RESUMEN
Introduction: PCORnet, the National Patient-Centered Clinical Research Network, is a large research network of health systems that map clinical data to a standardized data model. In 2018, we expanded existing infrastructure to facilitate use for public health surveillance. We describe benefits and challenges of using PCORnet for surveillance and describe case studies. Methods: In 2018, infrastructure enhancements included addition of a table to store patients' residential zip codes and expansion of a modular program to generate population health statistics across conditions. Chronic disease surveillance case studies conducted in 2019 assessed atrial fibrillation (AF) and cirrhosis. In April 2020, PCORnet established an infrastructure to support COVID-19 surveillance with institutions frequently updating their electronic health record data. Results: By August 2023, 53 PCORnet sites (84%) had a 5-digit zip code available on at least 95% of their patient populations. Among 148,223 newly diagnosed AF patients eligible for oral anticoagulant (OAC) therapy, 43.3% were on any OAC (17.8% warfarin, 28.5% any novel oral anticoagulant) within a year of the AF diagnosis. Among 60,268 patients with cirrhosis (2015-2019), common documented etiologies included unknown (48%), hepatitis C infection (23%), and alcohol use (22%). During October 2022 through December 2023, across 34 institutions, the proportion of COVID-19 patients who were cared for in the inpatient setting was 9.1% among 887,051 adults aged 20 years or older and 6.0% among 139,148 children younger than 20 years. Conclusions: PCORnet provides important data that may augment traditional public health surveillance programs across diverse conditions. PCORnet affords longitudinal population health assessments among large catchments of the population with clinical, treatment, and geographic information, with capabilities to deliver rapid information needed during public health emergencies.

OBJECTIVES: Vaccination reduces the risk of acute coronavirus disease 2019 (COVID-19) in children, but it is less clear whether it protects against long COVID. We estimated vaccine effectiveness (VE) against long COVID in children aged 5 to 17 years. METHODS: This retrospective cohort study used data from 17 health systems in the RECOVER PCORnet electronic health record program for visits after vaccine availability. We examined both probable (symptom-based) and diagnosed long COVID after vaccination. RESULTS: The vaccination rate was 67% in the cohort of 1 037 936 children. The incidence of probable long COVID was 4.5% among patients with COVID-19, whereas diagnosed long COVID was 0.8%. Adjusted vaccine effectiveness within 12 months was 35.4% (95 CI 24.5-44.7) against probable long COVID and 41.7% (15.0-60.0) against diagnosed long COVID. VE was higher for adolescents (50.3% [36.6-61.0]) than children aged 5 to 11 (23.8% [4.9-39.0]). VE was higher at 6 months (61.4% [51.0-69.6]) but decreased to 10.6% (-26.8% to 37.0%) at 18-months. CONCLUSIONS: This large retrospective study shows moderate protective effect of severe acute respiratory coronavirus 2 vaccination against long COVID. The effect is stronger in adolescents, who have higher risk of long COVID, and wanes over time. Understanding VE mechanism against long COVID requires more study, including electronic health record sources and prospective data.

Objective: Vaccination reduces the risk of acute COVID-19 in children, but it is less clear whether it protects against long COVID. We estimated vaccine effectiveness (VE) against long COVID in children aged 5-17 years. Methods: This retrospective cohort study used data from 17 health systems in the RECOVER PCORnet electronic health record (EHR) Program for visits between vaccine availability, and October 29, 2022. Conditional logistic regression was used to estimate VE against long COVID with matching on age group (5-11, 12-17) and time period and adjustment for sex, ethnicity, health system, comorbidity burden, and pre-exposure health care utilization. We examined both probable (symptom-based) and diagnosed long COVID in the year following vaccination. Results: The vaccination rate was 56% in the cohort of 1,037,936 children. The incidence of probable long COVID was 4.5% among patients with COVID-19, while diagnosed long COVID was 0.7%. Adjusted vaccine effectiveness within 12 months was 35.4% (95 CI 24.5 - 44.5) against probable long COVID and 41.7% (15.0 - 60.0) against diagnosed long COVID. VE was higher for adolescents 50.3% [36.3 - 61.0]) than children aged 5-11 (23.8% [4.9 - 39.0]). VE was higher at 6 months (61.4% [51.0 - 69.6]) but decreased to 10.6% (-26.8 - 37.0%) at 18-months. Discussion: This large retrospective study shows a moderate protective effect of SARS-CoV-2 vaccination against long COVID. The effect is stronger in adolescents, who have higher risk of long COVID, and wanes over time. Understanding VE mechanism against long COVID requires more study, including EHR sources and prospective data. Article Summary: Vaccination against COVID-19 has a protective effect against long COVID in children and adolescents. The effect wanes over time but remains significant at 12 months. What's Known on This Subject: Vaccines reduce the risk and severity of COVID-19 in children. There is evidence for reduced long COVID risk in adults who are vaccinated, but little information about similar effects for children and adolescents, who have distinct forms of long COVID. What This Study Adds: Using electronic health records from US health systems, we examined large cohorts of vaccinated and unvaccinated patients <18 years old and show that vaccination against COVID-19 is associated with reduced risk of long COVID for at least 12 months.

