RESUMEN

Importance: A composite score for guideline-directed medical therapy (GDMT) for patients with heart failure (HF) is associated with increased survival. Whether hospital performance according to a GDMT score is associated with a broader array of clinical outcomes at lower costs is unknown. Objectives: To evaluate hospital variability in GDMT score at discharge, 90-day risk-standardized clinical outcomes and costs, and associations between hospital GDMT score and clinical outcomes and costs. Design, Setting, and Participants: This was a retrospective cohort study conducted from January 2015 to September 2019. Included for analysis were patients hospitalized for HF with reduced ejection fraction (HFrEF) in the Get With the Guidelines-Heart Failure Registry, a national hospital-based quality improvement registry. Study data were analyzed from July 2022 to April 2023. Exposures: GDMT score at discharge. Main Outcomes and Measures: Hospital variability in GDMT score, a weighted index from 0 to 1 of GDMT prescribed divided by the number of medications eligible, at discharge was evaluated using a generalized linear mixed model using the hospital as a random effect and quantified with the adjusted median odds ratio (AMOR). Parallel analyses centering on 90-day mortality, HF rehospitalization, mortality or HF rehospitalization, home time, and costs were performed. Costs were assessed from the perspective of the Centers of Medicare & Medicaid Services. Associations between hospital GDMT score and clinical outcomes and costs were evaluated using Spearman coefficients. Results: Among 41 161 patients (median [IQR] age, 78 [71-85] years; 25 546 male [62.1%]) across 360 hospitals, there was significant hospital variability in GDMT score at discharge (AMOR, 1.23; 95% CI, 1.21-1.26), clinical outcomes (mortality AMOR, 1.17; 95% CI, 1.14-1.24; HF rehospitalization AMOR, 1.22; 95% CI, 1.18-1.27; mortality or HF rehospitalization AMOR, 1.21; 95% CI, 1.18-1.26; home time AMOR, 1.07; 95% CI, 1.06-1.10) and costs (AMOR, 1.23; 95% CI, 1.21-1.26). Higher hospital GDMT score was associated with lower hospital mortality (Spearman ρ, -0.22; 95% CI, -0.32 to -0.12; P < .001), lower mortality or HF rehospitalization (Spearman ρ, -0.17; 95% CI, -0.26 to -0.06; P = .002), more home time (Spearman ρ, 0.14; 95% CI, 0.03-0.24; P = .01), and lower cost (Spearman ρ, -0.11; 95% CI, -0.21 to 0; P = .047) but not with HF rehospitalization (Spearman ρ, -0.10; 95% CI, -0.20 to 0; P = .06). Conclusions and Relevance: Results of this cohort study reveal that hospital variability in GDMT score, clinical outcomes, and costs was significant. Higher GDMT score at discharge was associated with lower mortality, lower mortality or hospitalization, more home time, and lower cost. Efforts to increase health care value should include GDMT optimization.

RESUMEN

BACKGROUND: Few study authors examined factors influencing health-related quality of life (HRQOL) early after left ventricular assist device (LVAD) implantation. OBJECTIVE: The purpose of this study was to determine whether 5 novel self-report measures and other variables were significantly associated with overall HRQOL at 3 months after LVAD surgery. METHODS: Patients were recruited between October 26, 2016, and February 29, 2020, from 12 US sites. Data were collected before LVAD implantation and at 3 months post LVAD implantation. Overall HRQOL measures included the Kansas City Cardiomyopathy Questionnaire-12 (KCCQ-12) overall summary score (OSS) and EuroQol 5-dimension- 3L visual analog scale. Potential factors associated with overall HRQOL included 5 novel self-report measures (Satisfaction with Treatment, Being Bothered by VAD Self-care and Limitations, VAD Team Communication, Self-efficacy regarding VAD Self-care, and Stigma), and demographic and clinical characteristics. Statistics included regression analyses. RESULTS: Of enrollees, 242 completed self-report measures at baseline, and 142 completed measures 3 months postoperatively. Patients were 55 ± 13 years old, with 21% female, 24% non-White, 39% high school or lower educated, and 47% destination therapy. Using the KCCQ-12 OSS, higher Satisfaction with Treatment was associated with a higher KCCQ-12 OSS; Being Bothered by VAD Self-care and Limitations, high school or lower education, chest incision pain, cardiac dysrhythmias within 3 postoperative months, and peripheral edema were associated with a worse KCCQ-12 OSS (R2 = 0.524). Factors associated with a worse 3-month EuroQol 5-dimension-3L visual analog scale were female sex, adverse events within 3 months post implantation (cardiac dysrhythmias, bleeding, and venous thrombosis), and chest incision pain (R2 = 0.229). No factors were associated with a higher EuroQol 5-dimension-3L visual analog scale score at 3 months. CONCLUSIONS: Two novel measures, demographics, postimplantation adverse events, and symptoms were associated with post-LVAD KCCQ-12 OSS early after surgery.

