BackgroundPatients hospitalized with heart failure (HF) and diabetes mellitus (DM) are at risk for worsening clinical status. Little is known about the frequency of therapeutic changes during hospitalization. We characterized the use of medical therapies before, during and after hospitalization in patients with HF and DM.MethodsWe identified Medicare beneficiaries in Get With The Guidelines-Heart Failure (GWTG-HF) hospitalized between July 2014 and September 2019 with Part D prescription coverage. We evaluated trends in the use of 7 classes of antihyperglycemic therapies (metformin, sulfonylureas, GLP-1RA, SGLT2-inhibitors, DPP-4 inhibitors, thiazolidinediones, and insulins) and 4 classes of HF therapies (evidence-based β-blockers, ACEi or ARB, MRA, and ARNI).

Cardiovascular disease (CVD) is a major source of morbidity, mortality, and costs worldwide Approximately 523 million people worldwide were living with CVD in 2019, and in the same year CVD was associated with nearly 19 million deaths. 1 Costs in the USA alone were estimated at over US $200 billion in 2018. 2 The burden on the individual patient is similarly great—not only from direct healthcare spending, but also from hospitalizations, readmissions, decreased quality of life, and premature mortality. Moreover, both globally and in the USA in particular, this burden disproportionately impacts low-income individuals and people identifying as Black or Hispanic compared with patients identifying as White. 3In this issue of the European Heart Journal, a new study by Henry et al. analysed the National Inpatient Sample (NIS) for US hospitals to identify trends in cardiovascular hospitalizations and in-hospital mortality …

BackgroundSocioeconomic inequities in access to heart transplantation are well-documented, and may in part relate to insurance coverage. During the COVID pandemic, the federal government declared a Public Health Emergency (PHE), effective January 27, 2020, which prevented states from disenrolling people from Medicaid during this critical time period. We sought to determine whether the growth in Medicaid enrollment as a consequence of the PHE was associated with changes in the insurance composition of the heart transplant waiting list, the main insurance-dependent step in the transplant process.MethodsUsing the UNOS thoracic dataset, we analyzed weekly counts of adults (age> 17) added to the heart transplant waitlist on between January 1, 2018 and December 31, 2021 by primary payer, accounting for holiday effects and the acute dropoff in listing during the height of COVID-19 (March 14-June …

When President Obama came to office in 2008, his administration faced compounding health system challenges. Nearly 45 million Americans lacked health insurance coverage. Concerns that private plans were overtly prioritizing profits rather than patients had intensified. National health care costs had risen to 17% of the gross domestic product. At the same time, health outcomes in the United States were worse than comparable countries. In 2010, President Obama signed the Affordable Care Act (ACA) into law, which had 3 areas of focus: expanding coverage through public and private payers, reforming health insurance markets to be more patient-friendly, and improving quality of care and reducing spending through value-based payment programs.

Targeted temperature management (TTM) is recommended for patients who do not respond after return of spontaneous circulation after cardiac arrest. However, the degree to which patients with cardiac arrest have access to this therapy on a national level is not known. Understanding hospital- and patient-level factors associated with receipt of TTM could inform interventions to improve access to this treatment among appropriate patients. Therefore, we performed a retrospective analysis using National Inpatient Sample data from 2016 to 2019.

Medicare implemented Bundled Payments for Care Improvement (BPCI) Model 3 in 2013, in which participating skilled nursing facilities (SNFs) were accountable for episode costs. We performed comparative interrupted time series analyses to evaluate associations between SNF BPCI participation and nurse staffing levels, using Medicare claims, resident assessments, and facility-level and market-level files of 2010–2017. For persistent-participating SNFs, BPCI was associated with improved certified nursing assistant (CNA) staffing levels (differential change = .03 hours, p = .025). However, BPCI was not related to changes in registered nurse (RN) and all licensed nurse hours, and nurse skill mix. Among drop-out SNFs, BPCI was associated with increased RN staffing levels (differential change = .02 hours, p = .009), leading to a higher nurse skill ratio (0.51 percentage points, p = .016) than control SNFs.

