Chronic rhinosinusitis: epidemiology and cost

Abstract

Chronic rhinosinusitis (CRS) is one of the most common chronic diseases and is associated with a high socioeconomic burden from direct and indirect costs. Its estimated prevalence ranges widely, from 2 to 16%. It is more common in female subjects, aged 18-64 years, and in southern and midwestern regions of the United States. CRS is more prevalent in patients with comorbid diseases such as asthma, chronic obstructive pulmonary disease, and environmental allergies. Few studies examine patient ethnicity, socioeconomic status, geographic location, and cultural factors in CRS populations. This article provides an overview of the epidemiology, racial variations, and economic burden of CRS.
