State of Research on Palliative Care in Heart Failure as Evidenced by Published Literature, Conference Proceedings, and NIH Funding

Palliative Care Across the Spectrum of Heart Failure

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.

An Update: National Institutes of Health Research Funding for Palliative Medicine 2016-2020

Background: The evidence base to support palliative care clinical practice is inadequate and opportunities to improve the evidence base remain despite the field's rapid growth. Objective: The aim of this study was to examine current National Institutes of Health (NIH) funding of palliative medicine research and trends over time. Design: We sought to identify NIH funding of palliative medicine (2016-2020) in two stages: (1) we searched the NIH grant database, RePORTER, for grants with the keywords, "palliative care," "end-of-life care," "hospice," and "end of life," and (2) identified palliative care researchers likely to have secured NIH funding using three strategies. Methods: We abstracted (1) the first and last authors' names from original investigations published in major palliative medicine journals from 2016 to 2018; (2) names from a PubMed-generated list of original articles published in major medicine, nursing, and subspecialty journals using the above keywords; and (3) palliative medicine journal editorial board members and members of key palliative medicine initiatives. We cross-matched the pooled names against NIH grants funded from 2016 to 2021. Results: A crosswalk analysis of the author search and NIH RePORTER search identified 1658 grants. Of those, 541 were categorized as relevant to palliative medicine, which represented 419 unique principal investigators (mean of 1.34 grants per investigator). Compared with 2011-2015, the number of NIH-funded grants increased by 25%, NIH dollars increased by 35%, and the distribution of grant types remained stable. Conclusions: Despite the challenging NIH funding climate, the number of NIH grants and funding to palliative care have increased. Given the increased funding allocation toward Alzheimer's dementia and related dementia research at the congressional level, this increase in funding reflects this funding allocation and does not represent overall growth. Dedicated federal funding for palliative care research remains critical to grow the evidence base for persons living with serious illnesses and their families.

Case Study of an African American Woman With Heart Failure: Ethical and Palliative Care Considerations

Heart failure affects an estimated 6.2 million adults in the United States. African Americans have a higher incidence of heart failure at an earlier age and more rapid disease progression than other ethnicities. African Americans also often receive lower-quality, end-of-life care and less often receive palliative and advanced-care planning than Whites. Several barriers exist for effective heart failure evaluation and treatment among African Americans, including ineffective patient-provider communication, mistrust, health care providers' lack of understanding of palliative care services, and potential downstream effects of social determinants of health (eg, access barriers to healthy food and community health promotion resources). Despite the recognized benefits of palliative care, few adults with heart failure are receiving early discussions about palliative and advanced care planning to ensure delivery of goal-concordant care. This article presents a fictitious case study focused on an African American woman, Ms T, with heart failure who has been given 6 months to live. Racial inequities are presented surrounding Ms T's inadequate access to necessary health care resources and in receiving delayed communication about palliative and advanced care services. The case study also highlights ethical principles of concern, the role of an interdisciplinary team approach for patients with heart failure, and the advocacy role of nurses.

Palliative Care in Heart Failure: A Public Health Emergency

BACKGROUND

Palliative care (PC) is the holistic care of patients with life-limiting illnesses focused on relief of suffering and maximizing quality of life for patients and their families. Patients with heart failure (HF) are the largest group eligible for PC services, but only a small percentage of them receive PC.

AREAS OF UNCERTAINTY

The optimal content and method of delivery of PC interventions to HF patients in resource-limited countries remain unknown. The integration of PC into existing HF disease management continues to be a challenge.

DATA SOURCES

PUBMED was searched to identify articles on the topic published in the last 5 years (2014-April 2019). One hundred thirty-six articles were identified-14 articles out of were included in the revision.

THERAPEUTIC ADVANCES

Research concerning PC in HF is still scarce and comes predominantly from developed countries. PC in HF improves patients' and caregivers' outcomes in terms of dyspnea, sleep, depression, communication, coping, and care-giving burden. Specialized home-based PC services have a positive impact on patients' physical and emotional wellbeing while decreasing utilization of medical services. Fatigue, dyspnea, and pain are frequent symptoms. Evidence concerning use of opioids for dyspnea is increasing. Family caregivers offer a considerable amount of care during the disease trajectory. There is often incongruence between the carer's and the patient's wishes in terms of treatment decisions and preferences. Carers should be assessed for risk and supported in their roles in care management and care coordination.

