RESUMO
Introduction: This analysis is a part of ongoing quality improvement efforts aiming at improving hypertension control among various racial minority groups seen in a large outpatient practice with a special focus on two war refugee populations, the Hmong and the Somali populations. Method: Deidentified medical records were reviewed for adult hypertensive patients who had an outpatient encounter with a hypertension diagnosis during the years 2015 through 2019. The study outcome was the rate of uncontrolled hypertension, defined as systolic blood pressure ≥140 mm Hg or diastolic blood pressure ≥90 mm Hg, and stratified by race, age, and gender. Results: There were 752,504 patient records representing 259,824 unique patients (mean age 61 ± 13 years) with 49.1% women, 82.1% white 8.3% African American, 4% Asian, 1.6% Hispanic, Somali 0.6%, and 0.2% Hmong. Hmong men had the highest rate of uncontrolled HTN (33.6%) followed by African American (31.3%) then Somali (29.2%). Among women, African Americans had the highest rate (28.6%) followed by Hmong (28.5%) then Somali (25.7%). In all races except Somali, the rate of uncontrolled hypertension was highest in the 18-29 age group, decreased progressively over the next several decades, then increased again in the ≥70 age group. Conclusion: Hmong, African American, and Somali groups have the highest rates of uncontrolled hypertension. Efforts to address hypertension management need to be tailored to the specific characteristics of each racial group and to target young adults.
RESUMO
Importance: Terminal digit preference has been shown to be associated with inaccurate blood pressure (BP) recording. Objective: To evaluate whether converting from manual BP measurement with aneroid sphygmomanometers to automated BP measurement was associated with terminal digit preference, mean levels of recorded BP, and the rate at which hypertension was diagnosed. Design, Setting, and Participants: This quality improvement study was conducted from May 9, 2021, to March 24, 2022, using interrupted time series analysis of medical record data from 11 primary care clinics in a single health care system from April 2008 to April 2015. The study population was patients aged 18 to 75 years who had their BP measured and recorded at least once during the study period. Exposures: Manual BP measurement before April 2012 vs automated BP measurement with the Omron HEM-907XL monitor from May 2012 to April 2015. Main Outcomes and Measures: The main outcome was the distribution of terminal digits and mean systolic BP (SBP) values obtained during 4 years of manual measurement vs 3 years of automated measurement, assessed using a generalized linear mixed regression model with a random intercept for clinic and adjusted for seasonal fluctuations and patient demographic and clinical characteristics. Results: The study included 1â¯541â¯227 BP measurements from 225â¯504 unique patients during the entire study period, with 849â¯978 BP measurements from 165â¯137 patients (mean [SD] age, 47.1 [15.2] years; 58.2% female) during the manual measurement period and 691â¯249 measurements from 149â¯080 patients (mean [SD] age, 48.4 [15.3] years; 56.3% female) during the automated measurement period. With manual measurement, 32.8% of SBP terminal digits were 0 (20% was the expected value because nursing staff was instructed to record BP to the nearest even digit). This proportion decreased to 12.4% during the automated measurement period (expected value, 10%) when both even and odd digits were to be recorded. After automated measurement was implemented, the mean SBP estimated with statistical modeling increased by 5.09 mm Hg (95% CI, 4.98-5.19 mm Hg). Fewer BP values recorded during the automated than the manual measurement period were below 140/90 mm Hg (69.9% vs 84.3%; difference, -14.5%; 95% CI, -14.6% to -14.3%) and below 130/80 mm Hg (42.1% vs 60.0%; difference, -17.9%; 95% CI, -18.0% to -17.7%). The proportion of patients with a diagnosis of hypertension was 4.3 percentage points higher (23.4% vs 19.1%) during the automated measurement period. Conclusions and Relevance: In this quality improvement study, automated BP measurement was associated with decreased terminal digit preference and significantly higher mean BP levels. The method of BP measurement was also associated with the rate at which hypertension was diagnosed. These findings may have implications for pay-for-performance programs, which may create an incentive to record BP levels that meet a particular goal and a disincentive to adopt automated measurement of BP.