RESUMEN
Importance: The 2017 Clinical Practice Guideline (CPG) for the diagnosis and management of pediatric hypertension (PHTN) categorizes a greater proportion of children with elevated blood pressure and PHTN, yet several barriers to CPG adherence have been noted. Objective: To assess adherence to the 2017 CPG for the diagnosis and management of PHTN and use of a clinical decision support (CDS) tool to calculate blood pressure percentiles. Design, Setting, and Participants: This cross-sectional study used electronic health record-extracted data from January 1, 2018, to December 31, 2019, among patients visiting 1 of 74 federally qualified health centers in AllianceChicago, a national Health Center Controlled Network. Children and adolescents (aged 3-17 years; hereinafter referred to as children) who attended at least 1 visit and had at least 1 blood pressure reading at or above the 90th percentile or diagnosis of elevated blood pressure or PHTN were eligible for data to be included in the analysis. Data were analyzed from September 1, 2020, to February 21, 2023. Exposures: Blood pressure at or above the 90th or 95th percentile. Main Outcomes and Measures: Diagnosis of PHTN (International Statistical Classification of Diseases and Related Health Problems, Tenth Revision [ICD-10], code I10) or elevated blood pressure (ICD-10 code R03.0) and CDS tool use; blood pressure management (antihypertensive medication, lifestyle counseling, referral); and follow-up visit attendance. Descriptive statistics described the sample and rates of guideline adherence. Logistic regression analyses identified patient- and clinic-level associations with guideline adherence. Results: The sample consisted of 23â¯334 children (54.9% boys; 58.6% White race; median age, 8 [IQR, 4-12] years). Guideline-adherent diagnosis was observed in 8810 children (37.8%) with blood pressure at or above the 90th percentile and 146 of 2542 (5.7%) with blood pressure at or above the 95th percentile at 3 or more visits. The CDS tool was used to calculate blood pressure percentiles in 10 524 cases (45.1%) and was associated with significantly greater odds of PHTN diagnosis (odds ratio, 2.14 [95% CI, 1.10-4.15]). Among 15 422 children with blood pressure at or above the 95th percentile, antihypertensive medication was prescribed to 831 (5.4%), lifestyle counseling was provided to 14â¯841 (96.2%), and blood pressure-related referrals were given to 848 (5.5%). Guideline-adherent follow-up was observed in 8651 of 19â¯049 children (45.4%) with blood pressure at or above the 90th percentile and 2598 of 15â¯164 (17.1%) with blood pressure at or above the 95th percentile. Differences in guideline adherence by patient- and clinic-level factors were observed. Conclusions and Relevance: In this study, fewer than 50% of children with elevated blood pressure had a guideline-adherent diagnosis code or attended guideline-adherent follow-up. Using a CDS tool was associated with guideline-adherent diagnosis, but the tool was underused. Further work is needed to understand how to best support implementation of tools promoting PHTN diagnosis, management, and follow-up.