CONCLUSIONS

Because of the unpredictability of the disease and difficulty in prognostication, PC should be introduced at the point of diagnosis of HF. Basic education in PC needs to be introduced early in the training of cardiology staff, focused on concept definition, differencing PC and terminal care, symptom management, communication, and decision-making.

Rethinking the Meaning of Palliation in Heart Failure

PURPOSE OF REVIEW

Palliative care follows a philosophy of care that focuses upon the quality of life in patients with chronic or life-threatening illness. It also focuses upon the needs of their families which is a wider scope of care. Cardiovascular disease, and specifically heart failure, affects millions of patients and family members who have a symptom burden that exceeds that of many cancers and other chronic diseases.

RECENTLY FINDINGS

Historically palliative care has been viewed as an alternative to curative therapies, but over time, it is now recognized that it should be implemented earlier in the course of chronic diseases. Although non-oncologic patients now comprise over half of the patient seen by palliative care, patients with cardiovascular disease are still not being referred to palliative care. Palliative care goes beyond advance directives and end of life planning. There is a need to continue to expand the view of palliative care to encompass interventions that help improve the overall health of these patients, including their psychosocial well-being and quality of life. The collection of papers in this journal provides insight into the breadth of palliative care for patients with heart failure and other cardiovascular diseases.

National trends in palliative care use among older adults with cardiopulmonary and malignant conditions

BACKGROUND

Palliative care consultation (PCC) is recommended for older adults hospitalized with cardiopulmonary conditions, but frequently is reserved for patients with malignant conditions and those with advanced age.

OBJECTIVES

To compare age-adjusted PCC trends and the relationship between increasing age and PCC among older adults with cardiopulmonary and malignant conditions.

METHODS

Observational analysis of patients age ≥ 65 years, stratified by age and cardiopulmonary (heart failure, chronic obstructive pulmonary disease) vs. malignant (lung and gastrointestinal) conditions. Age-adjusted PCC trends over time and compound annual growth rates (CAGR) were compared.

RESULTS

Discharges with cardiopulmonary vs. malignant conditions were older, more likely to be female, and white. Relative to malignant conditions, discharges with cardiopulmonary conditions had lower age-adjusted PCC rates but higher CAGRS. Increasing age was associated with PCC in both groups but had a stronger effect among cardiopulmonary conditions.

CONCLUSIONS

Older adults with cardiopulmonary conditions experienced lower rates of PCC, but higher rates of growth over time relative to those with malignant conditions.

Implantable cardioverter defibrillators at the end of life: future perspectives on clinical practice

The implantable cardioverter defibrillator (ICD) is effective in terminating life-threatening arrhythmias. However, in the last phase of life, ICD shocks may no longer be appropriate. Guidelines recommend timely discussion with the patient regarding deactivation of the shock function of the ICD. However, research shows that such conversations are scarce, and some patients experience avoidable and distressful shocks in the final days of life. Barriers such as physicians’ lack of time, difficulties in finding the right time to discuss ICD deactivation, patients’ reluctance to discuss the topic, and the fragmentation of care, which obscures responsibilities, prevent healthcare professionals from discussing this topic with the patient. In this point-of-view article, we argue that healthcare professionals who are involved in the care for ICD patients should be better educated on how to communicate with patients about ICD deactivation and the end of life. Optimal communication is needed to reduce the number of patients experiencing inappropriate and painful shocks in the terminal stage of their lives.

Screening and Initiating Supportive Care in Patients With Heart Failure

Background: Patients with heart failure (HF) experience a major symptom burden and an overall reduction of quality of life. However, supportive care (SC) remains an under-utilized resource for these patients. Among the many existing barriers to integrating SC into routine care, identifying patients with SC needs remains challenging. The Kansas City Cardiomyopathy Questionnaire (KCCQ) is an important predictor of SC needs in patients with HF.

