Association of Economic Policies With Hypertension Management and Control: A Systematic Review.

Importance: Economic policies have the potential to impact management and control of hypertension. Objectives: To review the evidence on the association between economic policies and hypertension management and control among adults with hypertension in the US. Evidence Review: A search was carried out of PubMed/MEDLINE, Cochrane Library, Embase, PsycINFO, CINAHL, EconLit, Sociological Abstracts, and Scopus from January 1, 2000, through November 1, 2023. Included were randomized clinical trials, difference-in-differences, and interrupted time series studies that evaluated the association of economic policies with hypertension management. Economic policies were grouped into 3 categories: insurance coverage expansion such as Medicaid expansion, cost sharing in health care such as increased drug copayments, and financial incentives for quality such as pay-for-performance. Antihypertensive treatment was measured as taking antihypertensive medications or medication adherence among those who have a hypertension diagnosis; and hypertension control, measured as blood pressure (BP) lower than  140/90 mm Hg or a reduction in BP. Evidence was extracted and synthesized through dual review of titles, abstracts, full-text articles, study quality, and policy effects. Findings: In total, 31 articles were included. None of the studies examined economic policies outside of the health care system. Of these, 16 (52%) assessed policies for insurance coverage expansion, 8 (26%) evaluated policies related to patient cost sharing for prescription drugs, and 7 (22%) evaluated financial incentive programs for improving health care quality. Of the 16 studies that evaluated coverage expansion policies, all but 1 found that policies such as Medicare Part D and Medicaid expansion were associated with significant improvement in antihypertensive treatment and BP control. Among the 8 studies that examined patient cost sharing, 4 found that measures such as prior authorization and increased copayments were associated with decreased adherence to antihypertensive medication. Finally, all 7 studies evaluating financial incentives aimed at improving quality found that they were associated with improved antihypertensive treatment and BP control. Overall, most studies had a moderate or low risk of bias in their policy evaluation. Conclusions and Relevance: The findings of this systematic review suggest that economic policies aimed at expanding insurance coverage or improving health care quality successfully improved medication use and BP control among US adults with hypertension. Future research is needed to investigate the potential effects of non-health care economic policies on hypertension control.

Enhancing availability of services to control hypertension through a team-based care approach that includes pharmacists.

BACKGROUND: Primary care physician (PCP) shortages are expected to increase. The Michigan Medicine Hypertension Pharmacists' Program uses a team-based care (TBC) approach to redistribute some patient care responsibilities from PCPs to pharmacists for patients with diagnosed hypertension. OBJECTIVE: This evaluation analyzed whether the Michigan Medicine Hypertension Pharmacists' Program increased the availability of hypertension management services and described facilitators that addressed barriers to program sustainability and replicability. METHODS: We conducted a retrospective observational study that used a mixed methods approach. We examined the availability of hypertension management services using the number of pharmacists' referrals of patients to other services and the number of PCP appointments. We analyzed qualitative interviews with program staff and site-level quantitative data to examine the program's impact on the availability of services, the impact of TBC that engaged pharmacists, and program barriers and facilitators. RESULTS: Patients who visited a pharmacist had fewer PCP visits over 3- and 6-month periods compared to a matched comparison group that did not see a pharmacist and were 1.35 times more likely to receive a referral to a specialist within a 3-month period. Support from leaders and physicians, shared electronic health record access, and financial backing emerged as leading factors for program sustainability and replicability. CONCLUSION: Adding pharmacists to the care team reduced the number of PCP appointments per patient while increasing the availability of hypertension management services; this may in turn improve PCPs' availability. Similar models may be sustainable and replicable by relying on organizational buy-in, accessible infrastructure, and financing.

Trends in Drug Spending of Oral Anticoagulants for Atrial Fibrillation, 2014-2021.

