In the United States, chronic rhinosinusitis is a widespread chronic illness that is diagnosed in patients of nearly all ages. The project was designed to develop and test an algorithm for identifying chronic/recurrent acute sinusitis.


The goal of the project is to better understand both the diagnosis and management of chronic rhinosinusitis by primary care physicians at NorthShore. Given the prevalence of this condition, and that primary care physicians are typically the first point of entry into medical care for patients, this project can enhance the accuracy and rapidity of diagnosis, and resolution/management to provide better care for patients who suffer repeated and lengthy episodes of sinusitis.


A total of 2,869 patient cases were analyzed through the use of the Enterprise Data Warehouse (EDW).