BACKGROUND: Health systems and providers across America are increasingly employing telehealth technologies to better serve medically underserved low-income, minority, and rural populations at the highest risk for health disparities. The Patient-Centered Outcomes Research Institute (PCORI) has invested US $386 million in comparative effectiveness research in telehealth, yet little is known about the key early lessons garnered from this research regarding the best practices in using telehealth to address disparities. OBJECTIVE: This paper describes preliminary lessons from the body of research using study findings and case studies drawn from PCORI seminal patient-centered outcomes research (PCOR) initiatives. The primary purpose was to identify common barriers and facilitators to implementing telehealth technologies in populations at risk for disparities. METHODS: A systematic scoping review of telehealth studies addressing disparities was performed. It was guided by the Arksey and O'Malley Scoping Review Framework and focused on PCORI's active portfolio of telehealth studies and key PCOR identified by study investigators. We drew on this broad literature using illustrative examples from early PCOR experience and published literature to assess barriers and facilitators to implementing telehealth in populations at risk for disparities, using the active implementation framework to extract data. Major themes regarding how telehealth interventions can overcome barriers to telehealth adoption and implementation were identified through this review using an iterative Delphi process to achieve consensus among the PCORI investigators participating in the study. RESULTS: PCORI has funded 89 comparative effectiveness studies in telehealth, of which 41 assessed the use of telehealth to improve outcomes for populations at risk for health disparities. These 41 studies employed various overlapping modalities including mobile devices (29/41, 71%), web-based interventions (30/41, 73%), real-time videoconferencing (15/41, 37%), remote patient monitoring (8/41, 20%), and store-and-forward (ie, asynchronous electronic transmission) interventions (4/41, 10%). The studies targeted one or more of PCORI's priority populations, including racial and ethnic minorities (31/41, 41%), people living in rural areas, and those with low income/low socioeconomic status, low health literacy, or disabilities. Major themes identified across these studies included the importance of patient-centered design, cultural tailoring of telehealth solutions, delivering telehealth through trusted intermediaries, partnering with payers to expand telehealth reimbursement, and ensuring confidential sharing of private information. CONCLUSIONS: Early PCOR evidence suggests that the most effective health system- and provider-level telehealth implementation solutions to address disparities employ patient-centered and culturally tailored telehealth solutions whose development is actively guided by the patients themselves to meet the needs of specific communities and populations. Further, this evidence shows that the best practices in telehealth implementation include delivery of telehealth through trusted intermediaries, close partnership with payers to facilitate reimbursement and sustainability, and safeguards to ensure patient-guided confidential sharing of personal health information.

OBJECTIVE: To evaluate the cost-effectiveness of screening for depression in patients with acute coronary syndrome (ACS) and no history of depression. METHODS: Cost-effectiveness analysis of a randomized trial enrolling 1500 patients with ACS between 2013 and 2017. Patients were randomized to no screening, screening and notifying the primary care provider (PCP), and screening, notifying the PCP, and providing enhanced depression treatment. Outcomes measured were Healthcare utilization, costs, and incremental cost-effectiveness ratios. RESULTS: 7.1% of patients screened positive for depressive symptoms. There was no significant difference in usage of mental health services, cardiovascular tests and procedures, and medications. Mean total costs in No Screen group ($7440), in Screen, Notify, and Treat group ($6745), and in Screen and Notify group ($6204). The difference was only significant in the Screen and Notify group versus the No Screen group (-$1236, 95% confidence interval -$2388 to -$96). Because mean QALYs were higher (+0.003 QALY in Screen and Notify; +0.004 QALYs in Screen, Notify, and Treat) and mean total costs were lower in both intervention groups, these interventions were cost-effective. There was substantial uncertainty because confidence intervals around cost differences were wide and QALY effects were small. CONCLUSION: Depression screening strategies for patients with ACS may be modestly cost-effective.

