Single-use device endoscopy for the diagnosis of acute bacterial rhinosinusitis in primary care: A pilot and feasibility study.

Objective: Antibiotics are largely overprescribed for acute rhinosinusitis in primary care, mainly due to the lack of diagnostic tests to confirm or rule out bacterial infection. The study objective was to assess the on-site applicability and safety of the newly developed JGG endoscope for the diagnosis of acute bacterial rhinosinusitis in primary care.

Design: Five Swiss primary care centres and one university-affiliated ENT unit participated in this single-arm pilot study.