It seems unlikely that a significant proportion of individuals, who paid for a long-acting levonorgestrel IUS and had the device inserted, would deliberately pursue removal within the first year of use with the intent of conceiving. In fact, a study cited by Jugl and Winterstein concluded that the main reason for levonorgestrel IUS discontinuation within the first year of insertion is adverse effects from the IUS, such as pain and abnormal bleeding, not the desire to conceive. 2 Individuals choosing to remove a recently inserted IUS due to adverse effects would likely switch to another hormonal contraceptive method, which was accounted for in our Research Letter. 1 Jugl and Winterstein request an analysis on all pregnancy outcomes. Using the same cohort and the same statistical model to calculate the incidence of conceiving (instead of incidence of ectopic pregnancy) within the first year of a filled levonorgestrel IUS …

BACKGROUND Bundled Payments for Care Improvement–Advanced (BPCI-A) is a Medicare initiative that aims to incentivize reductions in spending for episodes of care that start with a hospitalization and end 90 days after discharge. Cardiovascular disease, an important driver of Medicare spending, is one of the areas of focus BPCI-A. It is unknown whether BPCI-A is associated with spending reductions or quality improvements for the 3 cardiovascular medical events or 5 cardiovascular procedures in the model. METHODS In this retrospective cohort study, we conducted difference-in-differences analyses using Medicare claims for patients discharged between January 1, 2017, and September 30, 2019, to assess differences between BPCI-A hospitals and matched nonparticipating control hospitals.

Over the past 2 decades, the US government has steadily shifted care for Medicare beneficiaries into value-based payment models. Central to their success is the ability to measure and pay fairly for performance on quality measures, including clinical outcome measures. While there is broad consensus that outcome measures, such as age and comorbidities, should be adjusted for clinical risk, there is considerable controversy regarding whether they should be adjusted for social risk. Proponents of social risk adjustment argue that failure to account for social factors that are independently associated with health outcomes leads to fundamentally inaccurate characterization of clinicians’ performance and inappropriately penalizes those caring for historically marginalized patients. 1 Opponents of social risk adjustment argue that it obscures disparities, reduces incentives to invest in efforts that improve equity, and …

Heart failure (HF) is a common and highly morbid condition that impacts more than 65 million patients worldwide, including more than 6 million patients in the United States, and it leads to more than $30 billion in annual health care spending. 1 One of the most important tools we have as clinicians to improve outcomes in this disease is the use of highly effective guideline-directed medical therapy (GDMT) using clinical trial–proven medications. However, several prior studies have shown that use of GDMT is suboptimal; the CHAMP-HF (Change the Management of Patients with Heart Failure) registry showed that< 1% of patients at 12 months of followup were on target doses of all 3 medication classes. 2 One facet of GDMT delivery that has been less well understood is where and when these medications should be initiated and titrated.

Introduction: Cardiac rehabilitation (CR) improves outcomes after acute myocardial infarction (AMI). The Bundled Payments for Care Improvement Advanced (BPCI-A) program holds participating hospitals accountable for all costs incurred within 90 days of discharge. There is concern that this financial incentive will lead participants to cut back on high-value care, including CR, in order to meet cost targets. We examined whether patients discharged from BPCI-A participating hospitals after an AMI had lower CR utilization compared to non-participating hospitals. Methods: We included patients from a 100% sample of fee-for-service Medicare beneficiaries discharged home after a hospitalization for AMI during a baseline period (January 1, 2016 to December 31, 2017) or an intervention period (October 1, 2018 to September 30, 2019).

Methods and Results We used emergency department and inpatient data from a 12‐hospital health system to examine changes in volume, patient age and comorbidities, treatment (right‐ and left‐heart catheterization), and outcomes for patients with acute myocardial infarction (AMI) and heart failure (HF) during the COVID‐19 pandemic compared with pre‐COVID‐19 (2018 and 2019), controlling for seasonal variation. We analyzed 27 427 emergency department visits or hospitalizations. Patient volume decreased during COVID‐19 for both HF and AMI, but age, race, sex, and medical comorbidities were similar before and during COVID‐19 for both …

The Centers for Medicare & Medicaid Services (CMS) is moving increasingly toward alternative payment models that incentivize high-quality, low-cost care. Bundled payments, for example, now cover medical, procedural, and therapeutic episodes, from a broad range of medical and surgical conditions in Bundled Payments for Care Improvement Advanced (BPCI-A); to hip and knee replacements in the Comprehensive Care for Joint Replacement Model (CJR); to chemotherapy administration in the Oncology Care Model (OCM). Bundled payments encourage cost efficiency by setting a total spending benchmark for all services associated with a clinical “episode.” In the full riskbearing phase of these and other similar programs, if model participants reduce average costs below their benchmark, CMS rewards them with a financial bonus; if their costs exceed the benchmark, they owe CMS a penalty payment.Many feel …