The COVID-19 pandemic is a public health crisis, having killed more than 514 000 US adults as of March 2, 2021. COVID-19 mitigation strategies have unintended consequences on managing chronic conditions such as hypertension, a leading cause of cardiovascular disease and health disparities in the United States. During the first wave of the pandemic in the United States, the combination of observed racial/ethnic inequities in COVID-19 deaths and social unrest reinvigorated a national conversation about systemic racism in health care and society. The 4th Annual University of Utah Translational Hypertension Symposium gathered frontline clinicians, researchers, and leaders from diverse backgrounds to discuss the intersection of these 2 critical social and public health phenomena and to highlight preexisting disparities in hypertension treatment and control exacerbated by COVID-19. The discussion underscored environmental and socioeconomic factors that are deeply embedded in US health care and research that impact inequities in hypertension. Structural racism plays a central role at both the health system and individual levels. At the same time, virtual healthcare platforms are being accelerated into widespread use by COVID-19, which may widen the divide in healthcare access across levels of wealth, geography, and education. Blood pressure control rates are declining, especially among communities of color and those without health insurance or access to health care. Hypertension awareness, therapeutic lifestyle changes, and evidence-based pharmacotherapy are essential. There is a need to improve the implementation of community-based interventions and blood pressure self-monitoring, which can help build patient trust and increase healthcare engagement.

Uncontrolled hypertension is a leading contributor to cardiovascular disease. A cluster-randomized trial in 16 primary care clinics showed that 12 months of home blood pressure telemonitoring and pharmacist management lowered blood pressure more than usual care (UC) for 24 months. We report cardiovascular events (nonfatal myocardial infarction, nonfatal stroke, hospitalized heart failure, coronary revascularization, and cardiovascular death) and costs over 5 years of follow-up. In the telemonitoring intervention (TI group, n=228), there were 15 cardiovascular events (5 myocardial infarction, 4 stroke, 5 heart failure, 1 cardiovascular death) among 10 patients. In UC group (n=222), there were 26 events (11 myocardial infarction, 12 stroke, 3 heart failure) among 19 patients. The cardiovascular composite end point incidence was 4.4% in the TI group versus 8.6% in the UC group (odds ratio, 0.49 [95% CI, 0.21-1.13], P=0.09). Including 2 coronary revascularizations in the TI group and 10 in the UC group, the secondary cardiovascular composite end point incidence was 5.3% in the TI group versus 10.4% in the UC group (odds ratio, 0.48 [95% CI, 0.22-1.08], P=0.08). Microsimulation modeling showed the difference in events far exceeded predictions based on observed blood pressure. Intervention costs (in 2017 US dollars) were $1511 per patient. Over 5 years, estimated event costs were $758 000 in the TI group and $1 538 000 in the UC group for a return on investment of 126% and a net cost savings of about $1900 per patient. Telemonitoring with pharmacist management lowered blood pressure and may have reduced costs by avoiding cardiovascular events over 5 years.

The diagnosis and management of hypertension, a common cardiovascular risk factor among the general population, have been based primarily on the measurement of blood pressure (BP) in the office. BP may differ considerably when measured in the office and when measured outside of the office setting, and higher out-of-office BP is associated with increased cardiovascular risk independent of office BP. Self-measured BP monitoring, the measurement of BP by an individual outside of the office at home, is a validated approach for out-of-office BP measurement. Several national and international hypertension guidelines endorse self-measured BP monitoring. Indications include the diagnosis of white-coat hypertension and masked hypertension and the identification of white-coat effect and masked uncontrolled hypertension. Other indications include confirming the diagnosis of resistant hypertension and detecting morning hypertension. Validated self-measured BP monitoring devices that use the oscillometric method are preferred, and a standardized BP measurement and monitoring protocol should be followed. Evidence from meta-analyses of randomized trials indicates that self-measured BP monitoring is associated with a reduction in BP and improved BP control, and the benefits of self-measured BP monitoring are greatest when done along with cointerventions. The addition of self-measured BP monitoring to office BP monitoring is cost-effective compared with office BP monitoring alone or usual care among individuals with high office BP. The use of self-measured BP monitoring is commonly reported by both individuals and providers. Therefore, self-measured BP monitoring has high potential for improving the diagnosis and management of hypertension in the United States. Randomized controlled trials examining the impact of self-measured BP monitoring on cardiovascular outcomes are needed. To adequately address barriers to the implementation of self-measured BP monitoring, financial investment is needed in the following areas: improving education and training of individuals and providers, building health information technology capacity, incorporating self-measured BP readings into clinical performance measures, supporting cointerventions, and enhancing reimbursement.

