This study sought to validate the applicability of the mandarin Tinnitus Evaluation Questionnaire (TEQ), a brief score method administered by clinicians to quantify the tinnitus severity. A descriptive observational questionnaire study in regard to psychometric properties and practicability was conducted with a total of 414 primary tinnitus outpatients, in which 173 of 414 patients completed the follow-up after receiving an intervention based on the tinnitus educational counseling and the life-style adjustment guidance. For quantifying the tinnitus severity, the TEQ and other 2 self-report questionnaires, Tinnitus Handicap Inventory and visual analog scale, were administered on patients’ first-visit and follow-up. With the psychometric analysis, we evaluated the performance of TEQ in tinnitus management, including distinguishing patients with varying severity and detecting the treatment-related outcome. At the first visit, the TEQ showed an excellent inter-rater reliability (Pearson correlation, 0.97, P < .01), a good internal consistency reliability (Cronbach's α, 0.79), and an acceptable convergent validity (Pearson correlation, 0.78 with the Tinnitus Handicap Inventory; 0.62 with a single-question visual analog scale, P < .01). In detecting the treatment-related change, a large effect size of TEQ verified a sensitive responsiveness. After estimating the test-error, a 2-point reduction (2/21) of the TEQ was recommend to be considered a reference outcome indicator for the effective intervention. Even though the TEQ is scored by clinician, it can reflect the clinical features of tinnitus patient. Flexible and simple assessing process makes it a practical tool for patient intake, intervention selection, and outcome measurement.

BackgroundIdiopathic sudden sensorineural hearing loss (ISSNHL) is a major cause of deafness. Despite the advances in systemic therapy, some cases of ISSNHL are untreated, because the exact ISSNHL aetiology is unclear. Traditional Chinese medicine (TCM) has been used to treat diseases for thousands of years and is popular and widely practiced in Asia. TCM includes guidance on a healthy lifestyle. In recent decades, the relationship between lifestyle and disease has been emphasised; an unhealthy lifestyle may lead to illnesses. Thus, this study aims to compare the efficacy of lifestyle modification based on TCM with the usual consultation of ISSNHL after failure of a 2-week systemic therapy to provide a scientific basis for clinical decisions.MethodsThis study is a clinical randomised trial that involves 56 patients diagnosed with ISSNHL but who have had incomplete recovery after initial management (at least 2 weeks of routine Western medical treatment). The study is performed in accordance with the sudden hearing loss clinical guideline of the American Academy of Otolaryngology–Head and Neck Surgery, published in 2012. Participants are randomly distributed into two groups: the healthy lifestyle modification group based on TCM and the control group (1:1 ratio). Patient follow-up lasts for 3 months. The primary outcome measure is the effective rate of hearing improvement, which is defined as the proportion of patients with at least 15 dB of improvement in the average thresholds of hearing loss frequency. The secondary outcome measures are improvements in word recognition score, Tinnitus Handicap Inventory and visual analogue scale for ear blockage and dizziness. Assessments are made at baseline and after lifestyle modification for 1 and 3 months.DiscussionThe efficacy of healthy lifestyle modification based on a TCM programme for patients with ISSNHL with incomplete recovery after failure of initial systemic therapy is determined in this trial. Positive results will provide clinical evidence on the effects of a TCM-based healthy lifestyle, which could be recommended as salvage therapy for patients with ISSNHL.Trial registrationChinese Clinical Trial Registry, ChiCTR-INR-17011459.