Background: Elevated highly-sensitive cardiac troponin-T (hs-cTnT≥14 ng/L) and low ankle-brachial index (ABI<0.9) are risk factors for atherosclerotic cardiovascular diseases (ASCVD) but their joint effect on the risk of ASCVD events is unknown. Methods: We used data from the two population-based cohort studies, the Multi-Ethnic study of Atherosclerosis (MESA) and Cardiovascular Heart Study (CHS) among 10,897 participants free of CVD events at baseline (mean age 66.3 years, 44.7% males). Incident ASCVD was defined as CHD (fatal/non-fatal MI or revascularization), transient ischemic attack, or stroke,. Hazard ratio (HR) and 95% CI was calculated from a Cox regression model. Interaction on the additive scale was assessed using relative excess risk due to interaction (RERI) and interaction on the multiplicative scale was assessed by Likelihood ratio (LR) test. Results: At baseline (2000-2002 for MESA and 1989-1990 for CHS), 10.2% of participants had elevated hs-cTnT and 7.5% had low ABI. During a median follow-up of 13.6 years (interquartile range, 7.5-14.7 years), there were 2590 incident ASCVD and 1542 incident CHD events. The hazard of CHD and ASCVD was higher in participants with both elevated hs-cTnT and low ABI [HR(95% CI): CHD: 2.04 (1.45, 2.88), ASCVD: 2.05 (1.58, 2.66)] than those with only elevated hs-cTnT [CHD: 1.65 (1.37, 1.99), ASCVD: 1.67 (1.44, 1.99)] or only low ABI [CHD: 1.87 (1.52, 2.31), ASCVD: 1.67 (1.42, 1.97)]. Antagonistic multiplicative interaction was observed for CHD (LR test p-value=0.042) but not for ASCVD (LR test p-value =0.08). No significant additive interaction was detected for CHD and ASCVD (RERI p-value ≥0.23). Conclusion: The observed joint effect of elevated cTnT and low ABI on ASCVD risk was smaller (i.e., antagonistic interaction) than that expected by the combined independent effects of each risk factor.
RESUMEN
Background Arterial stiffness can be separated into 2 main mechanisms: (1) load-dependent stiffening from higher blood pressure and (2) structural stiffening due to remodeling of the vessel wall. The relationship between stiffness mechanisms and end organ damage is unknown. Methods and Results MESA (Multi-Ethnic Study of Atherosclerosis) participants with carotid ultrasound were included in this study (n=6147). Carotid pulse wave velocity (cPWV) was calculated to represent total stiffness. Structural stiffness was calculated by adjusting cPWV to a 120/80 mm Hg blood pressure with participant-specific models. Load-dependent stiffness was the difference of total and structural stiffness. Associations with incident chronic kidney disease (CKD), dementia, and mortality were assessed with adjusted Cox models. During 14.3±4.8 years of follow-up, 773 CKD events, 535 dementia events, and 1529 deaths occurred. Total cPWV was associated with mortality (hazard ratio [HR], per 1 m/s, 1.04 [95% CI, 1.01-1.08], P=0.02) and dementia (HR, 1.06 [95% CI, 1.01-1.12], P=0.03) but not CKD (HR, 1.03 [95% CI, 0.98-1.08], P=0.33). Structural cPWV was significantly associated with mortality (HR, 1.04 [95% CI, 1.00-1.08], P=0.04) but not CKD (HR, 1.00 [95% CI, 0.94-1.05], P=0.86) or dementia (HR, 1.06 [95% CI, 0.99-1.13], P=0.06). Load-dependent cPWV was significantly associated with CKD (HR, 1.38 [95% CI, 1.17-1.63], P<0.001) but not mortality (HR, 1.11 [95% CI, 0.99-1.25], P=0.07) or dementia (HR, 1.14 [95% CI, 0.94-1.38], P=0.19). Conclusions The mechanisms of arterial stiffness were associated with all-cause mortality and CKD. Structural stiffness was associated with all-cause mortality, and load-dependent stiffness was associated with CKD. Total stiffness was associated with dementia but load-dependent and structural stiffness were not.

Arterial stiffness progresses with age and is a predictor of adverse cardiovascular disease events. Studies examining associations of statin therapy with arterial stiffness have yielded mixed results. Associations between the duration and intensity of statin therapy and arterial stiffness have not been studied in a prospective multiethnic cohort. MESA participants (n = 1242) with statin medication use data at each exam (1-5) and who had undergone B-mode carotid ultrasound at baseline and at Exam 5 after (mean ± [SD]) 9.4 ± 0.5 years were analyzed. Carotid arterial stiffness was measured using the distensibility coefficient (DC) and Young's elastic modulus (YEM). Linear regression models were used to evaluate associations between DC and YEM and statin treatment duration and intensity. At baseline, participants were 66.5 ± 8.1 years old, 41% female, 36% White, 30% African American, 14% Chinese American, and 20% Hispanic. The mean baseline low-density lipoprotein cholesterol (LDL-C) was 149.5 ± 14.5 mg/dL. After adjusting for age, sex, race/ethnicity, and CVD risk factors, the percent changes in DC and YEM were found to not be significantly different in individuals on statin therapy at any combination of visits (1-4) compared to participants never on statin therapy (all p > 0.32). There were also no differences in the percent change in DC and YEM based on statin therapy intensity by quartile (all p > 0.14) over the 10-year follow-up period. Based on the aforementioned results, statin therapy was not associated with changes in carotid artery stiffness over nearly a decade of follow-up regardless of therapy duration or intensity.