BACKGROUND: Elevated depressive symptoms among survivors of acute coronary syndromes (ACS) confer recurrent cardiovascular events and mortality, worse quality of life, and higher healthcare costs. While multiple scientific groups advise routine depression screening for ACS survivors, no randomized trials exist to inform this screening recommendation. We aimed to assess the effect of screening for depression on change in quality of life over 18â¯months among ACS patients. METHODS: The Comparison of Depression Identification after Acute Coronary Syndrome on Quality of Life and Cost Outcomes (CODIACS-QoL) trial is a pragmatic, 3-arm trial that randomized ACS patients to 1) systematic depression screening using the 8-item Patient Health Questionnaire (PHQ-8) and if positive screen (PHQ-8â¯≥â¯10), notification of primary care providers (PCPs) and invitation to participate in centralized, patient-preference, stepped depression care (Screen, Notify, and Treat, Nâ¯=â¯499); 2) systematic depression screening and PCP notification only (Screen and Notify, Nâ¯=â¯501); and 3) usual care (No Screen, Nâ¯=â¯500). Adults hospitalized for ACS in the previous 2-12â¯months without prior history of depression were eligible for participation. Key outcomes will be quality-adjusted life years (primary), cost of health care utilization, and depression-free days across 18â¯months. RESULTS: A total of 1500 patients were randomized in the CODIACS-QOL trial (28.3% women; 16.3% Hispanic; mean age 65.9 (11.5) years). Only 7% of ACS survivors had elevated depressive symptoms. CONCLUSIONS: Using a novel randomization schema and pragmatic design principles, the CODIACS-QoL trial achieved its enrollment target. Eventual results of this trial will inform future depression screening recommendations in cardiac patients. TRIAL REGISTRATION: ClinicalTrials.gov (NCT01993017).

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.S. National Institutes of Health convened a working group of clinicians and researchers in October 2017 to review data on BP assessment among adults in clinical practice and clinic-based research. In this report, the authors review the topics discussed during a 2-day meeting including the current state of knowledge on BP assessment in clinical practice and clinic-based research, knowledge gaps pertaining to current BP assessment methods, research and clinical needs to improve BP assessment, and the strengths and limitations of using BP obtained in clinical practice for research and quality improvement activities.

