Antihypertensive and Statin Medication Adherence Among Medicare Beneficiaries.

INTRODUCTION: Medication adherence is important for optimal management of chronic conditions, including hypertension and hypercholesterolemia. This study describes adherence to antihypertensive and statin medications, individually and collectively, and examines variation in adherence by demographic and geographic characteristics. METHODS: The 2017 prescription drug event data for beneficiaries with Medicare Part D coverage were assessed. Beneficiaries with a proportion of days covered ≥80% were considered adherent. Adjusted prevalence ratios were estimated to quantify the associations between demographic and geographic characteristics and adherence. Adherence estimates were mapped by county of residence using a spatial empirical Bayesian smoothing technique to enhance stability. Analyses were conducted in 2019‒2021. RESULTS: Among the 22.5 million beneficiaries prescribed antihypertensive medications, 77.1% were adherent; among the 16.1 million prescribed statin medications, 81.9% were adherent; and among the 13.5 million prescribed antihypertensive and statin medications, 70.3% were adherent to both. Adherence varied by race/ethnicity: American Indian/Alaska Native (adjusted prevalence ratio=0.83, 95% confidence limit=0.82, 0.842), Hispanic (adjusted prevalence ratio=0.90, 95% confidence limit=0.90, 0.91), and non-Hispanic Black (adjusted prevalence ratio=0.87, 95% confidence limit=0.86, 0.87) beneficiaries were less likely to be adherent than non-Hispanic White beneficiaries. County-level adherence ranged across the U.S. from 25.7% to 88.5% for antihypertensive medications, from 36.0% to 93.8% for statin medications, and from 20.8% to 92.9% for both medications combined and tended to be the lowest in the southern U.S. CONCLUSIONS: This study highlights opportunities for efforts to remove barriers and support medication adherence, especially among racial/ethnic minority groups and within the regions at greatest risk for adverse cardiovascular outcomes.

COVID-19 Cases and Hospitalizations Among Medicare Beneficiaries With and Without Disabilities - United States, January 1, 2020-November 20, 2021.

Approximately 27% of adults in the United States live with a disability,* some of whom qualify for Medicare benefits. Persons with disabilities are at increased risk for severe COVID-19-associated outcomes compared with the general population (1); however, existing studies have limited generalizability† or only pertain to a specific disability (e.g., intellectual) (2). Older age is also associated with COVID-19-associated hospitalization and death, but the extent to which age might contribute to increased risk for severe COVID-19-associated outcomes among persons with disabilities is unknown (3). To describe the impact of COVID-19 on persons with disabilities and whether and how age contributes to disease rates, CDC assessed COVID-19 cases and hospitalizations during January 2020-November 2021, among Centers for Medicare & Medicaid Services (CMS) Medicare beneficiaries aged ≥18 years who were either eligible because of a disability (disability-eligible§) or only eligible because of age ≥65 years (age-eligible). COVID-19 incidence and hospitalization rates were higher in the disability-eligible group (10,978 and 3,148 per 100,000 population, respectively) throughout the study period compared with the age-eligible group (8,102 and 2,129 per 100,000 population, respectively). Both COVID-19 incidence and hospitalization rates increased with age in both disability- and age-eligible beneficiaries. American Indian or Alaska Native (AI/AN) persons had the highest disability-eligible (4,962 per 100,000) and age-eligible (5,024 per 100,000) hospitalization rates. Among all other racial and ethnic groups, hospitalization rates were higher among disability-eligible than among age-eligible patients. COVID-19 incidence and hospitalization rates among disability-eligible Medicare beneficiaries were disproportionally higher than rates among age-eligible beneficiaries. Collection of disability status as a core demographic variable in public health surveillance data and identification, as well as the addition of disability questions in other existing data sources can guide research and development of interventions for persons with disabilities. Efforts to increase access to and use of COVID-19 prevention and treatment strategies, including activities that support equitable vaccine access regardless of the substantial challenges that older adults and persons with disability face, are critical to reducing severe COVID-19-associated outcomes among these groups.

Prescription Smoking-Cessation Medication Fills and Spending, 2009-2019.

