“…≥18 years) being cared for by 444 primary care providers participating in the Canadian Primary Care Sentinel Surveillance Network (CPCSSN), an overall hypertension prevalence of 22.8% in 2012 was reported [52]. Seventy-eight percent of patients with hypertension were controlled to target, higher than in the present analysis.…”

“…Since 2010, clinical medicine and public health have benefited from a rapid surge of research on the burden and management of chronic diseases using electronic health records (EHRs) 1–12. EHRs are appealing because they can offer large sample sizes, timely information, and clinical data beyond that obtained from health surveys or administrative data 9,13,14.…”

Introduction:Electronic health records (EHRs) can potentially extend chronic disease surveillance, but few EHR-based initiatives tracking population-based metrics have been validated for accuracy. We designed a new EHR-based population health surveillance system for New York City (NYC) known as NYC Macroscope. This report is the third in a 3-part series describing the development and validation of that system. The first report describes governance and technical infrastructure underlying the NYC Macroscope. The second report describes validation methods and presents validation results for estimates of obesity, smoking, depression and influenza vaccination. In this third paper we present validation findings for metabolic indicators (hypertension, hyperlipidemia, diabetes).Methods:We compared EHR-based estimates to those from a gold standard surveillance source - the 2013–2014 NYC Health and Nutrition Examination Survey (NYC HANES) - overall and stratified by sex and age group, using the two one-sided test of equivalence and other validation criteria.Results:EHR-based hypertension prevalence estimates were highly concordant with NYC HANES estimates. Diabetes prevalence estimates were highly concordant when measuring diagnosed diabetes but less so when incorporating laboratory results. Hypercholesterolemia prevalence estimates were less concordant overall. Measures to assess treatment and control of the 3 metabolic conditions performed poorly.Discussion:While indicator performance was variable, findings here confirm that a carefully constructed EHR-based surveillance system can generate prevalence estimates comparable to those from gold-standard examination surveys for certain metabolic conditions such as hypertension and diabetes.Conclusions:Standardized EHR metrics have potential utility for surveillance at lower annual costs than surveys, especially as representativeness of contributing clinical practices to EHR-based surveillance systems increases.

“…At that time, the network included data from 444 sentinel physicians and nurse practitioners providing data on more than 440 000 patients from their practices in 7 provinces across Canada. Data from this period have been used consistently in a series of studies describing the prevalence and management of the 8 CPCSSN "index conditions" in primary care, [12][13][14][15][16] of which this study is the latest.…”