BACKGROUND: Pharmacist-managed (team-based) care for hypertension with home blood pressure monitoring support interventions have been widely studied and shown to be effective in improving rates of hypertension control and lowering blood pressure; however, few studies have evaluated the economic considerations related to bringing these programs into usual practice. OBJECTIVE: To analyze the economic outcomes of the Blood Pressure Telemonitoring and Pharmacist Management on Blood Pressure (Hyperlink) study, a cluster randomized controlled trial which used home blood pressure telemonitoring and pharmacist case management to achieve better blood pressure control in patients with uncontrolled hypertension. METHODS: A prospective analysis compared differences in medical costs and encounters in the Hyperlink telemonitoring intervention and usual care groups in the 12 months pre- and post-enrollment using medical and pharmacy insurance claims from a health care sector perspective. Generalized estimating equation models were used to estimate differences between groups over time. These results, combined with previously published prospective study results on intervention costs and blood pressure outcomes, were used to estimate cost-effectiveness measures for blood pressure control and reduction. FINDINGS: Total medical costs in the intervention group were lower compared with the usual care group by an average of $281 per person, but this difference was not statistically significant. Clinic-based office visit, radiology, pharmacy, and hospital costs were also non-significantly lower in the intervention group. Statistically significant differences were found in lipid-related laboratory costs (higher) and in hypertension- (higher) and lipid-related (lower) pharmacy costs. Patterns in medical costs were similar for medical encounters. On average, the intervention cost $7337 per person achieving hypertension control and $139 or $265 per mm Hg reduction in systolic or diastolic blood pressure, respectively. CONCLUSIONS: Home blood pressure monitoring and pharmacist case management to improve hypertension care can be implemented without increasing, and potentially reducing, overall medical care costs.
RESUMO
OBJECTIVES: The Hyperlink trial tested a 12-month intervention of home blood pressure (BP) telemonitoring with pharmacist case management in adults with uncontrolled hypertension. The intervention resulted in improved BP control compared with usual care at both 6 (72% vs. 45%; P < 0.001) and 12 months (71% vs. 53%; P = 0.005). We sought to investigate factors contributing to intervention success. DESIGN: Mixed-methods analysis of process of care data, patient focus groups, and pharmacist interviews. PARTICIPANTS: Data from 228 intervention patients were examined from the original 450 patients randomly assigned from 16 primary care clinics. Five patient focus groups and 4 pharmacist interviews were conducted to ascertain the patient and pharmacist perspective. Focus group and interview data were coded, and themes relevant to pharmacists were identified. OUTCOME MEASURES: Home BP readings of less than 135/85 mm Hg and patient focus group and pharmacist interview themes. RESULTS: Mean BP at the intake visit was 148/85 mm Hg. Antihypertensive medications were adjusted in 10% of patients at the initial in-person visit, 33% at phone visit 1, 36% at phone visit 2, and 19% at phone visit 3. Thereafter, medication changes declined. The mean home BP for patients at the first phone visit was 136/80 mm Hg, 126/74 mm Hg at 3 months, and 123/73 mm Hg at 5 months, with little change thereafter. Key components of success from patient and pharmacist interviews included a strong patient-pharmacist relationship, individualized treatment plans, and frequent phone contact with the pharmacist. CONCLUSION: Frequent adjustments to the antihypertensive treatment regimen based on home BP telemonitoring resulted in rapid lowering of BP. Our results suggest that an intensive telephone-based intervention with the key components of medication adjustments, a strong patient and pharmacist relationship, and individualized treatment plans can achieve BP control in only 3 months in many patients with uncontrolled hypertension.

BACKGROUND: Randomized trials can compare economic as well as clinical outcomes, but economic data are difficult to collect. Linking clinical trial data with Medicare claims could provide novel information on health care utilization and cost. METHODS: We linked data from Medicare claims of women ≥65 years old who had Medicare fee-for-service coverage with their clinical data from the Women's Health Initiative trials of conjugated equine estrogens plus medroxyprogesterone acetate (CEE+MPA) versus placebo and of CEE-alone versus placebo. The primary outcome was total Medicare spending during the intervention phase of the trial, and the secondary outcomes were spending on diseases hypothesized a priori to be sensitive to the effects of hormone therapy. RESULTS: In the CEE+MPA trial, 4,557 participants ≥65 years old were included. Women randomly assigned to CEE+MPA had 4% higher mean Medicare spending overall ($45,690 vs $43,920, P = .08) but 0.5% lower spending for hormone-sensitive diseases ($3,526 vs $3,547, P = .07), with 73% higher spending for coronary heart disease (P = .045) and 122% higher spending for pulmonary embolism (P = .026). In the CEE-alone trial, 3,107 participants were included. Total spending among women randomly assigned to CEE was 3.3% higher ($75,411 vs $72,997, P = .16), and 1.7% higher spending for hormone-sensitive diseases ($5,213 vs $5,127, P = .57), but with 39% lower spending for hip fracture (p<0.03). CONCLUSIONS: Menopausal hormone therapy increased spending for some diseases, but decreased spending for others. These offsetting effects led to modest (3%-4%), nonsignificant increases in overall spending among women aged 65 years and older.