INTRODUCTION: This study documents cost trends in oral anticoagulants (OAC) in patients with newly diagnosed atrial fibrillation. METHODS: Using MarketScan databases, the mean annual patients' out-of-pocket costs, insurance payments, and the proportion of patients initiating OAC within 90 days from atrial fibrillation diagnosis were calculated from July 2014 to June 2021. Costs of OACs (apixaban, dabigatran, edoxaban, rivaroxaban, and warfarin) and the payments by three insurance types (commercial payers, Medicare, and Medicaid) were calculated. Patients' out-of-pocket costs and insurance payments were adjusted to 2021 prices. Joinpoint regression models were used to test trends of outcomes and average annual percent changes (AAPC) were reported. Data analyses were performed in 2022-2023. RESULTS: From July 2014 to June 2021, the mean annual out-of-pocket costs of any OAC increased for commercial insurance (AAPC 3.0%) and Medicare (AAPC 5.1%) but decreased for Medicaid (AAPC -3.3%). The mean annual insurance payments for any OAC significantly increased for all insurance groups (AAPC 13.1% [95% CI 11.3-15.0] for Medicare; AAPC 11.8% [95% CI 8.0-15.6] for commercial insurance; and AAPC 16.3% [95% CI 11.3-21.4] for Medicaid). The initiation of any OAC increased (AAPC 7.3% for commercial insurance; AAPC 10.2% for Medicare; AAPC 5.3% for Medicaid). CONCLUSIONS: There was a substantial increase in the overall cost burden of OACs and OAC initiation rates in patients with newly diagnosed atrial fibrillation in 2014-2021; these findings provide insights into the current and anticipated impact of rising drug prices on patients' and payers' financial burden.

Hypertension Prevalence and Control Among U.S. Women of Reproductive Age.

INTRODUCTION: Hypertension is a risk factor for cardiovascular disease, a leading cause of death among women of reproductive age (women aged 18-44 years). This study estimated hypertension prevalence and control among women of reproductive age at the national and state levels using electronic health record data. METHODS: Nonpregnant women of reproductive age were included in this cross-sectional study using 2019 IQVIA Ambulatory Electronic Medical Records - U.S. national data (analyzed in 2023). Suspected hypertension was identified using any of these criteria: ≥1 hypertension diagnosis code, ≥2 blood pressure readings ≥140/90 mmHg on separate days, or ≥1 antihypertensive medication. Among women of reproductive age with hypertension, the latest blood pressure in 2019 was used to identify hypertension control (blood pressure <140/90 mmHg). Estimates were age standardized and stratified by race or Hispanic ethnicity, region, and states with sufficient data. Tukey tests compared estimates by race or Hispanic ethnicity, region, and comorbidities. RESULTS: Among 2,125,084 women of reproductive age (62.1% White, 8.8% Black, and 29.1% other [including Hispanic, Asian, other, or unknown]) with a mean age of 31.7 years, hypertension prevalence was 14.5%. Of those with hypertension, 71.9% had controlled blood pressure. Black women of reproductive age had a higher hypertension prevalence (22.3% vs 14.4%, p<0.05) but lower control (60.6% vs 74.0%, p<0.05) than White women of reproductive age. State-level hypertension prevalence ranged from 13.7% (Massachusetts) to 36% (Alabama), and control ranged from 82.9% (Kansas) to 59.2% (the District of Columbia). CONCLUSIONS: This study provides the first state-level estimates of hypertension control among women of reproductive age. Electronic health record data complements traditional hypertension surveillance data and provides further information for efforts to prevent and manage hypertension among women of reproductive age.

State-Level Hypertension Prevalence and Control Among Adults in the U.S.