RESUMEN

Treatment of heart failure with reduced ejection fraction (HFrEF) has benefitted from a proliferation of new medications and devices. These treatments carry important clinical benefits, but also come with costs relevant to payers, providers, and patients. Patient out-of-pocket costs have been implicated in the avoidance of medical care, nonadherence to medications, and the exacerbation of health care disparities. In the absence of major health care policy and payment redesign, high-quality HFrEF care delivery requires transparent integration of cost considerations into system design, patient-clinician interactions, and medical decision making.

RESUMEN

OBJECTIVES: To elicit perspectives from specialist palliative care (SPC) and cardiology clinicians concerning the necessary components, delivery characteristics and implementation strategies of successful ambulatory SPC for people with heart failure (HF). BACKGROUND: Palliative care is a recommended component of guideline-directed care for people with HF. However, optimal strategies to implement SPC within ambulatory settings are unknown. METHODS: We conducted a qualitative descriptive study composed of semistructured interviews with SPC and cardiology clinicians at Veterans Affairs Medical Centers (VAMCs) with the highest number of ambulatory SPC consultations within the VA system among people with HF between 2021 and 2022. Clinicians were asked how they provided ambulatory SPC and what they felt were the necessary components, delivery characteristics and implementation strategies of care delivery. Interviews were analyzed using directed content analysis. RESULTS: We interviewed 14 SPC clinicians and 9 cardiology clinicians at 7 national VAMCs; 43% were physicians, and 48% were advanced-practice registered nurses/physician associates. Essential components of ambulatory SPC encompassed discussion of goals of care (eg, prognosis, advance directives) and connecting patients/caregivers to resources (eg, home care). Preferred delivery characteristics included integrated (ie, embedded) approaches to SPC delivery, standardized patient selection and referral procedures, and formalized procedures for handoffs to and from SPC. Strategies that addressed SPC implementation included deploying palliative champions, educating non-SPC clinicians on the value of ambulatory SPC for people with HF and developing ambulatory models through leadership support. CONCLUSIONS/IMPLICATIONS: Facilitating the broader adoption of ambulatory SPC among people with HF may be achieved by prioritizing these mutually valued and necessary features of SPC delivery.

RESUMEN

A potential contributor to the suboptimal rates of guideline directed medical therapy (GDMT) prescribing for heart failure with reduced ejection fraction (HFrEF) is the burden of multimorbidity in patients with HFrEF. We examined the effect of multimorbidity on GDMT prescription in the EPIC-HF trial, finding that multimorbidity was associated with decreased likelihood of GDMT intensification. Further study is needed to guide treatment in high-risk, multimorbid patients with HFrEF.

RESUMEN

Bias in advanced heart failure therapy allocation results in inequitable outcomes for minoritized populations. The purpose of this study was to examine how bias is introduced during group decision-making with an interprofessional team using Breathett's Model of Heart Failure Decision-Making. This was a secondary qualitative descriptive analysis from a study focused on bias in advanced heart failure therapy allocation. Team meetings were recorded and transcribed from four heart failure centers. Breathett's Model was applied both deductively and inductively to transcripts (n = 12). Bias was identified during discussions about patient characteristics, clinical fragility, and prior clinical decision-making. Some patients were labeled as "good citizens" or as adherent/non-adherent while others benefited from strong advocacy from interprofessional team members. Social determinants of health also impacted therapy allocation. Interprofessional collaboration with advanced heart failure therapy allocation may be enhanced with the inclusion of patient advocates and limit of clinical decision-making using subjective data.