INTRODUCTION: Smoking is the leading cause of preventable disease and death. However, effective medicines, including prescription medications often covered by health insurance, are available to aid cessation. METHODS: Trends of 7 U.S. Food and Drug Administration-approved prescription medications for smoking cessation during 2009-2019 (before and during Affordable Care Act implementation), including fill counts and spending (total and patient, adjusted to 2019 U.S. dollars), were assessed among U.S. adults aged ≥18 years. Symphony Health's Integrated Dataverse combines data on >90% of outpatient prescription fills with market purchasing data to create national estimates. Analyses were conducted in 2021. RESULTS: Annually, total fills (spending) decreased from 3.7 million ($577 million) in 2009 to 2.5 million ($465 million) in 2013 and increased to 4.5 million ($1.279 billion) in 2019; patient spending decreased from $174 million (30% of total annual spending) in 2009 to $54 million (4%) in 2019. Comparing 2009 with 2019, the total spending per fill increased by 80% (from $157 to $282), whereas patient spending per fill decreased by 75% (from $47 to $12). The total spending per fill for branded products increased by 175% (from $166 to $459) and decreased by 41% (from $75 to $44) for generic products. Branded product percentage decreased from 89% to 57%. CONCLUSIONS: Total fills and spending decreased from 2009 to 2013 and then increased through 2019, whereas patient spending decreased. Earlier studies suggest possible reasons for these trends, such as gradual implementation of federal requirements for insurance coverage of cessation medications and reduced cost sharing and financial barriers.

Tracking Cardiac Rehabilitation Utilization in Medicare Beneficiaries: 2017 UPDATE.

PURPOSE: This study updates cardiac rehabilitation (CR) utilization data in a cohort of Medicare beneficiaries hospitalized for CR-eligible events in 2017, including stratification by select patient demographics and state of residence. METHODS: We identified Medicare fee-for-service beneficiaries who experienced a CR-eligible event and assessed their CR participation (≥1 CR sessions in 365 d), engagement, and completion (≥36 sessions) rates through September 7, 2019. Measures were assessed overall, by beneficiary characteristics and state of residence, and by primary (myocardial infarction; coronary artery bypass surgery; heart valve repair/replacement; percutaneous coronary intervention; or heart/heart-lung transplant) and secondary (angina; heart failure) qualifying event type. RESULTS: In 2017, 412 080 Medicare beneficiaries had a primary CR-eligible event and 28.6% completed ≥1 session of CR within 365 d after discharge from a qualifying event. Among beneficiaries who completed ≥1 CR session, the mean total number of sessions was 25 ± 12 and 27.6% completed ≥36 sessions. Nebraska had the highest enrollment rate (56.1%), with four other states also achieving an enrollment rate >50% and 23 states falling below the overall rate for the United States. CONCLUSIONS: The absolute enrollment, engagement, and program completion rates remain low among Medicare beneficiaries, indicating that many patients did not benefit or fully benefit from a class I guideline-recommended therapy. Additional research and continued widespread adoption of successful enrollment and engagement initiatives are needed, especially among identified populations.

Disparities in COVID-19 Vaccination Coverage Between Urban and Rural Counties - United States, December 14, 2020-April 10, 2021.

Approximately 60 million persons in the United States live in rural counties, representing almost one fifth (19.3%) of the population.* In September 2020, COVID-19 incidence (cases per 100,000 population) in rural counties surpassed that in urban counties (1). Rural communities often have a higher proportion of residents who lack health insurance, live with comorbidities or disabilities, are aged ≥65 years, and have limited access to health care facilities with intensive care capabilities, which places these residents at increased risk for COVID-19-associated morbidity and mortality (2,3). To better understand COVID-19 vaccination disparities across the urban-rural continuum, CDC analyzed county-level vaccine administration data among adults aged ≥18 years who received their first dose of either the Pfizer-BioNTech or Moderna COVID-19 vaccine, or a single dose of the Janssen COVID-19 vaccine (Johnson & Johnson) during December 14, 2020-April 10, 2021 in 50 U.S. jurisdictions (49 states and the District of Columbia [DC]). Adult COVID-19 vaccination coverage was lower in rural counties (38.9%) than in urban counties (45.7%) overall and among adults aged 18-64 years (29.1% rural, 37.7% urban), those aged ≥65 years (67.6% rural, 76.1% urban), women (41.7% rural, 48.4% urban), and men (35.3% rural, 41.9% urban). Vaccination coverage varied among jurisdictions: 36 jurisdictions had higher coverage in urban counties, five had higher coverage in rural counties, and five had similar coverage (i.e., within 1%) in urban and rural counties; in four jurisdictions with no rural counties, the urban-rural comparison could not be assessed. A larger proportion of persons in the most rural counties (14.6%) traveled for vaccination to nonadjacent counties (i.e., farther from their county of residence) compared with persons in the most urban counties (10.3%). As availability of COVID-19 vaccines expands, public health practitioners should continue collaborating with health care providers, pharmacies, employers, faith leaders, and other community partners to identify and address barriers to COVID-19 vaccination in rural areas (2).