RATIONALE & OBJECTIVE: Living in environments with low access to food may increase the risk of chronic diseases. We investigated the association of household distance to the nearest supermarket (as a measure of food access) with the incidence of hypertension, diabetes, and chronic kidney disease (CKD) in a metropolitan area of the United States. STUDY DESIGN: Retrospective cohort study. SETTING & PARTICIPANTS: 777,994 individuals without hypertension, diabetes, or CKD at baseline within the HealthLNK Data Repository, which contains electronic health records from 7 health care institutions in Chicago, Illinois. EXPOSURE: Zip code-level average distance between households and nearest supermarket. OUTCOME: Incidence of hypertension, diabetes, and CKD based on presence of ICD-9 code and/or blood pressure≥140/90mm Hg, hemoglobin A1c≥6.5%, and eGFR<60mL/min/1.73m2, respectively. ANALYTICAL APPROACH: Average distance to nearest supermarket was aggregated from street-level metrics for 56 Chicagoland zip codes. The cumulative incidence of hypertension, diabetes, and CKD from 2007-2012 was calculated for each zip code in patients free of these diseases in 2006. Spatial analysis of food access and disease incidence was performed using bivariate local indicator of spatial association (BiLISA) maps and bivariate local Moran I statistics. The relationship between supermarket access and outcomes was analyzed using logistic regression. RESULTS: Of 777,994 participants, 408,608 developed hypertension, 51,380 developed diabetes, and 56,365 developed CKD. There was significant spatial overlap between average distance to supermarket and incidence of hypertension and diabetes but not CKD. Zip codes with large average supermarket distances and high incidence of hypertension and diabetes were clustered in southern and western neighborhoods. Models adjusted only for neighborhood factors (zip code-level racial composition, access to vehicles, median income) revealed significant associations between zip code-level average distance to supermarket and chronic disease incidence. Relative to tertile 1 (shortest distance), ORs in tertiles 2 and 3, respectively, were 1.27 (95% CI, 1.23-1.30) and 1.38 (95% CI, 1.33-1.43) for diabetes, 1.03 (95% CI, 1.02-1.05) and 1.04 (95% CI, 1.02-1.06) for hypertension, and 1.18 (95% CI, 1.15-1.21) and 1.33 (95% CI, 1.29-1.37) for CKD. Models adjusted for demographic factors and health insurance showed significant and positive association with greater odds of incident diabetes (tertile 2: 1.29 [95% CI, 1.26-1.33]; tertile 3: 1.35 [95% CI, 1.31-1.39]) but lesser odds of hypertension (tertile 2: 0.95 [95% CI, 0.94-0.97]; tertile 3: 0.91 [95% CI, 0.89-0.92]) and CKD (tertile 2: 0.80 [95% CI, 0.78-0.82]; tertile 3: 0.73 [95% CI, 0.72-0.76]). After adjusting for both neighborhood and individual covariates, supermarket distance remained significantly associated with greater odds of diabetes and lesser odds of hypertension, but there was no significant association with CKD. LIMITATIONS: Unmeasured neighborhood and social confounding variables, zip code-level analysis, and limited individual-level information. CONCLUSIONS: There are significant disparities in supermarket proximity and incidence of hypertension, diabetes, and CKD in Chicago, Illinois. The relationship between supermarket access and chronic disease is largely explained by individual- and neighborhood-level factors.

Objectives: Hypertension affects 1 in 3 adults in the United States and disproportionately affects African Americans. Kaiser Permanente demonstrated that a "bundle" of evidence-based interventions significantly increased blood pressure control rates. This paper describes a multiyear process of developing the protocol for a trial of the Kaiser bundle for implementation in under-resourced urban communities experiencing cardiovascular health disparities during the planning phase of this biphasic award (UG3/UH3). Methods: The protocol was developed by a collaboration of faith-based community members, representatives from community health center practice-based research networks, and academic scientists with expertise in health disparities, implementation science, community-engaged research, social care interventions, and health informatics. Scientists from the National Institutes of Health and the other grantees of the Disparities Elimination through Coordinated Interventions to Prevent and Control Heart and Lung Disease Risk (DECIPHeR) Alliance also contributed to developing our protocol. Results: The protocol is a hybrid type 3 effectiveness-implementation study using a parallel cluster randomized trial to test the impact of practice facilitation on implementation of the Kaiser bundle in community health centers compared with implementation without facilitation. A central strategy to the Kaiser bundle is to coordinate implementation via faith-based and other community organizations for recruitment and navigation of resources for health-related social risks. Conclusions: The proposed research has the potential to improve identification, diagnosis, and control of blood pressure among under-resourced communities by connecting community entities and healthcare organizations in new ways. Faith-based organizations are a trusted voice in African American communities that could be instrumental for eliminating disparities.

Majority of previous studies showed no association between a single health behavior and arterial stiffness, but the benefit of simultaneously having multiple healthy behaviors (optimal lifestyle) on the progression of arterial stiffness is unknown. Among 2810 individuals (age 60.0 ± 9.4, 46.5% male), optimal lifestyle marker (yes/no) on four health behaviors (ie, BMI < 25 kg/m2 , never or former smoker, never or moderate drinker, exercised > 500 METS min/week) across four visits (≈ 5 years) were summed to create an optimal lifestyle score. Carotid arterial stiffness was measured using distensibility coefficient (DC) and Young's elastic modulus (YEM) at visit 1 and after a mean of 9.5 years (visit 5). The association of optimal lifestyle with 10-year percent change in DC and YEM was assessed using multiple linear regression. DC decreased by 5.3% and YEM increased by 24.4% over 10 years. Mean optimal lifestyle score was 9.4 ± 3.1 (range: 0-16). Individuals in quintiles 2-5 of optimal lifestyle score compared to quintile 1 (with the least optimal lifestyle score) did not show slower deceleration of DC [Q2, -0.3% (95% CI: -6.0, 5.4); Q3, -0.01% (-4.5, 4.5); Q4, -0.6% (-5.2, 3.9); Q5, -0.4% (-5.3, 4.4)], trend p-value = .82] or slower progression of YEM [Q2, 0.1% (-7.1, 7.3); Q3, -0.8% (-8.0, 6.5); Q4, 4.5% (-2.3, 11.3); Q5, -0.2% (-8.3, 7.9)], trend p-value = .49] after adjusting for risk factors. The association remained non-significant when stratified by categories of age, sex, race, BP control, and diabetes. Our findings indicate that optimal score on multiple health behaviors may not independently slow arterial stiffness progression.

