Development and Validation of NIRS-Based Sinusitis Screening
DESCRIPTION (provided by applicant): In the U.S., chronic sinusits is associated with over 40 million visits to physicians and health care providers each year. Sinusitis is diagnosed based on clinical history which is difficult to correctly ascertain, andhence misdiagnosis leads to both over-treatment (i.e. antibiotics) and under-treatment (i.e. misdiagnosis as allergies or migraine). Praxis Biosciences, LLC aims to develop and deliver a very low-cost optical imaging tool for quick and simple assessment ofsinusitis suitable for use by both primary care doctors and physician extenders. In this proposal, we will first improve on the design of a novel validated prototype developed at the Beckman Laser Institute at UC Irvine by optimizing device form factor, robustness, and optical design. Our device is based upon the principles of near-infrared (NIR) trans-illumination but exploits the unique near infrared optical properties of living tissue to generate substantially greater signal yield. In the second phase of the fast-track, we will validate its efficacy of this market-ready optimized device via a clinical study with Ear, Nose and Throat (ENT) specialists and primary care physicians. The proposed low-cost optical imaging tool will be able to provide means tobetter identify patients with acute sinusitis and then monitor the response to therapy in primary care settings. Ultimately, our device will help reduce the health-care costs related by optimizing and streamlining diagnosis and treatment. PUBLIC HEALTH RELEVANCE: In the US, chronic sinusitis affects approximately 32 million persons each year and accounts for 11.6 million visits to physicians' offices. Current diagnostic methods in primary care settings suffer from relatively low sensitivity and leadsto over 40% of false negative findings. The proposed product based on NIRS imaging method will enable primary physicians to make simple and quick diagnosis of sinusitis.