Medicaid Medical Costs Associated with Hypertension by Diabetes Status among Women in Alabama.

Though a high proportion of Medicaid population in Alabama are women, little is known about their economic burdens of diabetes and hypertension. We used Alabama Medicaid claims data of 16,107 female enrollees aged 19-64 years to estimate per-capita total annual medical costs of hypertension by diabetes status. Hypertension prevalence was 60.0% and 17.3% among those with and without diabetes. The estimated annual medical cost for enrollees with hypertension was $6,689 (in 2017 $), of which $2,369 was associated with having hypertension. The hypertension-associated excess costs were $2,646 and $2,378 for enrollees with and without diabetes. All subgroups such as Blacks and those with Charlson Comorbidity Index ≥ 1, had higher medical costs when they had a combination of hypertension and diabetes compared with having diabetes without hypertension. Hypertension and diabetes increased medical costs substantially, and the findings can inform decision makers about effective resource utilizations for prevention and treatment strategies.

State and Regional Variation in Prescription- and Payment-Related Promoters of Adherence to Blood Pressure Medication.

INTRODUCTION: Medication adherence can improve hypertension management. How blood pressure medications are prescribed and purchased can promote or impede adherence. METHODS: We used comprehensive dispensing data on prescription blood pressure medication from Symphony Health's 2017 Integrated Dataverse to assess how prescription- and payment-related factors that promote medication adherence (ie, fixed-dose combinations, generic formulations, mail order, low-cost or no-copay medications) vary across US states and census regions and across the market segments (grouped by patient age, prescriber type, and payer type) responsible for the greatest number of blood pressure medication fills. RESULTS: In 2017, 706.5 million prescriptions for blood pressure medication were filled, accounting for $29.0 billion in total spending (17.0% incurred by patients). As a proportion of all fills, factors that promoted adherence varied by state: fixed-dose combinations (from 5.8% in Maine to 17.9% in Mississippi); generic formulations (from 95.2% in New Jersey to 98.4% in Minnesota); mail order (from 4.7% in Rhode Island to 14.5% in Delaware); and lower or no copayment (from 56.6% in Utah to 72.8% in California). Furthermore, mean days' supply per fill (from 43.1 in Arkansas to 63.8 in Maine) and patient spending per therapy year (from $38 in Hawaii to $76 in Georgia) varied. Concentration of adherence factors differed by market segment. Patients aged 18 to 64 with a primary care physician prescriber and Medicaid coverage had the lowest concentration of fixed-dose combination fills, mean days' supply per fill, and patient spending per therapy year. Patients aged 65 years or older with a primary care physician prescriber and commercial insurance had the highest concentration of fixed-dose combinations fills and mail order fills. CONCLUSION: Addressing regional and market segment variation in factors promoting blood pressure medication adherence may increase adherence and improve hypertension management.

Health and Budgetary Impact of Achieving 10-Year U.S. Sodium Reduction Targets.