INTRODUCTION: Improving hypertension control is a national priority. Electronic health record data have the potential to augment traditional surveillance systems. This study aimed to assess hypertension prevalence and control at the state level using a previously established electronic health record-based phenotype for hypertension. METHODS: Adult patients (N=11,031,368) were included from the IQVIA ambulatory electronic medical record-U.S. 2019 data set. IQVIA ambulatory electronic medical record comprises electronic health records from >100,000 providers and includes patients from every U.S. state and Washington DC. Authors compared hypertension prevalence and control estimates against those from the Behavioral Risk Factor Surveillance System 2019. Results were age-standardized and stratified by state and sociodemographic characteristics. Statistical analyses were conducted in 2022-2023. RESULTS: IQVIA ambulatory electronic medical record-U.S. patients had a median age of 55 years, and 56.7% were women. Overall age-standardized hypertension prevalence was higher in IQVIA ambulatory electronic medical record-U.S. (35.0%) than in the Behavioral Risk Factor Surveillance System (29.7%), however, state-level geographic patterns were similar, with the highest burden in the South and Appalachia. Similar patterns were also observed by sociodemographic characteristics in both data sets: hypertension prevalence was higher in older age groups (than younger), men (than women), and Black patients (than other races). Hypertension control varied widely across states: among states with >1% data coverage, control rates were lowest in Nevada (51.1%), Washington DC (52.0%), and Mississippi (55.2%); highest in Kansas (73.4%), New Jersey (72.3%), and Iowa (71.9%). CONCLUSIONS: This study provided the first-ever estimates of hypertension control for all states and Washington DC. Electronic health record-based surveillance could support hypertension prevention and control efforts at the state level.

Leveraging Electronic Health Records to Construct a Phenotype for Hypertension Surveillance in the United States.

BACKGROUND: Hypertension is an important risk factor for cardiovascular diseases. Electronic health records (EHRs) may augment chronic disease surveillance. We aimed to develop an electronic phenotype (e-phenotype) for hypertension surveillance. METHODS: We included 11,031,368 eligible adults from the 2019 IQVIA Ambulatory Electronic Medical Records-US (AEMR-US) dataset. We identified hypertension using three criteria, alone or in combination: diagnosis codes, blood pressure (BP) measurements, and antihypertensive medications. We compared AEMR-US estimates of hypertension prevalence and control against those from the National Health and Nutrition Examination Survey (NHANES) 2017-18, which defined hypertension as BP ≥130/80 mm Hg or ≥1 antihypertensive medication. RESULTS: The study population had a mean (SD) age of 52.3 (6.7) years, and 56.7% were women. The selected three-criteria e-phenotype (≥1 diagnosis code, ≥2 BP measurements of ≥130/80 mm Hg, or ≥1 antihypertensive medication) yielded similar trends in hypertension prevalence as NHANES: 42.2% (AEMR-US) vs. 44.9% (NHANES) overall, 39.0% vs. 38.7% among women, and 46.5% vs. 50.9% among men. The pattern of age-related increase in hypertension prevalence was similar between AEMR-US and NHANES. The prevalence of hypertension control in AEMR-US was 31.5% using the three-criteria e-phenotype, which was higher than NHANES (14.5%). CONCLUSIONS: Using an EHR dataset of 11 million adults, we constructed a hypertension e-phenotype using three criteria, which can be used for surveillance of hypertension prevalence and control.

Economics of Team-Based Care for Blood Pressure Control: Updated Community Guide Systematic Review.

INTRODUCTION: This paper examined the recent evidence from economic evaluations of team-based care for controlling high blood pressure. METHODS: The search covered studies published from January 2011 through January 2021 and was limited to those based in the U.S. and other high-income countries. This yielded 35 studies: 23 based in the U.S. and 12 based in other high-income countries. Analyses were conducted from May 2021 through February 2023. All monetary values reported are in 2020 U.S. dollars. RESULTS: The median intervention cost per patient per year was $438 for U.S. studies and $299 for all studies. The median change in healthcare cost per patient per year after the intervention was -$140 for both U.S. studies and for all studies. The median net cost per patient per year was $439 for U.S. studies and $133 for all studies. The median cost per quality-adjusted life year gained was $12,897 for U.S. studies and $15,202 for all studies, which are below a conservative benchmark of $50,000 for cost-effectiveness. DISCUSSION: Intervention cost and net cost were higher in the U.S. than in other high-income countries. Healthcare cost averted did not exceed intervention cost in most studies. The evidence shows that team-based care for blood pressure control is cost-effective, reaffirming the favorable cost-effectiveness conclusion reached in the 2015 systematic review.

