Purpose: The specific aims of this paper are to (1) develop and operationalize an electronic health record (EHR) data quality framework, (2) apply the dimensions of the framework to the phenotype and treatment pathways of ductal carcinoma in situ (DCIS) using Research Program data, and (3) propose and apply a checklist to evaluate the application of the framework.

Methods: We developed a framework of five data quality dimensions (DQD; completeness, concordance, conformance, plausibility, and temporality). Participants signed a consent and Health Insurance Portability and Accountability Act authorization to share EHR data and responded to demographic questions in the Basics questionnaire.

Background: Self-measured blood pressure (SMBP) is an effective strategy for managing and controlling hypertension. However, uncertainty regarding patients' ability to accurately measure their blood pressure (BP) contributes to treatment inertia. Therefore, we compared BP measurements with the Omron HEM-9210T device obtained by nurses and community-dwelling adults after training.

Background: The National Health and Nutrition Examination Survey data indicate that the proportion of US adults with hypertension that had controlled blood pressure (BP) declined from 2013 to 2014 through 2017 to 2018. We analyzed data from National Health and Nutrition Examination Survey 2009 to 2012, 2013 to 2016, and 2017 to 2020 to confirm this finding.

Methods: Hypertension was defined as systolic BP ≥140 mm Hg or diastolic BP ≥90 mm Hg or antihypertensive medication use.

Background: To compare prevalence of hypertension and stage II hypertension assessed by 2 blood pressure (BP) observation protocols.

Methods: Participants aged 18 years and older (n = 4,689) in the National Health and Nutrition Examination Survey (NHANES 2017-2018) had their BP measured following 2 protocols: the legacy auscultation protocol (AP) and oscillometric protocol (OP). The order of protocols was randomly assigned.

Objectives Blood pressure (BP) is traditionally measured using a mercury sphygmomanometer. Given environmental concerns about mercury, clinical and survey settingsare moving to automated devices with an oscillometric protocol to obtain BP. This report compares BP measurement using the mercury and oscillometric protocols.

Background And Objectives: In March 2020, the coronavirus disease 2019 (COVID-19) pandemic halted National Health and Nutrition Examination Survey (NHANES) field operations. As data collected in the partial 2019-2020 cycle (herein referred to as 2019-March 2020) are not nationally representative, they were combined with previously released 2017-2018 data to produce nationally representative estimates. This report explains the creation of the 2017-March 2020 prepandemic data files, provides recommendations for and limitations of the files' use, and presents prevalence estimates for selected health outcomes based on the files.

Background: To examine the associations between urbanization and hypertension, stage II hypertension, and hypertension control.

Methods: Data on 16,360 US adults aged 18 years or older from the 2013-2018 National Health and Nutrition Examination Survey (NHANES) were used to estimate the prevalence of hypertension (blood pressure (BP) ≥130/80 mm Hg or use of medication for hypertension), stage II hypertension (BP ≥140/90 mm Hg), and hypertension control (BP <130/80 mm Hg among hypertensives) by urbanization, classified by levels of metropolitan statistical areas as large MSAs (population ≥1,000,000), medium to small MSAs (population 50,000-999,999), and non-MSAs (population <50,000).

Results: All prevalence ratios (PRs) were compared with large MSAs and adjusted for demographics and risk factors.

Purpose: The purpose of the study was to convert waist circumference (WC) measurements obtained by the World Health Organization (WHO-WC) method to the National Heart, Lung, and Blood Institute (NHLBI-WC) method.

Methods: During 2016, the National Health and Nutrition Examination Survey participants aged 20 years and older had two different WC measurements taken (n = 2405). The mean differences in the WC between the NHLBI-WC and WHO-WC measurements were calculated.

New York City Health and Nutrition Examination Survey (NYC HANES) was a population-based cross-sectional survey of NYC adults conducted twice, in 2004 and again in 2013-2014, to monitor the health of NYC adults 20 years or older. While blood pressure was measured in both surveys, an auscultatory mercury sphygmomanometer was used to measure blood pressure in clinics in 2004, and an oscillometric LifeSource UA-789AC monitor was used in homes in 2013-2014. To assess comparability of blood pressure results across both surveys, we undertook a randomized study comparing blood pressure (BP) readings by the two devices.

Objective This report compares five methods of waist circumference (WC) measurements: 1) the National Heart, Lung, and Blood Institute (NHLBI-WC); 2) the World Health Organization (WHO-WC); 3) the Multi-Ethnic Study of Atherosclerosis (MESA-WC) using Gulick II Plus tape; 4) the Multi-Ethnic Study of Atherosclerosis (MESA-WC) using Lufkin tape; and 5) assisted self-measurement over clothes (MESA-assisted). Method During 2016, measurements were obtained from 2,297 participants aged 20 and over, who participated in the National Health and Nutrition Examination Survey (NHANES). The mean differences and sensitivity and specificity for abdominal obesity (AO) were calculated between the NHLBI-WC (reference) and the other four WC measurements.

The accurate measurement of blood pressure (BP) is essential for the diagnosis and management of hypertension. Restricted use of mercury devices, increased use of oscillometric devices, discrepancies between clinic and out-of-clinic BP, and concerns about measurement error with manual BP measurement techniques have resulted in uncertainty for clinicians and researchers. The National Heart, Lung, and Blood Institute of the U.

Background: Measuring blood pressure (BP) requires an appropriate BP cuff size given measured mid-arm circumference (mid-AC).

Objective: To provide mid-AC means and percentiles for US population aged more than 3 years and examine the frequency distribution of mid-AC cuffed by Baum and Welch Allyn cuff systems.

Patients And Methods: The 2011-2016 National Health and Nutrition Examination Survey, a cross-sectional survey, was used to estimate mean mid-AC (n=24 723).

Health systems are well positioned to identify and control hypertension among their patients. However, almost one third of US adults with uncontrolled hypertension are currently receiving medical care and are unaware of being hypertensive. This study describes the development and validation of a tool that health systems can use to compare their reported hypertension prevalence with their expected prevalence.
