Rationale, Design, and Patient Characteristics of a Cluster-Randomized Pragmatic Trial to Improve Mineralocorticoid Antagonist Use.

BACKGROUND: Despite robust evidence and strong guideline recommendations supporting use of mineralocorticoid receptor antagonists (MRAs) to improve outcomes in patients with heart failure with reduced ejection fraction (HFrEF), these medications remain underused in clinical practice. OBJECTIVES: The goal is to determine if providing a tailored best practice alert (BPA) to outpatient providers suggesting guideline-recommended MRAs or information about available hyperkalemia treatment, if present, for patients with HFrEF will increase short-term MRA prescriptions. METHODS: PROMPT-MRA (Pragmatic Trial of Messaging to Providers About Treatment With Mineralocorticoid Receptor Antagonists) is a pragmatic, cluster-randomized, controlled study. A total of 119 providers were randomized to receive a BPA or usual care. During an outpatient visit with participating providers, the BPA displayed recent laboratory test values and ejection fraction. The alert suggested guideline-recommended MRAs for eligible patients with a serum potassium of <5.0 mEq/L or novel potassium binders for those with a serum potassium of ≥5.0 mEq/L, each linked to an order set containing the corresponding medication and laboratory monitoring. RESULTS: PROMPT-MRA completed enrollment with 1,210 patients. The primary outcome of PROMPT-MRA is to determine if a tailored BPA for outpatients with HFrEF will lead to higher MRA prescriptions 6 months following randomization compared with usual care. Secondary outcomes included incidence of hyperkalemia, use of novel potassium binders, heart failure hospitalizations, and mortality. CONCLUSIONS: If effective, the BPA can be scaled to improve population health outcomes with increased MRA prescribing among eligible patients with HFrEF, with or without a history of hyperkalemia.

Defining a path toward improved heart failure care.

Defining a path toward improved heart failure (HF) care is essential, as there is a clear need to improve HF treatment quality, outcomes, and value. This article reviews potential strategies to help improve the quality of HF clinical care and decrease costs. To start, HF phenotyping may be useful in guiding patient treatment, as some phenotypes are associated with higher hospitalization costs and longer length of stay. Identifying and addressing social determinants of health that may be barriers to optimal health may improve management of HF and help to prevent disease progression. In addition, patient-reported outcomes can be useful for evaluating the effectiveness of treatment regimens and assessing which treatments lead to a genuine improvement in quality of life (QOL). Recent innovations in payment reform have seen the implementation of value-based payment (VBP) models over the traditional fee-for-service (FFS) models. FFS models can lead to low-quality care focused on treating illness instead of supporting wellness initiatives. By contrast, VBP models aim to decrease excessive health care costs, thereby increasing incentives to hospitals that deliver high-quality patient care. Further, novel care delivery approaches, such as hospital-at-home and other digital tools, can provide patients with lower-cost care and are associated with improved QOL, including reductions in hospital readmission.

The use of sodium-glucose cotransporter 2 inhibitors in heart failure with reduced or preserved ejection fraction: new guidelines hot off the press and directly into guidelines!

It is well known that the prevalence of heart failure (HF) is high and continues to grow. Sodium-glucose cotransporter 2 (SGLT2) inhibitors, although initially developed as a therapy for type 2 diabetes, have been found to be beneficial in patients with HF, regardless of diabetic status. Given the clinical benefit demonstrated in recent large randomized clinical trials in those with HF, they have been rapidly incorporated into clinical practice and adopted by the national guidelines hot off the press. SGLT2 inhibitors are now recommended for patients with symptomatic HF, with any ejection fraction. These medications are generally very well tolerated by patients, and adverse effects include genital and soft tissue infections, euglycemic ketoacidosis, and volume depletion. SGLT2 inhibitors have now become a pillar of the pharmacologic treatment of HF, thus providers should be familiar with their use for not only those with type 2 diabetes, but also those with HF.

Thirty-Day and 90-Day Episode of Care Spending Following Heart Failure Hospitalization Among Medicare Beneficiaries.