Background Black adults experience a disproportionately higher burden of cardiovascular risk factors and disease in comparison with White adults in the United States. Less is known about how sex-based disparities in cardiovascular mortality between these groups have changed on a national scale over the past 20 years, particularly across geographic determinants of health and residential racial segregation. Methods We used CDC WONDER (Centers for Disease Control and Prevention’s Wide-Ranging Online Data for Epidemiologic Research) to identify Black and White adults age ≥25 years in the United States from 1999 to 2019. We calculated annual age-adjusted cardiovascular mortality rates (per 100 000) for Black and White women and men, as well as absolute rate differences and rate ratios to compare the mortality gap between these groups.

Introduction: The gold standard risk prediction tool for atherosclerotic cardiovascular disease (ASCVD), the Pooled Cohort Equations (PCE) underestimates risk among the socially disadvantaged, yet social determinants of health are absent from the PCE. This may be contributing to racial inequities in CVD since due to systemic and structural racism, socioeconomic disadvantage is disproportionately concentrated in African American (AA) communities. This analysis aimed to determine whether SDOH variables were important for the prediction of 10-year ASCVD risk in a large cohort of AA and to test whether the addition of these variables improved PCE model performance. Methods: Retrospective observational study of 3,470 Jackson Heart Study (JHS) participants aged 40-79 years old without prior ASCVD at baseline study visit. 10-year ASCVD event was defined as stroke, MI, or death from MI.

Medicare’s Bundled Payments for Care Improvement Advanced Model (BPCI-A) is a voluntary Alternative Payment Model in which participating hospitals are held accountable for ninety-day episodes of care. To meet spending targets, hospitals must either decrease utilization or attract a less sick patient population; this could lead to the elimination of necessary care or avoidance of patients with medical or social vulnerability. We used publicly available data on BPCI-A participation, along with Medicare claims from the period 2017–19, to examine patient selection, changes in Medicare payment, and key clinical outcomes among three groups: patients with frailty, patients with multimorbidity, and patients with dual enrollment (both Medicare and Medicaid).

Introduction: In October 2018, the heart allocation policy for adult heart transplant (OHTx) in the United States was changed, with the goal of reducing waitlist mortality and providing broader sharing of donor organs within the United States. The aim of this study was to assess the effect of this policy change on access to OHTx vs LVAD, overall and among key sociodemographic subgroups, in the US from 2016 to 2019. Hypothesis: We hypothesized that the UNOS heart allocation policy would increase OHTx volume overall as well as use of temporary mechanical circulatory support. Methods: We identified all patients receiving OHTx or LVAD between 2016-2019 using the National Inpatient Sample. Controlling for medical comorbidities, trends over time, and within hospital-year effects, we fit a dynamic logistic regression model to evaluate patient and hospital factors associated with receiving OHTx vs LVAD pre- versus …

Health care disparities occur across a broad range of dimensions but are often viewed through the lens of race, ethnicity, sex, and socioeconomic status. Equally important but less well recognized are disparities related to geographic location. Across many health conditions, including acute cardiovascular diseases, there is a health disadvantage in rural areas compared with urban and suburban locations. 1 In the US, cardiovascular mortality rates are higher in rural communities compared with urban areas owing to a greater burden of traditional and socioeconomic risk factors, poorer access to health care, and lower quality of care. 2 ST-segment elevation myocardial infarction (STEMI), one of the most common cardiac emergencies, clearly illustrates this dilemma. 3 Like other emergencies, STEMI outcomes depend critically on early recognition and timely treatment, which in most rural hospitals involves primary …

In fiscal year 2019 the program was changed to account for the association between social risk and high readmission rates. The new approach stratifies hospitals into five groups by hospitals’ proportion of patients dually enrolled in Medicare and Medicaid, and it evaluates performance within each stratum instead of within the national cohort. Its impact on hospitals caring for vulnerable populations has not been studied. We calculated the change in average annual penalty percentage, before and after stratification, for safety-net hospitals, rural hospitals, and hospitals caring for a high share of Black and Hispanic or Latino patients.