INTRODUCTION: This study estimates the health, economic, and budgetary impact resulting from graduated sodium reductions in the commercially produced food supply of the U.S., which are consistent with draft U.S. Food and Drug Administration voluntary guidance and correspond to Healthy People 2020 objectives and the 2015-2020 Dietary Guidelines for Americans. METHODS: Reduction in mean U.S. dietary sodium consumption to 2,300 mg/day was implemented in a microsimulation model designed to evaluate prospective cardiovascular disease-related policies in the U.S. POPULATION: The analysis was conducted in 2018-2020, and the microsimulation model was constructed using various data sources from 1948 to 2018. Modeled outcomes over 10 years included prevalence of systolic blood pressure ≥140 mmHg; incident myocardial infarction, stroke, cardiovascular disease events, and cardiovascular disease-related mortality; averted medical costs by payer in 2017 U.S. dollars; and productivity. RESULTS: Reducing sodium consumption is expected to reduce the number of people with systolic blood pressure ≥140 mmHg by about 22% and prevent approximately 895.2 thousand cardiovascular disease events (including 218.9 thousand myocardial infarctions and 284.5 thousand strokes) and 252.5 thousand cardiovascular disease-related deaths over 10 years in the U.S. Savings from averted disease costs are expected to total almost $37 billion-most of which would be attributed to Medicare ($18.4 billion) and private insurers ($13.4 billion)-and increased productivity from reduced disease burden and premature mortality would account for another $18.2 billion in gains. CONCLUSIONS: Systemic sodium reductions in the U.S. food supply can be expected to produce substantial health and economic benefits over a 10-year period, particularly for Medicare and private insurers.

Tracking Cardiac Rehabilitation Participation and Completion Among Medicare Beneficiaries to Inform the Efforts of a National Initiative.

BACKGROUND: Despite cardiac rehabilitation (CR) being shown to improve health outcomes among patients with heart disease, its use has been suboptimal. In response, the Million Hearts Cardiac Rehabilitation Collaborative developed a road map to improve CR use, including increasing participation rates to ≥70% by 2022. This observational study provides current estimates to measure progress and identifies the populations and regions most at risk for CR service underutilization. METHODS AND RESULTS: We identified Medicare fee-for-service beneficiaries who were CR eligible in 2016, and assessed CR participation (≥1 CR session attended), timely initiation (participation within 21 days of event), and completion (≥36 sessions attended) through 2017. Measures were assessed overall, by beneficiary characteristics and geography, and by primary CR-qualifying event type (acute myocardial infarction hospitalization; coronary artery bypass surgery; heart valve repair/replacement; percutaneous coronary intervention; or heart/heart-lung transplant). Among 366 103 CR-eligible beneficiaries, 89 327 (24.4%) participated in CR, of whom 24.3% initiated within 21 days and 26.9% completed CR. Eligibility was highest in the East South Central Census Division (14.8 per 1000). Participation decreased with increasing age, was lower among women (18.9%) compared with men (28.6%; adjusted prevalence ratio: 0.91 [95% CI, 0.90-0.93]) was lower among Hispanics (13.2%) and non-Hispanic blacks (13.6%) compared with non-Hispanic whites (25.8%; adjusted prevalence ratio: 0.63 [0.61-0.66] and 0.70 [0.67-0.72], respectively), and varied by hospital referral region and Census Division (range: 18.6% [East South Central] to 39.1% [West North Central]) and by qualifying event type (range: 7.1% [acute myocardial infarction without procedure] to 55.3% [coronary artery bypass surgery only]). Timely initiation varied by geography and qualifying event type; completion varied by geography. CONCLUSIONS: Only 1 in 4 CR-eligible Medicare beneficiaries participated in CR and marked disparities were observed. Reinforcement of current effective strategies and development of new strategies will be critical to address the noted disparities and achieve the 70% participation goal.

Disparities in the Prevalence of Excess Heart Age Among Women with a Recent Live Birth.

Background: Understanding and addressing cardiovascular disease (CVD) risk has implications for maternal and child health outcomes. Heart age, the modeled age of an individual's cardiovascular system based on risk level, and excess heart age, the difference between a person's heart age and chronological age, are alternative simplified ways to communicate CVD risk. Among women with a recent live birth, we predicted heart age, calculated prevalence of excess heart age (≥5 years), and examined factors associated with excess heart age. Materials and Methods: Data were analyzed in 2017 from 2009 to 2014 Pregnancy Risk Assessment Monitoring System (PRAMS). To calculate heart age we used maternal age, prepregnancy body mass index, systolic blood pressure, smoking status, and diabetic status. Weighted prevalence and prevalence ratios compared the likelihood of excess heart age across racial/ethnic groups by selected factors. Results: Prevalence of excess heart age was higher in non-Hispanic black women (11.8%) than non-Hispanic white women (7.3%, prevalence ratio [PR], 95% confidence interval [CI]: 1.62, 1.49-1.76) and Hispanic women (4.9%, PR, 95% CI: 2.39, 2.10-2.72). Prevalence of excess heart age was highest among women who were without health insurance, obese or overweight, engaged in physical activity less than thrice per week, or were smokers in the prepregnancy period. Among women with less than high school education, non-Hispanic black women had a higher prevalence of excess heart age than Hispanic women (PR, 95% CI: 4.01, 3.15-5.10). Conclusions: Excess heart age may be an important tool for decreasing disparities and encouraging CVD risk reduction among certain groups of women.