BACKGROUND: Despite growing interest in value-based models, utilization patterns and costs for heart failure (HF) admissions are not well understood. We sought to characterize Medicare spending for patients with HF for 30- and 90-day episodes of care (which include an index hospitalization and 30 or 90 days following discharge) and to describe the patterns of post-acute care spending. METHODS: Using Medicare fee-for-service administrative claims data from 2016 to 2018, we performed a retrospective analysis of patients discharged after hospitalization with primary discharge diagnoses of systolic HF, diastolic HF, hypertensive heart disease (HHD) with HF, and HHD with HF and chronic kidney disease. We analyzed coding patterns across these groups over time, median 30- and 90-day payments, and costs allocated to index hospitalization and postacute care. RESULTS: The study included 935 962 patients discharged following hospitalization for HF (systolic HF: 178 603; diastolic HF: 165 156; HHD with HF: 226 929; HHD with HF and chronic kidney disease: 365 274). The proportion of HHD codes increased from 26% of HF hospitalizations in 2016 to 91% in 2018. There was substantial spending on 30-day (median $13 330, interquartile range $9912-$22 489) and 90-day episodes (median $21 658, interquartile range $12 423-$37 630) for HF with significant variation, such that the third quartile of patients incurred costs 3 times the amount of the first quartile. Across all codes, the index hospitalization accounted for ≈70% of 30-day and 45% of 90-day spending. Sixty-one percent of postacute care spending occurred 31 to 90 days following discharge, with readmissions and observation stays (36%) and skilled nursing facilities (27%) comprising the largest categories. CONCLUSIONS: This patient episode-level analysis of contemporary Medicare beneficiaries is the first to examine 90-day spending, which will become an increasingly important pasyment benchmark with the expansion of the Medicare Bundled Payments for Care Improvement Program. Further investigation into the drivers of costs will be essential to provide high-value HF care.

Trends in Heart Failure Hospitalizations in the US from 2008 to 2018.

BACKGROUND: Heart failure (HF) is a major driver of health care costs in the United States and is increasing in prevalence. There is a paucity of contemporary data examining trends among hospitalizations for HF that specifically compare HF with reduced or preserved ejection fraction (HFrEF or HFpEF, respectively). METHODS AND RESULTS: Using the National Inpatient Sample, we identified 11,692,995 hospitalizations due to HF. Hospitalizations increased from 1,060,540 in 2008 to 1,270,360 in 2018. Over time, the median age of patients hospitalized because of HF decreased from 76.0 to 73.0 years (P < 0.001). There were increases in the proportions of Black patients (18.4% in 2008 to 21.2% in 2018) and of Hispanic patients (7.1% in 2008 to 9.0% in 2018; P < 0.001, all). Over the study period, we saw an increase in comorbid diabetes, sleep apnea and obesity (P < 0.001, all) in the entire cohort with HF as well as in the HFrEF and HFpEF subgroups. Persons admitted because of HFpEF were more likely to be white and older compared to admissions because of HFrEF and also had lower costs. Inpatient mortality decreased from 2008 to 2018 for overall HF (3.3% to 2.6%) and HFpEF (2.4% to 2.1%; P < 0.001, all) but was stable for HFrEF (2.8%, both years). Hospital costs, adjusted for inflation, decreased in all 3 groups across the study period, whereas length of stay was relatively stable over time for all groups. CONCLUSIONS: The volume of patients hospitalized due to HF has increased over time and across subgroups of ejection fraction. The demographics of HF, HFrEF and HFpEF have become more diverse over time, and hospital inpatient costs have decreased, regardless of HF type. Inpatient mortality rates improved for overall HF and HFpEF admissions but remained stable for HFrEF admissions.

Brief report: Cannabis and opioid use disorder among heart failure admissions, 2008-2018.

BACKGROUND: In the United States, both cannabis use disorder (CUD) and opioid use disorder (OUD) have increased in prevalence. The prevalence, demographics, and costs of CUD and OUD are not well known in heart failure (HF) admissions. This study aimed to use a national database to examine the prevalence, demographics, and costs associated with CUD and OUD in HF. METHODS: This study used the National Inpatient Sample from 2008 to 2018 to identify all primary HF admissions with and without the co-diagnosis of OUD or CUD using International Classification for Diagnosis, diagnosis codes. Demographics, costs, and trends were examined. RESULTS: Between 2008 and 2018, we identified 11,692,995 admissions for HF of which 84,796 (0.8%) had a co-diagnosis of CUD only, and 67,137 (0.6%) had a co-diagnosis of OUD only. The proportion of HF admissions with CUD significantly increased from 0.3% in 2008 to 1.3% in 2018 (p<0.001). The proportion of HF admissions with OUD significantly increased from 0.2% in 2008 to 1.1% in 2018 (p<0.001). Patients admitted with HF and either CUD or OUD were younger, more likely to be Black, and from lower socioeconomic backgrounds (p<0.001, all). HF admissions with OUD or CUD had higher median costs compared to HF admissions without associated substance abuse diagnoses ($8,611 vs. $8,337 for CUD HF and $10,019 vs. $8,337 for OUD HF, p<0.001 for both). CONCLUSIONS: Among discharge records for HF, CUD and OUD are increasing in prevalence, significantly affect underserved populations and are associated with higher costs of stay. Future research is essential to better delineate the cause of these increased costs and create interventions, particularly in underserved populations.

Comparison of Transcatheter and Open Mitral Valve Repair Among Patients With Mitral Regurgitation.

