Screening for Eustachian Tube Dysfunction in Clinical Practice Using the Eustachian Tube Dysfunction Questionnaire-7.
OBJECTIVES/HYPOTHESIS: To evaluate the ability of the Eustachian Tube Dysfunction Questionnaire-7 (ETDQ-7) to discriminate between patients with Eustachian tube dysfunction (ETD) and Non-ETD diagnoses, and identify symptom information to improve ability to discriminate these groups. STUDY DESIGN: Cohort study. METHODS: Pilot retrospective study with consecutive adult patients presenting to otology clinics and one general otolaryngology clinic in an academic health system. Patients were administered ETDQ-7 with eight additional symptom items. Electronic health records were reviewed for demographic and diagnostic information. Patients were grouped into diagnosis categories: 1) True ETD, 2) experiencing ear fullness (EF) not due to ETD, and 3) Control patients without ETD-related disorders or EF. ETDQ-7 and symptom item scores were compared by the diagnosis group. Receiver-operative characteristics curves and area under the curve (AUC) were generated for each ETD diagnosis group based on ETDQ-7 and symptom scores. RESULTS: Of the 108 patients included in this study 74 (68.5%) were diagnosed with ETD. Patients with ETD had higher (indicating worse symptom burden) overall ETDQ-7 scores than Control group (Median [Q1, Q3] 3.0, [1.7, 4.1]; versus 1.5 [1.0, 3.4] P = .008). There was no statistically significant difference between overall ETDQ-7 scores for ETD and Non-ETD EF patients (P = .389). The AUC for the ETDQ-7 in discriminating ETD from other conditions that cause EF was 0.569; the addition of 8 symptom questions to the ETDQ-7 improved AUC to 0.801. CONCLUSION: Additional patient-reported symptom information may improve the ability to discriminate ETD from other similarly presenting diagnoses when using ETDQ-7.