RESUMEN

BACKGROUND: Patient-reported outcome (PRO) measures of distinct concepts are often put together into patient profile assessments. When brief, profile assessments can decrease respondent burden and increase measure completion rates. In this report, we describe the creation of 5 self-reported 4-item short forms and the Mechanical Circulatory Support: Measures of Adjustment and Quality of Life (MCS A-QOL) 20-item profile to assess PROs specific to adjustment and health-related quality of life (HRQOL) among patients who undergo left ventricular assist device (LVAD) implantation. METHODS: Using a cross-sectional sample of patients (n = 620) who underwent LVAD implantation at 12 U.S. sites or participated in the MyLVAD.com support group, we created 5 4-item short forms: Satisfaction with Treatment, ventricular assist device (VAD) Team Communication, Being Bothered by VAD Self-care and Limitations, Self-efficacy Regarding VAD self-care, and Stigma, which we combined into a 20-item profile. Analyses included intercorrelations among measures, Cronbach's alpha (i.e., internal consistency reliability)/score-level-specific reliability, and construct validity. RESULTS: The 620 patients were mean age = 57 years, 78% male, 70% White, and 56% on destination therapy LVADs. Intercorrelations among the 5 4-item measures were low to moderate (≤0.50), indicating they are associated yet largely distinct, and correlations with calibrated measures and 6-item short forms were ≥0.76, indicating their ability to reflect full-item bank scores. Internal consistency reliability for the 5 4-item short forms ranged from acceptable (≥0.70) to good (≥0.80). Construct validity was demonstrated for these measures. CONCLUSIONS: Our 5 4-item short forms are reliable and valid and may be used individually or together as a 20-item profile to assess adjustment and HRQOL in patients who undergo LVAD implantation.

RESUMEN

BACKGROUND: U.S. nationwide estimates of the proportion of patients newly diagnosed with heart failure with reduced ejection fraction (HFrEF) eligible for quadruple medical therapy, and the associated benefits of rapid implementation, are not well characterized. OBJECTIVES: This study sought to characterize the degree to which patients newly diagnosed with HFrEF are eligible for quadruple medical therapy, and the projected benefits of in-hospital initiation. METHODS: Among patients hospitalized for newly diagnosed HFrEF in the Get With The Guidelines-Heart Failure registry from 2016 to 2023, eligibility criteria based on regulatory labeling, guidelines, and expert consensus documents were applied for angiotensin receptor-neprilysin inhibitor, beta-blocker, mineralocorticoid receptor antagonist, and sodium-glucose cotransporter 2 inhibitor therapies. Of those eligible, the projected effect of quadruple therapy on 12-month mortality was modeled using treatment effects from pivotal clinical trials utilized by the AHA/ACC/HFSA Guideline for the Management of Heart Failure, and compared with observed outcomes among patients treated with angiotensin-converting enzyme inhibitor/angiotensin receptor blocker and beta-blockers. RESULTS: Of 33,036 patients newly diagnosed with HFrEF, 27,158 (82%) were eligible for quadruple therapy, and 30,613 (93%) were eligible for ≥3 components. From 2021 to 2023, of patients eligible for quadruple therapy, 15.3% were prescribed quadruple therapy and 41.5% were prescribed triple therapy. Among Medicare beneficiaries eligible for quadruple therapy, 12-month incidence of mortality was 24.7% and HF hospitalization was 22.2%. Applying the relative risk reductions in clinical trials, complete implementation of quadruple therapy by time of discharge was projected to yield absolute risk reductions in 12-month mortality of 10.4% (number needed to treat = 10) compared with angiotensin-converting enzyme inhibitor/angiotensin receptor blocker and beta-blocker, and 24.8% (number needed to treat = 4) compared with no GDMT. CONCLUSIONS: In this nationwide U.S. cohort of patients hospitalized for newly diagnosed HFrEF, >4 of 5 patients were projected as eligible for quadruple therapy at discharge; yet, <1 in 6 were prescribed it. If clinical trial benefits can be fully realized, in-hospital initiation of quadruple medical therapy for newly diagnosed HFrEF would yield large absolute reductions in mortality.