BACKGROUND: Small-sized primary care practices, defined as practices with fewer than 10 clinicians, delivered the majority of outpatient visits in the USA. Statin therapy in high-risk individuals reduces atherosclerotic cardiovascular disease (ASCVD) events, but prescribing patterns in small primary care practices are not well known. This study describes statin treatment patterns in small-sized primary care practices and examines patient- and practice-level factors associated with lack of statin treatment. METHODS: We conducted a retrospective cohort analysis of statin-eligible patients from practices that participated in Healthy Hearts in the Heartland (H3), a quality improvement initiative aimed at improving cardiovascular care measures in small primary care practices. All statin-eligible adults who received care in one of 53 H3 practices from 2013 to 2016. Statin-eligible adults include those aged at least 21 with (1) clinical ASCVD, (2) low-density lipoprotein cholesterol (LDL-C) ≥ 190 mg/dL, or (3) diabetes aged 40-75 and with LDL-C 70-189 mg/dL. Eligible patients with no record of moderate- to high-intensity statin prescription are defined by ACC/AHA guidelines. RESULTS: Among the 13,330 statin-eligible adults, the mean age was 58 years and 52% were women. Overall, there was no record of moderate- to high-intensity statin prescription among 5,780 (43%) patients. Younger age, female sex, and lower LDL-C were independently associated with a lack of appropriate intensity statin therapy. Higher proportions of patients insured by Medicaid and having only family medicine trained physicians (versus having at least one internal medicine trained physician) at the practice were also associated with lower appropriate intensity statin use. Lack of appropriate intensity statin therapy was higher in independent practices than in Federally Qualified Health Centers (FQHCs) (50% vs. 40%, p value < 0.01). CONCLUSIONS: There is an opportunity for improved ASCVD risk reduction in small primary care practices. Statin treatment patterns and factors influencing lack of treatment vary by practice setting, highlighting the importance of tailored approaches to each setting.

Risk sexual behaviours are known as a threat to health and wellbeing of adolescents. Although there are standard sexual education curriculums in Thai schools, most schools use traditional teaching methods rather than participatory teaching activities. This study aimed to (i) develop 'Teen-Strong' programme by combining the concept of the World Health Organization's life skills programme with Thai sexual education curriculum and (ii) investigate the association of Teen-Strong programme with knowledge and decision-making regarding risky sexual behaviours and teenage pregnancy in Thai adolescents. The Teen-Strong programme was developed by means of experts review and cognitive interviewing process and evaluated in 66 adolescents in Grades 7-9 from six schools in southern Thailand. Twenty-six students were assigned to the experimental group (attended Teen-Strong programme and standard sexual education) and 40 to the control group (attended only the standard sexual education). A pre-post-test quasi-experimental design was used and the Teen-Strong questionnaire (TSQ) was administered to measure knowledge and decision-making at three time points: before (T1), immediately after (T2) and 1 month after (T3) attending the programme. A 2 × 3 mixed-design ANOVA was used to analyse the data. TSQ scores in the experimental and control groups were higher at T2 and T3 as compared with T1. Mean increase in TSQ scores at T2 and T3 compared with T1 were significantly higher in the experiment than the control group [T2 vs. T1: t (64) = 4.07, p-values < 0.0001; T3 vs. T1: t (64) = 3.32, p-values = 0.017]. This study showed that Teen-Strong programme could increase adolescent's knowledge and decision-making skills regarding risk sexual behaviours.
Sexual practices during adolescence are shown to cause teenage pregnancy and other threats to the health and wellbeing of adolescents in Thailand. Adolescent sexual education that considers the culture and environment where adolescents grow up is essential. Although there are sexual education programmes in Thai schools, most schools use traditional teaching methods (i.e. learning through memorization) rather than participatory teaching activities (i.e. learning through activities and sharing experiences from and with peers). We developed a programme called 'Teen-Strong' by combining participatory learning technique proposed by the World Health Organization with the Thai sexual education programme and evaluate whether this hybrid programme helped Thai adolescents in Grades 79 to better understand and avoid risky sexual behaviours. We found that adolescents who were involved in the Teen-Strong programme showed better knowledge and decision-making skills at avoiding risky sexual practices than adolescents who were not involved in the programme. Our findings show participatory sexual education programme could enhance adolescents' understanding of risky sexual practices and strategies to avoid these risky practices.

