Abstract
BackgroundLeveraging the data management resources of the Canadian Primary Care Sentinel Surveillance Network (CPCSSN) is a viable approach for describing the prevalence of allergic disease documented in primary care settings.MethodsThe dataset used for this study was inclusive of data from EMR initiation up to Dec 31st 2018. The sample included 1235 primary care providers representing 1,556,472 patients across Canada.ResultsIn total, there were 536,005 patients with a documented allergy that fit into one of the 10 suggested categories. The allergy table includes 718,032 distinct entries representing 564,242 unique patients, which is 36.3% of the patients within the CPCSSN repository. The most common allergies recorded were drug allergy (39.0%), beta-lactam allergy (14.4%), environmental allergy (11.0%), and food allergy (8.0%). Anticipated upcoming studies include physician-documented drug allergy with a focus on beta-lactam allergy, as well as stinging insect allergy, among others. To our knowledge, these will also be the first such prevalence studies of primary care physician-documented allergic disease done in Canada.InterpretationThe CPCSSN dataset represents electronic medical records from 1.5 million patients across Canada including documentation of allergic diseases. This dataset provides a national representative population to describe and characterize Canadian patients with common allergic conditions. This robust dataset provides the opportunity for health surveillance, and in particular data to explore the impact of allergic disease on primary care practice.Trial registrationNot applicable.
Highlights
Disease prevalence rates can estimate the burden of disease, highlight research priorities, direct guidelines and medical policy, inform healthcare economic models, and provide a baseline for interventional research [1]
Primary care physician documentation present an opportunity to estimate the prevalence of allergic conditions.”

Summary
Disease prevalence rates can estimate the burden of disease, highlight research priorities, direct guidelines and medical policy, inform healthcare economic models, and provide a baseline for interventional research (by providing baseline risk in a population) [1]. *Correspondence: elissa.abrams@gmail.com 4 Department of Pediatrics, Section of Allergy and Clinical Immunology, University of Manitoba, FE125‐685 William Avenue, Winnipeg, MB R3E 0Z2, Canada Full list of author information is available at the end of the article means including self-report, or medical record data. Prevalence of common allergic conditions can vary significantly between studies, with self-reported allergy often higher than diagnosed allergy [2].