RESUMEN

BACKGROUND: Randomized controlled trials typically require study-specific visits, which can burden participants and sites. Remote follow-up, such as centralized call centers for participant-reported or site-reported, holds promise for reducing costs and enhancing the pragmatism of trials. In this secondary analysis of the CONNECT-HF (Care Optimization Through Patient and Hospital Engagement For HF) trial, we aimed to evaluate the completeness and validity of the remote follow-up process. METHODS AND RESULTS: The CONNECT-HF trial evaluated the effect of a post-discharge quality-improvement intervention for heart failure compared to usual care for up to 1 year. Suspected events were reported either by participants or by health care proxies through a centralized call center or by sites through medical-record queries. When potential hospitalization events were suspected, additional medical records were collected and adjudicated. Among 5942 potential hospitalizations, 18% were only participant-reported, 28% were reported by both participants and sites, and 50% were only site-reported. Concordance rates between the participant/site reports and adjudication for hospitalization were high: 87% participant-reported, 86% both, and 86% site-reported. Rates of adjudicated heart failure hospitalization events among adjudicated all-cause hospitalization were lower but also consistent: 45% participant-reported, 50% both, and 50% site-reported. CONCLUSIONS: Participant-only and site-only reports missed a substantial number of hospitalization events. We observed similar concordance between participant/site reports and adjudication for hospitalizations. Combining participant-reported and site-reported outcomes data is important to capture and validate hospitalizations effectively in pragmatic heart failure trials.

RESUMEN

Persons with heart failure (HF) often suffer from poor symptom control, decreased quality of life, and poor communication with their health care providers. These needs are particularly acute in advanced HF, a leading cause of death in the United States. Palliative care, when offered alongside HF disease management, offers improved symptom control, quality of life, communication, and caregiver satisfaction as well as reduced caregiver anxiety. The dynamic nature of the clinical trajectory of HF presents distinct symptom patterns, changing functional status, and uncertainty, which requires an adaptive, dynamic model of palliative care delivery. Due to a limited specialty-trained palliative care workforce, patients and their caregivers often cannot access these benefits, especially in the community. To meet these needs, new models are required that are better informed by high-quality data, engage a range of health care providers in primary palliative care principles, and have clear triggers for specialty palliative care engagement, with specific palliative interventions tailored to patient's illness trajectory and changing needs.

RESUMEN

Cognitive impairment is common among adults with heart failure (HF), as both diseases are strongly related to advancing age and multimorbidity (including both cardiovascular and noncardiovascular conditions). Moreover, HF itself can contribute to alterations in the brain. Cognition is critical for a myriad of self-care activities that are necessary to manage HF, and it also has a major impact on prognosis; consequently, cognitive impairment has important implications for self-care, medication management, function and independence, and life expectancy. Attuned clinicians caring for patients with HF can identify clinical clues present at medical encounters that suggest cognitive impairment. When present, screening tests such as the Mini-Cog, and consideration of referral for comprehensive neurocognitive testing may be indicated. Management of cognitive impairment should focus on treatment of underlying causes of and contributors to cognitive impairment, medication management/optimization, and accommodation of deficiencies in self-care. Given its implications on care, it is important to integrate cognitive impairment into clinical decision making. Although gaps in knowledge and challenges to implementation exist, this scientific statement is intended to guide clinicians in caring for and meeting the needs of an increasingly complex and growing subpopulation of patients with HF.

RESUMEN

Atrial fibrillation (AF) and heart failure (HF) are common cardiovascular conditions that frequently coexist. Among patients with HF, more than one-half also have AF. Both are associated with significant morbidity and mortality. Moreover, the prevalence of each is increasing globally, and this trend is expected to continue owing to an aging population and increased life expectancy. Diagnosis of AF in a patient with HF is associated with greater symptom burden, more frequent hospitalizations, and a worse prognosis. Guideline-directed medical therapy (GDMT) for HF can affect the incidence of AF. Once present, AF can influence the efficacy of some components of GDMT for HF. In this review, we discuss the effect of GDMT for HF across the spectrum of ejection fraction on prevention of AF as well as the benefit of GDMT in patients with vs without AF.