Trends in Lipid-Lowering Prescriptions: Increasing Use of Guideline-Concordant Pharmacotherapies, U.S., 2017‒2022.

INTRODUCTION: Almost one third of U.S. adults have elevated low-density lipoprotein cholesterol, increasing their risk of atherosclerotic cardiovascular disease. The 2018 American College of Cardiology/American Heart Association Multisociety Cholesterol Management Guideline recommends maximally tolerated statin for those at increased atherosclerotic cardiovascular disease risk and add-on therapies (ezetimibe and PCSK9 inhibitors) in those at very high risk and low-density lipoprotein cholesterol ≥70 mg/dL. Prescription fill trends are unknown. METHODS: Using national outpatient retail prescription data from the first quarter of 2017 to the first quarter of 2022, authors determined counts of patients who filled low-, moderate-, or high-intensity statins alone and with add-on therapies. The overall percentage change and joinpoint regression were used to assess trends. Analyses were conducted in March 2022-May 2022. RESULTS: During the first quarter of 2017 to the first quarter of 2022, patients filling a statin increased by 25.0%, with the greatest increase in high-intensity statins (64.1%, range=6.6-10.9 million). Low-intensity statins decreased by 29.2% (range=3.3-2.4 million). Concurrent fills of high-intensity statin and ezetimibe rose by 210% to 579,012 patients by the first quarter of 2022, with an increase in slope by the first quarter of 2019 for all statin intensities (p<0.01). Concurrent fills of a statin and PCSK9 inhibitor increased to 2,629, 16,169, and 28,651 by the first quarter of 2022 for low-, moderate-, and high-intensity statins, respectively. For patients on all statin intensities and PCSK9 inhibitor, there were statistically significant increases in slope in the second quarter of 2019 and decreases in the first quarter of 2020. CONCLUSIONS: Patients filling moderate- and high-intensity statins and add-on ezetimibe and PCSK9 inhibitors have increased, indicating uptake of guideline-concordant lipid-lowering therapies. Improvements in the initiation and continuity of these therapies are important for atherosclerotic cardiovascular disease prevention.

Pharmacist Interventions for Medication Adherence: Community Guide Economic Reviews for Cardiovascular Disease.

INTRODUCTION: Adherence to medications for cardiovascular disease and its risk factors is less than optimal, although greater adherence to medication has been shown to reduce the risk factors for cardiovascular disease. This paper examines the economics of tailored pharmacy interventions to improve medication adherence for cardiovascular disease prevention and management. METHODS: Literature from inception of databases to May 2019 was searched, yielding 29 studies for cardiovascular disease prevention and 9 studies for cardiovascular disease management. Analyses were done from June 2019 through May 2020. All monetary values are in 2019 U.S. dollars. RESULTS: The median intervention cost per patient per year was $246 for cardiovascular disease prevention and $292 for cardiovascular disease management. The median change in healthcare cost per person per year due to the intervention was -$355 for cardiovascular disease prevention and -$2,430 for cardiovascular disease management. The median total cost per person per year was -$89 for cardiovascular disease prevention, with a median return on investment of 0.01. The median total cost per person per year for cardiovascular disease management was -$1,080, with a median return on investment of 7.52, and 6 of 7 estimates indicating reduced healthcare cost averted exceeded intervention cost. For cardiovascular disease prevention, the median cost per quality-adjusted life year gained was $11,298. There were no cost effectiveness studies for cardiovascular disease management. DISCUSSION: The evidence shows that tailored pharmacy-based interventions to improve medication adherence are cost effective for cardiovascular disease prevention. For cardiovascular disease management, healthcare cost averted exceeds the cost of implementation for a favorable return on investment from a healthcare systems perspective.