Pediatric hypertension is associated with significant target organ damage in children and cardiovascular morbidity in adulthood. Appropriate diagnosis and management per guideline recommendations are inconsistent. In this study, we determined the proportion of missed diagnosis of hypertension and prehypertension and appropriate follow-up in pediatric patients, stratified by sex, age, race/ethnicity, and weight status. Based on the electronic health record (EHR) data from eight federally qualified health centers, among 62,982 children aged 3 to 18 years, 6233 (10%) had at least one abnormal blood pressure (BP) measurement over twelve months. Among those children whose recorded BPs met the criteria for prehypertension (N = 6178), 14.6% had a diagnosis in the EHR. These children were more likely to be White and have obesity compared with children who met the criteria but were not diagnosed with prehypertension. Among those who met the criteria for hypertension (N = 55), 41.8% had a diagnosis of hypertension in the EHR. Being diagnosed with hypertension was not associated with any examined patient characteristics. Over eleven months, 2837 children had BP ≥ 95th percentile on ≥ 1 visit. Only 13% had guideline-adherent follow-up within 1 month and were more likely to be older, female, and of Hispanic ethnicity or "other" race. Over six months, 2902 children had BP ≥ 90th percentile on one visit. 41% had guideline-adherent follow-up within 6 months and were more likely to be older, of either White, Hispanic, Asian race, or Hispanic ethnicity. In a community-based setting, pediatric hypertension and prehypertension were persistently underdiagnosed with low adherence to recommended follow-up.

BACKGROUND: Though clinical practice guidelines are available, the diagnosis of pediatric hypertension (HTN) is often missed. Management may not follow guidelines due to the measurement challenges in children, complexity of interpreting youth blood pressure standards that are dependent on height, age, and sex, familiarity with diagnostic criteria, and variable comfort with management of pediatric HTN among providers. Evidence suggests that wide adoption and adherence to pediatric HTN guidelines would result in lower cardiovascular disease and kidney damage in adulthood. The proposed project will develop an implementation strategy package to increase adherence to clinical practice guidelines for pediatric HTN within safety-net community health centers (CHCs). The centerpiece of which is a provider-facing population panel management (PPM) tool and point-of-care clinical decision support (CDS). Prior research indicates that multiple discrete implementation strategies (e.g., stakeholder involvement, readiness planning, training, ongoing audit and feedback) are needed to institute practice- and provider-level adoption of such tools. METHODS: Using participatory research methods involving stakeholders from a practice-based research network of CHCs, with input from scientific advisors, the project aims to (1) employ user-centered design methods to tailor an existing CDS tool for use at the point of care and optimize cohort management with a PPM tool to support adherence to the latest pediatric HTN guidelines, and (2) use a stakeholder-driven method for selecting implementation strategies that support tool adoption and increase guideline-adherent physician behaviors. Multilevel process evaluation using surveys and key informant interview data will assess the acceptability, adoption, appropriateness, cost, and feasibility of the PPM tool and its multicomponent implementation strategy package. Usability testing will be conducted with the PPM tool to iteratively refine features and ensure proper functionality. DISCUSSION: The proposed research has the potential to improve identification, diagnosis, and management of HTN in primary care settings for high-risk youth by assisting healthcare providers in implementing the American Academy of Pediatrics' 2017 guidelines using an EHR-integrated PPM tool with CDS. Should the strategy package for PPM tool adoption be successful for pediatric HTN, findings will be translatable to other settings and PPM of other chronic cardiovascular conditions affecting overall population health.
RESUMEN
BACKGROUND: Oral anticoagulant (OAC) therapy is proven to be effective at reducing risk of stroke in patients with atrial fibrillation (AF). However, racial minorities with AF are less likely to be prescribed vitamin K anticoagulants (VKA). There is little information on the racial disparity in the prescription of the non-vitamin K oral anticoagulants (NOACs) and the associated risks of stroke and bleeding. METHODS: We used data from the Northwestern Medicine Enterprise Data Warehouse - a joint initiative across 11 Northwestern Medicine affiliated healthcare centers within metropolitan Chicago, Illinois. Newly diagnosed AF patients between Jan, 2011 and Dec, 2017 with CHA2DS2VASc (congestive heart failure, hypertension, age ≥75 years, diabetes, stroke/transient ischemic attack, vascular disease, age 65 to 74 years, female sex) score of 2 or more and no prior history of stroke or major bleeding were eligible. Logistic regression was used to examine differences in the prescription of any OAC and NOACs by race. Racial differences in the associations of NOACs prescription with incident stroke (a composite of ischemic and hemorrhagic stroke and cerebral embolism) and major bleeding were evaluated using Cox regression. RESULTS: Among 11,575 newly diagnosed AF patients with CHA2DS2VASc score of 2 or more, 48.7% (47.8-49.6) were on any OAC and among those 40.1% (38.8.3-41.4) received any NOACs. After adjusting for age, gender, income, insurance status, and stroke risk factors, the odds of receiving any OAC was .69 (95% CI: .58-.83) in blacks, .74 (.53-1.903) in Hispanics, and .75 (.58-.95) in Asians compared to whites. Among anticoagulated patients, blacks and Hispanics had significantly lower odds of receiving NOACs: .72 (.53-.97) and .53 (.29-.99), respectively. Use of NOACs, as compared to VKAs, was associated with significantly lower risk of stroke [.52(.31-.85)] and bleeding [.72(.54-.95)] in whites but not in non-whites [stroke: .71 (.22-2.31); bleeding .83(.43-1.57)] independent of other risk factors. CONCLUSIONS: Racial minorities with AF who are at risk of stroke were less likely to receive any OAC and NOACs specifically compared to whites even after accounting for insurance status, income, and stroke risk factors. Independent of other risk factors, use of NOACs as compared to VKA was associated with significantly lower risk of stroke and bleeding only in whites but not in non-whites.