National Rates of Nonadherence to Antihypertensive Medications Among Insured Adults With Hypertension, 2015.

Despite the importance of antihypertensive medication therapy for blood pressure control, no single data system provides estimates of medication nonadherence rates across age groups and health insurance plans types. Using multiple administrative datasets and national survey data, we determined health insurance plan-specific and overall weighted national rates of nonadherence to antihypertensive medications among insured hypertensive US adults in 2015. We used 2015 prescription claims data from Medicare Part D and 3 IBM MarketScan databases (Commercial, Medicaid, Medicare Supplemental) to calculate medication nonadherence rates among hypertensive adults aged ≥18 years with public or private health insurance using the proportion of days covered algorithm. These findings, in combination with National Health Interview Survey findings, were used to project national weighted estimates of nonadherence. We included 23.8 million hypertensive adults who filled 265.8 million prescriptions for antihypertensive medications. Nonadherence differed by health insurance plan type (highest for Medicaid members, 55.4%; lowest for Medicare Part D members, 25.2%). The overall weighted national nonadherence rate was 31.0%, with greater nonadherence among women versus men, younger versus older adults (aged 18-34 years, 58.1%; aged 65-74 years, 24.4%), fixed-dose combination medication nonusers (31.2%) versus users (29.4%), and by pharmacy outlet type (retail only, 30.7%; any mail order, 19.8%). In 2015, almost one-third (≈16.3 million) of insured US adults with diagnosed hypertension were considered nonadherent to their antihypertensive medication regimen, and considerable disparities were evident. Public health and healthcare professionals can use available evidence-based interventions to address nonadherence and improve blood pressure control.

Modeling the Health and Budgetary Impacts of a Team-based Hypertension Care Intervention That Includes Pharmacists.

OBJECTIVE: The objective of this study was to assess the potential health and budgetary impacts of implementing a pharmacist-involved team-based hypertension management model in the United States. RESEARCH DESIGN: In 2017, we evaluated a pharmacist-involved team-based care intervention among 3 targeted groups using a microsimulation model designed to estimate cardiovascular event incidence and associated health care spending in a cross-section of individuals representative of the US population: implementing it among patients with: (1) newly diagnosed hypertension; (2) persistently (≥1 year) uncontrolled blood pressure (BP); or (3) treated, yet persistently uncontrolled BP-and report outcomes over 5 and 20 years. We describe the spending thresholds for each intervention strategy to achieve budget neutrality in 5 years from a payer's perspective. RESULTS: Offering this intervention could prevent 22.9-36.8 million person-years of uncontrolled BP and 77,200-230,900 heart attacks and strokes in 5 years (83.8-174.8 million and 393,200-922,900 in 20 years, respectively). Health and economic benefits strongly favored groups 2 and 3. Assuming an intervention cost of $525 per enrollee, the intervention generates 5-year budgetary cost-savings only for Medicare among groups 2 and 3. To achieve budget neutrality in 5 years across all groups, intervention costs per person need to be around $35 for Medicaid, $180 for private insurance, and $335 for Medicare enrollees. CONCLUSIONS: Adopting a pharmacist-involved team-based hypertension model could substantially improve BP control and cardiovascular outcomes in the United States. Net cost-savings among groups 2 and 3 make a compelling case for Medicare, but favorable economics may also be possible for private insurers, particularly if innovations could moderately lower the cost of delivering an effective intervention.

Association Between Medicaid Coverage and Income Status on Health Care Use and Costs Among Hypertensive Adults After Enactment of the Affordable Care Act.