The 24th annual conference of the Health Care Systems Research Network (HCSRN, formerly the HMO Research Network), held April 11-13, 2018, in Minneapolis, Minnesota, attracted 357 attendees. The HCSRN is a consortium of 18 community-based research organizations embedded in or affiliated with large health care delivery systems. Its annual research conference, held since 1994, is a unique venue that brings diverse stakeholders (eg, research teams, clinicians, patients, funders) together to explore a range of health research topics and scientific findings, with a unifying goal of connecting applied research to real-world care delivery for the betterment of individual and community health. The 2018 conference was hosted by Minneapolis-based HealthPartners Institute and organized around 3 tracks: Research & Results, Practical Application, and Data Science & Informatics. Themes of the 4 plenary, 7 panel, 36 oral abstract, and 111 poster presentations included the learning health system, the opioid epidemic, health disparities, high costs of care, informing population health policy with evidence, and how to use storytelling to present data to inspire change, among others.
RESUMO
INTRODUCTION: Our objective was to compare Medicare claims to physician review and adjudication of medical records for identifying venous thromboembolism (VTE), and to assess VTE incidence, recurrence, and mortality in a large national cohort of post-menopausal women followed up to 19years. MATERIALS AND METHODS: We used detailed clinical data from the Women's Health Initiative (WHI) linked to Medicare claims. Agreement between data sources was evaluated among 16,003 women during 1993-2010. A claims-based definition was selected to analyze VTE occurrence and impact among 71,267 women during 1993-2012. RESULTS: Our VTE definition had 83% sensitivity. Positive predictive value was 69% when all records were included, and 94% after limiting Medicare records to those with a WHI hospitalization adjudicated. Annualized VTE incidence was 4.06/1000person-years (PY), recurrence was 5.30/100PY, and both rates varied by race/ethnicity. Post-VTE mortality within 1year was 22.49% from all causes, including 1.01% from pulmonary embolism, 10.40% from cancer, and 11.08% from other causes. Cancer-related VTE compared to non-cancer VTE had significantly (p<0.001) higher recurrence (9.86/100PY vs. 4.43/100PY) and mortality from all causes (45.89% vs. 12.28%), but not from pulmonary embolism (0.40% vs. 1.27%). CONCLUSIONS: Medicare claims compared reasonably well to physician adjudication. The combined data sources provided new insights about VTE burden and prognosis in older women.

INTRODUCTION: Team-based interventions for hypertension care have been widely studied and shown effective in improving hypertension outcomes. Few studies have evaluated long-term effects of these interventions; none have assessed broad-scale implementation. This study estimates the prospective health, economic, and budgetary impact of universal adoption of a team-based care intervention model that targets people with treated but uncontrolled hypertension in the U.S. METHODS: Analysis was conducted in 2014-2015 using a microsimulation model, constructed with various data sources from 1948 to 2014, designed to evaluate prospective cardiovascular disease (CVD)-related interventions in the U.S. POPULATION: Ten-year primary outcomes included prevalence of uncontrolled hypertension; incident myocardial infarction, stroke, CVD events, and CVD-related mortality; intervention and net medical costs by payer; productivity; and quality-adjusted life years. RESULTS: About 4.7 million (13%) fewer people with uncontrolled hypertension and 638,000 prevented cardiovascular events would be expected over 10 years. Assuming $525 per enrollee, implementation would cost payers $22.9 billion, but $25.3 billion would be saved in averted medical costs. Estimated net cost savings for Medicare approached $5.8 billion. Net costs were especially sensitive to intervention costs, with break-even thresholds of $300 (private), $450 (Medicaid), and $750 (Medicare). CONCLUSIONS: Nationwide adoption of team-based care for uncontrolled hypertension could have sizable effects in reducing CVD burden. Based on the study's assumptions, the policy would be cost saving from the perspective of Medicare and may prove to be cost effective from other payers' perspectives. Expected net cost savings for Medicare would more than offset expected net costs for all other insurers.

