score fell from 46.9 before treatment to 24.3 after three months. This drop represents a shift from the “moderate handicap” category to the “mild handicap” category on average. The statistical effect size was calculated at 1.16, which is considered large in clinical research.

The clinical significance was also clear. For patients whose baseline THI score indicated a moderate handicap or worse, 81% improved by at least one full severity grade (e.g., from severe to moderate). This indicates that the management provided meaningful, perceptible relief for a large majority of those more significantly affected.

Implications for Hearing Healthcare Pathways

The authors conclude that their findings are consistent with a potential role for structured, audiologist-led tinnitus services in Asian healthcare settings. They note that controlled studies are needed to confirm treatment effectiveness, but the retrospective data is highly promising.

This has direct implications for clinical practice. The study highlights the importance of healthcare providers recognizing tinnitus-related distress. General practitioners and otolaryngologists (ENTs) are often the first point of contact. They can offer early reassurance, validate the patient’s experience, and make timely referrals to specialized audiological care. This pathway can prevent the distress and functional impact of tinnitus from worsening.

The success of this model also aligns with a growing focus on multidisciplinary and accessible care for hearing disorders. Just as research explores biomarkers for tinnitus for better diagnosis, and digital therapeutics for wider access, establishing effective clinical protocols within public health systems is vital. For patients with overlapping conditions like hyperacusis or misophonia, which often co-occur with tinnitus, an audiologist can be a central figure in management, potentially integrating approaches like cognitive behavioral therapy.

A Model for Structured Audiological Care

This research, published in OHBM (DOI: 10.3390/ohbm7020030), provides a template for evaluating and implementing tinnitus services. It demonstrates that audiologists, with their expertise in hearing function and sound-based therapies, can deliver care that leads to statistically and clinically significant improvements for patients.

The high rate of improvement—93%—suggests that a standardized, patient-centered approach managed by a trained professional can help most people reduce the burden of their tinnitus. It argues for the further integration of such services into standard hearing healthcare pathways, ensuring that people experiencing tinnitus distress have a clear and effective route to support.