BACKGROUND: Hypertension is highly prevalent among the low-income population in the United States. This study assessed the association between Medicaid coverage and health care service use and costs among hypertensive adults following the enactment of the Patient Protection and Affordable Care Act (ACA), by income status level. METHODS: A nationally representative sample of 2,866 nonpregnant hypertensive individuals aged 18-64 years with income up to 138% of the federal poverty level (FPL) were selected from the 2014 and 2015 Medical Expenditure Panel Survey. Regression analyses were performed to examine the association of Medicaid coverage with outpatient (outpatient visits and prescription medication fills), emergency, and acute health care service use and costs among those potentially eligible for Medicaid by income status-the very low-income (FPL ≤ 100%) and the moderately low-income (100% > FPL ≤ 138%). RESULTS: Among the study population, 70.1% were very low-income and 29.9% were moderately low-income. Full-year Medicaid coverage was higher among the very low-income group (41.0%) compared with those moderately low-income (29.1%). For both income groups, having full-year Medicaid coverage was associated with increased health care service use and higher overall annual medical costs ($13,085 compared with $7,582 without Medicaid); costs were highest among moderately low-income patients ($17,639). CONCLUSION: Low-income individuals with hypertension, who were potentially newly eligible for Medicaid under the ACA may benefit from expanded Medicaid coverage by improving their access to outpatient services that can support chronic disease management. However, to realize decreases in medical expenditures, efforts to decrease their use of emergency and acute care services are likely needed.

The Burden of Cerebrovascular Disease in the United States.

INTRODUCTION: Little is known about trends in the overall combined burden of fatal and nonfatal cerebrovascular disease events in the United States. Our objective was to describe the combined burden by age, sex, and region from 2006 through 2014. METHODS: We used data on adults aged 35 and older from 2006 through 2014 Nationwide Emergency Department Sample, National Inpatient Sample of the Healthcare Cost and Utilization Project, and the National Vital Statistics System. We calculated age-standardized cerebrovascular disease event rates by using the 2010 US Census population. Trends in rates were assessed by calculating the relative percentage change (RPC) between 2006 and 2014, and by using Joinpoint to obtain P values for overall trends. RESULTS: The age-standardized rate increased significantly for total cerebrovascular disease events (primary plus comorbid events) from 1,050 per 100,000 in 2006 to 1,147 per 100,000 in 2014 (P < .05 for trend). Treat-and-release emergency department visits with comorbid cerebrovascular disease events increased significantly, from 114 per 100,000 in 2006 to 213 per 100,000 in 2014 (RPC of 87%, P < .05 for trend). Significant rate increases were identified among adults aged 35 to 64 with an RPC of 19% in primary cerebrovascular disease events, 48% in comorbid cerebrovascular disease events, and 36% in total events. CONCLUSION: Our findings have important implications for the increasing cerebrovascular disease burden among adults aged 35 to 64. Focused prevention strategies should be implemented, especially among young adults who may be unaware of existing modifiable risk factors.

National Burden of Heart Failure Events in the United States, 2006 to 2014.

BACKGROUND: Heart failure (HF)-a serious and costly condition-is increasingly prevalent. We estimated the US burden including emergency department (ED) visits, inpatient hospitalizations and associated costs, and mortality. METHODS AND RESULTS: We analyzed 2006 to 2014 data from the Healthcare Cost and Utilization Project Nationwide Emergency Department Sample, the Healthcare Cost and Utilization Project National (nationwide) Inpatient Sample, and the National Vital Statistics System. International Classification of Disease codes identified HF and comorbidities. Burden was estimated separately for ED visits, hospitalizations, and mortality. In addition, criteria were applied to identify total unique acute events. Rates of primary HF (primary diagnosis or underlying cause of death) and comorbid HF (comorbid diagnosis or contributing cause of death) were calculated, age standardized to the 2010 US population. In 2014, there were an estimated 1 068 412 ED visits, 978 135 hospitalizations, and 83 705 deaths with primary HF. There were 4 071 546 ED visits, 3 370 856 hospitalizations, and 230 963 deaths with comorbid HF. Between 2006 and 2014, the total unique acute event rate for primary HF declined from 536 to 449 per 100 000 (relative percent change of -16%; P for trend, <0.001) but increased for comorbid HF from 1467 to 1689 per 100 000 (relative percentage change, 15%; P for trend, <0.001). HF-related mortality decreased significantly from 2006 to 2009 but did not change meaningfully after 2009. For hospitalizations with primary HF, the estimated mean cost was $11 552 in 2014, totaling an estimated $11 billion. CONCLUSIONS: Given substantial healthcare and mortality burden of HF, rising healthcare costs, and the aging US population, continued improvements in HF prevention, management, and surveillance are important.