BACKGROUND: Exposure to interpersonal violence, namely verbal and physical abuse, is a highly prevalent threat to women's health and well-being. Among older, post-menopausal women, several researchers have characterized a possible bi-directional relationship of abuse exposure and diminished physical functioning. However, studies that prospectively examine the relationship between interpersonal abuse exposure and physical functioning across multiple years of observation are lacking. To address this literature gap, we prospectively evaluate the association between abuse exposure and physical functioning in a large, national cohort of post-menopausal women across 12 years of follow-up observation. METHODS: Multivariable logistic regression was used to measure the adjusted association between experiencing abuse and physical function score at baseline in 154,902 Women's Health Initiative (WHI) participants. Multilevel modeling, where the trajectories of decline in physical function were modeled as a function of time-varying abuse exposure, was used to evaluate the contribution of abuse to trajectories of physical function scores over time. RESULT: Abuse was prevalent among WHI participants, with 11 % of our study population reporting baseline exposure. Verbal abuse was the most commonly reported abuse type (10 %), followed by combined physical and verbal abuse (1 %), followed by physical abuse in the absence of verbal abuse (0.2 %). Abuse exposure (all types) was associated with diminished physical functioning, with women exposed to combined physical and verbal abuse presenting baseline physical functioning scores consistent with non-abused women 20 years senior. Results did not reveal a differential rate of decline over time in physical functioning based on abuse exposure. CONCLUSIONS: Taken together, our findings suggest a need for increased awareness of the prevalence of abuse exposure among postmenopausal women; they also underscore the importance of clinician's vigilance in their efforts toward the prevention, early detection and effective intervention with abuse exposure, including verbal abuse exposure, in post-menopausal women. Given our findings related to abuse exposure and women's diminished physical functioning at WHI baseline, our work illuminates a need for further study, particularly the investigation of this association in younger, pre-menopausal women so that the temporal ordering if this relationship may be better understood.

INTRODUCTION: Elevated blood pressure in childhood may predict increased cardiovascular risk in young adulthood. The Task Force on the Diagnosis, Evaluation and Treatment of High Blood pressure in Children and Adolescents recommends that blood pressure be measured in children aged 3 years or older at all health care visits. Guidelines from both Bright Futures and the Expert Panel of Integrated Guidelines for Cardiovascular Health and Risk Reduction in Children and Adolescents recommend annual blood pressure screening. Adherence to these guidelines is unknown. METHODS: We conducted a cross-sectional study to assess compliance with blood pressure screening recommendations in 2 integrated health care delivery systems. We analyzed electronic health records of 103,693 subjects aged 3 to 17 years. Probability of blood pressure measurement documented in the electronic health record was modeled as a function of visit type (well-child vs nonwell-child); patient age, sex, race/ethnicity, and body mass index; health care use; insurance type; and type of office practice or clinic department (family practice or pediatrics). RESULTS: Blood pressure was measured at 95% of well-child visits and 69% of nonwell-child outpatient visits. After adjusting for potential confounders, the percentage of nonwell-child visits with measurements increased linearly with patient age (P < .001). Overall, the proportion of children with annual blood pressure measurements was high and increased with age. Family practice clinics were more likely to adhere to blood pressure measurement guidelines compared with pediatric clinics (P < .001). CONCLUSION: These results show good compliance with recommendations for routine blood pressure measurement in children and adolescents. Findings can inform the development of EHR-based clinical decision support tools to augment blood pressure screening and recognition of prehypertension and hypertension in pediatric patients.