In 2013, the Food and Drug Administration approved the first transcatheter mitral valve repair (TMVr) device for degenerative mitral regurgitation for patients at prohibitive surgical risk. To better understand contemporary utilization trends and outcomes, we reviewed hospitalizations, identified using International Classification of Diseases, Ninth Revision and International Classification of Diseases, Tenth Revision codes, in which the patient underwent TMVr or mitral valve repair (MVr) with a diagnosis of mitral regurgitation, without stenosis, from the National (Nationwide) Inpatient Sample from 2014 to 2017. We included 10,020 hospitalizations in which the patient underwent TMVr and 5845 in which the patient underwent MVr and assessed trends in demographic characteristics, patient comorbidities, total hospital charges, and outcomes. Transcatheter mitral valve repair experienced exponential growth, increasing from 150 to 5115 over the study period (P<.001 for trend), whereas MVr grew to a lesser degree. The median length of stay for TMVr decreased from 4 to 2 days; mortality declined from 3.3% to 1.6% (P<.001 for both). Both TMVr and MVr rates of discharge home increased over the study period. Total charges for TMVr increased from $149,582 to $178,109, whereas those for MVr increased to a lesser degree, from $149,426 to $157,146 (P<.001 for both). Discharge disposition, length of stay, and in-hospital mortality all exhibited favorable trends for both procedures. Caution must be exercised in direct comparisons between procedures as they target somewhat different populations. With expanded indications for TMVr, we anticipate further increases in procedural volume, although the effect on MVr remains unclear.

Outcomes in patients with anthracycline-induced cardiomyopathy undergoing left ventricular assist devices implantation.

AIMS: Improved cancer survivorship has led to a higher number of anthracycline-induced cardiomyopathy patients with end-stage heart failure. We hypothesize that outcomes following continuous-flow LVAD (CF-LVAD) implantation in those with anthracycline-induced cardiomyopathy are comparable with other aetiologies of cardiomyopathy. METHODS AND RESULTS: Using the Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS) from 2008 to 2017, we identified patients with anthracycline-induced cardiomyopathy who received a CF-LVAD and compared them with those with idiopathic dilated (IDM) and ischaemic cardiomyopathies (ICM). Mortality was studied using the Cox proportional hazards model. Other adverse events were evaluated using competing risk models. Overall, 248 anthracycline-induced cardiomyopathy patients underwent CF-LVAD implantation, with a median survival of 48 months, an improvement compared with those before 2012 [adjusted hazards ratio (aHR): 0.53; confidence interval (CI): 0.33-0.86]. At 12 months, 85.1% of anthracycline-induced cardiomyopathy, 86.0% of IDM, and 80.2% of ICM patients were alive (anthracycline-induced cardiomyopathy vs. IDM: aHR: 1.12; CI: 0.88-1.43 and anthracycline-induced cardiomyopathy vs. ICM: aHR: 0.98; CI: 0.76-1.28). Anthracycline-induced cardiomyopathy patients had a higher major bleeding risk compared with IDM patients (aHR: 1.23; CI: 1.01-1.50), and a lower risk of stroke and prolonged respiratory support compared to ICM patients (aHR: 0.31 and 0.67 respectively; both P < 0.05). There was no difference in the risk of major infection, acute kidney injury, and venous thromboembolism. CONCLUSIONS: After receiving a CF-LVAD, survival in patients with anthracycline-induced cardiomyopathy is similar to those with ICM or IDM. Further research into differential secondary endpoints-related disparities is warranted.

National Trends in the Burden of Atrial Fibrillation During Hospital Admissions for Heart Failure.

Background Heart failure (HF) and atrial fibrillation (AF) frequently coexist and may be associated with worse HF outcomes, but there is limited contemporary evidence describing their combined prevalence. We examined current trends in AF among hospitalizations for HF with preserved (HFpEF) ejection fraction or HF with reduced ejection fraction (HFrEF) in the United States, including outcomes and costs. Methods and Results Using the National Inpatient Sample, we identified 10 392 189 hospitalizations for HF between 2008 and 2017, including 4 250 698 with comorbid AF (40.9%). HF hospitalizations with AF involved patients who were older (average age, 76.9 versus 68.8 years) and more likely White individuals (77.8% versus 59.1%; P<0.001 for both). HF with preserved ejection fraction hospitalizations had more comorbid AF than HF with reduced ejection fraction (44.9% versus 40.8%). Over time, the proportion of comorbid AF increased from 35.4% in 2008 to 45.4% in 2017, and patients were younger, more commonly men, and Black or Hispanic individuals. Comorbid hypertension, diabetes mellitus, and vascular disease all increased over time. HF hospitalizations with AF had higher in-hospital mortality than those without AF (3.6% versus 2.6%); mortality decreased over time for all HF (from 3.6% to 3.4%) but increased for HF with reduced ejection fraction (from 3.0% to 3.7%; P<0.001 for all). Median hospital charges were higher for HF admissions with AF and increased 40% over time (from $22 204 to $31 145; P<0.001). Conclusions AF is increasingly common among hospitalizations for HF and is associated with higher costs and in-hospital mortality. Over time, patients with HF and AF were younger, less likely to be White individuals, and had more comorbidities; in-hospital mortality decreased. Future research will need to address unique aspects of changing patient demographics and rising costs.