The CHA2DS2-VASc and HAS-BLED scoring systems are used in patients with atrial fibrillation (AF) to estimate risk of stroke and bleeding, respectively. Both were developed in minimally diverse European populations and these scores have not yet been extensively studied in US whites and nonwhites. In a retrospective cohort study, we included patients with AF who received inpatient or outpatient care in a large integrated academic health system from 2011 to 2017. Cox proportional hazards were used to analyze associations between stroke and CHA2DS2-VASc score in AF patients not prescribed anticoagulation and between incident bleeding and HAS-BLED score in anticoagulated patients. After exclusions for previous stroke, the cohort included 21,648 patients with a mean age of 66.8 ± 15.8. Anticoagulation was prescribed in 52% of whites and 46% of nonwhites (p < 0.001) with a CHA2DS2-VASc score of ≥2. Mean CHA2DS2-VASc scores were 2.4 ± 1.6 in whites and 2.2 ± 1.6 in nonwhites and mean HAS-BLED scores was 1.5 ± 1.1 in whites and 1.3 ± 1.0 in nonwhites. After adjusting for baseline differences, the discriminative ability of CHA2DS2-VASc and HAS-BLED was similar in whites and nonwhites (pâ¯=â¯0.52, 0.33, respectively). The discriminative ability of HAS-BLED was similar in patients on vitamin K antagonists and direct oral anticoagulants. In conclusion, oral anticoagulation was prescribed less frequently in nonwhites. However, the discriminative ability of CHA2DS2-VASc and HAS-BLED were similar in whites and nonwhites.

There are few studies examining patterns in body mass index (BMI) and blood pressure (BP) and subsequent hypertensive disorders of pregnancy (HDPs). We examined the association of BMI (nâ¯=â¯1342) or BP (nâ¯=â¯2266) trajectories in the 5â¯years preceding birth with HDPs using adjusted logistic regression. Compared to normal-weight BMI and low-normal BP groups, membership to the overweight BMI group (OR: 2.95, 95%CI: 1.57-5.53, pâ¯=â¯0.001) and higher-normal (OR: 2.74, 95%CI:1.49-5.04, pâ¯=â¯0.001) and prehypertensive (OR:7.27, 95%CI: 3.29-16.06, pâ¯<â¯0.001) BP groups were associated with higher odds of HDPs. Our data suggest maintaining normal-weight and low-normal BP in the years preceding pregnancy may help avoid HDPs.

BACKGROUND AND AIMS: Long-term blood pressure variability (BPV) is associated with cardiovascular events independent of mean blood pressure (BP); however, little is known about its predictors. METHODS: Using data from the CARDIA study, we investigated the association between peak lung-function and long-term BPV in 2917 individuals (mean age 24.8 years, 45.3% males, 58.6% whites) who were not taking antihypertensive medications. Lung-function was measured using forced vital capacity (FVC) and forced expiratory volume in 1-s (FEV1) at years 0, 2, 5, 10 and 20 and the maximum score attained was considered as peak lung-function. Variability independent of the mean (VIM) and coefficient of variation (CV) of BP were calculated to quantify BPV since achieving peak lung-function across 9 visits over 30 years. RESULTS: In a multivariate linear regression models, individuals in the 2nd (-0.64â¯mmHg; 95% CI: -1.06, -0.19), 3rd (-0.96; -1.47, -0.45), and 4th (-0.85: -1.53, -0.17) quartiles of FVC had lower VIM of systolic BP than the those in quartile 1 (p-trendâ¯=â¯0.005). CV of systolic BP was also lower by -0.58 (-0.98, -0.19), -0.92 (-1.42, -0.43), and -0.74 (-1.40, -0.08) percentage points, in the three progressively higher quartiles of FVC compared to quartile 1 (p-trendâ¯=â¯0.008). Similar findings were observed when the outcome was diastolic BPV. There was no association of FEV1 and FEV1-to-FVC ratio with BPV. CONCLUSIONS: These findings suggest that smaller lung volume or restrictive lung disease during young adulthood, which result in lower peak FVC, may independently increase the risk of higher long-term BPV during middle adulthood.

