Screening for Psychiatric Disorders in Chronic Rhinosinusitis Patients Waiting for Surgery: A Prospective Cross-Sectional Study.

Objective: To assess the prevalence of depression, anxiety, insomnia and somatic symptom disorder (SSD) in chronic rhinosinusitis (CRS) patients who were waiting for surgery and to predict these psychiatric disorders using the 22-item Sinonasal Outcome Test (SNOT-22).

Design: A prospective cross-sectional study.

Setting: The rhinology ward at our institution, a tertiary hospital.

Participants: Adult patients (> 18 years) diagnosed with CRS who were admitted to the rhinology ward for endoscopic sinus surgery and were able to understand and complete the study questionnaires.

Main Outcome Measures: Patient Health Questionnaire-9 (PHQ-9), Generalised Anxiety Disorder-7 (GAD-7), Insomnia Severity Index (ISI), Patient Health Questionnaire-15 (PHQ-15) and SNOT-22.

Results: Of the 159 participants recruited, 58 were at risk of depression (defined by PHQ-9 > 4, while 25 with PHQ-9 > 9), 49 were at risk of anxiety (defined by GAD-7 > 4, while 25 with GAD-7 > 9), 81 were at risk of insomnia (defined by ISI > 7, while 51 with ISI > 14) and 69 were at risk of SSD (defined by PHQ-15 > 4, while 24 with PHQ-15 > 9). The SNOT-22 score was closely correlated with the scores of psychometric tests and was an independent predictor of these psychiatric disorders. Patients with a high SNOT-22 score (> 30) are likely to be affected by comorbid psychiatric disorders and should be further evaluated by otolaryngologists.

Conclusion: Depression, anxiety, insomnia and SSD are prevalent in CRS patients. Otolaryngologists should have a low threshold to ask the patient about psychiatric symptoms, especially for patients with an SNOT-22 score > 30.