Vital Signs: State-Level Variation in Nonfatal and Fatal Cardiovascular Events Targeted for Prevention by Million Hearts 2022.

INTRODUCTION: Despite its preventability, cardiovascular disease remains a leading cause of morbidity, mortality, and health care costs in the United States. This study describes the burden, in 2016, of nonfatal and fatal cardiovascular events targeted for prevention by Million Hearts 2022, a national initiative working to prevent one million cardiovascular events during 2017-2021. METHODS: Emergency department (ED) visits and hospitalizations were identified using Healthcare Cost and Utilization Project databases, and deaths were identified using National Vital Statistics System data. Age-standardized Million Hearts-preventable event rates and hospitalization costs among adults aged ≥18 years in 2016 are described nationally and across states, as data permit. Expected 2017-2021 event totals and hospitalization costs were estimated assuming 2016 values remain unchanged. RESULTS: Nationally, in 2016, 2.2 million hospitalizations (850.9 per 100,000 population) resulting in $32.7 billion in costs, and 415,480 deaths (157.4 per 100,000) occurred. Hospitalization and mortality rates were highest among men (989.6 and 172.3 per 100,000, respectively) and non-Hispanic blacks (211.6 per 100,000, mortality only) and increased with age. However, 805,000 hospitalizations and 75,245 deaths occurred among adults aged 18-64 years. State-level variation occurred in rates of ED visits (from 56.4 [Connecticut] to 274.8 per 100,000 [Kentucky]), hospitalizations (484.0 [Wyoming] to 1670.3 per 100,000 [DC]), and mortality (111.2 [Vermont] to 267.3 per 100,000 [Mississippi]). Approximately 16.3 million events and $173.7 billion in hospitalization costs could occur during 2017-2021 without preventive intervention. CONCLUSIONS AND IMPLICATIONS FOR PUBLIC HEALTH PRACTICE: Million Hearts-preventable events place a considerable health and economic burden on the United States. With coordinated efforts, many of these events could be prevented in every state to achieve the initiative's goal.

Use of Outpatient Rehabilitation Among Adult Stroke Survivors - 20 States and the District of Columbia, 2013, and Four States, 2015.

Stroke is a leading cause of mortality and disability in the United States (1,2). Approximately 800,000 American adults experience a stroke each year (2,3). Currently, approximately 6 million stroke survivors live in the United States (2). Participation in stroke rehabilitation (rehab), which occurs in diverse settings (i.e., in-hospital, postacute care, and outpatient settings), has been determined to reduce stroke recurrence and improve functional outcomes and quality of life (3,4). Despite longstanding national guidelines recommending stroke rehab, it remains underutilized, especially in the outpatient setting. Professional associations and evidence-based guidelines support the increasing stroke rehab use in health systems and are promoted by the public health community (3-6). An analysis of 2005 Behavioral Risk Factor Surveillance System (BRFSS) data revealed that 30.7% of stroke survivors reported participation in outpatient rehab for stroke after hospital discharge in 21 states and the District of Columbia (DC) (7). To update these estimates, 2013 and 2015 BRFSS data were analyzed to assess outpatient rehab use among adult stroke survivors. Overall, outpatient rehab use was 31.2% (20 states and DC) in 2013 and 35.5% (four states) in 2015. Disparities were evident by sex, race, Hispanic origin, and level of education. Focused attention on system-level interventions that ensure participation is needed, especially among disparate populations with lower levels of participation.

Expansion Of Telestroke Services Improves Quality Of Care Provided In Super Rural Areas.