The aims of this study are to assess the relationships of visit-to-visit blood pressure (BP) variability in young adulthood to hippocampal volume and integrity at middle age. We used data over 8 examinations spanning 25 years collected in the CARDIA study (Coronary Artery Risk Development in Young Adults) of black and white adults (age, 18-30 years) started in 1985 to 1986. Visit-to-visit BP variability was defined as by SDBP and average real variability (ARVBP, defined as the absolute differences of BP between successive BP measurements). Hippocampal tissue volume standardized by intracranial volume (%) and integrity assessed by fractional anisotropy were measured by 3-Tesla magnetic resonance imaging at the year-25 examination (n=545; mean age, 51 years; 54% women and 34% African Americans). Mean systolic BP (SBP)/diastolic BP levels were 110/69 mm Hg at year 0 (baseline), 117/73 mm Hg at year 25, and ARVSBP and SDSBP were 7.7 and 7.9 mm Hg, respectively. In multivariable-adjusted linear models, higher ARVSBP was associated with lower hippocampal volume (unstandardized regression coefficient [standard error] with 1-SD higher ARVSBP: -0.006 [0.003]), and higher SDSBP with lower hippocampal fractional anisotropy (-0.02 [0.01]; all P<0.05), independent of cumulative exposure to SBP during follow-up. Conversely, cumulative exposure to SBP and diastolic BP was not associated with hippocampal volume. There was no interaction by sex or race between ARVSBP or SDSBP with hippocampal volume or integrity. In conclusion, visit-to-visit BP variability during young adulthood may be useful in assessing the potential risk for reductions in hippocampal volume and integrity in midlife.

Importance: Data are sparse regarding which blood pressure (BP) components in young adulthood optimally determine cardiovascular disease (CVD) by middle age. Objectives: To assess which BP components best determine incident CVD events in young adults and determine whether these associations vary by race and age at BP measurement. Design, Setting, and Participants: Using data from the Coronary Artery Risk Development in Young Adults (CARDIA) study, this study assessed the longitudinal race-stratified associations between BP and cardiovascular outcomes. CARDIA is a community-based cohort that recruited black and white individuals (age range, 18-30 years) from March 26, 1985, through June 7, 1986. CARDIA followed up participants for up to 28 years, and 94% of the surviving cohort completed at least 1 telephone interview or examination from August 2009 through August 2014. Exposures: Blood pressures measubred at baseline (Y0) and 15 years later (Y15). Main Outcomes and Measures: Composite CVD events, including coronary heart disease, stroke, heart failure, and other vascular diseases. Results: A total of 4880 participants participated in the study (mean [SD] age, 24.9 [3.6] years at Y0 and 25.0 [3.6] years at Y15; 2223 male [45.6%] at Y0 and 1800 [44.2%] at Y15; 2657 female [54.4%] at Y0 and 2277 [55.8%] at Y0; 2473 black individuals [50.7%] at Y0 and 1994 [48.9%] at Y15; and 2407 white individuals [49.3%] at Y0 and 2083 [51.1%] at Y15). The mean SBP/DBP was 112/69 mm Hg in blacks and 109/68 mm Hg in whites at Y0 and 117/77 mm Hg in blacks and 110/72 mm Hg in whites at Y15. During a 25-year follow-up from Y0, 210 CVD events occurred (twice as many events in blacks [n = 140] compared with whites), of which 131 (87 in blacks) occurred after Y15. With adjustments for covariates, results from Cox proportional hazards models, including SBP and DBP, jointly suggested that, at Y0, SBP (hazard ratio [HR] per 1-SD increase, 1.32; 95% CI, 1.09-1.61) but not DBP (HR, 1.05; 95% CI, 0.88-1.26) was associated with CVD risk in blacks, whereas DBP (HR, 1.74; 95% CI, 1.21-2.50) but not SBP (HR, 0.82; 95% CI, 0.57-1.18) was associated with CVD risk in whites. At Y15, SBP was the strongest indicator of CVD in blacks (HR, 1.64; 95% CI, 1.25-2.16) and whites (HR, 1.67; 95% CI, 1.02-2.69). Conclusions and Relevance: This study questions the classic view that DBP is more able to identify future CVD events than SBP in all individuals younger than 50 years. In young adulthood, SBP in black individuals and DBP in white individuals were the most robust indicators of future CVD. In middle-age, SBP in both races identified risk of incident CVD.