RESUMEN

Importance: The Centers for Medicare & Medicaid Services (CMS) Bundled Payments for Care Improvement (BPCI) program was launched in 2013 with a goal to improve care quality while lowering costs to Medicare. Objective: To compare changes in the quality and outcomes of care for patients hospitalized with heart failure according to hospital participation in the BPCI program. Design, Setting, and Participants: This cross-sectional study used a difference-in-difference approach to evaluate the BPCI program in 18 BPCI hospitals vs 211 same-state non-BPCI hospitals for various process-of-care measures and outcomes using American Heart Association Get With The Guidelines-Heart Failure registry and CMS Medicare claims data from November 1, 2008, to August 31, 2018. Data were analyzed from May 2022 to May 2023. Exposures: Hospital participation in CMS BPCI Model 2 Heart Failure, which paid hospitals in a fee-for-service process and then shared savings or required reimbursement depending on how the total cost of an episode of care compared with a target price. Main Outcomes and Measures: Primary end points included 7 quality-of-care measures. Secondary end points included 9 outcome measures, including in-hospital mortality and hospital-level risk-adjusted 30-day and 90-day all-cause readmission rate and mortality rate. Results: During the study period, 8721 patients were hospitalized in the 23 BPCI hospitals and 94 530 patients were hospitalized in the 224 same-state non-BPCI hospitals. Less than a third of patients (30 723 patients, 29.8%) were 75 years or younger; 54 629 (52.9%) were female, and 48 622 (47.1%) were male. Hospital participation in BPCI Model 2 was not associated with significant differential changes in the odds of various process-of-care measures, except for a decreased odds of evidence-based ß-blocker at discharge (adjusted odds ratio [aOR], 0.63; 95% CI, 0.41-0.98; P = .04). Participation in the BPCI was not associated with a significant differential change in the odds of receiving angiotensin-converting enzyme inhibitors/angiotensin receptor blockers or angiotensin receptor-neprilysin inhibitors at discharge, receiving an aldosterone antagonist at discharge, having a cardiac resynchronization therapy (CRT)-defibrillator or CRT pacemaker placed or prescribed at discharge, having implantable cardioverter-defibrillator (ICD) counseling or an ICD placed or prescribed at discharge, heart failure education being provided among eligible patients, or having a follow-up visit within 7 days or less. Participation in the BPCI was associated with a significant decrease in odds of in-hospital mortality (aOR, 0.67; 95% CI, 0.51-0.86; P = .002). Participation was not associated with a significant differential change in hospital-level risk-adjusted 30-day or 90-day all-cause readmission rate and 30-day or 90-day all-cause mortality rate. Conclusion and Relevance: In this study, hospital participation in the BPCI Model 2 Heart Failure program was not associated with improvement in process-of-care quality measures or 30-day or 90-day risk-adjusted all-cause mortality and readmission rates.

RESUMEN

BACKGROUND: Generic and heart failure-specific measures do not capture unique aspects of living with a ventricular assist device (VAD). Using state-of-the-science psychometric measurement methods, we developed a measurement system to assess post-ventricular assist device adjustment and health-related quality of life (HRQOL). METHODS: Patients were recruited from 10/26/16-2/29/20 from 12 U.S. VAD programs. We created a dataset of participants (n = 620) enrolled before left (L)VAD implantation, with data at 3- or 6- months post-implantation (group1 [n = 154]), and participants enrolled after LVAD implantation, with data at one timepoint (group 2 [n = 466]). We constructed 5 item banks: 3 modified from existing measures and 2 new measures. Analyses included item response theory (IRT) modeling, differential item functioning tests for systematic measurement bias, and indicators of reliability and validity. RESULTS: Of 620 participants, 56% (n = 345) were implanted as destination therapy, 51% (n = 316) were <12 months post-implantation, mean age = 57.3 years, 78% (n = 485) male, 70% (n = 433) White, 58% (n = 353) married/partnered, and 58% (n = 357) with >high school education. We developed 5 new VAD item banks/measures: 6-item VAD Team Communication; 12-item Self-efficacy Regarding VAD Self-care; 11-item Being Bothered by VAD Self-care and Limitations; 7-item Satisfaction with Treatment; and 11-item Stigma. Cronbach's alpha reliability ranged from good (≥0.80) to excellent (≥0.90) for item banks/measures. All measures, except VAD Team Communication, demonstrated at least moderate correlations (≥0.30) with construct validity indicators. CONCLUSIONS: These measures meet IRT modeling assumptions and requirements; scores demonstrate reliability and validity. Use of these measures may assist VAD clinicians to inform patients about VADs as a treatment option and guide post-VAD interventions.