Methods and Results: We used the shortened version KCCQ-12 as a screening tool for SC need in our ambulatory HF patient population using a KCCQ-12 summary score of <29 as the cut-off. Of the 456 patients who completed the KCCQ-12, 41 (9%) were predicted to have SC needs. Demographics, medical history, biochemical parameters, echocardiographic assessment and medical treatment were similar between the two groups of patients. However, patients with KCCQ-12 <29 were more symptomatic based on both New York Heart Association (NYHA) classification and American Heart Association (AHA) staging with a higher prevalence of depression. We established a multidisciplinary SC clinic and the profile and outcomes of patients with SC needs that were referred and followed at our SC clinic were also evaluated. Twenty-three patients were referred to our SC clinic: 2 died before being seen, 1 refused SC and 20 received SC. Of these 20 patients, 11 died and 9 are currently being followed. Median survival after starting the SC clinic is 3 months. In the original SC cohort of 23, 17 patients had available KCCQ-12 summary scores. However, only 6 out of 17 (35%) had KCCQ-12 scores <29, indicating the need for additional assessment tools in this patient population.

Conclusions: The magnitude of unmet supportive care needs in patients with HF is significant. While the KCCQ-12 questionnaire is a useful tool to identify patients with SC, serial clinical evaluation, establishment of a SC clinic and prompt referral are essential for patients needing supportive care.

Hospice Use Among Patients with Heart Failure

Despite its many benefits, hospice care is underused for patients with heart failure. This paper discusses the factors contributing to this underuse and offers recommendations to optimise use for patients with heart failure and proposes metrics to optimise quality of hospice care for this patient group.

The National Palliative Care Research Center: Ten Years of Promoting and Developing Research in Palliative Care

BACKGROUND

The evidence base to support high-quality clinical care and number of scientists available to develop this evidence base are inadequate.

OBJECTIVE

To describe the first 10 years of the National Palliative Care Research Center's (NPCRC) programs and their outcomes.

DESIGN

Established in 2005, NPCRC was created in direct response to the recommendations of the Institute of Medicine. Specifically, NPCRC was created to expand the palliative care evidence-based needed for both health policy and clinical practice by supporting research scientists, stimulating research and innovation, and creating a community of researchers focused on the needs of persons with serious illness and their families.

MEASUREMENTS

Subsequent grant funding following NPCRC investment (web searches of NIH Research Portfolio Online Reporting Tools [RePORT], Veterans Administration and Patient Centered Outcomes Research Institute [PCORI] grant databases, grantee on-line surveys, and grantee annual reports) promotions (grantee on-line surveys and annual reports), publications (PubMed searches), and NPCRC participant satisfaction (grantee questionnaires).

RESULTS

As of July 2017, NPCRC has funded 47 junior investigators representing over 10 disciplines. These investigators have leveraged NPCRC's $7.8 million investment into 52 federal grants totaling $74.8 million dollars and 69 foundation grants totaling $16 million. Thirty-five grants ($5.8 million) have been awarded to experienced investigators, resulting in additional grant funding of $104.5 million dollars ($78.5 million federal, $26 million nonfederal). Satisfaction with NPCRC's program has been uniformly high and policy efforts have resulted in enhanced federal funding opportunities in palliative care research.

CONCLUSIONS

NPCRC's focus on people and infrastructure in conjunction with a top-down bottom-up strategy has been critical in improving the palliative care evidence base.

Trends in Contemporary Holistic Nursing Research: 2010-2015

PURPOSE

The purpose of this study was to describe and summarize the characteristics of contemporary holistic nursing research (HNR) published nationally.

DESIGN

A descriptive research design was used for this study.

METHOD

Data for this study came from a consecutive sample of 579 studies published in six journals determined as most consistent with the scope of holistic nursing from 2010 to 2015. The Johns Hopkins level of evidence was used to identify evidence generated, and two criteria-power analysis for quantitative research and trustworthiness for qualitative research-were used to describe overall quality of HNR.

FINDINGS

Of the studies, 275 were considered HNR and included in the analysis. Caring, energy therapies, knowledge and attitudes, and spirituality were the most common foci, and caring/healing, symptom management, quality of life, and depression were the outcomes most often examined. Of the studies, 56% were quantitative, 39% qualitative, and 5% mixed-methods designs. Only 32% of studies were funded. Level III evidence (nonexperimental, qualitative) was the most common level of evidence generated.

CONCLUSIONS

Findings from this study suggest ways in which holistic nurse researchers can strengthen study designs and thus improve the quality of scientific evidence available for application into practice and improve health outcomes.