OBJECTIVES: Despite the significant prevalence of elevated blood pressure (BP) and body mass index (BMI) in children, few studies have assessed their combined impact on healthcare costs. This study estimates healthcare costs related to BP and BMI in children and adolescents. STUDY DESIGN: Prospective dynamic cohort study of 71,617 children aged 3 to 17 years with 208,800 child years of enrollment in integrated health systems in Colorado or Minnesota between January 1, 2007, and December 31, 2011. METHODS: Generalized linear models were used to calculate standardized annual estimates of total, inpatient, outpatient, and pharmacy costs, outpatient utilization, and receipt of diagnostic and evaluation tests associated with BP status and BMI status. Results: Total annual costs were significantly lower in children with normal BP ($736, SE = $15) and prehypertension ($945, SE = $10) than children with hypertension ($1972, SE = $74) (P <.001, each comparison), adjusting for BMI. Total annual cost for children below the 85th percentile of BMI ($822, SE = $8) was significantly lower than for children between the 85th and 95th percentiles ($954, SE = $45) and for children at or above the 95th percentile ($937, SE = $13) (P <.001, each), adjusting for HT. CONCLUSIONS: This study shows strong associations of prehypertension and hypertension, independent of BMI, with healthcare costs in children. Although BMI status was also statistically significantly associated with costs, the major influence on cost in this large cohort of children and adolescents was BP status. Costs related to elevated BMI may be systematically overestimated in studies that do not adjust for BP status.

BACKGROUND: Integrated guidelines on cardiovascular health and risk reduction in children issued in 2011 newly recommended universal screening for dyslipidemia in children at 9 to 11 years and 17 to 21 years. METHODS AND RESULTS: We determined the frequency and results of lipid testing in 301 080 children and adolescents aged 3 to 19 enrolled in 3 large US health systems in 2007 to 2010 before the 2011 guidelines were issued. Overall, 9.8% of the study population was tested for lipids. The proportion tested varied by body mass index percentile (5.9% of normal weight, 10.8% of overweight, and 26.9% of obese children) and age (8.9% of 9- to 11-year olds and 24.3% of 17- to 19-year olds). In normal weight individuals, 2.8% of 9- to 11-year olds and 22.0% of 17- to 19-year olds were tested. In multivariable models, age and body mass index category remained strongly associated with lipid testing. Sex, race, ethnicity, and blood pressure were weakly associated with testing. Abnormal lipid levels were found in 8.6% for total cholesterol, 22.5% for high-density lipoprotein-cholesterol, 12.0% for non-high-density lipoprotein-cholesterol, 8.0% for low-density lipoprotein-cholesterol, and 21% for triglycerides (age, 10-19 years). There was a strong and graded association of abnormal lipid levels with body mass index, particularly for high-density lipoprotein-cholesterol and triglycerides (2- to 6-fold higher odds ratio in obese when compared with that in normal weight children). CONCLUSIONS: Lipid screening was uncommon in 9- to 11-year olds and was performed in a minority of 17- to 19-year olds during 2007 to 2010. These data serve as a benchmark for assessing change in practice patterns after the new recommendations for pediatric lipid screening and management.

BACKGROUND: Data collected as part of routine clinical practice could be used to detect cardiovascular outcomes in pragmatic clinical trials or clinical registry studies. The reliability of claims data for documenting outcomes is unknown. METHODS AND RESULTS: We linked records of Women's Health Initiative (WHI) participants aged ≥65 years to Medicare claims data and compared hospitalizations that had diagnosis codes for acute myocardial infarction or coronary revascularization with WHI outcomes adjudicated by study physicians. We then compared the hazard ratios for active versus placebo hormone therapy based solely on WHI-adjudicated events with corresponding hazard ratios based solely on claims data for the same hormone trial participants. Agreement between WHI-adjudicated outcomes and Medicare claims was good for the diagnosis of myocardial infarction (κ, 0.71-0.74) and excellent for coronary revascularization (κ, 0.88-0.91). The hormone:placebo hazard ratio for clinical myocardial infarction was 1.31 (95% confidence interval, 1.03-1.67) based on WHI outcomes and 1.29 (95% confidence interval, 1.00-1.68) based on Medicare data. The hazard ratio for coronary revascularization was 1.09 (95% confidence interval, 0.88-1.35) based on WHI outcomes and 1.10 (95% confidence interval, 0.89-1.35) based on Medicare data. The differences between hazard ratios derived from WHI and Medicare data were not significant in 1000 bootstrap replications. CONCLUSIONS: Medicare claims may provide useful data on coronary heart disease outcomes among patients aged ≥65 years in clinical research studies.