Telestroke is a telemedicine intervention that facilitates communication between stroke centers and lower-resourced facilities to optimize acute stroke management. Using administrative claims data, we assessed trends in telestroke use among fee-for-service Medicare beneficiaries with acute ischemic stroke and the association between providing telestroke services and intravenous tissue plasminogen activator (IV tPA) and mechanical thrombectomy use, mortality, and medical expenditures, by urban versus rural county of residence in the period 2008-15. The proportion of ischemic stroke cases receiving telestroke increased from 0.4 to 3.8 per 1,000 cases, with usage highest among younger, male, non-Hispanic white, and patients in rural or super rural areas (super rural is the bottom quartile of rural areas. Compared with patients receiving usual care, those receiving telestroke had greater IV tPA and mechanical thrombectomy use regardless of county type, while those in super rural counties had lower thirty-day all-cause mortality. Despite increased telestroke use, rural patients remained less likely than urban patients to receive IV tPA. The findings suggest that telestroke service expansion efforts have increased, especially in rural and super rural counties, and have improved outcomes.

Prevalence and Medical Costs of Chronic Diseases Among Adult Medicaid Beneficiaries.

INTRODUCTION: This review summarizes the current literature for the prevalence and medical costs of noncommunicable chronic diseases among adult Medicaid beneficiaries to inform future program design. METHODS: The databases MEDLINE and CINAHL were searched in August 2016 using keywords, including Medicaid, health status, and healthcare cost, to identify original studies that were published during 2000-2016, examined Medicaid as an independent population group, examined prevalence or medical costs of chronic conditions, and included adults within the age group 18-64 years. The review and data extraction was conducted in Fall 2016-Spring 2017. Disease-related costs (costs specifically to treat the disease) and total costs (all-cause medical costs for a patient with the disease) are presented separately. RESULTS: Among the 29 studies selected, prevalence estimates for enrollees aged 18-64 years were 8.8%-11.8% for heart disease, 17.2%-27.4% for hypertension, 16.8%-23.2% for hyperlipidemia, 7.5%-12.7% for diabetes, 9.5% for cancer, 7.8%-19.3% for asthma, 5.0%-22.3% for depression, and 55.7%-62.1% for one or more chronic conditions. Estimated annual per patient disease-related costs (2015 U.S. dollars) were $3,219-$4,674 for diabetes, $3,968-$6,491 for chronic obstructive pulmonary disease, and $989-$3,069 for asthma. Estimated hypertension-related costs were $687, but total costs per hypertensive beneficiary ranged much higher. Estimated total annual healthcare costs were $29,271-$51,937 per beneficiary with heart failure and $11,446-$20,585 per beneficiary with schizophrenia. Costs among beneficiaries with cancer were $29,384-$46,194 for the 6 months following diagnosis. CONCLUSIONS: These findings could help inform the evaluation of interventions to prevent and manage noncommunicable chronic diseases and their potential to control costs among the vulnerable Medicaid population.

Emergency Department, Hospital Inpatient, and Mortality Burden of Atrial Fibrillation in the United States, 2006 to 2014.

The prevalence of atrial fibrillation (AF) is increasing in the United States as the population ages, but national surveillance is lacking. This cross-sectional study (2006 to 2014) analyzed data from the Healthcare Cost and Utilization Project's Nationwide Emergency Department Sample, the National (Nationwide) Inpatient Sample, and the National Vital Statistics System. Event totals were estimated independently for emergency department (ED) visits, hospitalizations, and mortality, and then collectively after applying criteria to identify mutually exclusive events. Rates were calculated for AF as primary diagnosis or underlying cause of death (primary AF), as well as secondary diagnosis or contributing cause of death (co-morbid AF), and standardized by age to the 2010 US population. From 2006 to 2014, event rates increased for primary AF (249 to 268 per 100,000) and co-morbid AF (1,473 to 1,835 per 100,000). In 2014, an estimated 599,790 ED visits, 453,060 hospitalizations, and 21,712 deaths listed AF as primary. A total of 684,470 mutually exclusive primary AF and 4,695,997 mutually exclusive co-morbid AF events occurred. Among ED visits and hospitalizations with primary AF, the most common secondary diagnoses were hypertension, heart failure, ischemic heart disease, and diabetes. The mean cost per hospitalization with primary AF was $8,819. Mean costs were higher for those with co-morbid AF versus those without co-morbid AF among hospitalizations with a primary diagnosis of ischemic heart disease, heart failure, stroke, hypertension, or diabetes (all p ≤0.01). In conclusion, with the substantial health and economic impact of AF and an aging US population, improved diagnosis, prevention, management, and surveillance of AF are increasingly important.