Palliative Care in Heart Failure: Rationale, Evidence, and Future Priorities

Patients with heart failure (HF) and their families experience stress and suffering from a variety of sources over the course of the HF experience. Palliative care is an interdisciplinary service and an overall approach to care that improves quality of life and alleviates suffering for those living with serious illness, regardless of prognosis. In this review, we synthesize the evidence from randomized clinical trials of palliative care interventions in HF. While the evidence base for palliative care in HF is promising, it is still in its infancy and requires additional high-quality, methodologically sound studies to clearly elucidate the role of palliative care for patients and families living with the burdens of HF. Yet, an increase in attention to primary palliative care (e.g., basic physical and emotional symptom management, advance care planning), provided by primary care and cardiology clinicians, may be a vehicle to address unmet palliative needs earlier and throughout the illness course.

Primary palliative care for heart failure: what is it? How do we implement it?

Heart failure (HF) is a chronic and progressive illness, which affects a growing number of adults, and is associated with a high morbidity and mortality, as well as significant physical and psychological symptom burden on both patients with HF and their families. Palliative care is the multidisciplinary specialty focused on optimizing quality of life and reducing suffering for patients and families facing serious illness, regardless of prognosis. Palliative care can be delivered as (1) specialist palliative care in which a palliative care specialist with subspecialty palliative care training consults or co-manages patients to address palliative needs alongside clinicians who manage the underlying illness or (2) as primary palliative care in which the primary clinician (such as the internist, cardiologist, cardiology nurse, or HF specialist) caring for the patient with HF provides the essential palliative domains. In this paper, we describe the key domains of primary palliative care for patients with HF and offer some specific ways in which primary palliative care and specialist palliative care can be offered in this population. Although there is little research on HF primary palliative care, primary palliative care in HF offers a key opportunity to ensure that this population receives high-quality palliative care in spite of the growing numbers of patients with HF as well as the limited number of specialist palliative care providers.

The State of the Science on Integrating Palliative Care in Heart Failure

BACKGROUND

Heart failure (HF) is a chronic progressive illness associated with physical and psychological burdens, high morbidity, mortality, and healthcare utilization. Palliative care is interdisciplinary care that aims to relieve suffering and improve quality of life for persons with serious illness and their families. It is offered simultaneously with disease-oriented care, unlike hospice or end-of-life care. Despite the demonstrated benefits of palliative care in other populations, evidence for palliative care in the HF population is limited.

OBJECTIVE

The objective of this article is to describe the current evidence and the gaps in the evidence that will need to be improved to demonstrate the benefits of integrating palliative care into the care of patients with advanced HF and their family caregivers.

METHODS

We reviewed the literature to examine the state of the science and to identify gaps in palliative care integration for persons with HF and their families. We then convened an interdisciplinary working group at an NIH/NPCRC sponsored workshop to review the evidence base and develop a research agenda to address these gaps.

RESULTS

We identified four key research priorities to improve palliative care for patients with HF and their families: (1) to better understand patients' uncontrolled symptoms, (2) to better characterize and address the needs of the caregivers of advanced HF patients, (3) to improve patient and family understanding of HF disease trajectory and the importance of advance care planning, and (4) to determine the best models of palliative care, including models for those who want to continue life-prolonging therapies.

CONCLUSIONS

The goal of this research agenda is to motivate patient, provider, policy, and payor stakeholders, including funders, to identify the key research topics that have the potential to improve the quality of care for patients with HF and their families.

Palliative Care in Heart Failure: What Triggers Specialist Consultation?

Heart failure (HF) continues to cause substantial death and suffering despite the availability of numerous medical, surgical, and technological therapeutic advancements. As a patient-centered holistic discipline focused on improving quality of life and decreasing anguish, palliative care (PC) has a crucial role in the care of HF patients that has been acknowledged by multiple international guidelines. PC can be provided by all members of the HF care team, including but not limited to practitioners with specialty PC training. Unfortunately, despite recommendations to routinely include PC techniques and providers in the care of HF patients, use of general PC strategies as well as expert PC consultation is limited by a dearth of evidence-based interventions in the HF population and knowledge as to when to initiate these interventions, uncertainty regarding patient desires, prognosis, and the respective roles of each member of the care team, and a general shortage of specialist PC providers. This review seeks to provide guidance as to when to employ the limited resource of specialist PC practitioners, in combination with services from other members of the care team, to best tend to HF patients as their disease progresses and eventually overcomes.
